Ingredients

  • ½ teaspoon olive oil
  • ½ cup bell pepper, diced (about ½ medium bell pepper, any color)
  • 1 cup fresh spinach, roughly chopped
  • ½ cup cherry or grape tomatoes, halved
  • 1 cup egg whites (or whites from 8 large eggs)
  • ⅓ cup shredded cheddar cheese
  • ¼ teaspoon black pepper
  • ¼ teaspoon garlic powder
  • ¼ teaspoon sea salt (optional, to taste)

Instructions

1️⃣ Preheat Oven

  • Set your oven to 400°F (200°C).

2️⃣ Sauté the Vegetables

  • Heat olive oil in an oven-safe 8-inch nonstick skillet over medium heat.
  • Add the diced bell pepper and cook for 4-5 minutes until softened.
  • Stir in the chopped spinach and cook for another 2 minutes until wilted.
  • Add the halved cherry tomatoes and cook for 1 more minute.
  • Pat the vegetables dry with a paper towel to remove excess moisture.

3️⃣ Prepare the Egg Mixture

  • In a medium bowl, whisk together the egg whites, black pepper, and garlic powder until foamy.

4️⃣ Combine & Cook

  • Pour the egg mixture over the sautéed vegetables in the skillet.
  • Sprinkle the shredded cheddar cheese evenly on top.
  • Let it cook on the stovetop for 1 minute until the edges start to set.

5️⃣ Bake

  • Transfer the skillet to the oven and bake for 16-20 minutes, or until the egg whites are fully cooked and the cheese is melted & bubbly.

6️⃣ Serve & Enjoy

  • Remove from the oven and let it cool slightly before slicing.
  • Optionally, garnish with sliced avocado and green onions.

Notes

  • Storage: Allow the frittata to cool completely, then store in an airtight container in the fridge for up to 2 days.
  • Reheating:
    • Microwave: Heat individual slices for 1-2 minutes.
    • Oven: Warm at 350°F (175°C) for about 10 minutes.
