Prep Time: 10 minutes
Cook Time: 18–22 minutes
Total Time: 30–32 minutes
Servings: 12 egg muffins
Ingredients
8 large eggs
½ cup milk or unsweetened almond milk
2 cups fresh spinach, finely chopped
1 cup shredded cheddar cheese
¼ cup grated Parmesan cheese
¼ cup finely diced onion
1 small garlic clove, minced
½ teaspoon salt
¼ teaspoon black pepper
½ teaspoon Italian seasoning
¼ teaspoon red pepper flakes, optional
1 tablespoon olive oil or cooking spray
2 tablespoons chopped fresh parsley or chives, optional
Instructions
1. Prepare the oven
Preheat your oven to 375°F (190°C).
Lightly grease a 12-cup muffin tin with cooking spray or olive oil.
For easier cleanup, you can also use silicone muffin cups.
2. Prepare the spinach
Heat a small skillet over medium heat and add the olive oil.
Add the diced onion and cook for 2–3 minutes until softened.
Add the garlic and chopped spinach.
Cook for another 1–2 minutes, just until the spinach wilts.
Remove from the heat and allow it to cool slightly.
Tip: If the spinach releases a lot of water, squeeze or drain it before adding it to the eggs. This helps prevent watery egg muffins.
3. Make the egg mixture
Crack the eggs into a large bowl.
Add the milk, salt, black pepper, Italian seasoning, and red pepper flakes if using.
Whisk until the eggs are completely combined and slightly frothy.
4. Add the cheese and vegetables
Stir in:
Cooked spinach
Onion and garlic
¾ cup shredded cheddar
Parmesan cheese
Fresh parsley or chives, if using
Mix gently until everything is evenly distributed.
5. Fill the muffin tin
Divide the mixture evenly among the 12 muffin cups.
Fill each cup approximately ¾ full, leaving room for the eggs to puff up during baking.
Sprinkle the remaining cheddar cheese over the tops.
6. Bake
Place the muffin tin in the preheated oven.
Bake for 18–22 minutes, or until the egg muffins are puffed, lightly golden, and set in the center.
To test, insert a toothpick into the center of one muffin. It should come out mostly clean.
7. Cool and serve
Let the egg muffins cool in the pan for 5 minutes.
Run a small knife around the edges if necessary, then gently remove them.
Serve warm with fresh herbs, avocado, tomatoes, or your favorite breakfast sides.

Q&A
Q: Why are my egg muffins watery?
The most common reason is excess moisture from spinach or other vegetables. Cook the spinach first and squeeze out excess liquid before adding it.
Q: Can I use frozen spinach?
Yes. Thaw it completely and squeeze out as much water as possible before using.
Q: Can I make these without milk?
Yes. Simply omit the milk. The muffins will still work, although the texture may be slightly firmer.
Q: Can I use different cheese?
Absolutely. Mozzarella, Monterey Jack, Swiss, feta, pepper jack, or Gouda are excellent options.
Q: Can I make these ahead of time?
Yes. They’re excellent for meal prep and can be refrigerated or frozen.
Q: How do I stop them from sticking?
Grease the muffin tin generously or use silicone muffin liners.
Q: Why did my egg muffins deflate?
Egg muffins naturally puff up while baking and then settle slightly as they cool. That’s normal.
Q: Can I add more vegetables?
Yes. Mushrooms, bell peppers, broccoli, zucchini, tomatoes, and onions all work well. Cook vegetables with high water content first.
Q: Are these keto-friendly?
The basic recipe is relatively low in carbohydrates and can fit many low-carb or keto meal plans. Check the specific nutrition of your ingredients.
Q: Can I add meat?
Yes. Cooked bacon, ham, chicken, turkey sausage, or breakfast sausage can be added.
Q: Can I eat them cold?
Yes. They’re safe to eat cold once properly refrigerated, although many people prefer them warmed.
Q: What can I serve with egg muffins?
Try avocado, fresh fruit, tomatoes, cucumber, Greek yogurt, salsa, or a simple green salad.
