These broccoli cheddar frittatas are perfect for make-ahead breakfasts on busy mornings or weekend brunch. Baked in a muffin pan, they are easy to assemble. I roast broccoli florets with red onions. Then I pour the egg mixture into the muffin cups and top each one with grated cheddar before they bake.

Why You’ll Love This Recipe
These vegetable frittatas are a simple portioned out breakfast. Whether you eat them at home or on the go, you can roast the vegetables in advance and you also can bake the frittatas ahead of time. Then you can be ready for the week.
This easy egg recipe is also fancy enough for weekend brunch. I will never say no to making a frittata the traditional way in a pan, starting on the stove and then baking it in the oven. However, there is something that just seems elegant about an egg muffin instead of a slice from a standard size frittata.
You can substitute with other roasted vegetables. If you have leftover roasted veggies from another meal, you can chop them, if necessary, and use them in this recipe.
The Ingredients

This is what you need:
- Broccoli: It’s best if the florets are small to medium. They will shrink a little after you roast them, but keep in mind that they need to fit in the muffin cups.
- Red onions: I dice the onions, so they cook and soften quickly while roasting together with the broccoli.
- Cheddar and broccoli are a classic combo in soups and casseroles. Here they work their magic with eggs. You can buy grated cheddar or shred it off a block.
- Eggs: The recipe calls for 9 large eggs.
- Milk: Any type of milk will work whisked into the eggs.
- Parsley: I stir chopped fresh herbs into the egg mixture, and then I also sprinkle the baked cups with parsley right when they’re out of the oven.
- Kosher salt and black pepper season the eggs as well as the broccoli and onions when they roast.
- Olive oil: I toss the broccoli and onions in oil for roasting.
How To Make These Broccoli Frittatas
Preheat the oven to 400 degrees F. Line a sheet pan with parchment paper.
1. Prep the broccoli and onions. Toss them with oil, salt and pepper on the prepared baking sheet and spread them into a single layer.
2. Roast the broccoli and onions. Give them 12-14 minutes. The broccoli should be crisp-tender and bright green and the onions should soften.

Grease a 12-cup muffin pan with non-stick cooking spray. You can use a silicone mold instead of a traditional muffin pan.
3. Stir together the eggs, milk, parsley, salt and pepper in a large bowl. If you have a mixing bowl that has a spout at one end, this will make it easier to pour into the cups.
4. Fill the muffin cups with roasted broccoli and onions.

5. Pour in the egg mixture and top with cheddar cheese. The cups should be about 3/4 full.
6. Bake the frittatas for 15 minutes until they puff up and pull away from the sides of the pan. They should be set in the middle.

Serving
You can serve these veggie frittatas warm or at room temperature. That makes them good if you are having people over for brunch and you have a big spread with different sweet and savory dishes. Include a bottle of hot sauce on the side, always a must with eggs.
Leftovers & Storage
I usually bake these frittatas for myself and eat them cold as leftovers. I chop them and toss them with greens in a salad or with cooked grains. It’s a great way to make an entree-worthy salad especially for lunch.
Store the frittatas in an airtight container in the refrigerator up to 5 days. You can warm them with a quick zap in the microwave for 10-12 seconds. Don’t do it too long or they will get a rubbery texture. To freeze, wrap each one in plastic wrap and then put them in the same container. Thawing them overnight in the fridge and then reheating them works best. You can store them in the freezer up to 1 month.

Made these for Christmas Eve brunch. Came out perfectly. Only change was using yellow onions instead of red. Will definitely make again.
