This Keto Smash Burger delivers the ultimate restaurant-quality experience with crispy, lacy edges and a custom beef blend. Because you use a mix of chuck, brisket, and sirloin, every bite remains incredibly juicy and flavorful without the need for high-carb fillers.

Ingredients & What You’ll Need
Gather these high-quality cuts and low-carb essentials to create a burger that rivals any professional kitchen.
- Chuck beef: Provides the necessary fat content to ensure a juicy and tender patty.
- Brisket beef: Adds a distinct, smoky depth of flavor to the meat blend.
- Sirloin beef: Offers a lean and beefy component to balance the richer fats.
- Salt and pepper: Season the meat perfectly to highlight the natural beef flavors.
- American cheese: Melts effortlessly into the crevices of the smashed patty for a classic finish.
- Keto-friendly hamburger buns: Serve as a sturdy, low-carb base made from ingredients like almond or coconut flour.
- Nonstick spray: Prevents the beef from sticking to the cast-iron surface.
- Parchment paper: Acts as a barrier so the meat does not stick to your spatula or press while smashing.
- Optional toppings: Include fresh lettuce, pickles, and red onion to provide a refreshing crunch.
How to Make Keto Smash Burgers
This method focuses on a high-heat sear and a specific grinding technique to achieve the perfect texture.
1. Grind the Beef Blend
First, cut the chuck, brisket, and sirloin into small squares. You should feed these pieces into a meat grinder by alternating the different cuts to ensure an even distribution of fat. Next, portion the ground meat into balls. You must roll each portion loosely because over-compressing the meat can lead to a tough burger.
2. Sear and Smash the Patties
Heat a heavy cast-iron pan over medium-high heat and apply a light coat of nonstick spray. Place a meatball in the hot skillet and let it rest untouched for nearly a minute. Subsequently, place a sheet of parchment paper over the meat and smash it flat using a sturdy spatula or burger press. Sprinkle salt and pepper over the patty immediately after smashing.
3. Melt and Assemble
Cook the burger for two to three minutes until the bottom is deeply browned and the edges are crispy. Flip the patty and add a slice of American cheese. Furthermore, add a teaspoon of water to the pan and cover it quickly to trap the steam. This ensures the cheese melts perfectly over the meat. Finally, place the patty on a keto bun with your favorite toppings and enjoy. Therefore, you can have a gourmet keto meal ready in minutes.
Tips and Notes
- Meat Storage: Store extra meatballs in freezer bags to make a quick meal on busy weeknights.
- Reheating: Reheat your cooked patties in a hot skillet for 1-2 minutes to maintain the crispy edges.
- Yield: This recipe makes four single-patty burgers or two hearty double-patty burgers.
- Steam Method: Using a lid and a splash of water is the most efficient way to melt cheese without overcooking the beef.
