Animal Style is the most famous order in the entire In-N-Out universe — so famous that people who’ve never been to In-N-Out have heard of it. But what actually is it? Here’s the full breakdown: what’s in it, what it costs, where the name came from, and how to order it. For the broader hidden menu, see our In-N-Out secret menu full list and the In-N-Out menu with prices (2026) guide.
What Is Animal Style at In-N-Out?
“Animal Style” is a preparation, not a single item — you can order any burger or fries Animal Style. On a burger, it means four specific changes:
- Mustard-grilled patty. Yellow mustard is spread on the raw side of the patty right before flipping, so it sears into the meat with a tangy crust.
- Pickles. Dill pickle chips — the only way to get pickles on an In-N-Out burger, since the standard build doesn’t include them.
- Grilled onions. Sweet, caramelized, chopped — instead of (or in addition to) raw onion.
- Extra spread. A heavier hand of In-N-Out’s signature Thousand-Island-style sauce.
On fries, Animal Style means: fries topped with melted American cheese, grilled onions, and spread (around $4.25–$5.45).
Where Did “Animal Style” Come From?
The origin story comes from In-N-Out owner Lynsi Snyder’s book: in the early days, a regular customer watched an employee make himself a burger — mustard-fried, with pickles, grilled onions, and extra spread — and asked what was in it. He loved it, kept ordering it, and eventually the employee told him: “Just call it Animal Style.” That request is considered the first known secret-menu order in In-N-Out history.
Today it’s the chain’s signature off-menu order — famously endorsed by Gordon Ramsay — and the gateway to wilder hacks like Gorilla Style.
How Much Does Animal Style Cost?
On burgers, Animal Style is free — it’s a preparation change, not an upcharge. An Animal Style Double-Double costs the same as a regular Double-Double (about $5.90–$6.25 depending on state).
Animal Style fries are a separate menu item at roughly $4.25–$5.45 — the upcharge covers the cheese, grilled onions, and extra spread.
How to Order Animal Style (Step by Step)
- Say the magic words: “Double-Double, Animal Style” — staff know it instantly.
- Works on any burger: hamburger, cheeseburger, 3×3, even Protein Style (lettuce-wrapped Animal Style is a thing).
- For fries: “Animal Style fries, please.” Add chopped chilies free for heat.
- Fine-tune it: want it messier? Ask for extra spread and whole grilled onions. Watching carbs? Animal Style + Protein Style combo.
