Ingredients
For this quiche I rely on a few key players: a buttery short‑crust base that stays crisp, a custard that stays tender, and fresh garden zucchini that adds moisture without sogginess. The cheeses (sharp cheddar and creamy Gruyère) give depth, while herbs brighten every bite. A splash of lemon zest ties the flavors together and prevents the custard from feeling too rich.
Crust
- 1 1/4 cups all‑purpose flour
- 1/4 cup cold unsalted butter, cubed
- 1/2 teaspoon salt
- 3 tablespoons ice‑cold water
Filling
- 2 medium zucchini, thinly sliced (about 2 cups)
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 4 large eggs
- 1 cup heavy cream
- 1/2 cup whole milk
- 1 cup shredded sharp cheddar cheese
- 1/2 cup shredded Gruyère cheese
Seasonings & Garnish
- 1 tablespoon fresh dill, chopped
- 1 tablespoon fresh chives, sliced
- Zest of 1 lemon
- Salt and freshly ground black pepper, to taste
The flour and butter create a flaky, buttery shell that holds up to the moist filling. Zucchini contributes a gentle crunch and a hint of sweetness, while the onion and garlic form a savory base. The blend of cheddar and Gruyère supplies sharpness and nutty depth, and the herbs plus lemon zest brighten the custard, preventing it from feeling heavy. Together, these ingredients produce a balanced, crowd‑pleasing quiche.
Step-by-Step Instructions
Preparing the Crust
In a food processor pulse the flour, cold butter, and salt until the mixture resembles coarse crumbs. Drizzle the ice‑cold water over the crumbs and pulse a few more times until the dough just comes together. Shape into a disk, wrap in plastic, and chill for 15 minutes. This resting period keeps the butter firm, ensuring a flaky crust.
Blind‑Baking the Shell
- Roll Out. On a lightly floured surface roll the dough to a 12‑inch circle. Transfer to a 9‑inch pie dish, gently pressing into the corners. Trim excess dough and prick the base with a fork.
- Chill Again. Refrigerate the assembled crust for 10 minutes. This prevents shrinkage during baking.
- Line & Weigh. Line the crust with parchment paper and fill with pie weights or dried beans. Bake at 375°F (190°C) for 12‑15 minutes until the edges are lightly golden.
- Remove Weights. Carefully lift the parchment and weights; bake for an additional 5 minutes until the bottom looks set but not browned. Set aside to cool while you prepare the filling.
Preparing the Filling
Heat a large skillet over medium heat, add a drizzle of olive oil, then sauté the onion until translucent (about 3 minutes). Add the garlic and sliced zucchini, cooking for another 4‑5 minutes until just softened. Season with a pinch of salt and pepper; this step removes excess moisture and concentrates flavor.
Making the Custard
- Whisk Eggs. In a large bowl, whisk the eggs until pale. This incorporates air, giving the custard a light texture.
- Add Dairy. Slowly whisk in the heavy cream, milk, and lemon zest. The gradual addition prevents curdling and ensures a smooth mixture.
- Incorporate Cheese & Herbs. Stir in the shredded cheddar, Gruyère, dill, and chives. Season with salt and pepper; the cheese will add its own saltiness, so taste before adding more.
Assembling & Baking
Spread the sautéed zucchini mixture evenly over the pre‑baked crust. Pour the custard over the vegetables, allowing it to settle naturally. Bake at 375°F for 30‑35 minutes, or until the center is just set and a golden crust forms around the edges. A gentle jiggle in the center indicates perfect doneness. Let the quiche rest for 10 minutes before slicing to let the custard firm up.
Tips & Tricks
Perfecting the Recipe
Dry the Zucchini. After slicing, sprinkle the zucchini with a little salt and let sit for 5 minutes, then pat dry. This removes excess water that could sog the crust.
Use Cold Butter. Keep the butter chilled until it hits the flour. Cold butter creates steam pockets, resulting in a flakier crust.
Don’t Over‑Mix the Dough. Mix just until the dough comes together; over‑mixing develops gluten, leading to a tough crust.
Check for Doneness. Insert a knife near the center; it should come out clean but the custard will still have a slight wobble.
Flavor Enhancements
Add a tablespoon of grated Parmesan to the custard for extra umami. A pinch of smoked paprika sprinkled on top before baking introduces a subtle smoky depth. Finish with a drizzle of truffle oil right after it comes out of the oven for an upscale twist.
Common Mistakes to Avoid
Avoid baking the quiche uncovered for the entire time; the top can brown too quickly, leaving the center undercooked. Also, never skip the resting period after baking—cutting too early releases the custard’s steam, making the slice soggy.
Pro Tips
Use a Light‑Colored Pie Dish. It helps you monitor the crust’s color without the metal darkening the edges.
Pre‑heat the Oven. A fully heated oven ensures the custard sets quickly, preventing a rubbery texture.
Cool on a Wire Rack. This prevents steam from collecting under the crust, keeping it crisp.
Season in Layers. Lightly salt the zucchini, then season the custard separately; layered seasoning builds depth.
Variations
Ingredient Swaps
Swap zucchini for thinly sliced yellow squash or even thin asparagus spears for a slightly sweeter profile. Replace cheddar with smoked gouda for a richer, smoky bite, or use feta for a tangy Mediterranean twist. For a dairy‑free version, use coconut cream and a blend of dairy‑free cheeses.
Dietary Adjustments
To make the crust gluten‑free, substitute the flour with a 1‑to‑1 gluten‑free blend that contains xanthan gum. For a lower‑calorie quiche, replace half the heavy cream with low‑fat Greek yogurt and use reduced‑fat cheese. Vegans can substitute the eggs with a chickpea flour “egg” mixture and use plant‑based cream.
Serving Suggestions
Pair the quiche with a simple arugula salad dressed in lemon vinaigrette, or serve alongside toasted sourdough and a dollop of herbed ricotta. A glass of chilled sparkling rosé or freshly brewed herbal tea complements the bright flavors beautifully.
Storage Info
Leftover Storage
Allow the quiche to cool completely, then slice and place the pieces in an airtight container. Refrigerate for up to 4 days. For longer keeping, wrap each slice tightly in plastic wrap, then foil, and freeze for up to 3 months. Proper sealing prevents freezer burn and keeps the crust from becoming soggy.
Reheating Instructions
Reheat slices in a pre‑heated 350°F oven for 12‑15 minutes, covered with foil to retain moisture. For a quicker option, microwave on medium power for 1‑2 minutes, adding a splash of milk to keep the custard creamy. Avoid high heat, which can dry out the crust.
