    🥘 Zucchini Mushroom Quiche Ingredients, Notes, & Substitutions

    All it takes is a handful of basic ingredients you can easily find at the store to make this delicious quiche! I recommend making my easy pie crust over using a store-bought crust for the best flavor and texture.

    🔪 How To Make A Zucchini Mushroom Quiche

    If you've never made a quiche before, there's no need to worry, as it's surprisingly straightforward and quick to prepare! Take out a 9-inch pie pan, measuring utensils, a large mixing bowl, a silicone spatula, a silicone whisk, and a large skillet to get started.

    This recipe will make 8 servings, depending on how large you cut the slices.

    Blind Bake The Crust

    Step 1: Prepare. Preheat your oven to 375°F (190°C/Gas Mark 5) and place your pie crust in the bottom of a 9-inch pie pan.

    Step 2: Top. Trim a sheet of parchment paper into a circle to fit the bottom of your pie crust, then top it with baking beads or beans until the pie crust is halfway full.

    Step 3: Par-bake crust. Once the oven has preheated, put your pie crust on the center rack and let it par-bake for 10 minutes. Then, take it out of the oven and let it cool before removing the baking beads. Set aside.

    Sauté The Vegetables

    Step 4: Melt butter. Melt 3 tablespoons (42 grams) of butter in a large skillet over medium heat.

    Step 5: Add vegetables. Add 1 cup (124 grams) of sliced zucchini, ½ cup (80 grams) of sliced or diced onion, and 2 cups (192 grams) of sliced mushrooms to the hot skillet. Cook, stirring occasionally, until tender and slightly browned (about 5-7 minutes). Drain any excess liquid and let cool while you make your quiche filling.

    Step 6: Add ingredients. Add 5-6 large beaten eggs (250 grams), 1 ½ cups (355 milliliters) of heavy cream, ½ teaspoon (1.5 grams) of garlic powder, ½ teaspoon (3 grams) each of salt & pepper, ½ teaspoon (0.5 gram) of dried basil, and ½ teaspoon (1 gram) of dried oregano to a large mixing bowl and whisk to combine.

    Step 7: Fold. Gently fold the sauteed zucchini, onions, mushrooms, and 8 ounces (227 grams) of shredded Gruyere or Swiss cheese into the egg custard filling. Then, pour the egg and veggie filling into your prepared pie crust.

    Step 8: Bake. Place your unbaked quiche (in the pie pan) on top of a baking sheet. Put the baking sheet with the quiche on the center rack and bake for 25-30 minutes at 375°F (190°C/Gas Mark 5).

    Step 9: Cool & serve. Remove your quiche from the oven and transfer it to a wire rack to cool for at least 10 minutes before slicing and serving.

    🍽️ What To Serve With Zucchini Mushroom Quiche

    💭 Angela's Tips & Recipe Notes

    • Pre-baking (aka blind baking or par-baking) your pie crust is essential. It keeps the crust from getting soggy once the egg custard is added and prevents the crust from puffing up as it bakes.
    • If needed, you can swap the heavy cream for milk or half & half, though your filling won’t be as rich. If making either of these substitutions, I recommend stirring in 1 tablespoon of flour so that your quiche will thicken and set properly.
    • For a quiche that slices beautifully, it’s important to let it cool for at least 10 minutes or longer before you cut it. Otherwise, it might fall apart.

    🥄 Make Ahead Options

    You can assemble this quiche a day in advance and refrigerate it overnight, then bake it the next day! Alternatively, you can also freeze it after baking and reheat it when needed.

    🥡 Storing & Reheating

    Allow your quiche to reach room temperature before carefully wrapping it in aluminum foil or plastic wrap, and then place it in the refrigerator and store for up to 3 days.

    Freezing Zucchini Mushroom Quiche

    You can freeze your quiche whole or in slices. Wrap it tightly with plastic wrap and then place it in an airtight container or Ziploc freezer bag and freeze for up to 3 months.

    Reheating Zucchini Mushroom Quiche

    Reheat individual slices of quiche in your microwave or put the whole quiche in the oven at 350°F (175°C/Gas Mark 4) for 15 minutes. Cover it with foil to prevent it from browning too much.

    ❓ FAQ

    Can I Use Frozen Zucchini And Mushrooms Instead Of Fresh Ones?

    Yes! While fresh vegetables are recommended for the best texture and flavor, you can use frozen zucchini and mushrooms if needed. Make sure to thaw and drain them well to remove excess moisture before folding them into the rest of the quiche ingredients.

    How Can I Prevent My Pie Crust From Becoming Soggy?

    To prevent a soggy crust, you'll want to blind-bake the pie crust before adding the creamy egg custard and vegetables. This involves partially baking the crust without the filling to help it set and become crisp. You'll also want to remove excess moisture from the zucchini and mushrooms.

    What Can I Substitute For Zucchini In This Zucchini Mushroom Quiche Recipe?

    While zucchini is one of the main ingredients in this quiche, you can experiment with other vegetables like spinach, bell peppers, or asparagus if you prefer!
