Roasted Vegetable Frittata Will Make Your Brunch Menu Shine
Flavorful roasted spring vegetables and tangy Manchego cheese come together in a savory frittata that will be the highlight of your brunch menu. This roasted vegetable frittata also makes a perfect light supper when paired with a salad of mixed greens and crusty dinner rolls.

A Rainbow of Vegetables Becomes a Meal
One night not too long ago, I needed a dinner idea and was not particularly motivated to go to the store. So, I decided to use what I had on hand: a menagerie of veggies left over from other meals, a few eggs, a wedge of cheese, and a little half and half.
My Spinach Quiche recipe was the inspiration for this frittata. I lightened it up by swapping out the heavy cream for half and half. Asparagus took center stage, accompanied by colorful red and yellow peppers, savory onion, and a little fresh thyme.
Tomatoes are a new favorite ingredient in my egg dishes, and I have found that the small grape tomatoes work very well. They have a nice flavor, not too much moisture, and don’t become too mushy when cooked.
For the cheese in this frittata, I chose a tangy Manchego cheese. I would like to say that I planned to use this cheese from the beginning. But, in reality it was just sitting in the drawer of my refrigerator, leftover from a charcuterie board the weekend before. What a wonderful surprise! Manchego is now one of my go-to cheeses for cooking.

Roasted Vegetables Dial Up the Flavor
Roasting is perhaps one of the easiest ways to cook a vegetable. And the results taste delicious. Toss the veggies in a little olive oil and sprinkle with salt and pepper.Spread them into a single layer on a baking sheet. Cook at a high temperature (my oven produces the best results at 425 degrees) until they are tender and the edges are browned.
A couple of things happen when we cook vegetables at high heat:
- They lose moisture, which causes the flavors to become more concentrated. (Have you noticed that a sun-dried tomato has a very intense flavor?)
- The natural sugars in the vegetables caramelize, causing the edges to become brown. And because of this, they taste a little sweeter.
- The outside of the vegetables remain a little crispy, while the inside becomes soft.

Notes
- You may substitute heavy cream for the half and half.
- I used a quiche dish with an inside diameter of 9-1/2 inches. You may also use a 9 inch pie plate.
- All ovens are different. Keep a close eye on your roasting vegetables to make sure they don’t burn.
- Cut your vegetables in roughly the same size. Thicker asparagus spears may require a longer roasting time.
Try your Own Version
I encourage you to try your own version of this frittata. Go to your fridge and see what you have in there that might work. Leftover broccoli, carrots, or zucchini? Roast them up, and see how good they are in a frittata.
