How to Make Keto Big Mac Smash Burgers

Now that we have our ingredients ready, let’s dive into the step-by-step instructions. I’ll guide you through each cozy moment of the cooking process:

  1. Start by forming the ground beef into equal-sized patties. Aim for about 1/3 pound each, so they’re substantial and filling.

  2. Preheat a skillet over medium-high heat; you want it nice and hot for those perfect smash marks!

  3. Once the skillet is ready, place the patties on it. Smash each one down with a spatula to ensure they get that delicious crust. Cook until browned on one side, then flip them over.

  4. In the last minute of cooking, lay a slice of Cheddar cheese atop each patty. Allow it to melt deliciously while the burger finishes cooking.

  5. Now it’s time to assemble! Using lettuce leaves as your bun, stack your melted cheeseburger with pickles, onions, sugar-free ketchup, mustard, and mayonnaise. Feel free to get creative!

  6. Serve immediately and enjoy these scrumptious keto-friendly Big Mac burgers with your family!

Fun Ways to Customize It

While the classic version is wonderful on its own, here are some fun variations that you can try:

  • Spicy Twist: Add a drizzle of hot sauce or jalapeños for an extra kick!
  • Herbaceous Delight: Mix chopped herbs like parsley or chives into your ground beef for a fresh flavor.
  • Creamy Avocado: Layer slices of rich avocado on your burger for added creaminess and nutrients.
  • Crunchy Coleslaw: Add a crunchy, zesty slaw to your burger for a beautiful texture contrast.
