Broccoli Quiche with a Flaky Crust (No Soggy Bottom)
A good broccoli quiche is one of those rare dishes that feels special enough for Sunday brunch but simple enough for a Tuesday dinner. The filling sets up silky and rich, the broccoli stays bright green, and the crust shatters under your fork.
It avoids the two things that can sink a quiche: a soggy bottom and a watery, eggy texture. A quick blind bake, a brief sauté for the vegetables, and a moderate oven do the work. You pull it out when the center still has a gentle wobble, and by the time it rests, it is custardy and sliceable.
Why This Quiche Stays in the Rotation
I have made plenty of quiches that came out with scrambled-egg fillings and doughy crusts. This version gets it right by parcooking the crust until it is pale gold, then baking the custard at a temperature low enough to set it without puffing and cracking.
The broccoli goes in raw after a quick toss in a hot pan with onion and butter, so it softens just enough in the oven without turning to mush. Even my vegetable-averse niece asks for a second slice, and that is the real win.
Ingredients
- 1 unbaked 9-inch pie crust: store-bought or homemade, not deep-dish
- 1 tbsp unsalted butter
- 1 small yellow onion, diced
- 2 cups small broccoli florets: cut to bite-size pieces about 1 inch
- 4 large eggs
- 1 cup half-and-half: or a mix of equal parts whole milk and heavy cream
- 1 tsp Dijon mustard
- ½ tsp kosher salt
- ¼ tsp black pepper
- ¼ tsp freshly grated nutmeg
- 1 cup shredded sharp cheddar cheese: about 4 oz
Variations / Substitutions
- Dairy-free: swap the half-and-half for full-fat oat milk and use a plant-based buttery spread for the sauté; choose a vegan cheddar-style shred.
- Herb swap: replace the nutmeg with 1 tsp chopped fresh thyme or chives for a more savory note.
- Cheese change: Gruyère, fontina, or smoked Gouda all work nicely in place of cheddar.
- Add protein: fold in ½ cup diced cooked ham or crumbled bacon with the cheese.

How to Make Broccoli Quiche
Step 1: Parbake the Crust
Heat the oven to 375°F (190°C) with a rack in the lower third. Roll the pie dough into a 9-inch pie plate (not deep-dish), crimp the edges, and prick the bottom all over with a fork. Line it with parchment paper or foil and fill with pie weights or dried beans.
Slide it onto the oven rack and bake for 15 minutes. The edges should look set and just beginning to color. Lift out the parchment and weights, then return the crust to the oven for another 5 minutes until the bottom looks dry and pale gold. That extra time without the weights seals the surface so the custard won’t soak in later.
Step 2: Sauté the Broccoli and Onion
While the crust blind bakes, melt the 1 tbsp butter in a skillet over medium heat. Add the diced onion and cook for about 3 minutes, until it softens and turns translucent. Toss in the 2 cups broccoli florets and a small pinch of salt, then cook for 2 minutes more, stirring once or twice.
You are not trying to brown anything here. The broccoli should turn a brighter green and lose its raw crunch, but stay firm. Take the pan off the heat and let it cool for a minute while you mix the custard.
Step 3: Whisk the Custard
In a large bowl or a spouted measuring cup, whisk together the 4 eggs, 1 cup half-and-half, 1 tsp Dijon mustard, ½ tsp kosher salt, ¼ tsp pepper, and the ¼ tsp nutmeg. Whisk until the mixture is smooth and homogenous with no streaks of egg white, about 30 seconds. A slightly frothy top is fine; you are not trying to whip air into it.
Step 4: Assemble the Quiche
Turn the oven down to 350°F (177°C). Scatter half of the shredded cheddar over the bottom of the warm parbaked crust. Spoon the broccoli and onion mixture evenly across the cheese, then top with the remaining cheddar. Slowly pour the custard over everything, letting it settle into the gaps.
The cheese acts as a barrier that keeps the crust crisp. If the custard comes close to the top edge of the crust, stop pouring; a full shell can spill in the oven. A little leftover custard is fine to discard.
Step 5: Bake Until Set
Place the pie plate on a baking sheet (it catches any drips) and set it on the lower rack. Bake at 350°F (177°C) for 35 to 40 minutes. Start checking at 35 minutes: the edges should be puffed and golden, and the center should still have a slight jiggle when you nudge the pan.
A fully firm center means the quiche is overbaked and can turn watery as it cools. The residual heat will finish the setting outside the oven.
Step 6: Cool and Slice
Pull the quiche out and let it cool on a wire rack for at least 10 minutes. That short rest lets the custard firm up enough to cut clean slices. Run a thin knife around the edge of the crust, then slice and serve while still warm. The first piece may be a little soft at the bottom, but each next one holds its shape better.
A Few Notes for the Best Quiche
- Use a metal or glass pie plate, not ceramic or deep-dish. The thinner material conducts heat faster, which helps crisp the bottom crust.
- Weigh the crust well: during the blind bake. Push the parchment snug into the corners so the sides don’t slump, and use enough weights to cover the entire bottom.
- Let the broccoli cool a bit: before adding it to the shell. Hot vegetables can start cooking the egg and give you a grainy texture.
- Overbaking is the most common misstep.: Pull the quiche when the center still wobbles like set Jell-O, not liquid, and it will finish perfectly on the counter.
Storing Leftover Quiche
- Refrigerate: cover leftover quiche tightly with plastic wrap or foil and store for up to 4 days. The crust will soften slightly, which is normal.
- Reheating: place slices on a baking sheet in a 300°F (150°C) oven for 10 to 12 minutes until warmed through. This re-crisps the bottom better than a microwave.
What to Serve with Broccoli Quiche
A peppery arugula salad with lemon vinaigrette cuts through the richness of the custard and cheese. Roasted asparagus or a simple tomato and cucumber salad both work for a lighter side. For a brunch spread, add fresh fruit and a basket of flaky biscuits.
Frequently Asked Questions
Can I use frozen broccoli?
Yes, but thaw it first and press out as much water as you can with a clean towel. Skip the sauté step and stir it into the onion off the heat, then proceed.
Can I make this quiche ahead of time?
Bake and cool it completely, then refrigerate overnight. Serve cold or reheat slices in a 300°F oven. The crust stays flakier if you reheat rather than serve straight from the fridge.
Why did my quiche puff up and then sink?
The oven was likely too hot or the quiche baked too long, causing the eggs to soufflé and then collapse. Use an oven thermometer if you are unsure of your dial, and trust the jiggle test.
Can I add other vegetables?
Mushrooms, thinly sliced bell peppers, or blanched spinach all work well. Just cook them first to remove moisture so the quiche doesn’t turn watery.

- In a bowl, whisk together eggs, half-and-half, Dijon, salt, pepper, and nutmeg until smooth.
- Lower oven to 350°F (177°C). Sprinkle half the cheese into the warm crust, spoon broccoli mixture over it, top with remaining cheese, and slowly pour in the custard.
- Place quiche on a baking sheet and bake 35 to 40 minutes until edges are golden and the center still jiggles slightly.
