Ingredients
  

Base Ingredients:

  • 10 large eggs
  • 1/2 cup heavy cream
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder

Protein & Vegetables:

  • 1 cup cooked bacon crumbled (or sausage, diced ham)
  • 1/2 cup bell peppers diced (any color)
  • 1/2 cup spinach chopped
  • 1/4 cup onion finely chopped
  • 1/2 cup mushrooms sliced (optional)

Cheese & Toppings:

  • 1 cup shredded cheddar cheese
  • 1/2 cup mozzarella cheese
  • 1/4 cup crumbled feta optional
  • 1 tablespoon chopped fresh parsley for garnish

Instructions
 

Step 1: Preheat the Oven

  • Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish with butter or cooking spray.

Step 2: Prepare the Egg Mixture

  • In a large mixing bowl, whisk together the eggs, heavy cream, salt, black pepper, garlic powder, and onion powder until well combined.

Step 3: Cook the Protein & Vegetables

  • If using bacon or sausage, cook it in a skillet over medium heat until fully cooked. Remove from the skillet and drain any excess grease. In the same skillet, sauté the bell peppers, onions, spinach, and mushrooms until softened.

Step 4: Assemble the Casserole

  • Spread the cooked protein and sautéed vegetables evenly in the greased baking dish. Sprinkle half of the shredded cheddar and mozzarella cheese over the top. Pour the egg mixture evenly over the ingredients, then sprinkle the remaining cheese on top.

Step 5: Bake

  • Place the dish in the preheated oven and bake for 30-35 minutes or until the eggs are set and the top is golden brown.

Step 6: Cool and Serve

  • Allow the casserole to cool for 5-10 minutes before slicing. Garnish with fresh parsley, then serve and enjoy!
