Vegetarian Frittata Recipe with Butternut Squash & Mushrooms

A great frittata recipe can be life-changing when it comes to putting a healthy brunch or dinner on the table with minimal effort. This vegetarian frittata recipe takes advantage of all of the flavors and nutrients of some of our favorite veggies - hello, butternut squash and mushrooms - while only taking 35 minutes to make.

An added bonus? Leftovers can be reheated the next day (more on that later)!

And the beauty of frittatas, besides the ease of preparation, is that they're interminably adaptable to almost any palate. If butternut squash and mushrooms aren't your thing, branch out to other vegetables, such as roasted peppers, zucchini or asparagus (see my asparagus crustless quiche for another version). Or add some chopped ham, turkey sausage or crumble bacon. It's one of those great clear-out-the-fridge kind of meals.

How do you make a frittata?

• It couldn't be easier! If you have an oven-proof skillet, some eggs and seasonings, you can make a frittata.
• Cook the vegetables: If you are adding vegetables to your frittata, be sure to cook them before adding the eggs. Why? Two reasons. First, the eggs are not cooked for long enough to allow the vegetables to soften, particularly with denser veggies like butternut squash. Second, many vegetables (I'm looking at you, mushrooms!) release moisture when cooking, which will produce a watery frittata.
• The eggs: In this light frittata recipe, I used a combination of whole eggs and egg whites; however, you can also use exclusively whole eggs. Could you use just egg whites? Sure, but I find that the flavor suffers. Also, you miss out on the protein that egg yolks offer in abundance.
• The pan: Be sure to use a skillet that is ovenproof. While I used a nonstick skillet (affiliate link) for this recipe, cast iron (affiliate link) is also a great option.
• Stovetop & oven: Once the vegetables are cooked, add the egg mixture to the skillet. The first stage of cooking happens on the stovetop. Once the eggs are set on the edges and beginning to set on top, which takes about 5 minutes, pop the frittata into the oven. The frittata cooks the rest of the way under the broiler. This takes just a few minutes, so be sure to keep an eye on it.
• Cut into wedges and serve.

Can frittatas be reheated?

• Absolutely! I do this all the time and consider the reheating option one of the benefits of cooking frittatas. Serve up part of the frittata for dinner and save the rest for breakfasts over the next couple of days.
• Cut a wedge of the frittata and place it on a microwave-proof plate.
• I suggest reheating the frittata on 50% power in the microwave. This should take about 30 seconds, give or take, depending on the strength of the microwave.

What you need for this vegetarian frittata recipe:

• Eggs: Of course! As mentioned above, I used a combination of whole eggs and egg whites, but you can use all whole eggs if you prefer (7 or 8 eggs should do the trick).
• Butternut squash:I picked up some pre-cut butternut squash at the grocery store because, honestly, peeling butternut squash is one of my least favorite kitchen tasks. Paying a little more money is well worth sparing myself the aggravation. I cut the butternut squash into ½-inch pieces and quickly blanched them in boiling water before sautéing them in a skillet.
• Mushrooms: Crimini or or white mushrooms will work. Wipe them with a damp paper towel (don't rinse under water!) and slice thinly.
• Seasonings: Smoked paprika and rosemary is one of my favorite spice pairings. I use it in these potatoes and even on popcorn (you'll never eat popcorn any other way once you've tasted this recipe!). And don't forget the salt and pepper, and a sprinkle of fresh parsley.
• Parmesan cheese: Just a couple of tablespoons will do the trick. If you don't have Parmesan on hand, feel free to substitute with asiago or Romano cheese.
