Recipe Details
Prep Time: 10 minutes
Cook Time: 18–22 minutes
Total Time: 30–35 minutes
Servings: 12 egg muffins
Course: Breakfast / Snack
Cuisine: Mediterranean-inspired
Difficulty: Easy
Ingredients
- 8 large eggs
- ½ cup milk or unsweetened almond milk
- 2 cups fresh spinach, chopped
- ¾ cup crumbled feta cheese
- ¼ cup finely diced red onion
- ¼ cup diced bell pepper
- 1 small garlic clove, minced
- ½ teaspoon dried oregano
- ¼ teaspoon garlic powder
- ¼ teaspoon black pepper
- ¼ teaspoon salt
- 1 tablespoon olive oil
- 2 tablespoons chopped fresh parsley
- Optional: ¼ teaspoon red pepper flakes
Instructions
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 12-cup muffin tin with olive oil or nonstick cooking spray.
For easier cleanup, you can also use silicone muffin cups or parchment liners.
2. Prepare the Vegetables
Heat olive oil in a skillet over medium heat.
Add the diced onion and bell pepper and cook for about 2–3 minutes until slightly softened.
Add the minced garlic and chopped spinach.
Cook for another 1–2 minutes, just until the spinach wilts.
Remove from the heat and allow the mixture to cool slightly.
3. Whisk the Eggs
Crack the eggs into a large bowl.
Add the milk, oregano, garlic powder, black pepper, and salt.
Whisk until the eggs are smooth and well combined.
Be careful with the salt because feta is naturally salty.
4. Combine the Ingredients
Add the cooked spinach mixture to the eggs.
Stir gently.
Fold in approximately half of the feta cheese and the fresh parsley.
If you enjoy a little heat, add red pepper flakes.
5. Fill the Muffin Tin
Pour the egg mixture evenly into the prepared muffin cups.
Fill each cup approximately ¾ full, leaving a little space because the eggs will puff as they bake.
Sprinkle the remaining feta over the tops.
6. Bake
Place the muffin tin in the preheated oven.
Bake for approximately 18–22 minutes, or until the egg muffins are puffed, set in the center, and lightly golden around the edges.
A toothpick inserted into the center should come out mostly clean.
Don’t overbake, as this can make the eggs rubbery.
7. Cool and Serve
Allow the egg muffins to cool in the pan for approximately 5 minutes.
Run a small knife or spatula around the edges if necessary and carefully remove them.
Serve warm with fresh fruit, avocado, toast, or a simple Mediterranean salad.
Description
These Spinach & Feta Egg Muffins combine the convenience of meal-prep breakfast with the fresh flavors of Mediterranean cooking.
The eggs provide a fluffy and satisfying base, while spinach adds color, freshness, and nutrients. Feta brings a creamy, tangy, slightly salty flavor that pairs beautifully with the vegetables.
Because they are individually portioned, these egg muffins are perfect for busy mornings. You can prepare a batch on the weekend and refrigerate them for quick breakfasts throughout the week.
They are also highly customizable. Add mushrooms, tomatoes, zucchini, turkey, chicken, or different herbs to create your own version.
Recipe Notes
Don’t Overfill the Muffin Cups
Eggs expand while baking. Filling each cup about three-quarters full gives them room to rise without overflowing.
Remove Excess Water
If your spinach releases a lot of moisture, cook it until the excess liquid evaporates. Too much moisture can make the muffins watery.
Use Fresh or Frozen Spinach
Fresh spinach works wonderfully, but frozen spinach can also be used. Thaw it completely and squeeze out excess water before adding it.
Don’t Overbake
Egg muffins should be just set in the center. Overcooking can make them dry and rubbery.
Watch the Salt
Feta already contains salt, so taste the mixture carefully before adding additional salt.
Helpful Tips
1. Grease the Pan Well: Eggs can stick easily, so don’t skip this step.
2. Use Silicone Liners: They make removing the muffins particularly easy.
3. Chop Vegetables Finely: Smaller pieces distribute more evenly throughout the egg mixture.
4. Cool Before Storing: Allow the muffins to cool before placing them in a sealed container.
5. Add Extra Protein: Cooked turkey, chicken, or diced lean ham can be added.
6. Make Them Spicy: Add red pepper flakes, chopped jalapeño, or a dash of hot sauce.
7. Add Fresh Herbs: Dill, parsley, basil, or chives work beautifully.
