These spinach & feta egg muffins are fluffy, savoury, golden around the edges, and packed with tender spinach and creamy, tangy feta. They make an easy grab-and-go breakfast, meal-prep lunch, post-workout snack, or light dinner.

Each egg muffin combines protein-rich eggs with nutrient-dense spinach and flavourful feta. The muffins are naturally low in carbohydrates and can easily be customised with additional vegetables, herbs, or lean protein.

They are especially convenient for busy mornings because you can prepare a batch ahead of time, refrigerate them, and simply reheat when needed.

 Recipe Overview

Recipe Name: Spinach & Feta Egg Muffins
Cuisine: American/Mediterranean-inspired
Category: Breakfast, Snack, Meal Prep
Preparation Time: 10 minutes
Cooking Time: 18–22 minutes
Total Time: Approximately 30–35 minutes
Servings: 10–12 egg muffins
Oven Temperature: 375°F (190°C)

 Ingredients

Main Ingredients

• 8 large eggs
• ¼ cup milk or unsweetened almond milk
• 2 cups fresh spinach, chopped
• ½ cup feta cheese, crumbled
• 1 tbsp olive oil
• ¼ tsp garlic powder
• ¼ tsp onion powder
• ½ tsp salt
• ¼ tsp black pepper
• ¼ tsp dried oregano or Italian seasoning, optional

Optional Ingredients

For additional flavour or texture, you can add the following:

• ¼ cup shredded mozzarella or cheddar
• ¼ cup finely diced bell pepper
• 2 tbsp chopped green onions
• ¼ cup chopped mushrooms
• 2 tbsp chopped fresh parsley
• A pinch of red pepper flakes
• ¼ cup cooked turkey sausage or chicken
• 2–3 tbsp sun-dried tomatoes, finely chopped

If adding salty ingredients such as extra feta, sausage, or sun-dried tomatoes, reduce the added salt accordingly.

 Full 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.

A well-greased pan is important because eggs can stick easily. If you prefer easier cleanup, you can also use silicone muffin cups or parchment-style liners designed for egg muffins.

2. Prepare the Spinach

Heat 1 tablespoon olive oil in a skillet over medium heat.

Add the chopped spinach and sauté for approximately 1–2 minutes, stirring frequently.

The spinach should become wilted but should not be heavily browned.

Remove the skillet from the heat and allow the spinach to cool slightly.

Important tip

Spinach contains quite a bit of water. If your cooked spinach looks particularly wet, gently squeeze or drain off excess moisture before adding it to the eggs.

This helps prevent watery egg muffins.

3. Prepare the Egg Mixture

Crack the 8 eggs into a large mixing bowl.

Add the ¼ cup milk and whisk until the eggs and milk are completely combined.

Add:

• Garlic powder
• Onion powder
• Salt
• Black pepper
• Oregano or Italian seasoning

Whisk again.

The mixture should be smooth and evenly seasoned.

4. Add Spinach and Feta

Add the slightly cooled spinach to the egg mixture.

Crumble about two-thirds of the feta cheese into the bowl, reserving the remaining feta for the tops.

If you’re using optional shredded mozzarella or cheddar, add it now.

Gently stir everything together.

Avoid aggressively mixing the ingredients; you want the spinach and cheese distributed throughout the eggs without breaking the feta down completely.

5. Fill the Muffin Tin

Pour or spoon the egg mixture evenly into the prepared muffin cups.

Fill each cup approximately ¾ full.

Don’t fill them completely to the top because the eggs will puff up as they bake.

Divide the spinach, feta, and egg mixture as evenly as possible between the cups.

Sprinkle the reserved feta over the tops.

6. Bake

Place the muffin tin in the preheated oven.

Bake for 18–22 minutes, or until:

• The centres are set.
• The edges are lightly golden.
• The tops look slightly puffed.
• A toothpick inserted into the centre comes out mostly clean.

Try not to overbake the muffins. Eggs become firm and rubbery when cooked for too long.

It’s normal for the muffins to puff significantly in the oven and then sink slightly as they cool.

7. Rest Before Serving

Remove the muffin tin from the oven and allow the egg muffins to rest for approximately 5 minutes.

Run a small silicone spatula or butter knife around the edges if necessary, then gently lift the muffins out.

Serve warm.

 Serving Suggestions

These egg muffins are delicious on their own, but you can turn them into a complete breakfast by serving them with the following:

• Fresh fruit
• Avocado
• Whole-grain toast
• Roasted potatoes
• Tomato and cucumber salad
• Greek yogurt
• Fresh berries
• Sliced tomatoes

For a Mediterranean-style breakfast, serve them with cucumber, tomatoes, olives, whole-grain toast, and a little extra feta.

For a low-carbohydrate meal, pair them with avocado and a fresh green salad.

 Meal-Prep Instructions

One of the biggest advantages of this recipe is how well it works for meal preparation.

Allow the muffins to cool completely before storing them.

Place them in an airtight food-storage container and refrigerate for up to 4 days.

To reheat

Microwave one egg muffin for approximately 20–30 seconds.

If reheating several at once, increase the time gradually and check their temperature so they don’t become overcooked.

You can also reheat them in a 325°F (165°C) oven for several minutes if you prefer a firmer exterior.

Can you freeze them?

Yes. Allow the cooked muffins to cool completely, then place them in a freezer-safe container or bag with parchment paper between layers if needed.

Freeze for approximately 2–3 months for best quality.

Thaw overnight in the refrigerator and reheat thoroughly before serving.

 Recipe Notes

1. Don’t skip draining wet spinach

Excess moisture is one of the most common reasons egg muffins become watery. Fresh spinach should be wilted, and any obvious liquid should be removed.

2. Feta provides plenty of salt

Feta cheese can vary considerably in saltiness. Taste the mixture before adding additional salt if you’re concerned about sodium.

3. Don’t overfill the muffin cups

Three-quarters full is ideal. Eggs expand as they cook.

4. Expect some shrinking

The muffins will puff up during baking and naturally deflate somewhat after coming out of the oven. This is normal and doesn’t mean anything went wrong.

5. Use room-temperature ingredients when possible

Eggs and milk that aren’t extremely cold can combine more easily and cook more evenly.

6. Chop spinach fairly small

Large pieces of spinach can make the muffins difficult to eat and may cause the filling to separate. Smaller pieces distribute more evenly.

7. Customize the cheese

Feta gives these muffins their distinctive salty, tangy flavour. Mozzarella creates a milder, stretchy texture, while cheddar gives a stronger savoury flavour.

 Benefits of Spinach & Feta Egg Muffins

These muffins can be a nutritious addition to a balanced diet.

Protein

Eggs provide high-quality protein, while feta contributes additional protein. Protein can help support normal muscle maintenance and can make a meal more satisfying.

Spinach

Spinach contributes nutrients including vitamin K, vitamin A, folate, vitamin C, and several minerals, along with fibre and plant compounds.

Healthy fats

Olive oil provides predominantly unsaturated fat. Eggs and feta also contribute fat, which helps make the muffins satisfying.

Convenient portion control

Because the mixture is divided into individual muffins, it’s easy to portion a serving and take breakfast with you.

Lower carbohydrate

The basic recipe contains relatively little carbohydrate compared with many traditional breakfast pastries, breads, or cereals. Adding potatoes, toast, fruit, or other carbohydrate-rich foods can create a more balanced meal according to your needs.

Note: Nutritional benefits depend on the complete meal and your overall diet. No single food provides every nutrient your body needs.

 Approximate Nutritional Information

The following is an estimate per muffin when the recipe makes 12 muffins, using milk and feta and excluding optional mozzarella/cheddar and additional fillings.

Actual nutrition will vary depending on the size of the eggs, brand of feta, type of milk, amount of olive oil absorbed, and other ingredients used.

 Frequently Asked Questions

Can I use frozen spinach?

Yes. Frozen spinach works very well. Thaw it completely and squeeze out as much water as possible before adding it to the egg mixture.

Can I make these without milk?

Absolutely. You can omit the milk or replace it with an unsweetened dairy-free milk. The muffins will still cook successfully.

Why did my egg muffins become watery?

The most likely causes are excess moisture from spinach or vegetables or undercooking. Sauté and drain spinach well, and make sure the centres are fully set before removing the muffins from the oven.

Can I add other vegetables?

Yes. Bell peppers, mushrooms, broccoli, tomatoes, onions, and zucchini all work. Cook vegetables that release a lot of water before adding them.

Can I make them higher in protein?

Yes. Add extra egg whites, lean cooked chicken or turkey, or another protein-rich filling. Greek yoghurt can also be served alongside them.

Are these good for meal prep?

Definitely. They’re specifically well suited to meal prep because they can be refrigerated, reheated quickly, and eaten on the go.

Can I make them dairy-free?

Yes. Omit the feta and use a dairy-free cheese alternative if desired. Use unsweetened plant milk or simply leave the milk out.

Can I make them vegetarian?

The basic recipe is vegetarian. If adding sausage or other meat, use a vegetarian alternative if you want to keep the recipe meat-free.

How do I stop them from sticking?

Grease the muffin tin thoroughly, use a quality nonstick pan, or use silicone liners. Allowing the muffins to cool for about 5 minutes also makes removal easier.

Can I eat them cold?

Yes. They can be eaten chilled, although many people prefer them warm.
