Ingredients for in and out burger french fries
These 13 ingredients deliver the iconic In-N-Out experience—crispy, salty, golden fries that stay perfect.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 2 ½ lb | Large size, uniform shape for even frying |
| Vegetable Oil 🫒 | 4 cups | High smoke point, like peanut or canola |
| Coarse Kosher Salt 🧂 | ½ cup | Diamond Crystal preferred for texture |
| Ground Black Pepper 🌶️ | 1 tsp | Freshly cracked for bold flavor |
| Garlic Powder 🧄 | 1 tbsp | No garlic salt—pure powder |
| Onion Powder 🧅 | 1 tbsp | For that classic In-N-Out tang |
| Ground Cumin 🌿 | ½ tsp | Earthy depth, not missing |
| White Vinegar 🍶 | 1 tbsp | Brightens flavor after frying |
| Unsalted Butter 🧈 | 2 tbsp | For post-fry richness |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
| Ground Beef 🥩 | 1 lb | 80/20 fat ratio for juiciness |
| Sesame Seed Buns 🍞 | 4 whole | Toasted for authentic texture |
| Yellow Mustard 🟡 | ¼ cup | For classic In-N-Out pairing |
The potatoes are non-negotiable—Russets cut the mustard for their starch content. Grab the largest uniform size you can find; Costco or Trader Joe's usually stock them in bulk. Avoid anything green or misshapen. For the beef, 80/20 fat ratio is key—it keeps the patties juicy. If you can't find it, 85/15 works in a pinch, but expect slightly drier results. The sesame seed buns? Toast them lightly before serving to mimic the restaurant's approach, but don't overdo it or they'll burn.
No coarse kosher salt? Diamond Crystal is the gold standard, but Morton or any coarse salt will do—just shake it on generously. Short on vinegar? Lemon juice at half the amount adds brightness, though it won't be identical. The seasoning blend is where the magic happens—skip pre-made taco seasoning; garlic powder, onion powder, and cumin are the holy trinity for that animal-style tang. For the oil, peanut or canola both work, but avoid olive oil—it burns too easily. If you're feeling fancy, render your own beef fat for frying the patties, but vegetable oil is perfectly fine for the fries.
Potatoes keep 3-4 days in the fridge, wrapped in a damp towel. The seasoning mix stays potent for 6 months in an airtight container. For the patties, form them 1 hour before cooking and chill—they'll hold together better. Fries reheat beautifully in the oven at 400°F for 10 minutes, but they're best fresh. Double the batch; leftovers disappear fast. Store fries in a paper towel-lined container to maintain crispiness.

Step-by-step instructions for in-n-out burger French fries
Here's how to achieve that iconic In-N-Out crunch and flavor at home—every bite will be crispy, salty, and golden.
Cut and Soak the Potatoes for Perfect Texture
Start by peeling the 2.5 lb russet potatoes and cutting them into 1-inch thick sticks using a mandoline or sharp knife. I like to cut them slightly thicker than traditional fries—this ensures they stay crispy on the outside while remaining tender inside. Place the cut potatoes in a large bowl and cover completely with cold water. Let them soak for 30 minutes to remove excess starch, which prevents soggy fries later.
After soaking, drain the potatoes thoroughly and pat them completely dry with paper towels. This step is critical—any moisture left on the potatoes will steam instead of crisp when frying. Arrange them in a single layer on a baking sheet and let them air-dry for another 15 minutes. The drier they are, the crispier your fries will become.
Season and Double-Fry for Maximum Crispiness
Preheat 2 cups of the vegetable oil in a deep fryer or heavy pot to 325°F. While the oil heats, toss the dried potatoes with 0.5 cup coarse kosher salt, 1 tbsp garlic powder, 1 tbsp onion powder, and 0.5 tsp ground cumin in a large bowl until evenly coated. The salt should cling to every surface—this is what creates that signature In-N-Out flavor.
Working in batches to avoid overcrowding, carefully lower the potatoes into the hot oil using a slotted spoon. Fry for 4-5 minutes until they're soft but not browned. Remove them with a slotted spoon and drain on a wire rack or paper towels. Immediately increase the oil temperature to 375°F for the second fry. Once the oil reaches temperature, fry the potatoes again for 2-3 minutes until they're golden brown and crispy. This double-fry method is key to achieving that perfect In-N-Out texture.
Finish with Vinegar and Butter for Authentic Flavor
Transfer the crispy fries to a clean bowl and immediately drizzle with 1 tbsp white vinegar and 2 tbsp melted unsalted butter. Toss gently to coat evenly—the vinegar brightens the flavor while the butter adds richness. This step mimics the secret finishing technique used at In-N-Out, giving the fries that signature tangy kick.
Let the fries rest for 2-3 minutes while you prepare your toppings. The slight rest allows the flavors to meld together while keeping them crisp. Garnish with 0.25 cup chopped fresh parsley just before serving to add a touch of freshness that balances the bold seasoning.
Serve Immediately with Classic Pairings
Serve the fries immediately while they're at their peak crispiness. The secret to perfect In-N-Out fries is timing—they lose their crunch as they cool. For an authentic experience, pair them with 4 toasted sesame seed buns and 0.25 cup yellow mustard. The buttery buns and tangy mustard complement the salty, garlicky fries perfectly, just like the original.
I like to serve these with 1 lb of seasoned ground beef patties made with the remaining seasonings (garlic powder, onion powder, and cumin) for a complete In-N-Out experience. The combination of crispy fries, juicy beef, and toasted buns creates a meal that's impossible to resist. Enjoy them fresh out of the fryer for the ultimate taste of California's favorite fast food.
Pro Tips For Making In And Out Burger French Fries
- CUT POTATOES IN EVEN STRIPS: Use a mandoline or sharp knife to slice Russets exactly ¼-inch thick—no thicker, no thinner. I learned this the hard way when my first batch turned out uneven, and some pieces were soggy while others burned. A ruler helps keep your cuts consistent.
- DOUBLE-FRY WITH REST TIME: After the first fry at 325°F, drain well and let them rest 5 minutes before the second fry at 375°F. Skipping this rest means oil splatter and uneven crispiness—your future self will notice the difference.
- SALT THE OIL FIRST: Toss in a generous pinch of kosher salt directly into the hot oil before adding the potatoes. This seasons the exterior immediately and cuts down on post-fry tossing. (Yes, even if you’re impatient like me.)
- USE COLD POTATOES, NOT WARM: Soak sliced Russets in ice water for 30 minutes, then thoroughly dry them before frying. Cold potatoes fry faster and more evenly—no more greasy, limp fries. (I skip this when I’m lazy, but the dish is noticeably better when I don’t.)
Regional styles of this recipe
California Roots
The original In-N-Out Burger fries were born in Baldwin Park, California in 1948, where Harry Snyder and his wife Esther created a drive-in that became a West Coast legend. Their secret?
A double-fry technique using peanut oil (though vegetable oil works just as well) and a generous salt coating—a method that became the gold standard for fast-food fries nationwide.
The original recipe called for no butter finish, but modern versions (like the animal-style fries) now include it for extra richness. 🌶️
Animal-Style Evolution
In-N-Out’s animal-style fries—loaded with grilled onions, mustard, and butter—weren’t part of the original menu but became a cult favorite in the 1980s. The name comes from the animal crackers (a childhood snack) that inspired the toppings.
For authenticity, use yellow mustard (never sweet relish) and sliced raw onions grilled in butter until caramelized. The key is high heat—I grill onions in a cast-iron skillet over medium-high heat for 3-4 minutes until golden and jammy. ✨
Texas Twist
While In-N-Out is a California staple, Texas locations (like those in Houston and San Antonio) put their own spin on the fries by adding shredded cheese and jalapeños to the animal-style version.
Locals swear by Monterey Jack or cheddar melted over the hot fries, with pickled jalapeños for a tangy kick. To recreate this, sprinkle ½ cup shredded cheese on the fries right after the second fry, then broil for 1-2 minutes until bubbly. 🔥
Midwest Adaptations
In states like Ohio and Michigan, In-N-Out fries are often served with chili cheese fries—a nod to the region’s love of chili mac. The trick is to mix ½ cup chili (homemade or canned) with ¼ cup shredded cheddar, then spoon it over the hot fries.
Top with green onions and a dash of hot sauce for that Midwest kick. The chili adds a smoky depth that contrasts beautifully with the salty, garlicky fries. 💫
Healthier Takes
For a lighter but still crispy version, swap the double-fry for a single bake-and-air-fry hybrid. Toss 1-inch potato sticks with 1 tbsp olive oil, 1 tsp garlic powder, and ½ tsp salt, then bake at 425°F for 20 minutes.
Finish in an air fryer at 375°F for 5-7 minutes until golden. Skip the butter and use lemon juice instead of vinegar for brightness. This cuts calories by 40% but keeps the In-N-Out crunch. 💪

Frequently asked questions
Why do In-N-Out fries need a double-fry?
The double-fry method creates the perfect texture: first at 325°F for 4-5 minutes cooks the potatoes through, while the second fry at 375°F for 2-3 minutes crisps the exterior. This two-stage process mimics the restaurant's technique and prevents soggy centers while maximizing crunch.
Can I make these fries without a deep fryer?
Use a heavy pot with 2-3 inches of oil on the stove. A deep fryer thermometer is essential to monitor the 325°F and 375°F temperatures accurately. Never exceed 375°F—higher temps burn the fries before they crisp.
What's the secret to keeping fries crispy?
Drain fries on a wire rack (not paper towels) after each fry to remove excess oil. Serve immediately, and store leftovers in a paper towel-lined container at room temperature. Reheat in a 400°F oven for 5-7 minutes—never microwave, or they'll turn rubbery.
How do I make animal-style fries at home?
After the second fry, toss the hot fries with 2 tbsp melted butter and 1 tbsp yellow mustard. Top with grilled raw onions (sautéed in butter for 3-4 minutes until caramelized) and extra salt. The key is high heat for the onions—medium-high in a cast-iron skillet for that jammy texture.
Can I use frozen fries for this recipe?
Not for authenticity—they lack the double-fry texture and seasoning depth. If you're short on time, bake frozen fries at 425°F for 15 minutes, then toss with 1 tsp garlic powder, ½ tsp salt, and a splash of vinegar. They won't be identical, but it's a decent shortcut.
