What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and the fresh elements add that perfect homemade touch.

• For the Fries:
  • Russet potatoes – about 4 large (choose firm, starchy potatoes for best crispiness)
  • Vegetable or canola oil – for frying (I prefer canola oil for its neutral flavor)
  • Salt – to taste (sea salt or kosher salt works great)
• For the Grilled Onions:
  • Yellow onion – 1 large, thinly sliced
  • Butter – 2 tablespoons, unsalted (adds richness)
  • Salt and pepper – to taste
• For the “Animal Style” Sauce:
  • Mayonnaise – ½ cup (I recommend Hellmann’s or Duke’s for creaminess)
  • Ketchup – 3 tablespoons
  • Dill pickle relish – 2 tablespoons (adds that signature tang)
  • Yellow mustard – 1 teaspoon
  • White vinegar – 1 teaspoon (brightens the sauce)
  • Garlic powder – ½ teaspoon
  • Onion powder – ½ teaspoon
• For the Cheese:
  • American cheese – 4 slices (classic melty goodness; cheddar works too)

Feel free to swap out mayo for a vegan version or use gluten-free relish if needed. In summer, fresh pickles add even more crunch and brightness. The key here is fresh, simple ingredients that come together to make a memorable snack or side.

Equipment Needed

• Large heavy-bottomed pot or deep fryer – for frying the potatoes. I use a 6-quart Dutch oven, which holds heat well and prevents oil temperature drops.
• Thermometer – essential for keeping oil at the right temperature (around 325°F / 165°C for first fry, 375°F / 190°C for second fry).
• Slotted spoon or spider strainer – to safely remove fries from hot oil.
• Cast iron or non-stick skillet – perfect for sautéing the onions evenly.
• Mixing bowls – for tossing fries and mixing sauce.
• Paper towels or cooling rack – to drain excess oil from fries.

If you don’t have a thermometer, a quick oil test is dropping a small piece of potato in oil—if it bubbles vigorously but not smokes, you’re close. For budget options, a heavy pot and instant-read thermometer do the job well without fancy gadgets. I’ve tried air frying, but honestly, traditional frying wins for that authentic crisp.

Preparation Method

1. Prep the Potatoes: Peel the russet potatoes if you want (I usually leave the skin on for extra texture), then cut into ¼-inch thick fries. Rinse them in cold water to remove excess starch, then soak for at least 30 minutes (up to 2 hours) to get them extra crispy. Drain and pat completely dry with paper towels.
2. Make the Animal Style Sauce: While the potatoes soak, whisk together mayonnaise, ketchup, dill pickle relish, yellow mustard, white vinegar, garlic powder, and onion powder in a bowl. Taste and adjust seasoning if needed. Cover and refrigerate until serving.
3. Grill the Onions: Heat butter over medium heat in a skillet. Add thinly sliced onions, season with salt and pepper, and sauté gently for about 10-15 minutes or until golden brown and soft. Stir occasionally to avoid burning. Remove from heat and set aside.
4. Fry the Potatoes – First Fry: Heat oil in your pot or fryer to 325°F (165°C). Fry the dried potato sticks in batches for about 4-5 minutes until tender but not browned. Remove with slotted spoon and drain on paper towels. Let them cool for 10-15 minutes.
5. Fry the Potatoes – Second Fry: Increase oil temperature to 375°F (190°C). Fry the potatoes again in batches for 2-3 minutes until golden brown and crispy. Drain well and season immediately with salt.
6. Assemble the Fries: Place fries on a serving plate, layer with a generous amount of grilled onions, then cover with slices of American cheese. If you want gooey cheese, pop them under a broiler for 1-2 minutes or microwave for 30 seconds until melted.
7. Top with Animal Style Sauce: Drizzle or dollop the prepared sauce generously over the cheesy, onion-laden fries. Serve hot and enjoy immediately for the best experience.

Pro tip: Double-frying is worth the extra step—if you skip it, fries tend to be soggy, and that’s just no fun. Also, make sure your onions are soft and sweet, not burnt, to get that perfect balance. I sometimes prep the sauce a day ahead to let flavors marry—trust me, it makes a difference.

Cooking Tips & Techniques

Getting the perfect Crispy In-N-Out Animal Style Fries at home takes a little finesse, but I’ve learned a few things over the years that make it easier:

• Control Your Oil Temperature: Keeping a consistent oil temperature is key. Too hot and fries burn; too cool and they get greasy. Using a thermometer helps, but if you don’t have one, adjust heat carefully and fry in small batches.
• Dry Those Fries Thoroughly: After soaking, make sure fries are completely dry. Water on the surface causes oil splatter and soggy fries.
• Don’t Crowd the Pan: Frying in batches ensures fries cook evenly and stay crispy. Crowding drops the oil temperature and leads to limp fries.
• Slow-Cook Onions: Grilling onions low and slow brings out their natural sweetness—burnt onions will ruin the flavor.
• Use Quality Cheese: American cheese melts perfectly for this recipe, creating that iconic gooey layer. Avoid pre-shredded cheese, which contains anti-caking agents that affect melting.

I once tried skipping the double fry to save time—and the fries came out limp and disappointing. Lesson learned! Also, multitasking by prepping your sauce and onions while fries soak cuts down overall time. Finally, serve immediately for best texture; leftovers can get soggy fast.

Variations & Adaptations

This recipe is pretty flexible, so you can tweak it to suit your needs or cravings:

• Vegan Version: Use vegan mayo and cheese alternatives, swap butter for olive oil when grilling onions.
• Healthier Option: Bake the fries at 425°F (220°C) for 25-30 minutes tossing halfway or air fry at 400°F (200°C) for 15-20 minutes, then assemble as usual.
• Spicy Twist: Mix a little sriracha or chipotle powder into the animal sauce for a kick.
• Different Cheese: Try sharp cheddar or pepper jack for extra flavor variation; just note melting times might vary.
• Allergy-Friendly: Swap out mayo for avocado-based spread and pick gluten-free relish to avoid common allergens.

One personal favorite is adding a sprinkle of crispy bacon bits on top for extra crunch and smoky flavor—dangerously addictive! Also, swapping yellow onions for sweet Vidalia onions changes the sweetness profile subtly.

Serving & Storage Suggestions

Serve these Crispy In-N-Out Animal Style Fries piping hot for maximum crunch and melty goodness. They pair beautifully with a classic burger, a cold soda, or even a creamy milkshake for that true California fast-food vibe.

Leftovers? Store in an airtight container in the refrigerator for up to 2 days. To reheat, spread fries on a baking sheet and pop in a 400°F (200°C) oven for 5-7 minutes to crisp up again. The sauce is best added fresh, so keep it separate if you plan to store.

Over time, the flavors meld nicely if you prepare the sauce a day ahead, but fries are always best eaten fresh. If you’re making for a crowd, assemble just before serving to keep that irresistible crunch.
