Description

A nutritious and flavorful Healthy Breakfast Casserole featuring sautéed bell peppers, green onions, spinach, and creamy feta cheese baked with eggs and your choice of dairy. Perfect for meal prep or a wholesome start to your day.


Ingredients

Scale

Vegetables and Aromatics

  • 2 medium red bell peppers, chopped (about 2 cups)
  • ¾ cup thinly sliced green onion (about 1 small bunch)
  • 5 ounces roughly chopped spinach (about 5 cups)

Egg Mixture

  • 12 eggs
  • 3 tablespoons full-fat dairy (heavy cream, half-and-half, whole milk, sour cream or yogurt)
  • Several dashes of your favorite hot sauce, like Cholula
  • ½ teaspoon fine salt
  • 10 twists of freshly ground black pepper

Other

  • 1 tablespoon extra-virgin olive oil
  • 4 ounces (1 cup) crumbled feta or goat cheese, divided
  • Butter for greasing the pan


Instructions

  1. Preheat and Prepare Pan: Preheat the oven to 350 degrees Fahrenheit. Grease a 9 by 13-inch baking pan generously with butter for best results.
  2. Sauté Vegetables: In a large skillet, warm the olive oil over medium heat until shimmering. Add the chopped red bell pepper and sliced green onion, cooking for about 8 to 10 minutes until the peppers are tender and cooked through.
  3. Cook Spinach: Add the spinach to the skillet and stir while cooking until wilted, about 2 minutes. Remove the skillet from heat and set aside to cool slightly.
  4. Mix Eggs and Dairy: Crack the eggs into a medium mixing bowl. Add the chosen dairy (heavy cream, half-and-half, whole milk, sour cream, or yogurt), hot sauce, salt, and black pepper. Whisk just until the yolks and whites are blended together.
  5. Combine Cheese and Vegetables: Stir in half of the crumbled cheese to the egg mixture. Then, transfer the cooled vegetables into the bowl and gently stir to combine all ingredients evenly.
  6. Assemble Casserole: Pour the combined mixture into the prepared baking pan. Evenly sprinkle the remaining cheese on top of the mixture.
  7. Bake: Bake the casserole in the preheated oven for 35 minutes. Check that the eggs are puffed, cooked through, and that the center jiggles only slightly when shaken. Insert a fork about ¼-inch into the center; it should come out clean when fully cooked.
  8. Cool and Serve: Remove the casserole from the oven and place it on a cooling rack until ready to serve. Slice with a sharp knife and serve warm. Store leftovers in the refrigerator for up to four days.

Notes

  • Prepare in advance: You can mix and refrigerate the egg and vegetable mixture up to two days before baking. When baking from cold, add a few extra minutes to the bake time.
  • Vegetable substitutions: Feel free to swap in other vegetables such as kale, chard, or mushrooms. Hardier greens may need slightly longer cooking time.
  • Freezing not recommended: This casserole does not freeze well; leftovers become watery and rubbery. Consider egg-based breakfast burritos as a freezer-friendly alternative.
  • Serving suggestions: This casserole can be enjoyed chilled, at room temperature, or gently reheated in the microwave or oven.
