A quick and easy keto-friendly casserole that layers seasoned ground beef, cheese, and eggs for a comforting, low-carb dinner without the bun.

Ingredients

Scale
  • 1 pound (450g) ground beef (80/20 blend, preferably grass-fed)
  • 4 large eggs, room temperature
  • 1 ½ cups (about 170g) shredded cheddar cheese
  • ½ cup finely chopped onion (about 1 small onion)
  • 2 cloves garlic, minced
  • ¼ cup (about 30g) almond flour
  • 1 tablespoon Dijon mustard
  • 1 teaspoon Worcestershire sauce
  • Salt and freshly cracked black pepper, to taste
  • 1 teaspoon dried Italian herbs (optional)
  • 1 tablespoon butter or olive oil for sautéing

Instructions

  1. Preheat your oven to 350°F (175°C). Position the rack in the middle for even baking.
  2. Heat 1 tablespoon of butter or olive oil in a large skillet over medium heat. Add chopped onions and cook for 3-4 minutes until translucent.
  3. Add minced garlic and cook for 30 seconds until fragrant, being careful not to burn it.
  4. Add ground beef to the skillet, break it up with a spatula, and cook until no longer pink, about 6-8 minutes. Drain excess fat if desired, leaving a bit for flavor.
  5. Season the beef with salt, pepper, dried Italian herbs, Worcestershire sauce, and Dijon mustard. Stir well and remove from heat. Let cool for about 5 minutes.
  6. In a medium bowl, whisk together eggs and almond flour until smooth. Stir in shredded cheddar cheese.
  7. Add the cooled beef mixture to the egg mixture and stir until evenly combined.
  8. Pour the mixture into a prepared 8×8 inch (20×20 cm) casserole dish and spread evenly to about 1.5 inches thick.
  9. Bake for 25-30 minutes until the top is golden brown and the center is set but slightly jiggly. A toothpick inserted should come out mostly clean.
  10. Let the casserole rest for 5-10 minutes before slicing and serving.

Notes

If cheese browns too quickly, cover loosely with foil halfway through baking. Avoid overbaking to keep the casserole moist; a slight jiggle in the center indicates doneness. Let beef mixture cool before mixing with eggs to prevent scrambling. For a melty cheese topping, add extra cheddar 5 minutes before end and broil briefly.
