I swear, their protein burgers got me through my pregnancy with gestational diabetes.  Absolute lifesavers!

But now I developed a love for protein style burgers so much I decided to experiment and make my own.

Now, of course, I had to put my own spin on things. What I ended up creating is a burger I am so happy with!

This keto protein style smash burger is incredibly delicious and filling.

Two thin beef patties, caramelized onions, and a creamy spicy garlic mayo spread are all sandwiched between two fresh lettuce buns.  It’s also fully customizable so you can add any of your favorite mix-ins!

What is a keto smash burger?

This keto smash burger contains 80/20 fat ratio ground beef that is smashed down on a frying pan to create a thin patty that is juicy on the inside and perfectly crispy and charred on the outside.

It’s topped with paper thin slices of onions and cooked until golden brown and caramelized.

Brushed with a creamy spicy garlic mayo spread and sandwiched between two crispy fresh lettuce buns to create a perfect restaurant style keto protein burger.

What kind of lettuce should I use for the protein burger lettuce wrap?

We like to use green leaf lettuce but if you prefer a more crunchy green, you can choose iceberg lettuce as well.

What’s kewpie and how is it different than American mayonnaise?

Kewpie mayo is Japanese mayonnaise. Compared to American mayonnaise, it is richer with a hint of sweetness.

  • Cooking Time 5M
  • Total Time 10M
  • Net Carb/Serv ~3g
  • Servings 2

Ingredients

Hamburgers

Patty

  • 1 lb Ground Beef (use at least 20% fat or greater)
  • 1/4 Cup Sliced Onions (about 1/4 of a medium onion)
  • 1/2 tsp Salt
  • 1/4 tsp Black Pepper
  • 4 Leaves Green Lettuce
  • 2 Slices American Cheese (optional)

Sauce

  • 3 tbsp Kewpie Mayo (you can sub with American mayo but will alter taste)
  • 1/2 tsp Sriracha
  • 1 Garlic Clove

Directions

1) Gather all the ingredients.

2) Thinly slice onions with a knife or slicer.

3) Grate garlic with a grater.

4) In a small mixing bowl, combine Kewpie Mayo, Sriracha, grated garlic, and set aside.

5) Take about 1/4 lbs of the ground beef and roll it into 2-3 inch diameter meatballs.  Repeat until you end up with 4 meatballs.

6) Bring a large Teflon frying pan up to temp on medium high heat (~1 minute) and place meatballs inside.  Use a spatula to press down on the meatballs to form a patty until they are around 1/2 inch thick.  Note – you may need to spray cooking oil depending on the pan.

7) Place the sliced onions on top of the patties followed by sprinkling salt and black pepper.  Cook for 2-3 minutes and then flip with the onions going on the bottom as shown below.  Cook for 2-3 more minutes until patties are browned or an internal temp of 160F is attained.

8) Take a lettuce leaf and place it onto a serving plate.  Next, add a beef patty with onion up, followed by optional cheese, beef patty onion side down, a generous spread of spicy mayo, other optional toppings and finally another piece of lettuce on top.  Use the lettuce to form a wrap and enjoy!  Note – a toothpick in the middle will help hold everything together.
