Ingredients
- 8 large eggs
- 1 cup fresh spinach, finely chopped
- 1 cup shredded cheddar cheese
- ¼ cup milk
- ¼ cup finely diced onion
- 1 small bell pepper, finely diced
- ½ teaspoon garlic powder
- ½ teaspoon dried oregano
- ¼ teaspoon black pepper
- ¼ teaspoon salt
- 1 tablespoon olive oil or butter
- 2 tablespoons chopped fresh parsley, optional
How to Make Spinach & Cheese Egg Muffins
1. Prepare the Oven
Preheat your oven to 375°F (190°C).
Grease a 12-cup muffin pan thoroughly with cooking spray, butter, or a little olive oil. You can also use silicone muffin cups for easier removal.
2. Cook the Vegetables
Heat the olive oil or butter in a skillet over medium heat.
Add the diced onion and bell pepper. Cook for about 2–3 minutes, until they begin to soften.
Add the chopped spinach and cook for another 1–2 minutes, just until the spinach wilts.
Remove the skillet from the heat and allow the vegetables to cool slightly.
3. Prepare the Egg Mixture
Crack the eggs into a large bowl.
Add the milk, garlic powder, oregano, black pepper, and salt. Whisk until the eggs are completely combined and slightly frothy.
Stir in the cooked spinach mixture and shredded cheddar cheese.
If using fresh parsley, add it at this stage.
4. Fill the Muffin Cups
Divide the egg mixture evenly among the prepared muffin cups.
Fill each cup approximately ¾ full, leaving a little room for the eggs to puff as they bake.
Sprinkle a little additional cheese over the tops if desired.
5. Bake
Place the muffin pan 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.
6. Cool and Serve
Allow the egg muffins to cool in the pan for about 5 minutes.
Run a small knife or spatula around the edges if necessary, then carefully remove them.
Serve warm with fresh fruit, toast, avocado, or a simple salad.
Tips for Perfect Egg Muffins
Don’t Overfill the Muffin Cups
Eggs expand while baking, so filling each cup about three-quarters full helps prevent overflow.
Drain Excess Moisture From Spinach
Spinach naturally contains a lot of water. If you’re using frozen spinach, thaw it completely and squeeze out as much excess liquid as possible before adding it.
Don’t Overbake
Overbaking can make egg muffins rubbery. Remove them once the centers are just set.
Grease the Pan Well
Egg can stick surprisingly easily to muffin pans. A generous coating of cooking spray or butter makes removal much easier.
Let Them Rest
The muffins will continue to firm up slightly as they cool, so give them a few minutes before removing them from the pan.
Cheese Options
Cheddar gives these muffins a classic sharp flavor, but you can easily switch it up.
Try:
- Mozzarella for a mild, stretchy texture
- Feta for a salty, tangy flavor
- Monterey Jack for extra creaminess
- Swiss cheese for a slightly nutty taste
- Parmesan for a stronger savory flavor
- Pepper Jack for a little heat
You can also combine two cheeses for extra flavor.
Easy Variations
Spinach, Mushroom & Cheese
Sauté sliced mushrooms with the onion before adding the spinach.
Spinach & Feta
Replace the cheddar with crumbled feta and add a little oregano.
Ham & Spinach
Add finely diced cooked ham for an extra savory breakfast.
Bacon & Cheese
Stir in cooked, crumbled bacon before filling the muffin cups.
Tomato & Spinach
Add a small amount of finely diced cherry tomatoes. Drain excess liquid first.
Spicy Egg Muffins
Add diced jalapeño, red pepper flakes, or a pinch of chili powder.
Mediterranean Style
Use spinach, feta, tomatoes, olives, and oregano for a Mediterranean-inspired version.
Make-Ahead Breakfast
These egg muffins are especially convenient for meal prep.
Bake a batch on the weekend, allow them to cool completely, and place them in an airtight container in the refrigerator.
When you’re ready to eat, simply reheat individual muffins in the microwave until warmed through.
They make a convenient grab-and-go breakfast without requiring you to cook eggs from scratch every morning.
How to Store
Store cooled egg muffins in an airtight container in the refrigerator for up to 4 days.
For longer storage, place the cooled muffins in a freezer-safe container or bag and freeze them for up to 2 months for best quality.
To reheat from frozen, thaw overnight in the refrigerator and microwave until heated through.

- Whole-grain toast
- Fresh avocado
- Sliced tomatoes
- Fresh fruit
- Greek yogurt
- Roasted potatoes
- A simple green salad
- Fresh salsa
For brunch, arrange them on a platter with sliced avocado, tomatoes, and fresh herbs.
Frequently Asked Questions
Can I use frozen spinach?
Yes. Thaw it completely and squeeze out excess water before using it. This helps prevent watery egg muffins.
Can I make these without milk?
Yes. The milk adds a little creaminess, but you can replace it with an unsweetened dairy-free milk or simply leave it out.
Why did my egg muffins shrink after baking?
Eggs naturally puff up while baking and then settle as they cool. A small amount of shrinking is completely normal.
Can I add more vegetables?
Absolutely. Mushrooms, broccoli, zucchini, tomatoes, onions, and bell peppers all work well. Cook watery vegetables first so they don’t release too much moisture into the eggs.
Can I make mini egg muffins?
Yes. Use a mini muffin pan and reduce the baking time, checking them early because smaller portions cook much faster.
