Keto In-N-Out Burger Recipe: Homemade Double-Double, Animal Style

Hey there, friends! Who doesn’t love sinking their teeth into a juicy In-N-Out burger? The pop of flavors, the indulgent experience—it’s no wonder In-N-Out has become a favorite fast food chain. But what if I told you that you can recreate that mouthwatering delight at home, all while staying true to your keto lifestyle? Today, I’ll be sharing my secret recipe for a homemade keto In-N-Out Burger, complete with double patties and animal-style goodness. Get ready to embark on a delicious culinary adventure with me!

Understanding the Keto Diet

Before we jump into the recipe, let’s quickly go over the basics of the ketogenic diet. The keto diet is a low-carb, high-fat, and moderate-protein way of eating that has gained popularity for its weight loss and health benefits. By minimizing carbohydrate intake and increasing fat consumption, our bodies enter a state of ketosis. This metabolic state allows us to burn fat for fuel, resulting in lasting energy and potential weight loss.

Recreating the In-N-Out Experience

Now, let’s talk about recreating that In-N-Out Burger experience in a keto-friendly way. The key to nailing this homemade masterpiece is finding suitable substitutes for the original components. Instead of traditional buns, we’ll opt for lettuce wraps or keto-friendly alternatives. Fresh, high-quality ingredients are crucial, allowing us to customize the burger to our liking. And one cannot forget the famous animal-style concept! Don’t worry, I’ve got some keto-approved modifications up my sleeve to satisfy those taste buds.


To bring this keto In-N-Out Burger to life, you’ll need the following ingredients:

  • Ground beef patties (90% lean, 10% fat)
  • Salt and pepper (to season the patties)
  • Lettuce leaves (for the bun replacement)
  • Cheddar cheese slices
  • Red onion (thinly sliced)
  • Tomatoes (sliced)
  • Dill pickles (sliced)
  • Mustard (sugar-free)
  • Mayonnaise (preferably homemade or sugar-free store-bought)
  • White vinegar
  • Onion powder
  • Garlic powder
  • Paprika
  • Yellow mustard
  • Worcestershire sauce
  • Sugar-free ketchup


Time to assemble our keto In-N-Out Burger masterpiece! Follow these easy steps:

  1. Preheat your grill or stovetop grill pan to medium-high heat.
  2. Season your ground beef patties with salt and pepper on both sides.
  3. Place the patties on the grill and cook for about 4-5 minutes per side, or until your desired level of doneness is reached.
  4. While the patties are cooking, let’s prepare the secret sauce. In a small bowl, combine mayonnaise, mustard, white vinegar, onion powder, garlic powder, paprika, and Worcestershire sauce. Mix well until you have a creamy, tangy sauce.
  5. Once the patties are cooked, top each patty with a slice of cheddar cheese and allow it to melt slightly.
  6. To create that animal-style magic, spread a generous amount of the secret sauce on each lettuce leaf.
  7. Next, layer on the red onion slices, tomato slices, and dill pickle slices.
  8. Place the cheesy patty on top of the veggies, and wrap it all up with another lettuce leaf.
  9. Repeat these steps to create your double-double keto In-N-Out Burger.
  10. Serve with a side of sugar-free ketchup and enjoy the indulgence!

Additional Tips and Variations

Want to take your keto In-N-Out Burger to the next level? Here are a few tips and variations to consider:

  • If you’re not a fan of lettuce wraps, try using almond flour buns or cloud bread as an alternative.
  • Experiment with different seasonings for your patties, such as garlic powder, onion powder, or even a hint of cayenne pepper for some gentle heat.
  • If grilling isn’t an option, you can easily cook the patties in a well-oiled skillet over medium-high heat.
  • Don’t be afraid to add more toppings or customize the recipe according to your preferences. Avocado slices, bacon, or even a fried egg can take your keto burger to new heights.


Friends, having a keto-friendly In-N-Out Burger recipe in your arsenal allows you to satisfy your fast food cravings without derailing your health goals. With a little effort and creativity, you can whip up an indulgent, low-carb burger that hits all the right spots. So, what are you waiting for?
