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

Ingredients

  • 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

Directions

  • 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.

    This morning is the first time I've made this with the mustard. I'm not sure if I'm gonna like it but I otherwise love this recipe. My mom lives downstairs and asks me to make it once a month.

    This is a great way to use up homegrown zucchini and other veggies. I used 4 eggs with a splash or so of whipping cream and added some bacon. Its very easy with the store bought pie dough and since 2 come in a package you can double it and make 2 quiches.

    I used both zucchini and yellow squash as both vegetables seem to "need" something. My quiche was great and colorful. I also used different cheeses. If I only had shredded cheddar, that's what I used. So easy and tasty

    I have made many quiches and this one was by far the best. I am sure that it is because I never use this much cheese, but the addition of the mustard was the key! Wow! I had to eat two pieces. I followed the recipe with a couple of changes due to what I had on hand. I addEd a yellow squash in place of one of the zucchini, I did not have any parsley, used a pilsbury rolled pie crust, Dijon mustard rather than regular and sprinkled the top with scallions.

    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!
