This delicious Three-Cheese Zucchini Quiche, made lighter without heavy cream, is perfect for end-of-summer zucchini for breakfast, brunch or lunch.
Trying to adapt quiche to make it healthier is challenging because you can’t skimp on the pie crust (which is the best part, in my humble opinion. Aside from the buttery crust, quiche is also typically made with a good amount of heavy cream and cheese. I tested this Three-Cheese Zucchini Quiche a couple of times, and I think you’ll love how it turned out! I have many more healthy quiche recipes on my blog. Some others you might like with crust are my Spinach Ricotta Quiche, Chicken Quiche, or for crustless quiche recipes try Crustless Ham and Cheese Quiche or Broccoli Cheddar Quiche.
This healthy zucchini quiche recipe is lightened it up using part-skim cheeses and swaps out heavy cream for skim milk. It highlights delicious summer zucchini and basil, the ricotta creates a fluffy, creamy inside, and the cheese blend adds saltiness that is so flavorful, and even great the next day for lunch.
How To Make Zucchini Quiche:
Parbake your crust. If you want to make this faster you can use a frozen pie crust instead. Cut the zucchini into rounds and saute until tender. Add it to the crust then combine egg, milk, basil, salt and cheeses and pour that over the zucchini finishing it with Parmesan. Bake 350F until the eggs set, 50 to 55 minutes.
What are the best cheeses to use in quiche?
For this three-cheese quiche, I used part-skim ricotta, part-skim shredded mozzarella, and freshly grated parmesan cheese.
Do you sauté veggies before adding them to quiche?
Yes, sautéing the zucchini and onion before adding them to the quiche releases the water so the crust doesn’t get soggy.
Should you par bake the crust for a quiche?
Par baking the crust means you partially bake it before adding the egg filling. This process will ensure the zucchini quiche crust is crispy. Prick the crust with a fork and bake it for 15 to 18 minutes at 350° Fahrenheit.
Can you freeze zucchini quiche?
This can be refrigerated for up to 4 days, or frozen up to 3 months. To freeze quiche I like to wrap slices of quiche individually in plastic or foil and freeze. Then when I need a quick breakfast or lunch, I can pull out a slice. You can either thaw the quiche in the fridge and then microwave or microwave it for a little longer straight from frozen.
- Zucchini: Swap zucchini for yellow squash.
- Onions: Sub white or yellow onion for red onion.
- Cheese: Use shredded cheddar instead of mozzarella or asiago or Pecorino Romano in place of parmesan.
- Herbs: Substitute basil for fresh rosemary or thyme.
