Today’s recipe is a roasted summer vegetable quiche, also known as your new throw-all-your-leftovers-into-a-one-dish meal. This is the no-frills, adapt-as-you-wish type of dish that you can enjoy as breakfast, lunch, or dinner. Truly, if it gets any simpler than this, I don’t want to know.
This roasted summer vegetable quiche came out of a desire to use up all of my fresh produce. All summer long we have subscribed to a farmer’s market basket, and as a result, our fridge has been stocked with some seriously random (albeit delicious) produce. Some weeks I’d have a baby eggplant, a bag of okra, a handful of greens, and a pint of tomatoes. Other weeks they’d deliver me a Ziploc full of banana peppers, three giant zucchini, and fresh oregano. At the end of the week, I’d scrape together all the leftovers in my fridge and scour the Internet for a clue on what to do with them.
This roasted summer vegetable quiche is the answer to all those leftovers. Nearly any forgotten tomato, chicken breast, or leftover sausage link would find a home nestled inside a buttery, flaky pie crust. If you’re in a dinnertime rut or just need to clean your fridge out, I really think that quiche is the answer!
Making the Quiche
To make this roasted summer vegetable quiche, we start with the crust. I’ve switched out my trusty, all-time favorite pie crust for an all-butter pastry. You can make this ahead of time, storing in the fridge or freezer prior to use. If you use a tart dish like I did, you’ll want to make sure you roll your dough out large enough to build the edge of the crust up an inch out of the pan. I find that pie dough shrinks pretty easily, particularly when using glass or ceramic dishes like I did. Fit the dough into the pan and par-bake until the crust is set and ready to receive the filling.
The filling is just about as easy as it sounds! The eggs and dairy serve as the glue, holding together all the little morsels of savory veggies and meats your heart desires. Whisk four eggs with one cup of milk, salt and pepper, and a little bit of seasoning as well. I used cheddar and parmesan for my quiche, but you can really use whatever kind of melted shredded goodness you have on hand. Goat cheese, feta, and mozzarella would be killer here as well, just keep your proportions true to the original recipe and you’ll be in good shape.
For this roasted summer vegetable quiche, I included 2 cups of cooked veggies. You can use 2 cups of just about any filling your heart desires, but it is important that it’s already been cooked. Vegetables and meats will often release a whole lot of juices which could attribute to a watery or undercooked mess. For convenience, I’ve given instructions on how to roast a pan of summer veggies below.
Bake the quiche in the oven until the crust and filling have begun to bronze. Serve warm with a fresh salad or even just on it’s own! This roasted summer vegetable quiche should be as easy to serve as it is to make.

Roasted Summer Vegetable Quiche
This roasted summer vegetable quiche is filled with fresh summer veggies, melty cheese, and is served in a flaky all-butter pie crust. Substitute in your favorite filling options in this seriously adaptable dish!
- Prep Time: 35
- Cook Time: 35
- Total Time: 1 hour 10 minutes
- Yield: 12
- Category: Lunch
- Cuisine: French
For the pie dough:
- 2–1/2 cups (350 gm) all-purpose flour
- 1 tablespoon sugar
- 1 teaspoon salt
- 1 cup (230 gm) unsalted butter, cold and chopped
- ½ cup ice water, plus more as needed
For the quiche:
- 1 cup (240 gm) milk
- 4 large eggs, plus one extra for pie wash
- ½ teaspoon garlic powder
- ¾ teaspoon salt
- ½ teaspoon pepper
- ½ cup grated parmesan
- 2 cups roasted vegetables (see notes)
- ½ cup shredded cheddar cheese
To make the pie dough:
- Stir the flour, sugar and salt together. Use a pastry cutter or the backs of two forks to cut in the butter until there are pea-sized clumps throughout. Add about 6 tablespoons of the ice water into the flour mixture and begin to stir together. It will likely be dry and require more ice water, so keep adding water 2 tablespoons at a time until a shaggy dough comes together. Dump the mixture out on the counter and use your hands to form the dough into one ball. It should come together as a dough without feeling wet or too tacky. Cut the ball in half and flatten each half into a disk. Wrap each with plastic wrap and store in the fridge for at least an hour or up to a week. You will only need one half of the dough for this quiche. The other can be wrapped in foil and frozen for up to two months.
- To prep the quiche:
- Preheat the oven to 375 degrees. Use a floured rolling pin to roll the dough out onto a floured work surface into a round of dough about an inch and a half wider on all sides than your 9” tart dish. Roll the dough back onto the rolling pin and the transfer it to the dish, unrolling as you go. Gently work the dough into the edges of the dish and trim off any excess dough, leaving about an inch of excess hanging on all sides. Fold the dough under itself and gently crimp the edges into the dish, allowing the top of the dough to extend about ¾-1” above the lip of the dish. This will help keep your crust tall even after baking. If your dough has gotten soft or warm while rolling it out, place it in the freezer for 5-10 minutes to chill up again.
- When ready to bake, place a crinkled sheet of parchment paper into the bottom of the crust and fill it with pie weights or uncooked dry beans. Bake in the preheated oven about 10 minutes, then remove the paper and weights and bake for an additional 5-10 minutes, or until the bottom of the crust doesn’t look too wet and soggy. While the crust is baking, begin to assemble your filling.
- Whisk together the milk, 4 eggs, garlic powder, salt and pepper. When the crust is finished baking, crack your additional egg in a separate bowl and brush a thin layer of egg white over the bottom of the crust. This will help to keep the crust from becoming soggy. Sprinkle the parmesan evenly over the crust and then spread out the roasted veggies. Sprinkle on the cheddar cheese and then carefully pour the egg mixture into the dish. Be careful to not overflow the tart or the eggs could run over the edge of the crust and into the bottom of your dish. Whisk together the egg from the egg wash and use a pastry brush to brush a thin layer over the exposed crust. Bake in the preheated oven for about 35 minutes or until the top is golden and the center is no longer jiggly. Serve warm or reheat individual slices in the toaster oven!
- To roast your own veggies at home, cut a mixture of vegetables (I use eggplant, tomatoes, onion, bell peppers, and squash) into ½” sized pieces. You’ll need about 6 cups fresh vegetables to make about 2 cups roasted vegetables. Toss the chopped veggies with 3 tablespoons of olive oil on a large rimmed sheet pan. Sprinkle with salt and pepper and roast at 420 for about 20-25 minutes, tossing every 8 minutes or so, until the vegetables are tender and beginning to brown around the edges. You can make these in advance and store in the fridge until ready to use in your quiche!
- As an alternate to the pie wash, you can reserve a small bit of egg white from one of the 4 eggs for the filling. Brush this over the bottom of the quiche and then add the remainder to the filling mixture.
