In-N-Out Menu Allergen & Special Diets Guide
Because In-N-Out builds every burger to order from a short ingredient list—100% USDA ground beef chuck, American cheese, sponge-dough buns, whole potatoes, and real ice cream—navigating food allergies and macro targets is far simpler than at most drive-thrus.
Official nutrition source checked . Always inform the order-taker directly of any severe food allergy before ordering.

How to Request the Official Gluten-Allergy Prep
- Ask for “Gluten Allergy” on the receipt: When ordering Protein Style, tell the associate you have a celiac or wheat allergy. They flag the POS ticket as an allergy order.
- Glove change & separate grill zone: Cooks put on fresh gloves, use a dedicated spatula that has not touched toasted buns, and assemble the lettuce-wrapped burger in a separate red tray.
- Dedicated fryers: Unlike fast-food chains that fry onion rings, chicken nuggets, and French fries in the same oil vat, In-N-Out’s fryers cook only fresh-cut Russet potatoes in 100% sunflower oil.
Keto, Low-Carb & Carnivore Orders
Swapping the sponge-dough bun for hand-leafed iceberg lettuce drops 29 grams of carbohydrates immediately. Swapping signature spread for mustard or ketchup trims another 2–3 grams of sugar.
| Keto / Low-Carb Configuration | Calories | Total Fat | Total Carbs | Fiber | Net Carbs | Protein |
|---|---|---|---|---|---|---|
| Double-Double Protein Style (Ketchup & Mustard) | 490 kcal | 37 g | 8 g | 3 g | 5 g | 31 g |
| Double-Double Protein Style (with Spread) | 470 kcal | 35 g | 10 g | 2 g | 8 g | 29 g |
| Cheeseburger Protein Style (with Spread) | 290 kcal | 21 g | 9 g | 2 g | 7 g | 16 g |
| Hamburger Protein Style (Ketchup & Mustard) | 170 kcal | 10 g | 9 g | 2 g | 7 g | 12 g |
Carnivore & Zero-Produce Tip: Order a Flying Dutchman — community order, not official (two beef patties and two slices of cheese, no bun or produce) or order extra single beef patties and cheese patties à la carte. Watch out for grilled onions if tracking strict ketosis—slow-caramelized chopped onions add natural onion sugars.
Vegetarian, Vegan & Dairy-Free Guide
Vegetarian Orders (Contains Dairy & Egg)
- Grilled Cheese: Listed on the official Not-So-Secret Menu with 370 kcal, 18 g fat, 37 g carbs, and 14 g protein. Made with two slices of melted American cheese, lettuce, tomato, and spread on a toasted bun (raw or grilled onions optional).
- Cheese Fries — community order, not official and Animal Style Fries — community order, not official: Meat-free fry customizations topped with melted American cheese (and spread + grilled onions for Animal Style).
Vegan & Dairy-Free Orders
- Dairy-Free Burgers: The Hamburger (360 kcal, 16 g protein) and Double-Meat (28 g protein, two beef patties with zero cheese) contain zero dairy. The bakery bun is made from flour, water, yeast, sugar, and salt without milk or butter.
- Egg-Free Modification: In-N-Out’s signature spread is mayonnaise-based and contains egg yolk. Ask for “ketchup and mustard instead of spread” on any burger to make it completely egg-free and dairy-free.
- Vegan Meal Idea: Order a Veggie Burger with no cheese and ketchup/mustard instead of spread, add Pickles and Chopped Chilies, and pair with French Fries cooked in 100% sunflower oil.
Allergen & Special Diet FAQs
Are In-N-Out French Fries gluten-free and cooked in a dedicated fryer?

How do I order gluten-free at In-N-Out for celiac or wheat allergy?
Order any burger Protein Style (wrapped in hand-leafed iceberg lettuce instead of a wheat bun) and explicitly tell the cashier you have a gluten or wheat allergy. The kitchen crew will change gloves, use clean utensils, and prepare your order in a designated allergy tray away from toasted buns.
Does In-N-Out use peanut oil, seed oils, or beef tallow for fries?
In-N-Out cooks its French Fries exclusively in 100% sunflower oil (cholesterol-free and trans-fat-free). It does not use peanut oil, tree-nut oils, soybean oil, or beef tallow in its fryers.
What is the best Keto or low-carb order at In-N-Out?
A Protein Style Double-Double with ketchup and mustard instead of spread has 490 kcal, 8 g total carbs, 3 g fiber (5 g net carbs), and 31 g protein. For near-zero carbs, the Flying Dutchman (community order, not official) pairs two beef patties and two slices of American cheese with no bun or lettuce.
