Ingredients
- 1.5 lb (680g) 80/20 ground beef
- 4 slices bacon, chopped
- 1/2 medium yellow onion, finely diced
- 2 cloves garlic, minced
- 3 tbsp sugar-free tomato paste
- 2 tbsp yellow mustard
- 1 tbsp Worcestershire sauce
- 4 large eggs
- 3/4 cup (180ml) heavy cream
- 8 oz (225g) cream cheese, softened
- 2 cups (200g) shredded cheddar cheese, divided
- 2 dill pickle spears, finely chopped (plus more to serve)
Instructions
- 1
Preheat the oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.

In a large skillet over medium heat, cook the chopped bacon until crisp, then add the ground beef, onion, and garlic. Cook until the beef is browned and the onion is soft, about 8 minutes. Drain excess grease.

Stir the tomato paste, mustard, and Worcestershire sauce into the beef. Fold in the softened cream cheese until melted and creamy. Remove from heat and stir in the chopped pickles, then spread the mixture into the prepared dish and top with 1 cup of the cheddar.
- 4
In a bowl, whisk together the eggs, heavy cream, and remaining 1 cup cheddar with a pinch of salt and pepper. Pour evenly over the beef layer.

Bake for 30-35 minutes, until the top is golden and the center is set. Let rest 5 minutes, then slice and serve topped with extra chopped pickles.
Tips & notes
- Swap cheddar for a Mexican blend or pepper jack for a spicier casserole, or stir in a 4 oz can of diced green chiles with the beef.
- Store leftovers covered in the fridge for up to 4 days. Reheat individual portions in the microwave or warm the whole dish, covered, at 350°F until heated through.
- For extra burger flavor, drizzle servings with sugar-free ketchup and a little more mustard — both add negligible carbs.
