The best part is that I can thank a reader for this one. Kate and I always love reading your comments (and we wish you’d comment more, we love to hear from you!) and we love to click on your profiles in a non-stalker-ish manner and check out your blogs too. I have found SO many cool people and interesting blogs just from looking at the people commenting here. We have such a talented audience! That’s just last week I stumbled upon Susan and her blog MyEyeQ. The first thing that caught my eye was her photography (drool!) and the next thing was a recipe for zucchini quiche. Tis the season for zucchini and I knew I had to try it. I changed the recipe from the original, mostly to accommodate a single 9-inch crust as opposed to 2 8″ ones. My family and assorted taste testers loved this one and I think you will too!
If you have a mandoline or a food processor, then slicing the zucchini will be a cinch and you’ll get perfectly even sized pieces. If you don’t have either, then no worries, just use a knife.
Set those aside and melt some butter in a large skillet. Cook a little garlic and onion (I use red onions for color, but white or yellow work just fine too)
When they’ve softened up a bit, toss in the sliced zucchini and and salt and pepper and cook for a few minutes longer.
You could really use just about any fresh herb in this. I have tons of oregano in my garden so I used that. Basil or thyme would be great too.
Now we can’t have quiche without eggs, right? Pretend there’s 3 in this bowl! I was adjusting as I went and ended up adding an extra one at the end. Beat those up and add a touch of dijon mustard, some red pepper flakes, and the herbs.
Now comes my favorite part of quiche. Cheese. It’s actually my favorite part of any dish that requires cheese. Gruyere is a little pricey but it’s worth it. You could substitute a good Swiss, but try the Gruyere if you can, it’s awesome! It melts beautifully which is why you often see it in fondue and baked pasta dishes and it has a strong enough flavor that it comes through in a dish like this. I also love it when it comes in a fancy paper package. This one says Switzerland and that makes me happy. I’ve been to Switzerland and they have the most beautiful cows I’ve ever seen in my life. So apparently beautiful cows make beautiful cheese.
Mix the egg mixture with the zucchini mixture and pop it all in the pie shell.
Sprinkle a little Parmesan on top (or you could just use a little extra Gruyere). I also sprinkled a few extra pepper flakes on top for color- but be careful if you do that because it might turn out spicier than you expected!
Bake it up in the oven until the top is golden and your house will smell soooo yummy.
Quiche is a great dish because it’s so flexible. You can serve it for breakfast or brunch along-side fruit and sweet rolls, or you can have it for dinner with a salad. It can be served warm or at room temp, or even cold out of the fridge. I actually think this tasted better room temp than it did when it was warm. I like how it sets up once it cools and I could taste all of the flavors better.

Zucchini Cheese Quiche
Equipment
- 1 pie pan
Ingredients
Crust
- 1 ¼ cup all-purpose flour
- ½ teaspoon table salt
- ⅓ cup + 1 tablespoon shortening I prefer butter flavored but either works; look for it in sticks
- ¼ cup ice water
Filling
- 1 lb zucchini thinly sliced (about 3 small-medium zucchini)
- 1 tablespoon butter
- ½ cup red onion diced
- 3 cloves garlic pressed or finely minced
- kosher salt
- black pepper
- 3 eggs
- ½ tablespoon dijon mustard
- 1 ½ tablespoon oregano, fresh, chopped or 1 ½ tsp dry
- ⅛ – ¼ teaspoon red pepper flakes
- ¼ cup grated Parmesan cheese
- 5 ounces gruyere cheese
Instructions
Crust
- Combine flour and salt in a medium-sized bowl. Add shortening in small cubes.
- Cut in shortening (room temperature) until you get pieces that are about pea-sized.
- Start sprinkling the ice water by about a tablespoon at a time over the flour/shortening mixture. Very gently, turn the dough with your fingers so it gets exposed to the water. You’re not mixing, just trying to moisten all of the flour/shortening mixture. Gradually, all of the flour mixture will be moistened. Gently pat the dough into a ball (it should come together easily but not be sticky).
- Wrap in plastic wrap and keep in the fridge until you’re ready to use.
- When ready to use, handle as little as possible according to recipe directions.
Filling
- Preheat oven to 375℉.
- Place rolled out pie crust in a 9″ pie plate and flute edges. Place in fridge until ready to use.
- In a large skillet on the stove-top, melt butter. Add onions and garlic and cook for about 1 minute, stirring frequently. Add sliced zucchini and add a sprinkle of salt (about ½ teaspoon) and a few cracks of black pepper. Cook, stirring occasionally, for 3-4 minutes until zucchini is softened. Remove pan from heat and set aside.
- In a separate bowl lightly beat eggs. Add dijon mustard, oregano, red pepper flakes. Whisk until combined and then gently stir in Gruyere cheese.
- Add egg and cheese mixture to zucchini mixture and toss until combined. Place mixture in prepared pie crust and sprinkle Parmesan cheese on top.
- Bake for 40-50 minutes or until center is set and top is lightly golden. Cool for at least 15 minutes before cutting. Can be served warm, at room temp, or even cold.
Questions & Reviews
Pie Crust Help!
This looks deeelicious! I’ve never made quiche, or pastry and I was looking up the pie crust Recipie to see if I could have a go… But it doesn’t work. So I did a word search in the Recipie index but there are so many I don’t know which is the right one
Can I get directions or the Recipie please, I’m lost, and with no pastry it will just be a yummy omelette
Here you go!
Has anyone made a crustless version of this quiche? Its one of my favorites but I have some gluten sensitive friends coming for Easter.
I had a feeling that this recipe would be good…but I was wrong. It ROCKED! I didn’t have access to Gruyere cheese, so I just used shredded artisan Parmesan cheese blend. I also used a pre-made Pillsbury crust. And it STILL turned out fabulous!!! I TOTALLY recommend this recipe! 🙂
I am a newly married student at BYU-Idaho and your cookbook has changed my life! I love everything in it!!! Thanks for helping me feel like a gourmet chef!! You guys are amazing and I tell everyone how much I love you. 🙂 Because I really do love you!!!!
Made two of these tonight so I have plenty for leftovers. One per the recipe and one substituting Feta for the Gruyere. They are absolute HEAVEN.
This looks very tasty. I want to try it since zucchini is piling up on the counter…only problem is that my husband can’t have cheese so will have to make when he is missing.
ONE MORE PIECE OF PARADISE! LOVED IT!
just popped mine in the oven. Unfortunately, I didn’t have all the ingredients so I’m substituting and I hope it turns out well. I was out of fresh garlic. Hubby doesn’t want the red pepper and all I had was dried Oregano and none of the cheeses it called for so I will have to use cheddar/mozzarella. I’ll let you know how it turns out. I also had to use a store bought pie crust; Marie Callender’s. I LOVE your blog; so fun and inspiring. It temps me to cook more which means I need to learn to shop for better ingredients. Keep up the great work!
