Base Recipe:

• 12 large eggs
• ⅓ cup milk or half-and-half
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ¼ teaspoon garlic powder (optional but adds great flavor)

Mix-In Ideas (choose 2-3 cups total):

My go-to combination: 1 cup shredded cheddar, ½ cup diced ham, ½ cup diced bell peppers, and ½ cup chopped spinach. But truly, anything goes!

Why These Ingredients Work

Eggs are the star of the show – they provide structure, protein, and that satisfying richness that makes breakfast feel complete. The milk makes them tender and light instead of dense and rubbery.

I’ve tried making these with just eggs and no milk, and trust me, that splash of dairy makes all the difference.

Salt and pepper might seem basic, but they’re essential for bringing out the natural flavors of the eggs and whatever else you add.

The beauty of this recipe is that the eggs create a perfect vehicle for whatever flavors you want – they’re neutral enough to work with anything from Italian ingredients to Mexican to classic American breakfast flavors.

Essential Tools and Equipment

• 12-cup muffin tin
• Large mixing bowl
• Whisk or fork
• Measuring cups and spoons
• Cutting board and knife
• Cooking spray or muffin liners
• Ladle or measuring cup for pouring

Step-by-Step Instructions

Step 1: Prepare Your Workspace

Preheat your oven to 350°F and spray your muffin tin generously with cooking spray – and I mean generously! Get the bottoms and the sides. This is the number one thing that makes or breaks these muffins. If you prefer using paper liners, that works too, though I find the spray gives you better results. S

Step 2: Whisk Your Egg Mixture

Crack all 12 eggs into your large bowl. Add the milk, salt, pepper, and garlic powder if using. Whisk everything together really well – about 30-45 seconds of good whisking. You want it completely smooth with no streaks of egg white showing.

Step 3: Prepare Your Mix-Ins

Have all your chosen ingredients diced into small, bite-sized pieces. If you’re using vegetables with high water content like tomatoes or mushrooms, cook them briefly first and pat them dry. Watery vegetables will make your muffins soggy. Cooked meats should be at room temperature or slightly warm, not straight from the refrigerator.

Step 4: Distribute Mix-Ins

Here’s where you can get creative! Either mix all your chosen ingredients into the egg mixture and divide evenly among the cups, or add different combinations to each muffin for variety.

Step 5: Fill the Muffin Cups

Pour the egg mixture into each muffin cup, filling them about three-quarters full. The eggs will puff up as they bake, so you need that little bit of room.

Step 6: Bake to Perfection

Bake for 20-25 minutes until the muffins are puffed, golden around the edges, and set in the center. They should spring back when you gently press the top. If you insert a toothpick in the center, it should come out clean.

Step 7: Cool and Enjoy

Let the muffins cool in the pan for about 5 minutes. This cooling time is crucial – if you try to remove them immediately, they’ll stick and fall apart. After 5 minutes, run a butter knife around the edge of each muffin and gently lift them out.

You Must Know

The single most important thing is greasing that muffin tin really well. I’ve made these dozens of times, and the only times they stuck was when I was in a hurry and didn’t spray enough.

Personal Secret: I keep a batch of these in my freezer at all times. Sunday meal prep has become a ritual for me – I make two batches in different flavor combinations, eat one batch fresh during the week, and freeze the other for the following week. It’s like having a little insurance policy against crazy mornings.

Pro Tips & Cooking Hacks

• Use a ⅓ cup measuring cup to fill each muffin cup – perfect portion every time
• Chop all ingredients roughly the same size for even distribution
• Pat vegetables dry with paper towels before adding to prevent watery muffins
• Pre-cook any raw meat before adding to the muffins
• Silicone muffin cups eliminate sticking problems completely
• Freeze cooled muffins individually wrapped for easy grab-and-go
• Add hot sauce or salsa when reheating for extra flavor
• Make mini muffins for kids – bake for only 12-15 minutes

Flavor Variations & Suggestions

The possibilities are truly endless with these muffins! For a Western-style muffin, use diced ham, bell peppers, onions, and cheddar cheese – it’s like a Denver omelet in muffin form.

Try a Mexican-inspired version with chorizo, pepper jack cheese, diced tomatoes, and green chiles, then top with salsa and avocado when serving. Italian breakfast muffins are wonderful with mozzarella, diced tomatoes, fresh basil, and a sprinkle of Parmesan.

For Greek flavors, use feta cheese, spinach, sun-dried tomatoes, and oregano. In the fall, I love making a breakfast sausage, apple, and sage version that feels so cozy.

You can even make dessert-style egg muffins with a touch of vanilla, cinnamon, and blueberries – they’re like little Dutch baby pancakes!

Make-Ahead Options

These are perfect for meal prep! Bake them on Sunday and store in an airtight container in the refrigerator for up to one week. For longer storage, let them cool completely, wrap each muffin individually in plastic wrap or aluminum foil, and freeze in a freezer bag for up to 3 months.

To reheat refrigerated muffins, microwave for 30-45 seconds until heated through. For frozen muffins, you can either thaw them overnight in the refrigerator and then reheat, or microwave from frozen for 60-90 seconds.

You can also reheat several at once in a 300°F oven for about 10 minutes. Some people even like eating them cold – they’re perfectly safe and still delicious at room temperature.

What to Serve With Breakfast Egg Muffins

These muffins are wonderfully versatile! For a complete breakfast, serve them with fresh fruit – berries, melon, or an apple are all great choices. A slice of whole grain toast with butter or avocado makes it more filling.

On weekends when I have more time, I’ll serve them as part of a bigger brunch spread with hash browns, fresh fruit salad, and yogurt parfaits.

They’re also perfect for breakfast sandwiches – split an English muffin, add your egg muffin, and maybe a slice of cheese.

For lunch, pair them with a green salad or some raw vegetables and hummus. And of course, they’re wonderful with your morning coffee or tea!

Allergy Information

Contains: Eggs, dairy (milk and possibly cheese)

For dairy-free: Use unsweetened almond milk, oat milk, or water instead of regular milk, and skip any cheese or use dairy-free cheese alternatives. The muffins will be slightly less rich but still delicious.

Unfortunately, since eggs are the main ingredient, these can’t be made egg-free while maintaining the same structure.

This recipe is naturally gluten-free as written, which makes it great for those avoiding gluten. Just make sure all your mix-ins are gluten-free too – some processed meats contain fillers.

Storage & Reheating

Store completely cooled egg muffins in an airtight container in the refrigerator for up to one week. I like to stack them with small pieces of parchment paper between layers to keep them from sticking together.

For freezing, wrap each muffin individually in plastic wrap, then place all wrapped muffins in a large freezer bag. Press out as much air as possible before sealing. Label with the date and flavor if you’re making multiple varieties. They’ll keep frozen for up to 3 months.

To reheat from the fridge, microwave one muffin for 30-45 seconds. From frozen, microwave for 60-90 seconds, checking halfway through. You can also reheat multiple muffins in the oven at 300°F for about 10 minutes. They’re also perfectly fine to eat cold if you’re really in a rush!

Questions I Get Asked A Lot

Why are my egg muffins rubbery or tough?

Rubbery eggs usually mean they were overcooked. Eggs should be cooked just until set – they’ll continue cooking a bit even after you remove them from the oven. Also, make sure you’re not baking at too high a temperature.

Another culprit can be skipping the milk – that little bit of dairy really helps keep them tender. Try pulling them out of the oven when they’re just barely set in the center, and add that splash of milk to your egg mixture.

Can I make these without a muffin tin?

You can! Pour the entire mixture into a greased 9×13-inch baking dish and bake at 350°F for about 25-30 minutes, then cut into squares. It’s more like a frittata this way, but still delicious and meal-prep friendly.

You can also use silicone egg molds or ramekins. Just adjust the baking time accordingly – smaller portions cook faster.

My muffins stuck to the pan – help!

This happens when the pan isn’t greased well enough. Next time, really generously spray every surface that will touch the egg – bottoms and sides. Don’t just give it a quick spritz. Alternatively, use paper muffin liners or invest in silicone muffin cups, which are reusable and naturally non-stick.

If they do stick, try running a thin knife around the entire edge and underneath to loosen them.

How do I know when they’re done baking?

The tops should be lightly golden and puffed up. They should feel firm to the touch, not jiggly. Insert a toothpick in the center – it should come out clean with no wet egg on it. The edges might pull away slightly from the pan. They’ll look almost like little soufflés. Don’t worry when they deflate as they cool – that’s completely normal!

Can I use egg whites or egg substitutes?

You can use egg whites for a lower-fat version – use about 1½ cups of egg whites to replace the 12 whole eggs. They won’t be quite as rich but will still work. Egg substitutes like Egg Beaters also work well – follow the package directions for equivalents. The texture will be slightly different but still good. I personally prefer the richness of whole eggs, but I know many people have dietary reasons for using alternatives.
