Cheesy Zucchini Quiche is a great way to enjoy fresh veggies wrapped up in a flaky crust with plenty of melted cheese. This quiche is filled with tender zucchini, eggs, and creamy cheese that comes together in a golden, satisfying bake. It’s light but filling, making it perfect for breakfast, lunch, or a light dinner.

I love making this quiche when zucchini is in season at the farmers market because it tastes so fresh and bright. A little tip I’ve picked up is to gently sauté the zucchini first to soften it and bring out its natural sweetness before mixing it into the eggs and cheese. It really makes a difference in the flavor and texture!

This quiche is one of those dishes I like to serve with a simple green salad or some fresh fruit on the side. It’s always a crowd-pleaser, whether for a family brunch or an easy weeknight meal. Plus, leftovers heat up wonderfully, so I enjoy having it ready to go for busy days.

Key Ingredients & Substitutions for Cheesy Zucchini Quiche

Pie crust: A pre-made 9-inch crust saves time, but homemade pie dough works great if you want freshness. If gluten-free is needed, try store-bought gluten-free crust or a crust made from almond flour.

Zucchini: Grated zucchini adds moisture and mild flavor. Remember to salt and squeeze it to avoid a soggy quiche. If zucchinis are small, use 3 medium, but 2 large might work too.

Cheese: I like a mix of cheddar and mozzarella for melt and flavor. Gruyère is a tasty swap for a nuttier taste. Parmesan adds a nice sharp finish—don’t skip it!

Eggs & cream: The eggs bind everything, and cream gives richness. Whole milk works well for a lighter option, but avoid skim milk as it makes the filling too runny.

Herbs: Dried thyme or fresh dill adds subtle earthiness. Fresh dill or parsley for garnish brightens the presentation and taste.

How Do I Keep Zucchini from Making the Quiche Watery?

Water in zucchini can make the quiche soggy, so this step is crucial:

  • Grate zucchinis and sprinkle with salt; let sit 10 minutes to draw out liquid.
  • Wrap the grated zucchini in a clean towel or cheesecloth and twist firmly to squeeze out all moisture.
  • Skip this, and your quiche won’t set firmly and could become watery.

Be patient here! You can press and squeeze as much as possible, even over a sink or bowl. This little extra effort makes a big difference in texture.

Equipment You’ll Need

  • 9-inch pie dish – fits the crust perfectly and helps the quiche bake evenly.
  • Box grater – makes quick work of shredding zucchini and cheese.
  • Skillet – for sautéing onions and garlic to bring out their flavors.
  • Large mixing bowl – roomy enough to mix the eggs, cream, and veggies without spills.
  • Whisk – blends the eggs and cream smoothly for a creamy filling.
  • Clean kitchen towel or cheesecloth – essential for wringing out excess water from zucchini.

Flavor Variations & Add-Ins

  • Try adding cooked bacon or ham for a smoky, meaty twist.
  • Swap zucchini for spinach or kale if you want a greener, earthier taste.
  • Use feta cheese instead of cheddar for a tangy Mediterranean touch.
  • Mix in some roasted red peppers or sun-dried tomatoes to add sweetness and color.

Easy Cheesy Zucchini Quiche Recipe

How to Make Cheesy Zucchini Quiche

Ingredients You’ll Need:

  • 1 pre-made pie crust (9-inch) or homemade pie dough
  • 3 medium zucchinis, grated
  • 1 teaspoon salt (for draining zucchini)
  • 1 tablespoon olive oil or butter
  • 1 small onion, finely chopped
  • 4 large eggs
  • 1 cup heavy cream or whole milk
  • 1 1/2 cups shredded cheese (a mix of cheddar and mozzarella, or Gruyère)
  • 1/4 cup grated Parmesan cheese
  • 2 cloves garlic, minced
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon dried thyme or fresh dill
  • Fresh dill or parsley for garnish (optional)

How Much Time Will You Need?

This recipe takes about 15 minutes for preparation and around 35-45 minutes for baking. Plan for a total of roughly 50-60 minutes from start to finish, including time to drain the zucchini and cool the quiche slightly before serving.

Step-by-Step Instructions:

1. Preparing the Pie Crust:

Preheat your oven to 375°F (190°C). Roll out the pie crust and fit it into a 9-inch pie dish. Use a fork to prick the bottom of the crust gently. This stops it from puffing up while baking. Set the crust aside for now.

2. Preparing the Zucchini:

Grate the zucchinis into a large bowl. Sprinkle them with 1 teaspoon of salt and let sit for 10 minutes. This draws out moisture from the zucchini. After 10 minutes, place the grated zucchini into a clean kitchen towel or cheesecloth and squeeze out as much water as you can. This helps keep your quiche from becoming soggy.

3. Cooking the Onion and Garlic:

Heat olive oil or butter in a skillet over medium heat. Add the finely chopped onion and cook until it’s soft and translucent, about 3-4 minutes. Stir in the minced garlic and cook for another minute. Remove the pan from heat and set aside.

4. Mixing the Filling:

In a large bowl, whisk together the eggs and cream (or whole milk) until smooth and combined. Add in the cooked onion and garlic, the drained zucchini, shredded cheese, Parmesan cheese, black pepper, and thyme or dill. Stir everything together until evenly mixed.

5. Assembling and Baking:

Pour the zucchini mixture evenly into the prepared pie crust. Place the pie on the middle rack of the oven and bake for 35-45 minutes. The quiche is done when the top is golden brown and a knife inserted in the center comes out clean.

6. Cooling and Serving:

Remove the quiche from the oven and let it cool slightly—this makes slicing easier. If you like, garnish with fresh dill or parsley before serving. Enjoy your cheesy zucchini quiche warm or at room temperature!

Can I Use Frozen Zucchini for This Quiche?

Yes, you can use frozen zucchini, but be sure to thaw it completely and squeeze out as much moisture as possible before adding it to the filling. This prevents the quiche from becoming watery.

Can I Substitute Milk for Heavy Cream?

Absolutely! Whole milk works well for a lighter version. Avoid skim milk, as it can make the filling too thin. You might also try half-and-half for a balance of creaminess and lower fat.

How Should I Store Leftover Quiche?

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat slices gently in the oven or microwave until warmed through.

Can I Make This Quiche Ahead of Time?

Yes! Prepare the quiche up to a day ahead and refrigerate it before baking. When ready, bake it fresh to preserve the texture and flavor, adding a few extra minutes to the baking time if needed.
