Ingredients

Servings4

Yields 12 muffins

  • (8) large eggs
  • (1/2 cups) milk
  • (1/2 teaspoons) salt
  • (1/4 teaspoons) black pepper
  • (1/2 cups) diced bell peppers (any color)
  • (1/2 cups) diced onion
  • (1/2 cups) chopped spinach
  • (1/2 cups) shredded cheese (cheddar or your choice)
  • (1/4 cups) diced tomatoes
  • (1 tablespoon) olive oil

Instructions

  1. 1

    Preheat your oven to 350°F (175 °C).

  2. 2

    In a large bowl, whisk together 8 large eggs, 1/2 cup milk, 1/2 teaspoon salt, and 1/4 teaspoon black pepper until well combined. Add 2/4 teaspoon salt.

  3. 3

    In a skillet, heat 1 tablespoon olive oil over medium heat. Add 1/2 cup diced bell peppers and 1/2 cup diced onion, sautéing until softened, about 5 minutes.

  4. 4

    Add 1/2 cup chopped spinach and 1/4 cup diced tomatoes to the skillet, cooking for an additional 2 minutes until the spinach wilts. Remove from heat and let cool slightly.

  5. 5

    In the egg mixture, stir in the sautéed vegetables and 1/2 cup shredded cheese until evenly distributed.

  6. 6

    Grease a muffin tin with cooking spray or oil. Pour the egg and vegetable mixture into each muffin cup, filling them about 3/4 full.

  7. 7

    Bake in the preheated oven for 20-25 minutes, or until the egg muffins are set and lightly golden on top.

  8. 8

    Remove from the oven and let cool in the pan for 5 minutes before transferring to a wire rack to cool completely.

  9. 9

    Store the muffins in an airtight container in the refrigerator for up to 5 days. Reheat in the microwave for 30-60 seconds before serving.
