Cheesy Zucchini Quiche

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
  • Makes
    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


  • 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.
  • In a large skillet, heat butter over medium heat. Add zucchini and onion; cook and stir until tender. Drain and cool slightly.
  • Whisk eggs and seasonings until blended. Stir in cheese and zucchini mixture. Spread mustard over pastry shell; add filling.
  • 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.
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 found this recipe in a magazine years ago. Somehow I misplaced it. The sight of beautiful zucchini triggered me and I typed in the best zucchini quiche recipe. ?? Still fiya ??

    We absolutely loved this!! My family is a big fan of quiche and I'm always looking for new spins on the familiar. This one did not disappoint! I made two of them. The only thing I did differently was vary the cheese, since I was out of mozzarella. One quiche had monterey jack and the other, sharp cheddar. Both worked beautifully. Spreading mustard on the crust really made a difference. This is one quiche I'll make again and again!

    I've made this for years. It was a Pillsbury bakeoff winner many years ago during crescent rolls. I substitute shredded Italian Cheese blend and use 2 Tbls of dried parsley flakes, as well as 6 cups of sliced zucchini to make a very large 12" zucchini pie.

    Delicious recipe!! It was a hit! I calculated the nutrition facts for the recipe and got different values...lower numbers actually. I originally calculated it because I substituted olive oil for butter and wanted to compare the two. I ended up calculating the original recipe as well and found a different number profile. I'm an RDN, so I do this sometimes. I got lower calories, sat fat, cholesterol and sodium..numbers that might make this more appealing than it already is! Just wanted to let you know - I don't expect this to be posted.

    Made this tonight without the crust, and it was delicious. I spread the mustard on the bottom of the pie plate and it gives the recipe a little zip with each taste.

    I haven't made the recipe yet - but have a question regarding freezing. Do you cook it, then freeze, then warm up? Or freeze the uncooked casserole, thaw, then bake as directed? Thanks!

    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.
