All the Pieces for This Meal
- 1 small onion - any color works, you can sub in 2 shallots too if you want.
- 1 green bell pepper - sub with red, yellow, or orange if you like it sweeter.
- 1 8 oz. package of mushrooms - cremini, button, or whichever mushrooms you prefer.
- 10 eggs - gotta have that protein packed base.
- 2 cups diced ham - something like ham steak is great here.
- 1 cup sharp cheddar cheese - or any cheese that melts well and tastes good.
- 2 Tbsp. olive oil - for sautéing the veggies.
- ½ teaspoon kosher salt - split for seasoning both veggies and eggs.
- ½ teaspoon black pepper - split the same way as the salt.
- Cooking spray - to grease the muffin tin so nothing sticks.
Each ingredient adds its own little vibe to the muffins. The veggies get tender and sweet from sautéing, the ham brings in some savory chunks, and the cheese melts right in for gooey goodness. Using olive oil for the sauté keeps things nice and flavorful but light. You’ll taste the balance from the salt and pepper split between the veggies and eggs so it all comes out just right. And don’t skip the cooking spray or you’ll have muffin stuck situations that nobody wants.
How It All Comes Together Step by Step
First, you gotta preheat the oven to 375°F. Make sure your 12-cup muffin tin is greased up real good with the cooking spray so the muffins slip out easy later.
Next, warm up the olive oil in a skillet over medium heat. Toss in the diced onion, bell pepper, and mushrooms. Let those goodies cook for about 5 to 7 minutes till they’re soft and most of the moisture’s evaporated. Don’t forget to sprinkle half of the salt and pepper now.
Now it’s time to let that veggie mix cool a little so it doesn’t scramble the eggs when you add it. While cooling, whisk the eggs in a big bowl until frothy and light.
Stir in your cooked veggies, diced ham, shredded cheddar cheese, and the rest of the salt and pepper. This is where it all comes together with those layers of flavor.
Divvy up the mixture evenly among the muffin cups, only fill about three quarters full so they got room to puff up while baking.
Bake them in the oven for 20 to 25 minutes. You’ll know they’re ready when the tops are lightly golden and the eggs are set firm but still fluffy inside.
Once baked, let them cool in the tin for 5 minutes before carefully runnin a knife around the edges to free 'em up. Serve these warm for the best experience or cool completely before refrigerating for later.
Quick Tricks That Save Your Time
- Dice your veggies the night before and keep them in the fridge so you’re ready to go in a flash.
- Use pre-sliced ham or leftover cooked ham to speed things up.
- Sauté the veggies while your oven preheats to multitask efficiently.
- Cook the muffins all at once and freeze the extras to have breakfast ready anytime.
- For a quick release, carefully open the valve once baking is done to speed up the process without overcooking.

How to Store This for Later
If you’re not eating all these muffins right away, you gotta stash them properly. First, let them cool completely before storing so the steam doesn’t cause sogginess.
Wrap each muffin individually in plastic wrap or foil to keep 'em fresher longer. Then, put them in an airtight container or a big sealable bag.
You can keep these in the fridge for up to 4 days, which makes for easy breakfast grab and go all week. For longer storage, pop them in the freezer. They keep great for about a month that way.
When reheating, you can go for quick release warmth in the microwave or a quick oven bake to keep that nice texture. Just watch the time so they don’t dry out.
