Instructions
Making The In-N-Out Sauce
- Combine the mayo, ketchup, mustard, vinegar, sweet pickle relish, salt, and pepper in a mixing bowl.
- Whisk until smooth and well-integrated. Refrigerate for flavors to meld together.
Prepare The Vegetables
- Slice the tomato into one-quarter inch slices. Wash and separate lettuce leaves and hand tear them to fit the hamburger bun. Grill the onions on the flat top grill or skillet.
Make The Beef Patties
- Divide the ground beef into 2 ounce balls.
- Press between 2 pieces of parchment paper. Use a heavy spatula or a burger press to press the burgers.
- The diameter of the meat patty should be slightly larger than the bun.
Grill the Hamburger Buns
- Use a flat top grill or a skillet to grill the buns until golden brown.
Grilling The Beef Patties
- Heat flat-top or skillet to 350°F. Cook patties for 2-3 minutes and then flip them.
- Add cheese immediately after flipping.
- Add the top bun immediately after adding the cheese and optional onions.
Assembling The In-N-Out Burger
- Start with the bottom bun. Spread sauce completely over the bottom bun.
- Layer 2 thin tomato slices.
- Add 3-4 layers of crisp iceberg lettuce.
- Add the burger patty with cheese, optional onions and bun directly from the grill to the top of the lettuce.
- The assembly order is crucial. Please use the diagram to ensure you assemble your In-N-Out Burger correctly.
- Eat the burgers immediately after assembling them.

In-N-Out Expert Details
The secret to an authentic In-N-Out burger is in the details. If possible, use a flat-top grill, and never press down on the patties while cooking—this releases precious juices and dries out the meat. Only flip the burger once to ensure a nice crust. Add cheese immediately after you flip the patty and place the top bun on while the meat is still on the grill. The assembly order is crucial. Please use the diagram below to ensure you assemble the burger correctly.
A burger is just a burger if you only consider the ingredients. All burgers are made from basically the same ingredients: meat, cheese, bread, lettuce, tomato, onion, and some condiments. The difference is all about the proportions, the bread, how the meat is cooked, and how the burger is assembled. Let’s dive into this In-N-Out Burger recipe so you can make this iconic burger at home.
Substitutes
