Make-Ahead Egg Muffins with Ham and Cheddar
Not rated yet. Be the first.
Fluffy egg cups with ham, peppers and cheddar baked right in, twelve at a time. Make them on a quiet afternoon, freeze what you won't eat, and the rushed mornings that follow start a little kinder.
The short version
Sauté the pepper and onion, divide them with ham and cheese among 12 well-greased cups, pour in whisked eggs, and bake at 350°F for 22 to 25 minutes. Grease the tin generously; eggs stick.
What makes ours better
the tricks Nonna pretends she never taught me
-
Cook the vegetables first. Raw peppers and onions leach water into the eggs and leave soggy, weeping muffins. Two minutes in a skillet drives the water off and sweetens them.
-
Grease the tin, skip the paper liners. Egg grabs paper and tears off in strips. Butter or oil on the metal lets the muffins slide right out.
-
Fill the add-ins first, then pour the eggs. Every cup gets the same amount of ham and cheese, and nothing ends up sunk in one corner.

Steps
deep breath. you’ve got this.
-
Heat oven, grease the tin
Set a rack in the middle of the oven and heat it to 350°F. Brush every cup of a 12-cup muffin tin, including the top surface, with butter or oil.
-
Soften the vegetables
Melt the tablespoon of butter in a skillet over medium heat. Cook the pepper and onion, stirring, until they soften and the pan looks dry, 2 to 3 minutes. Let them cool for a few minutes.
About 3 min. Cook mode has a timer for this step.
-
Fill the cups
Divide the cooked vegetables, ham and cheese evenly among the 12 cups.
-
Whisk the eggs
Crack the eggs into a large measuring cup or pitcher with a spout. Add the salt, pepper and garlic powder, and whisk until the whites and yolks are fully blended with no streaks.
A pitcher makes the pour clean. A bowl and a ladle works too.
-
Pour and bake
Pour the eggs into the cups until each is about three-quarters full. They puff as they bake. Bake until the tops are set and spring back when pressed lightly, 22 to 25 minutes.
Overfilled cups spill over and weld to the tin. Leave room.
About 24 min. Cook mode has a timer for this step.
-
Rest and loosen
Let the muffins sit in the tin for 3 minutes; they will sink a little as they settle, which is normal. Run a butter knife around each edge and lift them out.

Good to know
the stuff I’d tell you over the phone
- Mushrooms, spinach and zucchini hold a lot of water. Cook them in the skillet until the pan is dry, and squeeze cooked spinach in a towel before it goes in the cups.
- No ham? Swap in an equal amount of cooked sausage or crumbled bacon, or leave the meat out and use 1½ cups of cooked vegetables.
- Silicone cups work well without any greasing. If you do use paper liners, spray them first.
- Storage. Refrigerate in an airtight container up to 5 days. Freeze on a tray, then bag, up to 3 months. Reheat in the microwave, about 45 seconds from the fridge or 60 to 90 seconds from frozen, until hot in the center.
Questions, answered
the questions my cousins text me
Why are my egg muffins watery?
Wet vegetables are the usual cause. Cook mushrooms, spinach, tomatoes and zucchini first until the pan is dry. A too-hot oven that puffs and then collapses can also weep, so check your temperature.
Why do my egg muffins stick?
Not enough grease, or paper liners. Coat the tin generously, tops included, and rest the muffins 3 minutes before running a knife around each one.
Can I make egg muffins without milk or cream?
Yes, and that is how this recipe works. Straight eggs bake up sturdy and slightly springy, which is what you want for a muffin you will reheat.
Can I freeze egg muffins?
Yes. Cool them completely, freeze on a tray until firm, then move to a freezer bag for up to 3 months. Reheat straight from frozen.
How do I know when egg muffins are done?
The tops are set, lightly puffed and spring back when you press the center. A knife inserted in the middle comes out clean.
