By this point, you can pretty much call me the zucchini queenie.

Or zucchini wizard. Cause we’re about to get all Harry Potter up in here.

I first shared this crustless, healthy zucchini pie about 3 years after it was actually the *bonus* recipe for a previous Zucchini Week. It was so good that I knew it had to have a permanent home on the blog. We seriously make a version of this recipe over and over again this time of year because veggies are SO fresh and beautiful and there are hundreds of different ways to customize this pie!

This gorgeous, savory pie has bites of sweet corn and juicy tomato that I love, plus tender bell pepper, savory mushrooms, and of course, plenty of zucchini to top it off. I added cheddar cheese for that melty goodness, too, but you can really use your favorite cheese here. I included tons of ways to make it your own throughout the post, plus easy tips for freezing it (AKA it’s perfect for meal prep).

BRB while I go prep this as a freezer meal for when baby comes in a couple of months!

It’s very similar to a quiche but made without any sort of crust, meaning it’s light, gluten free, packed with protein and ALL the veggies your heart can dream of. Here are the main ingredients you’ll need:

  • Green onion (or sub regular onion)

  • Grape or cherry tomatoes
  • Red bell pepper

Customize your healthy zucchini pie

Basically, any way you make this zucchini pie it’s going to be absolutely delicious and perfect for any meal of the day. Here are some easy ways to make it your own:

  • Choose your veggies: feel free to use any veggies you have available to you! We also love spinach, kale, and chopped broccoli.
  • Try a fun cheese: try out feta, pepper jack, spicy cheese, or even parmesan. YUM.
  • Add a boost of protein: this zucchini pie would be delicious with your favorite breakfast meats like ham, bacon or crumbled sausage.

Can I add a crust?

Sure! Feel free to try my sweet potato crust from this recipe, or even a traditional, buttery, flakey pie crust like this one. If you have a go-to recipe, simply pour the zucchini pie mixture into the crust and bake it up.

How to make crustless zucchini pie

  1. Prep your pan. Start by greasing a 9 inch deep dish pie pan or springform pan with nonstick cooking spray.
  2. Cook most of the veggies. Cook all those veggies except for the zucchini with olive oil, salt, and pepper until the mushrooms being to soften. Set them aside.
  3. Make the egg mixture. Whisk together the eggs, milk, flour, basil, 1/2 cup shredded cheese and a little salt & pepper.
  4. Assemble the pie. Pour the veggies into your pie pan (including the zucchini!) and spread them out. Then pour the egg mixture over, top with more cheese & bake.
  5. Cool, slice & enjoy! The zucchini pie will be done when the egg puffs up and becomes slightly golden. Let it cool, then slice and enjoy with your fav sides!

How to store, freeze & reheat this zucchini pie

You can store this crustless zucchini pie either in the refrigerator for 3-5 days, or in the freezer for up to 2-3 months.

  • To refrigerate: to refrigerate the entire zucchini pie, simply cool it completely, cover it with tin foil, and store it in your refrigerator for up to 3-5 days. When you’re ready to reheat it,  place the entire zucchini pie in the oven at 350 degrees for 15-20 minutes. Be sure to cover the entire zucchini pie with tin foil to avoid any burning in the oven. Alternatively, you can reheat individual slices in the microwave for 30 seconds to 1 minute until heated through.
  • To freeze slices: cover the slices in plastic wrap and tinfoil, and then place them into airtight containers or ziploc bags in the freezer. To reheat: unwrap your frozen slice and place it on a microwave safe dish at 30-second intervals for about 1 minute until heated through.
  • To freeze the whole pie: make sure it cools completely, then wrap in plastic wrap and cover tightly with tinfoil. When you want to reheat, thaw out a bit, then place in the oven for 20-30 minutes at 350 degrees F until it’s heated through.

Instructions

  • Preheat oven to 375 degrees Fahrenheit. Grease a 9 inch deep dish pie pan (or a 9 inch springform pan) with nonstick cooking spray.
