Spinach & Feta Egg Muffins
The image shows baked spinach-and-feta egg muffins, essentially individual mini frittatas. They’re naturally gluten-free, high in protein, low in carbohydrates, and vegetarian. Similar tested recipes use eggs, spinach, feta, and optional milk/herbs, with the key trick being to remove excess water from the spinach so the muffins don’t become soggy.

Yield
12 standard-size egg muffins
Prep: 10–15 minutes
Bake: 20–25 minutes
Total: about 35–40 minutes
Ingredients
10–12 large eggs
2 cups fresh baby spinach, roughly chopped
or about 10 oz frozen chopped spinach, thawed and very well squeezed
½ cup crumbled feta cheese (about 100–120 g)
⅓ cup milk — optional, but makes the eggs softer
1–2 tbsp olive oil
¼ cup finely chopped onion
1 small garlic clove, minced
½ tsp dried oregano
¼ tsp black pepper
¼ tsp salt, or less depending on how salty your feta is
Optional: ¼ cup diced red bell pepper
Optional: pinch of red-pepper flakes
Optional: 1–2 tbsp chopped parsley or chives
Important: Feta is already salty, so taste before adding much salt.

Full Method
1. Prepare the oven
Preheat to 350°F / 180°C.
Generously grease a 12-cup muffin pan with olive oil or cooking spray. Silicone muffin molds also work particularly well for easy removal.

2. Cook the spinach
Heat 1 tbsp olive oil in a skillet over medium heat.
Add onion and cook for about 2–3 minutes until softened.
Add garlic and cook for about 30 seconds.
Add chopped spinach and cook until wilted, approximately 2 minutes.
Remove from the heat.
Very important: Let the spinach cool slightly and squeeze/drain away excess liquid. Excess moisture is one of the main causes of watery egg muffins.

3. Make the egg mixture
Crack the eggs into a large bowl.
Add:
milk
oregano
black pepper
salt
Whisk until well combined.
Don’t overbeat—you only need a smooth mixture.
4. Add the vegetables
Stir the cooked spinach mixture into the eggs.
Add the feta, reserving a little for sprinkling on top.
If using bell pepper or herbs, add them now.
5. Fill the muffin tin
Divide the mixture evenly between the 12 muffin cups.
Fill each cup approximately ¾ full rather than completely to the top because the eggs puff up during baking.

Sprinkle the remaining feta over the tops.
6. Bake
Bake at 350°F / 180°C for approximately 20–25 minutes.
They’re done when:
the centers are set,
the tops are lightly golden,
there is no liquid egg remaining in the middle.
Ovens and muffin pans vary, so use the set center as the main indicator rather than relying solely on the clock.

7. Rest
Remove the pan from the oven and let the muffins rest for 5 minutes.
Run a small knife around the edges if necessary, then gently lift them out.
They may puff considerably in the oven and shrink slightly as they cool—that is normal.
How to Make Them Look Like the Picture
For the tall, colorful muffins shown in your image:
Use fresh spinach rather than finely pureeing it.
Chop spinach into medium-sized pieces.
Use plenty of spinach but remove excess water.
Use crumbled feta in fairly large pieces.
Add a little red bell pepper for color.
Fill the muffin cups about ¾ full.
Don’t overbake—the eggs should remain moist and tender.
Allow them to cool for several minutes before removing.
Easy Variations
Mediterranean
Add:
oregano
parsley
tomato
olives
feta
Mushroom & Spinach
Sauté ½–1 cup chopped mushrooms before adding them. Cook until their moisture has evaporated.
Cheesy
Replace some of the feta with:
cheddar
mozzarella
goat cheese
Spicy
Add:
red-pepper flakes
chopped jalapeño
a little hot sauce
Higher-protein
Use additional egg whites or replace part of the milk with cottage cheese. Cottage cheese can produce particularly soft egg muffins.

Recipe Q&A
Can I use frozen spinach?
Yes. Thaw it completely and squeeze out as much water as possible before adding it. Frozen spinach works very well for egg cups.
T
The Dinner-Mom
Can I use fresh spinach without cooking it?
Yes, but cooking it first helps reduce its volume and moisture. If using raw spinach, chop it fairly finely and avoid adding excessive amounts.
Why are my egg muffins watery?
Usually because the vegetables contain too much water. Cook spinach and squeeze/drain it thoroughly. Mushrooms and tomatoes should also be cooked or well drained.

Why did my muffins collapse?
Egg muffins naturally puff during baking and then shrink somewhat while cooling. That’s normal.

Can I make them without milk?
Absolutely. Milk is optional. The muffins will still work with eggs, spinach and feta alone.
Can I substitute another cheese for feta?
Yes. Goat cheese, cheddar, mozzarella or another cheese can work. Feta gives the recipe its characteristic salty Mediterranean flavor.
Can I make them dairy-free?
Yes. Omit the feta and milk or use suitable dairy-free substitutes. The texture and flavor will change somewhat.
Can I make them gluten-free?
Yes. The basic recipe contains no wheat or flour. Check packaged ingredients such as cheese or seasonings if strict gluten avoidance is necessary. A UCLA version of spinach egg muffins is also categorized as gluten-free and nut-free.

Can I freeze them?
Yes. Allow them to cool completely, then freeze in an airtight container or freezer bag. Several comparable recipes recommend freezing for roughly 2–3 months.

How long do they keep in the refrigerator?
For best quality, about 3–5 days in an airtight container is a reasonable range; published recipes vary somewhat.

How do I reheat them?
From the refrigerator, microwave until hot, generally around 30–60 seconds, depending on your microwave and number of muffins. Avoid overheating because eggs can become rubbery.

Can I eat them cold?
Yes. They’re good warm, room temperature, or cold.
Can I make mini muffins?
Yes. Use a mini-muffin pan and reduce the baking time substantially; start checking early because the smaller portions cook faster.
Are they good for meal prep?
Definitely. That’s one of the main advantages of egg muffins: they can be baked in advance, refrigerated, and reheated for quick breakfasts or snacks.

How do I prevent sticking?
Grease the pan generously, especially around the sides. Silicone molds can make removal easier.

Can I add meat?
Yes. Cooked, crumbled turkey sausage, chicken, ham or bacon can be added. Make sure any meat is fully cooked before mixing it into the egg mixture.
Best Version for the Photo
If I were recreating the exact style in your picture, I’d use:
12 eggs + 2 cups fresh spinach + ½ cup feta + ⅓ cup milk + ¼ cup onion + garlic + oregano + black pepper + 1 tbsp olive oil.
Cook and drain the spinach first, mix everything together, fill a greased 12-cup muffin pan about ¾ full, top with extra feta, and bake at 350°F/180°C for about 20–25 minutes, until completely set.
Food-safety note: Because these contain eggs, don’t serve them while the center is still liquid. Cook until the egg mixture is fully set; then refrigerate leftovers promptly rather than leaving them at room temperature for extended periods.
