Ingredients

Egg Mixture

  • 8 large eggs
  • 1 cup heavy cream
  • 1 teaspoon garlic powder
  • Salt and pepper to taste

Vegetables and Cheese

  • 2 cups fresh spinach, chopped
  • 1/2 cup diced bell peppers
  • 1/4 cup diced onion
  • 1 cup shredded cheese (cheddar or mozzarella)

Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (175°C) to ensure it's ready for the casserole mixture.
  2. Prepare Egg Mixture: In a large mixing bowl, whisk together the eggs, heavy cream, garlic powder, salt, and pepper until fully combined and slightly frothy.
  3. Add Vegetables and Cheese: Stir in the chopped spinach, diced bell peppers, onion, and shredded cheese gently until evenly distributed throughout the egg mixture.
  4. Transfer to Baking Dish: Pour the entire mixture into a greased 9×13-inch baking dish, spreading it out evenly.
  5. Bake the Casserole: Place the baking dish in the oven and bake for 30-35 minutes, or until the eggs are fully set and the top is golden brown.
  6. Cool and Serve: Allow the casserole to cool slightly for easier slicing. Serve warm as a hearty breakfast or brunch option.

Notes

  • You can substitute heavy cream with full-fat coconut milk for a dairy-free version.
  • Add cooked sausage or bacon for added protein if desired.
  • Use any cheese you prefer; mozzarella gives a milder taste, cheddar adds sharpness.
  • Keep leftovers refrigerated and consume within 3-4 days.
  • To reheat, warm slices gently in the microwave or oven.
