I was compensated for writing the original article, “Mushrooms,” and developing the recipe found in the April 2016 issue of Today’s Dietitian. I was not compensated for sharing the column or magazine with readers on my blog. All opinions are my own.

I have a quick and easy recipe for you today, just in time for Sunday’s Mother’s Day brunch!

Frittatas are some of my go-to recipes for busy weeknight dinners or weekend brunches. I love them because they are quick and easy to put together, you can use whatever veggies are on hand in the fridge, change up the flavor profile based on the ingredients you include, and they’re an excellent source of protein. Plus, they’re relatively low in calories since you don’t have the pie crust like you do with a quiche.

Traditionally, frittatas are made in a sauté pan starting on the stove top and finished in the oven. Personally, I hate cleaning eggs out of a sauté pan and I’ve burnt my hands one too many times on the handle of the pan after it comes out of the oven. (Why do I always forget it was in the oven so it’s hot?!) So my preference is to bake frittatas in the oven in a pie dish.

I first sauté my vegetables and then transfer them to a pie dish, top with the egg mixture and cheese and bake. It takes a little bit longer and adds one more dish to clean, but it’s worth it to me. Plus it looks really pretty when serving to company! The food’s gotta look good, right?!

I have a couple of tricks up my sleeve that really boost the flavor of my frittatas. It’s your lucky day because I’m going to share them with you so your frittatas can be as jam-packed with flavor as mine are!

1. After sautéing the vegetables I deglaze the pan using water, balsamic vinegar or white wine vinegar. The deglazing process helps scrape up all those well-done veggies and adds to the umami of the veggie mixture, especially when mushrooms are involved. Check out this post by my friend and colleague Regan at Healthy Aperture to learn more about umami.

2. In addition to sprinkling the top of my frittatas with cheese before I bake them, I add cheese to the bottom of the pie dish before adding my vegetables and egg mixture on top. The layer of cheese on the bottom is almost crust-like and ensures you get cheese in every bite. No more fighting over the cheesy parts of the eggs!

So there you have my two tips for making sure your frittatas are as flavor packed as possible.

As for what’s in this frittata, mushrooms are the star of the show! As you may remember from my Creamy Pureed Mushroom Soup post, mushrooms are one of my favorite vegetables and I especially love adding them to egg dishes. They add so much depth of flavor to the dish – there’s that umami again! – and they pair well with a lot of cheeses and other vegetables.

My Mushroom Onion Quiche is a favorite in our house and with guests, and I often make it as a frittata for a lighter dinner. The recipe below is quite similar, but instead of using onions I use leeks since it’s spring and now is when they’re in season. Plus they have a sweetness that regular onions lack. To learn more about mushrooms, head over to the April issue of Today’s Dietitian Magazine and read my Culinary Corner column, which is also where this recipe was originally featured.

Before you get sidetracked with all the fun info about mushrooms, print this recipe and tape it on the fridge so your husband or kids can make it for you this weekend! You deserve a break from the kitchen (at least I know I do!).

  1. Love this Jessica! And AMEN, I totally use the pie pan too! I love the extra cheesy-ness! I like mushrooms a ton in mine, but Wayne hates them. So I usually add them on top, and fill it with bell peppers and onions! Have a wonderful Mothers Day!

    • Jessica says:

      Thanks Liz! You have to get Mr. CEO to like mushrooms better!! Bell peppers and onions are delish in frittatas too though! Thank you so much for the Mother’s Day wishes! Xo

  2. Frittatas are one of my favorite meals to make too! Have not used condensed milk-what does that do?

    • Jessica says:

      Thanks! Hope you try this one Deborah! The recipe includes evaporated skim milk (not condensed milk), which is thicker than regular skim milk but still fat-free. Great way to add creaminess without the added calories.

  3. Yum, this looks so good!! You just can’t beat a good frittata, they make it so easy to sneak those veggies into breakfast. Will definitely be trying this recipe soon!

    • Jessica says:

      Thanks so much Amber! Totally agree – it’s a great way to get veggies in at breakfast. Can’t wait to hear how you like it!

  4. Perhaps one of the best looking frittatas I’ve ever seen! I love how dense with veggies it is.

    • Jessica says:

      Wow, thanks so much Alisa!

  5. Brunch PERFECTION! I’m sure you’re not surprised that I love everything about this dish. I hope you have a wonderful Mother’s Day with your beautiful family 🙂

      Love being in such good company with you Deanna 😉

  7. Wendy says:

    This looks absolutely amazing! I would love it for dinner too.

    • Jessica says:

      Thanks Wendy! We actually eat frittatas more often for dinner, so you’re in good company!

  8. Killing me!! One of my favorite foods ever, but I’m waving good bye to eggs for awhile

    • Jessica says:

      So sorry! But now that you made your vegan tart you can make this version vegan too!

  9. This looks soooo good! Mushrooms are one my hubby’s favs, so I try to include them pretty often in my meals. I’m sure we both would love this.

    • Jessica says:

      Thanks Julie – hope you enjoy!

  10. What a great idea to spread the Parm on the BOTTOM of the pie plate to form a bit of a crust. I have two cartons of sliced mushrooms in the fridge and hope to get leeks from my CSA very soon so I can try this frittata.

    • Jessica says:

      Thanks Janice! Don’t you just love getting cheese in every bite? Can’t wait for you to try it!

    This is my first frittata and I have to say, very nice and very easy. As I only had regular milk to hand I boiled 2 and 1/4 cups down to 1 cup and added that, I also only had dried thyme so threw in, after converting, 3/4 of a tsp…all good. Also, himilayan rock salt as I only had that as well. Flavours are lovely and i thoroughly enjoyed my slice. Love the idea of cheese on the bottom. Definitely make this again.

    • Jessica says:

      Thanks so much for sharing your experience with this recipe Susan! I’m so glad you enjoyed it and will make it again. Sounds like you made some great modifications with what you had on hand. So glad to hear it worked out 🙂

      • Susan says:

        Thank u for your reply….embarking on my second making, that’s how tasty and easy it is to make.

        • Jessica says:

          That makes me so happy to hear Susan! Glad you’re enjoying it!
