Cheesy Zucchini Quiche Recipe

A few years ago, I found this zucchini brunch recipe that's quick to prepare and freezes well, too. Just put it in the refrigerator to thaw overnight and pop it into the oven when you wake up! —Karen Howard, Lakeville, Massachusetts
TOTAL TIME: Prep: 25 min. Bake: 35 min. + standing YIELD:8 servings


  • Pastry for single-crust pie (9 inches)
  • 3 tablespoons butter
  • 4 cups thinly sliced zucchini (about 3 medium)
  • 1 large onion, thinly sliced
  • 2 large eggs
  • 2 teaspoons dried parsley flakes
  • 1/2 teaspoon salt
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon dried basil
  • 1/2 teaspoon dried oregano
  • 1/4 teaspoon pepper
  • 2 cups shredded part-skim mozzarella cheese
  • 2 teaspoons prepared mustard


  • 1. Preheat oven to 400°. On a lightly floured surface, roll dough to a 1/8-in.-thick circle; transfer to a 9-in. pie plate. Trim pastry to 1/2 in. beyond rim of plate; flute edge. Refrigerate while preparing filling.
  • 2. In a large skillet, heat butter over medium heat. Add zucchini and onion; cook and stir until tender. Drain and cool slightly.
  • 3. Whisk eggs and seasonings until blended. Stir in cheese and zucchini mixture. Spread mustard over pastry shell; add filling.
  • 4. Bake on a lower oven rack until a knife inserted in center comes out clean and crust is golden brown, 35-40 minutes. If needed, cover edge loosely with foil during last 15 minutes to prevent overbrowning. Let stand 10 minutes before cutting. Yield: 8 servings.

Recipe Note

Pastry for single-crust pie (9 inches): Combine 1-1/4 cups all-purpose flour and 1/4 tsp. salt; cut in 1/2 cup cold butter until crumbly. Gradually add 3-5 Tbsp. ice water, tossing with a fork until dough holds together when pressed. Wrap in plastic wrap and refrigerate 1 hour.

"I've been making this for at least 30 years. Everyone loves it. I use spicy, brown mustard and add some greyere cheese because that's our preference but everything else is the same. Delicious!"

"I make a similar recipe and it's one of our favorites. But I use a tube of crescent rolls for the crust, don't have to prebake. We also prefer co-jack or Mexican cheese. The rest is the same except the one thing that really makes this recipe. A big bunch of fresh basil, along with a little fresh oregano and parsley absolutely makes this dish and wouldn't bother making it without the fresh basil."

"A super tasty side dish that everybody loved and wasn't too cheesy or eggy. The star was the zucchini! I added 1/4 cup of milk and no mustard, instead added some mustard powder to the egg mixture. Used a bought pie crust. Would make this again for sure :)"

"I had to change the recipe. I had all the ingredients except a pie crust, and I was too lazy to make my own. I added the mustard to the egg mixture, then the zucchini mixture. I sprayed the pie plate with nonstick cooking spray, covered it and baked it as directed. Yummy! Didn't miss the crust at all."

"A very tasty quiche. Although I didn't use a pie crust, I spread the mustard on a pam sprayed 9" pie plate. I added a couple of sauteed mushrooms and as I didn't have mozzarella cheese on hand, used monterey jack, the rest of the recipe as is! It is easy to make and we loved it. A keeper for sure."

"We love this recipe to use the abundance of zucchini. I have sub mushriooms for zucchini in winter and added thyme,.

Question about freezing this. Would you bake ahead or freeze prior to baking? Thanks"
