Ingredients
For the muffins:
10 large eggs (the base of every muffin)
1/4 cup milk (makes the texture tender, not rubbery; any milk works)
1 cup baby spinach, chopped (wilts down to almost nothing)
1/2 bell pepper, diced (any color; red is sweetest)
1/4 onion, diced (yellow or white)
1/2 cup cooked crumbled sausage or bacon, optional (adds savory depth; skip for vegetarian)
3/4 cup shredded cheddar, divided (half mixed in, half on top)
1/2 tsp salt
1/4 tsp black pepper
How to Make Breakfast Egg Muffins
Heat and prep. Set the oven to 375°F. Grease every cup of a 12 cup muffin tin well with oil or cooking spray. Eggs stick fast, so do not skimp here.
Whisk the base. Crack 10 eggs into a large bowl. Add milk, salt, and pepper. Whisk until the yolks and whites are fully combined and slightly frothy.
Add the fillings. Stir in the chopped spinach, diced bell pepper, diced onion, and sausage or bacon if using. Fold in half the shredded cheddar. The mixture for these breakfast egg muffins should look colorful and evenly mixed.
Fill the tin. Pour or ladle the egg mixture into the prepared cups, filling each about three quarters full. The muffins puff as they bake.
Top with cheese. Sprinkle the remaining cheddar over each cup. This gives every muffin a golden cheesy top.
Bake. Bake 18 to 22 minutes, until the centers are set and the tops are lightly golden. A knife inserted in the center should come out clean.
Cool and release. Let the muffins cool in the tin for 5 minutes. Run a thin knife around each edge, then lift out. Serve warm.
Tips for the Best Breakfast Egg Muffins
Grease generously. Egg muffins stick to everything. Oil, butter, or silicone liners all work. Paper liners tend to stick.
Do not overfill. Three quarters full is the sweet spot. Fuller cups overflow and bake unevenly.
Chop vegetables small. Small dice cook through in 20 minutes. Large chunks stay raw in the center.
Whisk well. Fully beaten eggs bake up fluffy. Streaks of unmixed white turn rubbery.
Check for doneness. The centers should not jiggle. Eggs are safe at 160°F internal temperature, per USDA food safety guidelines.
Cool before storing. Warm breakfast egg muffins create steam in containers, which makes them soggy. Cool completely first.
Easy Variations
Veggie only. Skip the meat and add mushrooms, zucchini, or cherry tomatoes.
Southwest style. Swap cheddar for pepper jack. Add diced green chiles and a pinch of cumin.
Mediterranean. Use feta instead of cheddar. Add sun dried tomatoes and a little oregano.
Meat lover. Use both sausage and bacon. These breakfast egg muffins turn extra hearty.
Dairy free. Skip the cheese and use unsweetened almond milk. The muffins still set firmly.
Mini muffins. Use a mini muffin tin for bite size breakfast egg muffins. Bake 12 to 14 minutes.
Storage and Make Ahead
Breakfast egg muffins are built for the fridge. Store cooled muffins in an airtight container for up to 5 days. Reheat in the microwave for 30 to 45 seconds, or in a 350°F oven for 8 to 10 minutes.
For longer storage, freeze them. Wrap each muffin individually, then place in a freezer bag for up to 3 months. Thaw overnight in the fridge, or microwave from frozen for about 90 seconds.
Do not leave cooked egg muffins at room temperature for more than 2 hours.
Serving Ideas
Two breakfast egg muffins with fresh fruit make a complete breakfast. Add toast or a smoothie for bigger appetites. For brunch, serve a platter of these muffins next to our blueberry muffins so guests can mix and match.
Pack them for road trips, lunchboxes, or post workout snacks. For a game day spread, pair them with chicken wings for a savory snack table.

Can I freeze breakfast egg muffins? Yes. Wrap individually and freeze up to 3 months. Thaw in the fridge overnight or microwave from frozen.

How do I know when breakfast egg muffins are done? The tops turn lightly golden and the centers feel set, not jiggly. A knife in the center comes out clean.
