Cheesy Zucchini Egg Muffins
Description
Cheesy Zucchini Egg Muffins are fluffy, savoury, cheesy, and incredibly easy to make. They combine fresh grated zucchini with protein-rich eggs, gooey mozzarella cheese, and mild green onions for a delicious breakfast or snack that the whole family can enjoy.
These little egg muffins are especially useful when you want something quick and satisfying without preparing a complicated breakfast. The zucchini adds moisture, tenderness, and a subtle vegetable flavour, while the mozzarella melts beautifully throughout the muffins. Green onions add a fresh, savoury bite that balances the richness of the cheese and eggs.
They are delicious straight from the oven, but they also work wonderfully as a make-ahead breakfast. Prepare a batch on the weekend, refrigerate them, and simply reheat individual portions when you’re ready to eat.
You can serve these muffins alongside fresh fruit, avocado, tomatoes, a green salad, or whole-grain toast. They are also easy to customise with your favourite vegetables, herbs, seasonings, or cheeses.
Recipe Information

Cook Time: 20–25 minutes
Total Time: 40 minutes
Servings: 6 muffins
Course: Breakfast, Brunch, Snack
Cuisine: American-Inspired
Difficulty: Easy
Ingredients
- 2 small zucchinis, grated
- 4 large eggs
- 1 cup shredded mozzarella cheese
- 2 green onions, finely chopped
- 1 tablespoon olive oil or melted butter
- 1/2 teaspoon salt, or to taste
- 1/4 teaspoon black pepper, or to taste
Optional Ingredients
- 1/2 teaspoon garlic powder
- 1/2 teaspoon Italian seasoning
- 2 tablespoons grated Parmesan cheese
- 1/4 teaspoon red pepper flakes
- 2 tablespoons chopped fresh parsley
- 1/4 cup diced bell pepper
- 1/4 cup chopped spinach
- 2 tablespoons cooked and crumbled turkey bacon
Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 6-cup jumbo muffin pan or a standard 12-cup muffin pan. If using a standard muffin pan, you can make smaller muffins and adjust the baking time accordingly.
Silicone muffin cups or parchment liners can also be used to make removing the muffins easier.
Step 2: Prepare the Zucchini
Wash the zucchini thoroughly and grate it using the large holes of a box grater.
Zucchini contains a lot of water, so removing excess moisture is one of the most important steps in this recipe.
Place the grated zucchini in a clean kitchen towel or several layers of paper towels. Gather the towel around the zucchini and squeeze firmly over the sink or a bowl until as much liquid as possible has been removed.
The zucchini doesn’t need to be completely dry, but it should no longer be dripping wet.
Step 3: Prepare the Eggs
Crack the eggs into a large mixing bowl.
Add the salt and black pepper. If using garlic powder, Italian seasoning, or red pepper flakes, add them now.
Whisk the eggs until the yolks and whites are completely combined and the mixture looks smooth.
Step 4: Add the Vegetables and Cheese
Add the squeezed zucchini, chopped green onions, and shredded mozzarella to the beaten eggs.
Add the olive oil or melted butter.
Gently stir everything together until the zucchini, cheese, and green onions are evenly distributed throughout the egg mixture.
If you’re adding Parmesan, spinach, bell pepper, or fresh herbs, fold them in at this stage.
Step 5: Fill the Muffin Pan
Divide the mixture evenly among the prepared muffin cups.
Fill each cup approximately three-quarters full. Avoid filling them all the way to the top because the eggs will puff up as they bake.
Try to distribute the zucchini and cheese evenly so that every muffin has a good balance of ingredients.
Step 6: Bake
Place the muffin pan in the preheated oven.
Bake for approximately 20–25 minutes, or until the eggs are fully set and the tops are lightly golden.
If using a standard muffin pan to make smaller muffins, begin checking them around 15–18 minutes.
The exact baking time will depend on the size of your muffin cups and how much moisture remains in the zucchini.
Step 7: Cool
Remove the pan from the oven and allow the muffins to cool for about 5 minutes.
Run a small knife or silicone spatula around the edges if necessary, then gently remove the muffins from the pan.
Serve warm and enjoy.
Notes
Squeezing the zucchini is essential: excess zucchini water can make the egg muffins watery or prevent them from setting properly.
Use freshly grated cheese: Freshly shredded mozzarella generally melts smoothly and gives the muffins a delicious cheesy texture.
Don’t overfill the muffin cups: Eggs expand as they cook, so leave some room at the top.
Season gradually: Mozzarella can contain some salt, so taste and adjust the seasoning according to your preference.
Use olive oil or butter: both work well. Olive oil gives a lighter, savoury flavour, while butter adds richness.
Don’t overbake: Overcooking can make egg muffins rubbery. Remove them once the centre is set.
Tips for Perfect Zucchini Egg Muffins
1. Remove as Much Moisture as Possible
This is the most important tip. Zucchini naturally contains a large amount of water. If you skip squeezing it, the muffins may release water while baking.
After grating, squeeze the zucchini several times until it feels noticeably drier.
2. Don’t Use Too Much Zucchini
The recipe is balanced around two small zucchinis. If you use a very large zucchini, it may contain significantly more moisture and can change the texture.
3. Shred the Cheese Yourself
Freshly shredded mozzarella melts beautifully. Pre-shredded cheese can also work, but some varieties contain ingredients that can affect how smoothly the cheese melts.
4. Let the Muffins Rest
Allowing the muffins to cool for a few minutes makes them easier to remove from the pan and allows the egg mixture to finish setting.
5. Grease the Pan Well
Eggs can stick to muffin pans, especially around the edges. Lightly greasing each cup helps make removal easier.
6. Don’t Overmix
Once the ingredients are combined, gently stir until everything is evenly distributed. There’s no need to vigorously mix the batter.
Serving Suggestions
These zucchini egg muffins are delicious on their own, but you can easily turn them into a complete breakfast.
Serve two or three muffins with sliced avocado and fresh tomatoes.
Pair them with berries or another favourite fresh fruit for a sweet and savoury breakfast.
Serve alongside whole-grain toast for additional carbohydrates and fibre.
For brunch, arrange the muffins on a platter with fresh herbs and a simple green salad.
You can also serve them as a grab-and-go snack during the day.
Variations
Spinach and Mozzarella
Add 1/2 cup finely chopped spinach for an extra vegetable boost. Make sure excess moisture is removed from the spinach if using frozen spinach.
Mediterranean Style
Add chopped parsley, oregano, a little feta cheese, diced tomato, and black olives for a Mediterranean-inspired variation.
Spicy Zucchini Muffins
Add red pepper flakes, diced jalapeño, or a small amount of hot sauce for extra heat.
Cheddar Version
Replace some or all of the mozzarella with shredded cheddar cheese for a stronger, sharper cheese flavour.
Mushroom Version
Sauté finely chopped mushrooms before adding them to the egg mixture. Allow them to cool slightly and drain any excess liquid first.
Protein-Packed Version
Add cooked turkey sausage, chicken sausage, or turkey bacon for additional protein and a heartier breakfast.
Storage
Allow the muffins to cool completely before storing.
Place them in an airtight container and refrigerate for up to 4 days.
For longer storage, freeze the cooled muffins individually on a tray before transferring them to a freezer-safe container or bag.
They can be frozen for approximately 2 months.
To reheat from the refrigerator, microwave one muffin for about 30–45 seconds, depending on your microwave.
For frozen muffins, thaw them overnight in the refrigerator and reheat until warmed through.

Frequently Asked Questions
Can I make these muffins with one large zucchini?
Yes. One large zucchini can generally work, but make sure to squeeze out plenty of moisture after grating. The important thing is to use approximately the same amount of prepared zucchini rather than relying only on size.
Why are my zucchini egg muffins watery?
The most common reason is excess moisture from the zucchini. Make sure you squeeze the grated zucchini very well before adding it to the eggs.
Watery vegetables such as tomatoes or mushrooms can also contribute additional moisture, so cook or drain them before adding them.
Can I use cheddar instead of mozzarella?
Absolutely. Cheddar gives the muffins a stronger and slightly sharper flavour. You can also use Monterey Jack, Swiss, provolone, or a combination of cheeses.
Can I make smaller muffins?
Yes. Divide the mixture among a standard 12-cup muffin pan instead of making six larger muffins. Reduce the baking time and start checking them around 15 minutes.
Can I prepare them the night before?
Yes. You can prepare and bake them the night before, refrigerate them, and reheat them the following morning.
Can I freeze zucchini egg muffins?
Yes. Let them cool completely, wrap or store them in an airtight freezer-safe container, and freeze for up to about 2 months.
How do I prevent them from sticking?
Grease the muffin cups thoroughly or use silicone liners. Allow the muffins to cool for several minutes before removing them.
**Can I add meat?
Yes. Cooked crumbled turkey sausage, chicken sausage, ham, or turkey bacon can be added. Make sure any meat is fully cooked before adding it to the egg mixture.
Can I make this recipe without butter or oil?
Yes. You can omit the tablespoon of oil or butter, especially if you’re using a well-greased nonstick or silicone muffin pan. The texture may be slightly different.
Are these good for breakfast meal prep?
Yes. They are particularly convenient for meal prep because they can be made in advance, refrigerated, and quickly reheated.
