Description

A hearty, low-carb breakfast casserole packed with fluffy eggs, cheese, and your choice of savory sausage or bacon—perfect for meal prep or a cozy brunch.


Ingredients

  • 10 large eggs
  • 1/2 cup heavy cream
  • 1 lb breakfast sausage or bacon, cooked and crumbled
  • 1 cup shredded cheese (cheddar, mozzarella, or a blend)
  • 1 cup baby spinach or chopped bell peppers
  • 1/2 medium onion, diced
  • 2 cloves garlic, minced
  • Salt and pepper to taste
  • Optional: 2 tbsp fresh herbs (parsley, chives, or thyme)


Instructions

  1. Preheat oven to 350°F (175°C). Grease an 8×8 or 9×13 baking dish.
  2. Cook sausage or bacon in a skillet over medium heat until browned. Drain excess fat, leaving 1 tbsp in the pan.
  3. Add diced onion, garlic, and spinach or bell peppers. Sauté until veggies are soft.
  4. In a large bowl, whisk together eggs, heavy cream, salt, pepper, and optional herbs.
  5. Spread cooked meat and veggies in the baking dish. Pour egg mixture over, then sprinkle with cheese.
  6. Bake for 30–35 minutes until eggs are set and top is golden. Let rest 5 minutes before slicing and serving.

Notes

  • Use a muffin tin for individual portions — great for freezing and meal prep.
  • For a dairy-free version, use coconut milk and plant-based cheese.
  • Top with avocado, salsa, or fresh herbs before serving for extra flavor.
