  • ½ cup onion, finely chopped (optional)
  • ½ cup bell pepper, diced (optional)
  • 1 garlic clove, minced (optional)
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • ½ teaspoon dried oregano or Italian herbs

Equipment Needed

  • Large mixing bowl

  • Silicone spatula

Step-by-Step Instructions

Step 1: Prepare the Oven

Preheat your oven to 350°F (180°C).

Lightly grease a muffin tin with cooking spray or brush it with olive oil. Silicone muffin molds also work wonderfully and make removal much easier.

Step 2: Cook the Vegetables

Heat the olive oil in a skillet over medium heat.

Add:

  • Onion
  • Garlic
  • Bell pepper

Cook for about 2–3 minutes until softened.

Add the chopped spinach and cook for another minute until just wilted.

Remove from the heat and allow the vegetables to cool for several minutes.

Step 3: Whisk the Eggs

Crack the eggs into a large bowl.

Add:

  • Milk
  • Salt
  • Black pepper
  • Oregano

Whisk until the mixture becomes smooth and slightly frothy.

Step 4: Mix Everything Together

Fold the cooled vegetables into the egg mixture.

Add the crumbled feta cheese and gently stir until evenly distributed.

Step 5: Fill the Muffin Pan

Pour the egg mixture into each muffin cup until they’re about ¾ full.

Avoid filling to the top because the eggs will puff up while baking.

Step 6: Bake

Bake for 18–22 minutes, or until:

  • The centers are completely set.
  • The tops are lightly golden.
  • A toothpick inserted in the center comes out clean.

Step 7: Cool

Allow the muffins to cool inside the pan for 5 minutes.

Carefully loosen the edges with a butter knife if needed and remove them from the pan.

Serve warm or let them cool completely for storage.
