Keto Burger – In-N-Out Style

This Keto Burger is made to resemble an Animal Style Double Double Cheeseburger from In-N-Out. It’s gluten-free, low-carb, and super tasty either as a bunless burger or with a Keto friendly bun.

Obviously you don’t need a recipe for a simple Keto Burger but today we’re sharing this In-N-Out copycat recipe that we think you’re going to LOVE! I mean, who doesn’t love In-N-Out?

Here are the benefits of making your own In-N-Out Keto Burger at home versus option for a fast food burger:

• low-carb – there’s only about 3 net carbs in this Keto Burger
• quality ingredients – you have complete control to choose higher quality ingredients like grass-fed beef, unprocessed American cheese and organic veggies and fats if that’s your thing

What’s in an In-N-Out style Keto Burger recipe?

• butter grilled onions
• two mustard grilled burger patties
• one slice of American cheese
• fry sauce
• pickles
• tomato

How to make an In-N-Out Keto Burger at home

1. First, you’ll start by portioning out 4 (2-oz) ground beef patties. We opt for 85-15 beef. Flatten them out until they are about the width of your fist. Season with salt and pepper.
2. Heat the butter in a cast-iron skillet over medium heat. Once melted, lower the heat the low add in the diced onions and allow to cook until dark golden brown, about 10 minutes. Stir occasionally but use this time to assemble the remaining ingredients.
3. For the fry sauce, simply mix all of the ingredients together in a small bowl or jar and refrigerate until ready to use.
4. Once the onions are done, remove them to a plate and set aside.
5. Increase the heat to medium and place the burgers in the skillet. Cook 2-3 minutes per side. Once you flip, brush the tops of each burger with a teaspoon of yellow mustard. Flip then place a slice of cheese on top of two of the burgers. Cover the skillet and cook for the 2-3 minutes while the cheese is melting.
6. Assemble the Keto Burgers – if using a bun simply stack from the bottom up…tomato, pickle, a patty with cheese on top, the other patty, fry sauce, onions. If using lettuce simply do the same order and wrap in lettuce.

What is fry sauce?

Fry sauce is a condiment often served with French fries. It is usually a combo of one part tomato ketchup and two parts mayonnaise. We’re upping the mayo a bit for some extra fat and using sugar-free ketchup to make this Keto friendly. Our favorite sugar-free Keto ketchup is Primal Kitchen. It tastes like fancy style ketchup, it’s good! We also use Primal Kitchen avocado oil mayonnaise.

To make this In-N-Out style fry sauce we also added in a few teaspoons of minced dill pickles, vinegar, and a Keto sweetener, we used powdered erythritol.

Where to find unprocessed American style cheese?

We were STOKED to see two options in our local grocery store lately. One is from Organic Valley and Horizon Organics. Applegate also has an American style cheese and there are a few other brands floating around out there that make quality, ACTUAL cheese, American Singles.

Keto Burger bun options

For this recipe, you can use a bun or lettuce as pictured. If you choose to go the bun route, here are a few of our favorite buns for low-carb burgers and a recipe that turns out perfect every time.

Store-bought options:

UnBun – we purchase these buns at Whole Foods, they resemble the buns from Diet Doctor that we link to below

Smartbun – we haven’t tried these but a few of you have recommended them to us

Sola – we haven’t tried these as they are not gluten-free but if you’re not celiac or gluten intolerant then these may work for you!

Recipes:

We love this recipe from Diet Doctor! It’s simple and they come out perfect every time.
