EasyBreakfast

Make-ahead egg muffins with veggies and cheese. Perfect for busy mornings. Ready in 30 minutes, protein-packed, and freezer-friendly.

These egg muffins are my go-to for busy weekday mornings. You can make a batch on Sunday and have breakfast ready for the whole week. They take about 30 minutes from start to finish, and you only need one bowl and a muffin tin.

The eggs bake up fluffy and tender, with little pockets of melted cheese and soft veggies. You can eat them warm right out of the oven, or grab them cold from the fridge and go. They're just as good at room temperature.

This recipe is flexible, too. Use whatever vegetables you have in the fridge, or swap the cheese for something you like. It's hard to mess up, and that's the point.

About the Ingredients

8 large eggs

Use fresh eggs for the best texture. If you need to make these dairy-free, you can omit the cheese and use a splash of unsweetened almond milk instead.

1/2 cup (120ml) milk

Any milk works – dairy, almond, oat. It adds a bit of moisture and makes the eggs softer.

1/2 teaspoon salt

Adjust to your taste. If you use salty cheese like feta, you might want to reduce the salt.

1/4 teaspoon black pepper

Freshly ground is best, but pre-ground is fine.

1 cup (100g) chopped spinach

Fresh or frozen (thawed and squeezed dry). If you use frozen, make sure to remove the excess water so the muffins aren't soggy.

1/2 cup (75g) diced bell pepper

Any color works. Red, yellow, or orange are sweeter; green is a bit more bitter.

1/2 cup (75g) diced onion

Yellow or white onion is fine. You can also use a shallot for a milder flavor.

1 cup (120g) shredded cheddar cheese

Sharp cheddar gives a strong flavor. You can also use mozzarella, Monterey Jack, or a dairy-free shred.

Step-by-Step Instructions

1. Preheat and Prep

Preheat your oven to 375°F (190°C). Grease a 12-cup muffin tin with butter or non-stick spray.

2. Chop the Veggies

Finely chop the spinach, bell pepper, and onion. If using frozen spinach, make sure it's thawed and squeezed dry.

3. Whisk the Eggs

In a large bowl, whisk together the eggs, milk, salt, and pepper. Whisk until the yolks are broken and the mixture is uniform – about 30 seconds.

4. Add the Fillings

Stir in the chopped spinach, bell pepper, onion, and shredded cheddar cheese. Mix until everything is evenly distributed.

5. Fill the Muffin Tin

Pour the egg mixture into the prepared muffin tin, filling each cup about 3/4 full. Use a ladle or a measuring cup for easy pouring.

6. Bake

Bake for 20-25 minutes, until the muffins are set and the tops are lightly golden. A knife inserted into the center should come out clean.

7. Cool and Serve

Let the muffins cool in the pan for 5 minutes, then run a knife around the edges to loosen them. Serve warm, or let them cool completely and store.

Pro Tips

1

Chop the veggies small so they distribute evenly.
2

Use a cookie scoop to pour the egg mixture into the cups – it's less messy.
3

Let the muffins cool in the pan for 5 minutes before removing. This helps them set.
4

If you're freezing them, wrap each muffin individually in plastic wrap, then place in a freezer bag.

How to Store EasyBreakfast

Refrigerator

Store in an airtight container in the fridge for up to 4 days.

Freezer

Freeze in a single layer on a baking sheet, then transfer to a freezer bag. They'll keep for up to 3 months.

Reheating

Microwave a muffin for 30-60 seconds, or reheat in a toaster oven at 350°F (175°C) for 5-10 minutes.

Delicious Variations

  • Add cooked crumbled sausage or bacon for a meatier breakfast. Just make sure it's fully cooked before adding.
  • Use feta cheese and sun-dried tomatoes for a Mediterranean twist.
  • Swap the spinach for kale or Swiss chard – just chop it finely.

Frequently Asked Questions

Q: Can I make these egg muffins without cheese?

Yes, just omit the cheese. The muffins will still hold together, but they'll be a bit less rich. You can add a tablespoon of nutritional yeast or a dollop of Greek yogurt for extra flavor.

Q: How do I know when the egg muffins are done?

They're done when the tops are set and lightly golden, and a knife inserted into the center comes out clean. This usually takes 20-25 minutes at 375°F (190°C).

Q: Can I use egg whites instead of whole eggs?

Yes, you can use 12 egg whites instead of 8 whole eggs. The texture will be a bit less rich, but they'll still taste great.

Q: Why did my egg muffins stick to the pan?

Make sure you grease the muffin tin generously, even if it's non-stick. Also, let them cool for 5 minutes before removing – they release more easily when slightly cooled.

I hope these egg muffins make your mornings a little easier. Give them a try and let me know how you like them. Low and slow, friend.
