Cook Out Allergens Menu – Complete Guide to Food Allergies & Sensitivities
Cook Out doesn’t post allergen details on its menu boards, and the kitchen uses shared equipment across nearly every order shared fryers, a shared grill, and shared milkshake blenders. For anyone managing a food allergy or sensitivity, that setup requires some planning before you order. This guide maps the nine FDA recognized major allergens across every Cook Out menu category: burgers, hot dogs, sides, chicken, milkshakes, sauces, the Tray menu, and drinks. It also covers cross contact risks, the lowest risk items on the menu, a practical ordering checklist, and answers to the most common allergen questions customers ask. Always confirm with your specific Cook Out location before ordering if your allergy is severe ingredient sourcing can vary by restaurant and by time of year.
Official Cook Out Allergen Information
Cook Out does not display a comprehensive allergen chart on its in store menu boards. The chain has made allergen reference guides available in PDF format at various times, but these are not always kept current and may not reflect recent ingredient changes at every location. Because Cook Out is a regional chain with supplier relationships that can shift, ingredient formulations for items like buns, sauces, seasonings, and fry batters can vary between restaurants and over time.
If you need verified allergen information before ordering, the most reliable options are:
- Call your specific Cook Out location directly and ask about the allergen status of the items you want to order.
- Visit cookout.com for any current official nutrition or allergen documentation they publish.
- Speak to the manager on duty at the restaurant, who may be able to check ingredient labels for specific items.
The tables and information throughout this guide are based on publicly available ingredient information, standard fast food industry ingredient patterns, and documented customer allergen reports. They are a practical reference not a substitute for confirmed allergen information from Cook Out directly, especially for severe or anaphylactic allergies.
Most Common Allergens Found at Cook Out
Four allergens show up repeatedly across the Cook Out menu not occasionally, but consistently across most categories. Understanding why each one appears so frequently makes it easier to plan your order around them.
| Allergen | Why It Appears So Often | Main Sources |
|---|---|---|
| 1. Wheat / Gluten | Buns are served with almost every entrée, and most fried items use a wheat based batter or coating. The shared fryer then spreads wheat cross contact to items that don’t directly contain it. | Buns, onion ring batter, hushpuppies, chicken breading, corn dog coating, quesadilla tortilla, White Cheddar Bites breading |
| 2. Soy | Commercial burger buns and hot dog buns commonly include soy flour or soy lecithin as a standard ingredient. Many cooking oils used in fast food are also soy based, though oil type can vary by location. | Most buns, many sauces, fryer oil (varies by location), some seasoning blends |
| 3. Dairy / Milk | Cheese is offered on most burger builds, the quesadilla and White Cheddar Bites are cheese centric items, and the milkshake menu is entirely dairy based. Dairy is hard to avoid unless you build your order deliberately around it. | All cheese, coleslaw dressing, White Cheddar Bites, Cheese Quesadilla, all milkshakes, cheesecake |
| 4. Egg | Egg shows up in mayonnaise based sauces and dressings, and in the batter for some fried items like hushpuppies. It’s less pervasive than wheat, soy, or dairy, but appears in enough places to be worth tracking. | Mayo, coleslaw dressing, hushpuppy batter, some bun recipes |
All Nine FDA Allergens at a Glance
Since January 2023, the FDA recognizes nine major food allergens. Here’s how each one applies to the Cook Out menu at a high level.
| Allergen | Presence | Where to Watch |
|---|---|---|
| Wheat / Gluten | High Direct & Cross Contact | Buns, batters, breading, tortilla; fryer cross contact on all fried items |
| Milk / Dairy | High Direct | All cheese, coleslaw, White Cheddar Bites, quesadilla, every milkshake |
| Eggs | Moderate | Mayo based sauces, coleslaw dressing, hushpuppy batter, some bun recipes |
| Soy | High Direct & Possible Cross Contact | Most buns, many sauces; fryer oil type varies by location confirm locally |
| Peanuts | Low–Moderate | Peanut butter milkshake; shared blender cross contact spreads risk to other shakes |
| Tree Nuts | Low–Moderate | Banana nut milkshake and nut flavored shake add ins; shared blender |
| Fish | Not a standard menu item | Not on the standard Cook Out menu; confirm with location if concerned |
| Shellfish | Not a standard menu item | Not on the standard Cook Out menu |
| Sesame | Low–Moderate | Some bun varieties include sesame seeds depending on supplier; confirm at your location |
Ingredient formulations and supplier sourcing can change. Always confirm allergen status at your specific Cook Out location before ordering.

Cook Out Tray Menu – Allergen Guide
The Cook Out Tray comes with one entrée, two sides, and a drink. From an allergen standpoint, the Tray format means you’re choosing three items at once, and the allergen load adds up quickly depending on what you pick. Here’s how the most common Tray combinations stack up.
| Tray Entrée | Common Allergens | Lower Risk Side Picks |
|---|---|---|
| Cheeseburger Tray | Wheat, Dairy, Soy | Coleslaw, Chili Cup (avoid fried sides if gluten sensitive) |
| Chicken Strip Tray | Wheat, Soy | Coleslaw, Chili Cup; avoid additional fried sides if wheat sensitive |
| Hot Dog Tray | Wheat, Soy | Coleslaw works well; Chili Cup if you want something warm |
| Grilled Chicken Tray | Soy possible (marinade confirm locally); no wheat if bun skipped | Coleslaw + Chili Cup = lowest allergen Tray build overall |
| BBQ Sandwich Tray | Wheat, Soy; BBQ sauce may carry additional soy | Coleslaw and regular fries (watch fryer cross contact) |
| Quesadilla Tray | Wheat, Dairy | Chili Cup + Coleslaw to balance the cheesy entrée |
The lowest allergen Tray build overall is a grilled chicken breast (no bun, no sauce) with coleslaw and a chili cup. This avoids the fryer and bun entirely. See the full Cook Out Sides Menu for the complete side allergen breakdown.
Kids Menu – Allergen Information
Cook Out’s simpler items are popular with younger customers and families. All of these carry the standard cross contact risk from shared kitchen equipment, and most include wheat and soy from the bun or batter.
| Item | Main Allergens | Notes |
|---|---|---|
| Hamburger (kids size) | Wheat, Soy | Bun carries both; patty itself is plain beef |
| Hot Dog | Wheat, Soy | Bun and frank both include wheat and soy as standard |
| Corn Dog | Wheat, Soy | Honey batter coating contains wheat; fried in shared fryer |
| Chicken Nuggets (5pc) | Wheat, Soy | Breaded white meat; wheat in coating; shared fryer |
| Regular Fries | Fryer cross contact (wheat, soy possible) | No direct wheat ingredient in the potato; fryer is shared with battered items |
Milkshake Allergens by Flavor Category
Cook Out offers over 40 milkshake combinations. Every single one contains dairy that’s non negotiable across the full menu. Beyond dairy, the risk level depends entirely on what flavor category you’re ordering from. All shakes also run through shared blending equipment, which means cross contact between flavor categories is a real factor for nut allergy sufferers. See the full Cook Out Milkshakes Menu for the complete flavor list.
| Flavor Category | Examples | Allergens Beyond Dairy | Nut Cross Contact Risk |
|---|---|---|---|
| Fruit Based | Strawberry, Banana, Peach | None typically direct | ⚠ Blender shared |
| Peanut Based | Peanut Butter, Peanut Butter Banana | Peanuts Direct | ✔ High Risk |
| Tree Nut | Banana Nut | Tree Nuts Direct | ✔ High Risk |
| Cookie Based | Oreo, Chocolate Chip Cookie Dough | Wheat, Soy (from cookies) | ⚠ Blender shared |
| Candy Mix In | M&M, Reese’s Pieces, Butterfinger | Soy (lecithin in candy); Peanuts possible depending on candy | ⚠–✔ Varies by candy |
| Chocolate Based | Chocolate, Chocolate Fudge | Soy lecithin common in chocolate; confirm locally | ⚠ Blender shared |
| Plain / Vanilla | Vanilla, Plain | None typically beyond dairy | ⚠ Blender shared |
For peanut or tree nut anaphylaxis: every milkshake at Cook Out carries cross contact risk through the shared blender, even flavors that don’t directly contain nuts. There is no dedicated allergen safe blender at standard locations.
Cook Out Drinks – Allergen Information
Standard Cook Out beverages are the cleanest allergen option on the entire menu. Fountain sodas, tea, and lemonade carry no declared allergens in their own ingredients and don’t pass through shared kitchen equipment the way food items do. This makes them a reliable safe pick for anyone managing multiple food allergies. See the Cook Out Drinks Menu for the full beverage list.
| Beverage | Allergen Risk | Notes |
|---|---|---|
| Coca Cola / Diet Coke | None | No declared allergens in standard Coca Cola products |
| Cheerwine | None | A Southern staple at Cook Out; no declared allergens |
| Sweet Tea | None | Tea, water, and sugar; allergen free |
| Unsweetened Tea | None | Allergen free; safest drink choice on the menu |
| Lemonade | None | Lemon, water, sugar; no declared allergens |
| Water | None | Completely allergen free |
| Milkshakes | Dairy All Flavors | Every shake contains dairy; nut and soy risk varies by flavor; blender is shared across all flavors |
Shared Equipment and Cross Contact Risks
Cross contact is when an allergen free food picks up trace amounts of an allergen through shared equipment or surfaces not because of its own ingredients, but because of what it was prepared alongside. At Cook Out, three pieces of shared equipment create most of the cross contact risk on the menu.
| Equipment | What Gets Cooked In / On It | Allergens That Spread | Items Affected |
|---|---|---|---|
| Shared Fryer | All fried items: onion rings, hushpuppies, chicken strips, nuggets, corn dog, White Cheddar Bites, fries, rounds | Wheat (from batters), soy (from oil type varies by location), egg (from some batters) | Every fried item, including plain fries and Cook Out Rounds which have no direct wheat ingredient |
| Shared Grill | Burger patties, grilled chicken, hot dogs, quesadillas | Soy and wheat residue from seasoned items; dairy from cheese melt | All grilled items, including plain grilled chicken which has no direct wheat or dairy |
| Shared Blender | All milkshake flavors: peanut butter, banana nut, fruit, cookie, candy mix ins, vanilla | Peanuts, tree nuts, soy (from candy), wheat (from cookie mix ins) | Every milkshake flavor, even plain vanilla and fruit flavors |
Lowest Allergen Risk Menu Items at Cook Out
These are the items with the fewest direct allergen ingredients and the least exposure to shared equipment. None of them can be called completely allergen free, but they represent the safest starting point for most sensitivity scenarios.
| Item | Why It’s Lower Risk | Remaining Concern |
|---|---|---|
| Plain Burger Patty (no bun, no sauce) | No wheat, no dairy, no egg in the patty itself | Grill cross contact; soy possible in some bun or seasoning residue on grill |
| Plain Grilled Chicken Breast (no bun, no sauce) | No wheat, no dairy, no egg as direct ingredients | Soy possible in marinade confirm locally; grill cross contact |
| Chili Cup (no cheese topping) | No dairy, no egg, no fryer exposure; comes from a separate pot | Wheat or soy possible in chili blend depending on recipe confirm locally |
| Coleslaw | No wheat, no fryer exposure; cold prep | Creamy dressing is mayo based contains egg and possible soy |
| Unsweetened Tea | No allergens of any kind | None |
| Fountain Sodas (Coke, Sprite, Cheerwine) | No allergens of any kind in standard fountain drinks | None |
| Yellow Mustard | Typically free of all nine FDA allergens | Confirm specific brand used at your location |
Allergy Safe Ordering Checklist
A quick checklist to run through before and during your Cook Out order if you’re managing a food allergy.
| Step | Action | Why It Matters |
|---|---|---|
| 1 | State your allergy, not just your modification | Say “I have a wheat allergy” not just “no bun” this prompts staff to consider the full prep |
| 2 | Ask about the fryer | “Do fries share a fryer with breaded items?” confirms whether cross contact is happening at that location |
| 3 | Skip sauces by default | Cook Out Sauce, ranch, honey mustard, and BBQ all carry soy or egg; plain mustard and ketchup are the safest choices |
| 4 | Verify your side picks | If gluten sensitive, choose coleslaw or chili cup over any fried side those two avoid the fryer entirely |
| 5 | Confirm milkshake blender situation | If you have a nut allergy and still want a shake, ask staff if they can rinse the blender before making yours |
| 6 | Ask about supplier changes | Bun and sauce suppliers can change; what was safe on a previous visit may have changed ingredients |
| 7 | Carry emergency medication if relevant | For anaphylactic allergies, no fast food kitchen can guarantee zero cross contact; an EpiPen is still essential |
Gluten Free and Dairy Free Options at Cook Out
Gluten Free (Lower Direct Risk Fryer Cross Contact Still Applies)
- Plain burger patty, no bun, no sauce
- Grilled chicken breast, no bun, no sauce; confirm marinade locally
- Coleslaw, no wheat ingredient; mayo dressing carries egg
- Chili Cup, confirm recipe locally; no fryer exposure
- All fountain drinks and tea, no gluten concerns
Dairy Free Options
- Plain burger patty, no cheese, no sauce
- Plain grilled chicken breast, no sauce, no cheese

- Note: No dairy free milkshake option is available on the standard Cook Out menu as of 2026.
Cross contact risk from shared kitchen equipment applies to all items listed above. For celiac disease or anaphylactic dairy allergy, the shared fryer and shared grill mean that allergen free preparation cannot be guaranteed at standard Cook Out locations.
Frequently Asked Questions
Does Cook Out use shared fryers?
Yes. All fried items at Cook Out fries, onion rings, hushpuppies, chicken strips, nuggets, corn dogs, White Cheddar Bites, and Cook Out Rounds cook in shared fryer oil. This means every fried item carries wheat cross contact risk from the battered items that fry alongside them, even if the item itself contains no wheat as an ingredient.
Does Cook Out offer a dedicated allergen menu?
Cook Out doesn’t display a formal allergen menu on its boards. The chain has made allergen reference PDFs available at various times, but these aren’t always current. The most reliable approach is to visit cookout.com for any current documentation, or call your specific location before visiting.
Which Cook Out milkshakes contain peanuts?
The Peanut Butter milkshake and Peanut Butter Banana milkshake directly contain peanuts. Any Reese’s Pieces mixin shake also carries peanuts. Beyond that, the shared blender means peanut cross contact is possible in every other shake flavor as well. For a peanut allergy, skipping the milkshake entirely is the safest call.
Are Cook Out drinks allergen free?
Yes fountain sodas (Coke, Diet Coke, Sprite, Cheerwine, etc.), sweet tea, unsweetened tea, lemonade, and water are allergen free. They don’t pass through shared kitchen equipment. Milkshakes are the exception: every shake contains dairy, and many carry additional allergens depending on the flavor.
Is there a sesame free bun option at Cook Out?
Bun ingredients, including whether sesame seeds are present, vary by location and by which supplier that restaurant is currently using. There isn’t a standardized “sesame free bun” option listed across all Cook Out locations. If sesame is a concern, call your local restaurant and ask about their current bun supplier.
Which Cook Out sides contain wheat?
Onion rings, hushpuppies, chicken nuggets, corn dog, cheese quesadilla, White Cheddar Bites, and the Walking Taco all contain wheat as a direct ingredient. Regular fries, Cajun fries, and Cook Out Rounds don’t contain wheat directly but are fried in shared oil alongside items that do. Coleslaw and the chili cup are the two sides without any direct wheat ingredient and without fryer exposure.
Can I customize a Cook Out Tray for allergies?
Yes. The Tray format is flexible you choose the entrée, two sides, and a drink independently. For allergy purposes, the most practical low risk Tray build is a grilled chicken breast or plain burger patty (no bun, no sauce), with coleslaw and a chili cup as sides, and any fountain drink. This avoids the fryer entirely and eliminates most direct allergen ingredients. See the Cook Out Tray Menu for full Tray options.
Can I eat at Cook Out with celiac disease?
Eating safely with celiac disease at Cook Out is very difficult. The shared fryer means even plain fries cook in oil alongside wheat battered onion rings and hushpuppies. The grill is also shared across all items. There is no dedicated gluten free preparation area at standard Cook Out locations. The kitchen is not set up to prevent cross contact reliably for celiac level sensitivity.
Are Cook Out fries gluten free?
The fries are cut from fresh potatoes and contain no wheat as a direct ingredient. For a mild gluten intolerance, they may be a workable choice. For celiac disease, the shared fryer with wheat battered onion rings and hushpuppies makes them unsafe due to cross contact.
Are any milkshakes dairy free at Cook Out?
No. Every Cook Out milkshake uses a dairy based ice cream foundation. There are no plant based or dairy free shake alternatives on the standard menu as of 2026. Fountain drinks, tea, and lemonade are the dairy free drink options.
Is Cook Out safe for a peanut allergy?
The food menu at Cook Out doesn’t use peanuts as a direct ingredient in any standard item. The risk is concentrated in the milkshake section specifically the peanut butter shake and related nut flavors, plus shared blender cross contact that affects every shake. If you’re ordering food only and skipping shakes, your peanut exposure risk is considerably lower. Confirm with your specific location for complete reassurance.
What is the safest meal to order at Cook Out with multiple allergies?
The lowest allergen full meal at Cook Out is a plain grilled chicken breast with no bun and no sauce, a chili cup, coleslaw (if egg is tolerable in the mayo dressing), and an unsweetened tea or fountain soda. This combination avoids the fryer entirely, eliminates the bun’s wheat and soy, and skips the milkshake blender and all its cross contact risk.
