What Is an In-N-Out Animal Style Burger?

An In-N-Out Animal Style Burger is a customized burger prepared with mustard-cooked beef, grilled onions, pickles, and extra spread. It generally retains lettuce and tomato and includes cheese when the selected burger normally has cheese.

Animal Style is a preparation method, not a separate burger size. In-N-Out officially recognizes it on its Not-So-Secret Menu.

In-N-Out Animal Style Burger Price in 2026

The In-N-Out Animal Style burger price depends on the base burger, restaurant, and customization.

In-N-Out doesn’t publish a nationwide price list online. The following table therefore uses location-dependent pricing rather than presenting estimated amounts as confirmed restaurant prices.

Third-party 2026 menu reports indicate that the Animal Style burger modification is generally offered without an additional charge, although the official website doesn’t publish a universal pricing policy.

For the exact total, ask your local In-N-Out restaurant about the burger price, modifications, and applicable sales tax.

How to Order an In-N-Out Animal Style Burger

Ordering Animal Style is straightforward:

• Choose a Hamburger, Cheeseburger, or Double-Double. Ask about 3×3 or 4×4 availability if preferred.
• Request the burger “Animal Style.”
• Mention additional preferences, such as no pickles or no onions.
• Request Protein Style if you prefer lettuce instead of a bun.
• Confirm the final price and ingredients before completing your order.

For example, simply ask for a “Double-Double Animal Style.”

In-N-Out Animal Style Burger Allergens

Animal Style burgers can contain several important allergens.

Allergen	Potential Source
Wheat	Standard burger bun
Milk	American cheese
Egg	Signature spread
Soy	Cheese ingredients; possible cross-contact
Mustard	Mustard-cooked patty and spread
Sesame	Possible facility cross-contact

The standard bun contains wheat, the cheese contains milk, and the spread contains egg. In-N-Out also identifies certain facility cross-contact considerations.

Protein Style replaces the bun with lettuce but does not guarantee an allergen-free meal. Always confirm ingredients and preparation procedures with restaurant staff.
