Tips & Notes

Pro tips

Grill your onions in batches on high heat until deeply caramelized and slightly charred; this takes 5-7 minutes and develops the signature sweet, umami depth of In-N-Out's version.
Toast your bun lightly on the griddle or skillet to prevent sogginess from the Animal Style sauce and fresh toppings.
Apply the Thousand Island-style spread and pickles before adding the hot patties so the heat slightly softens the condiments into the bun.
Chop your chilies finely and add them just before serving to maintain their bright color and fresh heat rather than losing them to the warm patties.

Substitutions

Beef patties → plant-based or veggie patties (maintains Animal Style toppings and flavor profile)
Strawberry shake → vanilla or chocolate shake (changes the pairing but keeps the meal format intact)
Fresh jalapeños or serranos → dried chili flakes or hot sauce (easier prep, more concentrated heat)
Whole grilled onions → caramelized onion jam (richer, spreadable alternative with similar sweetness)

Storage & make-ahead

This is a fresh, made-to-order burger best enjoyed immediately; leftovers do not store well due to bun sogginess, though the shake can be refrigerated for 2-3 hours.

Common Questions

What is Animal Style at In-N-Out?

Animal Style includes grilled onions, extra spread (Thousand Island-style sauce), pickles, and mustard-grilled patties, creating a tangy, savory flavor profile.

Can I make this recipe at home without visiting In-N-Out?

Yes. Cook two beef patties with mustard, add grilled onions, pickles, and a homemade Thousand Island sauce, then top with chopped chilies and melted cheese on a toasted bun.

What type of chilies work best for this burger?

Fresh jalapeños, serranos, or mild green chilies add heat without overpowering. Adjust quantity based on your spice tolerance.

How do I grill onions like In-N-Out does?

Slice onions thinly, place directly on a hot griddle or skillet with a touch of oil, and cook until caramelized and charred, about 5-7 minutes, stirring occasionally.

Can I customize this order for dietary restrictions?

The core burger and shake can be modified: skip the bun for keto, use a plant-based patty for vegetarian, or omit the shake for dairy-free—most In-N-Out locations accommodate these requests.
