Ingredients
  

For the Casserole
  • 6 oz bacon diced (about 5 slices)
  • 1 cup onion finely chopped
  • 1 teaspoon minced garlic
  • 1 cup red bell pepper diced
  • 1 cup green bell pepper diced
  • 12 eggs beaten
  • ½ teaspoon sea salt
  • ¼ teaspoon pepper
  • 1 cup cheddar cheese shredded (4 oz)

Equipment

  • 9x13 inch baking dish
  • Large skillet
  • Medium bowl

Method
 

  1. Preheat your oven to 350 degrees F. Grease a 9x13 inch baking dish and set it aside.
  2. In a large skillet over medium heat, cook the diced bacon until it just starts to soften.
  3. Add the minced garlic and chopped onion to the skillet with the bacon and cook until the bacon begins to brown.
  4. Add the diced red and green bell peppers. Cover the skillet and cook for 5-10 minutes, or until the vegetables are soft and the bacon is browned, stirring occasionally.
  5. Remove the skillet from the heat and let the mixture cool.
  6. In a medium bowl, whisk the beaten eggs.
  7. Add the sea salt and pepper to the eggs and whisk to combine.
  8. Stir the cooled bacon and vegetable mixture into the beaten eggs.
  9. Add the shredded cheddar cheese and stir to combine.
  10. Pour the egg mixture into the prepared baking dish and spread it evenly.
  11. Bake in the preheated oven for 25-30 minutes, or until the top is set and slightly browned.
  12. Let the casserole cool for 5 minutes before serving warm.

Notes

You can substitute thick-cut bacon, turkey bacon (add 1 tbsp olive oil when cooking veggies), or crumbled breakfast sausage. Any type of onion works well. You can use any color of bell peppers or substitute 2 cups of your favorite vegetables. Extra sharp cheddar is recommended, but Colby jack, Swiss, pepper jack, or mozzarella also work well. To make this vegetarian, omit the bacon and use 2 tablespoons of olive oil to sauté the vegetables. Cut the casserole into squares and store in an airtight container in the refrigerator for up to 5 days. To freeze, cool completely, cut into serving sizes, and freeze in an airtight container for up to 2 months. Reheat in the microwave or oven until heated through.
