Ingredients You’ll Need
For the Base:

- 1/4 teaspoon sea salt – enhances natural flavors without overpowering
- 1/8 teaspoon black pepper – adds subtle warmth and depth
For the Filling:
- 2 cups fresh spinach, roughly chopped – contributes vitamins, minerals, and fiber
- 100 grams feta cheese, crumbled – delivers tangy, salty Mediterranean flavor
For Preparation:
- Butter or olive oil for greasing – prevents sticking and ensures easy removal
Step-by-Step Instructions
Prepare Your Workspace
Preheat oven to 350°F (175°C) and thoroughly grease a 12-cup muffin tin. Silicone muffin tins work particularly well for easy removal, but metal tins work fine with proper greasing.
Create the Egg Base
In a large mixing bowl, crack all 12 eggs and whisk thoroughly until completely combined. Season with sea salt and black pepper, whisking again to distribute seasonings evenly throughout.
Add the Vegetables
Add roughly chopped spinach to the seasoned eggs and whisk again to ensure the spinach is evenly distributed. The spinach will wilt during baking, so don’t worry if it seems like a lot initially.
Fill the Muffin Cups
Divide the egg and spinach mixture evenly among the 12 muffin cups, filling each about halfway. Depending on egg size, you may have a little extra mixture for additional muffins.
Add the Cheese
Sprinkle crumbled feta cheese over each filled muffin cup, distributing evenly for consistent flavor in every bite.
Bake to Perfection
Transfer the muffin tin to the preheated oven and bake for 18-20 minutes, until the center of each egg muffin is completely set and no longer jiggly. The tops should be lightly golden.
Cool and Store
Allow muffins to cool slightly before removing from the tin. Serve immediately or store in airtight containers in the refrigerator for up to 5 days.
Recipe Notes & Tips
Silicone vs. Metal – Silicone muffin tins make removal easier, but metal tins work well with thorough greasing.
Spinach Preparation – Fresh spinach works best; if using frozen, thaw completely and squeeze out excess moisture.
Cheese Options – While feta is featured, cheddar, goat cheese, or mozzarella work equally well.
Doneness Test – Centers should be completely set with no jiggling when gently shaken.
Storage Success – Store in single layers to prevent sticking and maintain shape.
