Instructions
 

  • Cook the Beef Base
  • Heat a large skillet over medium heat.
  • Add ground beef and cook until browned.
  • Add onion and garlic; sauté until soft.
  • Stir in smoked paprika, mustard, tomato paste, and pickle juice.
  • Season with salt and pepper.
  • Remove excess grease if needed—this keeps the casserole from becoming oily.
  • Prepare the Egg Mixture
  • In a bowl, whisk eggs, heavy cream, salt, pepper, and 1 cup cheddar.
  • This creates the creamy, custard-like layer that binds the entire casserole.
  • Assemble the Casserole
  • Preheat oven to 350°F (175°C).
  • Spread the beef mixture evenly into a greased baking dish.
  • Pour the egg mixture over the top.
  • Sprinkle more cheese across the surface.
  • Bake
  • Bake for 25–30 minutes, until set and lightly golden.
  • Add crisped bacon during the last 5 minutes for extra flavor.
  • Let the casserole cool for 10 minutes before slicing.
  • Optional Big Mac Style
  • Top with shredded lettuce, diced pickles, and keto-friendly Big Mac sauce after baking. It becomes the ultimate Keto Big Mac Casserole.
