Ingredients

Scale
  • 1 1/2 pounds ground beef (80/20 preferred, but leaner works)
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon smoked paprika
  • 1 small yellow onion, diced (about 1/2 cup; optional)
  • 2 cloves garlic, minced
  • 4 large eggs
  • 3/4 cup heavy cream (or half-and-half for lighter option)
  • 1 teaspoon yellow mustard
  • 2 tablespoons tomato paste (or no-sugar ketchup)
  • 2 cups shredded cheddar cheese
  • 8 slices bacon, cooked and chopped
  • 1/4 cup chopped dill pickles (optional)
  • 2 tablespoons chopped green onions

Instructions

  1. Preheat oven to 375°F (190°C). Grease a 9×13 inch baking dish with butter or nonstick spray.
  2. In a large skillet over medium heat, cook bacon until crispy (about 8–10 minutes). Transfer to a paper towel-lined plate and crumble when cool. Reserve 1–2 tablespoons bacon fat in the skillet if desired.
  3. Add ground beef to the skillet. Cook, breaking up with a spatula, until browned (5–7 minutes). Add diced onion (if using) and minced garlic; sauté 2–3 minutes until fragrant and soft. Season with salt, pepper, and smoked paprika. Drain excess fat, leaving about 1 tablespoon for flavor.
  4. Spread the cooked beef mixture evenly in the prepared baking dish.
  5. In a medium bowl, whisk together eggs, heavy cream, mustard, and tomato paste until smooth and pale yellow.
  6. Pour the egg mixture evenly over the beef in the baking dish. Use a spatula to gently spread if needed.
  7. Sprinkle shredded cheddar cheese over the top, then scatter the cooked, crumbled bacon evenly.
  8. Bake in the center of the oven for 20–25 minutes, or until the cheese is melted, bubbly, and just starting to brown. The center should be just set (it’ll jiggle slightly but firm up as it cools). Tent with foil if cheese browns too quickly.
  9. Let the casserole cool for 5 minutes. Sprinkle with chopped dill pickles and green onions.
  10. Slice into squares and serve warm. Optional: garnish with sugar-free ketchup or mustard.

Notes

For best results, don’t overbake—the casserole should be just set in the center. Use freshly shredded cheese for better melting. Customize with extra veggies, different cheeses, or ground turkey/chicken. Let cool before slicing for neat portions. Can be made ahead and reheated; leftovers freeze well.
