Ingredients

Scale
  • 10 large egg whites (about 300 ml)
  • 1/2 cup diced bell peppers (red or yellow)
  • 1/2 cup chopped spinach (fresh or frozen, thawed and drained)
  • 1/4 cup chopped onions (yellow preferred)
  • 1/3 cup grated cheddar cheese (or mozzarella for milder taste)
  • 1/2 teaspoon salt
  • 1/4 teaspoon freshly ground black pepper
  • 1/4 teaspoon garlic powder
  • Olive oil spray or butter (for greasing muffin tin)
  • Optional: chopped mushrooms (sautéed), crumbled bacon or turkey sausage, fresh herbs like chives or parsley

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. Grease the muffin tin thoroughly with olive oil spray or softened butter to prevent sticking.
  3. Finely chop bell peppers, spinach, and onions. If using mushrooms or meat, sauté them lightly for 3-4 minutes to reduce moisture.
  4. In a mixing bowl, whisk the egg whites until slightly frothy (1-2 minutes by hand or 30 seconds with an electric mixer).
  5. Add the chopped veggies, grated cheese, salt, black pepper, and garlic powder to the egg whites. Gently fold everything together with a spatula, keeping the mixture airy.
  6. Divide the mixture evenly among the greased muffin cups, filling each about 3/4 full.
  7. Bake in the preheated oven for 20-22 minutes or until the tops are lightly golden and a toothpick inserted in the center comes out clean.
  8. Remove from oven and let cool for 5 minutes before carefully running a knife around the edges to loosen the muffin cups.

Notes

Do not overfill muffin cups to avoid spillover. Drain watery veggies well to prevent sogginess. Use fresh egg whites for best fluffiness. For fluffier texture, whisk egg whites to soft peaks before folding in ingredients. Cover muffins loosely with foil if tops brown too quickly. Cool completely before refrigerating to avoid rubbery texture. Freeze individually for longer storage and reheat gently.
