Ingredients
  

  • 6 large eggs
  • 1 cup whole milk
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon paprika optional
  • 1 cup cooked crumbled breakfast sausage
  • 1/2 cup diced bell peppers
  • 1/2 cup diced onion
  • 1 cup shredded hash browns optional
  • 1 1/2 cups shredded cheddar cheese
  • 1/2 cup shredded mozzarella cheese optional
  • 1/4 cup grated Parmesan cheese optional
  • 2 to 3 sliced green onions
  • 1/2 cup chopped fresh spinach or kale

Method
 

  1. Preheat the oven to 350°F (175°C). Grease a 9-by-13-inch baking dish.
  2. Cook the onion and bell peppers in a lightly oiled skillet for 3 to 4 minutes. If using raw sausage, brown it fully and drain before adding it to the casserole.
  3. Whisk the eggs, milk, salt, pepper, and optional paprika in a large bowl.
  4. Stir in the cooked sausage, vegetables, hash browns, and greens. Fold in the cheddar, mozzarella, and Parmesan, reserving a little cheese for the top.
  5. Pour into the prepared dish and sprinkle with the reserved cheese.
  6. Bake for 40 to 45 minutes, until the center is set and a knife inserted near the middle comes out clean.
  7. Rest for 5 to 10 minutes, then top with sliced green onions and serve.
