Equipment

  • Cast-iron skillet or griddle
  • Sturdy, heavy metal spatula
  • Parchment paper
  • Large plate or baking sheet
  • Cutting board
  • Knife

Ingredients
  

  • 1 lb 80/20 ground chuck
  • 1 tbsp avocado oil or beef tallow
  • 4 slices high-quality American cheese
  • ½ tsp Kosher salt
  • ¼ tsp coarse black pepper
  • ½ small yellow onion, thinly sliced
  • 8 large, crisp iceberg or romaine lettuce leaves for wrapping
  • ½ cup dill pickle chips
  • 1 medium tomato, sliced
  • ¼ cup keto-friendly burger sauce

Instructions
 

  • Gently divide the ground beef into 4 equal portions (4 oz each) and loosely roll them into balls. Do not overwork the meat. Place them on a parchment-lined plate and refrigerate until ready to cook.
  • Prepare all your toppings: wash and dry lettuce, slice tomato and onion, and have your cheese, pickles, and sauce ready.
  • Place a cast-iron skillet or griddle over medium-high to high heat and let it preheat for 5-7 minutes until it is extremely hot. Add a thin layer of oil just before cooking.
  • Place one or two beef balls onto the hot surface. Immediately use a sturdy spatula to press down firmly until the patty is about ¼ inch thick. Hold for 10 seconds to create a flat surface. Season the top generously with salt and pepper.
  • Cook for 60-90 seconds, until the edges are brown and crispy. Use the spatula to scrape cleanly under the patty, ensuring you lift the entire crust, and flip it over.
  • Immediately place a slice of cheese on top of the flipped patty. Cook for another 30-60 seconds until the cheese is perfectly melted.
  • Remove the patty from the skillet. Assemble your burger by placing one or two patties on a lettuce leaf, then top with sliced onion, tomato, pickles, and a drizzle of keto-friendly sauce.

Notes

Key Tips for Success:
- Do NOT use lean beef. 80/20 ground chuck is essential for a juicy burger with crispy edges.
- Ensure your pan is screaming hot before the beef touches it to achieve the perfect Maillard reaction and crust.
- Handle the beef gently. Form loose balls and do not overwork the meat to avoid a tough, dense burger.
Variations & Swaps:
- Cheese: Provolone, mild cheddar, pepper jack, or Swiss are great alternatives to American cheese.
- Bun Alternatives: Serve on keto-friendly buns, grilled portobello mushroom caps, or between two slices of grilled halloumi.
- Gourmet Additions: Sauté mushrooms and garlic for a Mushroom Swiss burger, or press thin jalapeño slices into the patty after smashing for a spicy kick.
