Healthy Egg Muffins – Super Simple Make-Ahead Breakfast Full Of Protein

If you’re looking to save yourself a bunch of effort in the morning without sacrificing a healthy breakfast altogether, you need to try these healthy egg muffins! Full of veggies and high in protein, these egg muffins are also extremely easy to customize according to what you happen to have in your pantry and fridge.

Ever since I tried egg muffins myself at the start of a busy week, I’ve been making several batches at a time. This way, breakfast becomes one less thing to worry about on a daily basis.

During one of the first times I tried egg muffins, I had a rather watery result. I quickly realized that I needed to precook the vegetables. From there, each batch I’ve made turned out perfectly tender every single time!

These egg muffins are savory, satisfying, extremely easy to customize, and surprisingly delicious! And I’m going to share a quick breakdown of the process of making them!

What You’ll Need

For the Egg Base

• 12 large eggs (about 600 g)
• 1 tsp salt (5 g)
• 1/2 tsp black pepper (2 g)

Whenever possible, try using room-temperature eggs. They whip up much better than cold ones.

For the Broccoli, Bacon, and Sharp Cheddar Flavors

• 4 cups broccoli florets, chopped (about 360 g)
• 3 slices bacon, chopped (about 90 g)
• 1 cup sharp cheddar cheese, grated (about 110 g)
• 1/4 cup chives, sliced (about 10 g)

Aged and sharp cheddar provides an incredibly bold, savory note that complements eggs excellently.

For the Italian Sausage, Kale, and Parmesan Flavor

• 1/2 pound Italian sausage (225 g)
• 3 packed cups of kale, chopped (about 90 g)
• 1 shallot, diced (about 50 g)
• 1 garlic clove, minced
• 1 cup Parmesan cheese, grated (about 90 g)

Freshly grated parmesan melts far better and adds a distinctive nutty and savory flavor.

For the Spinach, Grape Tomatoes, and Goat Cheese Flavor

• 24 grape tomatoes, halved (about 300 g)
• 1 green onion, sliced
• 1 packed cup baby spinach, chopped (about 30 g)
• 4 oz goat cheese, crumbled (115 g)

Goat cheese becomes incredibly creamy upon baking and pairs wonderfully with sweet roasted tomatoes.

For the Muffin Tin

• 1 to 2 tbsp avocado oil (15 to 30 ml) or non-stick spray

I personally adore using avocado oil when making these egg muffins due to its mild flavor and high smoke point.

Preparation of the Egg Base

To begin with, you’ll need to preheat your oven to 350°F (175°C).

In a large bowl or measuring cup, crack your eggs. Add the salt and pepper.

I recommend using a measuring cup, as this will allow you to pour the egg mixture into the muffin tins far more easily.

Whisk the eggs and watch as their color changes from dark yellow to pale yellow.

This should take only a few seconds. You’ll know the mixture is ready when tiny bubbles appear in the egg mixture.

On the first attempt, I didn’t whisk my eggs properly due to a lack of time, and it resulted in a rather dense and heavy texture.

Pro-Tip: Try not to season your egg mixture excessively at the very beginning, as it’s already quite savory due to other ingredients.

Preparation of the Broccoli, Bacon, and Sharp Cheddar Filling

Bring some water to a simmer in a pot and add chopped broccoli into the steaming basket.

Steam the broccoli for around 5 to 6 minutes.

Your aim is for the broccoli to be crispy but tender. It should be bright green in color with a fresh scent.

After the broccoli is done cooking, place it on a plate and let it cool a little.

Next, dice your bacon into small strips and fry it in a skillet.

It should release its characteristic smell in a couple of minutes.

Place the fried bacon onto a paper towel-lined plate.

Chop the cooled broccoli into even smaller pieces.

Finally, grate the cheddar cheese and chop the chives.

Pro Tip: Never put hot vegetables inside the egg base, as this may cook the eggs and cause them to develop an unpleasant texture.

Preparation of the Sausage, Kale, and Parmesan Filling

Add the sausage into a heated skillet and cook, breaking it apart along the way.

Sausage should develop a lovely garlic smell during cooking, and there should be small crispy brown spots all over it.

At this point, remove the kale leaves from the stalks, and chop the stalks.

Dice the shallot and finely mince the garlic.

When the sausage is cooked, remove it from the skillet, leaving around 2 teaspoons of fat inside.

Place the kale and shallot into the skillet.

There might seem like too much kale, but rest assured – it’s going to wilt down.

As soon as it starts losing volume, add the garlic and cook it with the kale for another minute.

Grate the parmesan cheese.

Pro-Tip: I used to never pre-cook my kale as I expected it to soften during baking; however, it proved to be a huge mistake. Cooking it beforehand solved this problem.

Preparation of the Spinach, Grape Tomatoes, and Goat Cheese Filling

Chop the baby spinach and slice the grape tomatoes into two halves.

Slice your green onion.

This mixture requires no cooking at all; however, if your tomatoes contain a lot of water, lightly pat them with a paper towel.

Pro-Tip: This is optional, but I recommend doing this step to prevent the tomatoes from making the egg muffins watery.

Greasing the Muffin Tin

Coat a muffin tin with a generous amount of non-stick spray or avocado oil.

Trust me on this one. One batch of egg muffins glued to the muffin tin was enough for me to learn this lesson the hard way.

The muffin tin needs to be thoroughly coated. The pan must look slightly glossy, but not slippery.

Pro-Tip: I recommend greasing ceramic muffin tins, although aluminum works equally well,l provided that they are coated with non-stick spray or a thin layer of oil.

Filling the Muffin Cups

Now we’re getting to the most interesting part.

Pour a generous amount of the vegetable and meat filling into the muffin tins, followed by the egg mixture, filling the cups to the top.

The broccoli mixture is a combination of broccoli, bacon, cheddar cheese, and chives.

The sausage mixture goes in between the Italian sausage and the rest of the ingredients, followed by grated Parmesan.

Finally, the spinach mixture consists of spinach, cherry tomatoes, green onions, a nd goat cheese.

The muffin cups need to be filled. In the oven, the egg mixture will rise significantly and then slowly fall again upon cooling.

You can either add the fillings into the muffin tins, or partially fill them with the egg base, and then cover with the mixture of your choice.

Pro-Tip: It’s worth whisking the egg mixture from time to time to distribute the seasonings evenly.

Baking the Egg Muffins

Place the egg muffins into the oven and bake at 350°F (175°C).

About fifteen minutes into baking, the whole kitchen should start smelling incredible. The eggs should have released a delicious cheesy smell, and a beautiful golden crust should have formed.

Upon poking the muffin with a toothpick or fork, it shouldn’t be liquid anymore, but still soft.

Pro-Tip: Overbaking the egg muffins can lead to them developing a rubbery texture. This is why I always try to pull the muffins right as soon as they reach the right stage.

Mistakes To Avoid

Overfilling the Muffin Cups

Yes, you do need to fill them up, but only leave a tiny little bit of free space at the very top, so the muffins don’t overflow.

Using Raw Watery Vegetables

Watery vegetables will add additional water to the egg mixture and will make the eggs soupy. Precooking vegetables beforehand solves this problem easily.

Not Greasing the Muffin Tin

Even though egg muffins don’t stick to the tin easily, they will definitely do it if you don’t use any non-stick coating.

Baking For Too Long

Be extremely careful with the baking process, and never wait for the muffins to develop a brown crust on top. Take them out as soon as they are fully cooked.

Not Allowing the Eggs to Cool Down

If you try to take the muffins straight out of the oven, they are more likely to crumble. Allowing them to cool down for a couple of minutes fixes this issue.

How to Change It Up

Making Them Whole30

Just omit all dairy products in your recipe and use double the veggies and herbs in your recipes instead.

Making Them Southwestern

Instead of Italian sausage, try using some turkey sausage or chicken sausage.

Also, replace cheddar cheese with smoked paprika and pepper jack cheese.

Making Them Mediterranean Style

Replace Italian sausage with ground beef, and Parmesan with feta cheese.

Add some sun-dried tomatoes and chopped olives to enhance their unique flavor.

Storage and Serving Suggestions

One of the best features of egg muffins is that you can safely store them for a long time.

• Refrigerator: For 3 days maximum
• Freezer: Up to 3 months
• Reheating: Place in the microwave or in the oven heated to 300°F (150°C)

I find that egg muffins tend to become even better after sitting in the refrigerator overnight. All the flavors mix nicely!

I personally adore them with sliced avocado, fresh fruits, or just topped with a healthy green smoothie.

However, they are great inside a toasted English muffin, as well.

Overall, these egg muffins have revolutionized my meal-prep experience. Now breakfasts take me literally zero effort.

I hope you’ll enjoy them as much as I do, and come up with your own flavor combinations!
