Make these homemade Animal Style Fries for epic crunch, gooey cheese, and sweet browned onions with a quick-tossed tangy sauce—all no drive-thru needed. Perfect for sharing, couch snacking, or satisfying those strong In-N-Out cravings at home.
I whipped these up after coming home from California, dreaming of In-N-Out. Now my crew requests them at every get-together. Every bite hits all the memory buttons, and it's easy to switch things up if someone’s picky.
Tasty Ingredients
- Frozen fries: Pick your favorite—waffle or extra crispy makes these turn out great. Go name brand for that real-deal texture.
- American cheese or cheddar: Melty and gooey, just like you want. Wrapped singles bring the true flavor, but shredded works too.
- Onions: Yellow onions do best for deep sweetness and caramel color. Grab ones that feel hefty and firm.
- Butter: Makes the onions rich. Stick with unsalted so you're in control of the saltiness.
- Neutral oil: Vegetable or canola—this helps keep the butter from burning while the onions chill out and cook slowly.
- Salt: Draws out juices and balances flavors. Kosher or sea salt spreads out best.
- Mayonnaise: The base for the creamy sauce. Full-fat packs the most taste.
- Ketchup: Adds tang and a hint of sweet. No-corn-syrup types let other flavors stand out.
- Sweet relish: Crunchy, tangy pops in the sauce. Dill relish gives a less sugary bite.
- Rice vinegar or white vinegar: Brings out brightness, balances the rest. Go for a mild, clear kind.
- Sugar: Just a pinch for a softer, rounder sauce flavor.
- Chili flakes: Totally up to you if you like a little heat. Go for fresh, vibrant flakes for the kick.
Simple How-To
- Get the Onions Going:
- Chop up a couple yellow onions into even pieces. In a sturdy pan, melt your butter and a splash of oil over medium-low. Toss in those onions, sprinkle salt, then cook slowly, stirring here and there—at least 30 minutes. They’ll get deep golden and sweet. If they get too dark, drop the heat. That’s what builds all the flavor.
- Mix Up the Sauce:
- While the onions work, combine mayo, ketchup, relish, vinegar, a tiny bit of sugar, and chili flakes if you want. Use a small bowl. Cover and chill so those flavors snuggle together until you’re ready to use.
- Fries Time:
- Prepare your frozen fries just as it says on the bag—oven or deep-fryer both work. Spread them out in a single layer on a baking-friendly platter when they’re crisp.
- Cheese It Up:
- Lay slices or sprinkle shreds of cheese over the hot fries. Broil for about three minutes until melty and bubbling, but not dried out or browned. Keep an eye so it’s all gooey, not crispy.
- Put It All Together:
- Scatter caramelized onions over the cheese and fries. Spoon plenty of sauce on top just before digging in. Serve right away while everything is super melty and warm.

The best thing, hands down, is those rich caramelized onions. Every time I make them, I remember cozy Fridays in my first place—just me, a movie, and onions sizzling away for a half hour. The whole place would smell amazing, and it always felt special.
Smart Storage
Stash extras by keeping fries and toppings apart in sealed containers in the fridge. They’ll stay good for about two days. To reheat, pop the fries back on a baking sheet and blast them in a hot oven till crisp. Add cheese, onions, and sauce just before eating so everything is tasty and melty again.
Subbing Ingredients
If American cheese isn’t your jam, use shredded mozzarella or Colby Jack for a different vibe. For a fresher sauce, swap in Greek yogurt for mayo. Skipping sugar in the sauce is totally fine, too.

FAQs About the Recipe
- → What's the trick to cooking onions so they're evenly caramelized?
Start onions in some oil and butter over low to medium heat. Stir them now and then while they soften. If they look like they're browning before getting sweet, turn the heat down so they don’t burn.
- → Which cheese melts best for this?
Stick with American cheese for that classic gooey topping, or use shredded cheddar if you're craving something with a little extra bite and a hearty, melty layer.
- → Can I prep the special sauce early?
Totally! Whip up the sauce and stash it in your fridge in a sealed jar. Let it chill for a few hours so all those tangy flavors have time to come together nicely.
- → Should I use frozen fries or cut my own?
Frozen fries are quick and crispy, but cutting fresh potatoes lets you make them just how you like—bake or fry until they're perfect for your taste.
- → How do I keep fries from turning soggy?
Make sure your fries are really crisp before adding toppings. Melt the cheese fast while they're hot, then toss on onions and sauce just as you serve for that crave-worthy crunch.
