A good vegetarian quiche is one of those dishes that feels both comforting and versatile. It’s an ideal choice when you need something hearty yet light, elegant yet unfussy. Whether you’re hosting a brunch, packing lunch for the week, or simply craving something savory and satisfying, this easy vegetarian quiche fits the bill beautifully.
What makes this dish such a go-to favorite is its flexibility. Start with a basic pie crust, homemade or store-bought, and from there, you can build endless flavor combinations. Common additions include spinach, mushrooms, tomatoes, zucchini, onions, and bell peppers, all of which add color and texture. The beauty lies in using what you have on hand or what’s in season, making this quiche a true “clean out the fridge” hero.
The filling comes together quickly. Whisk together eggs, milk or cream, salt, pepper, and perhaps a pinch of nutmeg for a subtle depth. Add cheese like cheddar, feta, Swiss, or goat cheese for extra richness and character. Then fold in the sautéed vegetables before pouring the mixture into the crust and baking until golden and set.
One of the best things about vegetarian quiche is how well it holds up. It can be served warm, at room temperature, or even cold straight from the fridge. That makes it perfect for meal prepping or entertaining, since it can be made ahead and still taste amazing the next day.
Serve it with a simple green salad or a bowl of soup for a complete meal. For brunch, pair it with fresh fruit or a light smoothie. The quiche is both filling and balanced, rich in protein from the eggs and cheese, and packed with fiber from the vegetables.
Whether you’re feeding a crowd or just looking for an easy, meatless option to enjoy during the week, this easy vegetarian quiche delivers every time. It’s proof that with just a few ingredients and a little time, you can make something truly satisfying.

Easy peasy! I threw in some leftover broccoli too. Highly recommend!
Quiche means egg tart in French, right? This recipe ain’t traditional but I still liked it.
This is just a fancy egg pie! Whatever, still tasty!
Quick and easy! Perfect for a brunch with my girls. Everyone loved it.
Can I freeze this or not? Want to make it for later but not sure. Thanks.
Quiche is supposed to have bacon… why no meat in this? Disapointing!
This was so good! I added some mushrooms and it was amazing! Will definitely make again.
Simple and quick. But I forgot tomatos lol. Still tasted good somehow!
Love it! Straightforward and perfect for brunch.
Yum! My kids loved it! Even the spinach, can you believe that? Will share with my neighbors too!
Yummy! 😋 I added some spices and it was lit!
Too much cheese! I prefer less. Just a thought.
Ugh, quiche is overrated. Not for me. 👎
This was super easy and delicious! I added some mushrooms and it turned out great. Will definitely make again!
I question the Swiss cheese, feta is better for quiche. But still a decent recipe.
I followed the recipe but it came out too soggy. Maybe my pie crust was too thick?
Meh, was kinda bland. Needs more spices. I would not recommend it.
Ehh! I dunno, quiche seems kinda fancy for breakfast. I prefer cereal.
Quiche is actually super easy to make, and it can be great for breakfast! I used to prefer cereal too, but now I love mixing it up with something like this.
Fancy? C’mon! It’s just eggs and veggies in a crust. Cereal is for kids! Give it a try, you’ll like it!
Perfect for breakfast! I added some mushrooms and it turned out beautifully. Thank you for sharing!
This quiche was a hit at my brunch! Super easy and delish. Would highly recommend!
Gotta say, I was skeptical about the spinach and cheese combo, but wow! Turns out they work well together. Thanks for sharing!
GREAT RECIPE
Thanks! I can’t wait to try it!
I don’t know if I did something wrong, but my quiche didn’t set. It was a runny mess. So disappointed!
My kids loved it! Finally a recipe they ate without complaining. Thanks for sharing!
That’s awesome! I’m glad to hear your kids liked it. I had the same success with mine!
Really? My kids won’t touch spinach! Maybe I should try making it without the spinach?
This quiche is so easy to make! My kids loved it. Will definitely make again!
I don’t get why people love quiche so much. This was just okay for me. Tasted kinda bland.
1 cup milk? That seems like too much. Should I just use half?
Yummm, I added some feta and it was great! Super tasty and filling.
Feta sounds like a great addition! I’ll definitely try that next time I make this.
I dunno, quiche is just eggs in a pastry. How can it be super tasty? Sounds kinda basic.
Why is there so much cheese? It’s vegetarian not cheesy-pasty!
I love how you can add whatever veggies you like! I used zucchini and mushrooms instead and it turned out great.
Zucchini and mushrooms sound delish! Can’t wait to try it that way.
I tried this but it was too watery :/ Not sure what I did wrong…
This quiche was amazin! So easy to make and taste great! I’m def making this again!
Okay recipe, but why use Swiss cheese? I prefer cheddar! That’s just better.
Honestly, it was okay. Just a quiche with veggies, nothing special.
I think you just didn’t add enough spices! Quiche is all about flavor. I love mine with a little bit of garlic and herbs. You should try that next time!
I don’t like spinach, is there something else I can use? More cheese maybe? Haha.
You could replace the spinach with kale! It’s super yummy and has tons of nutrition too. Just a thought!
More cheese sounds great! But you still need a base, like greens or something, or it might just be cheesy eggs in a crust. Lol.
I tried this recipe but forgot the pie crust. It was messy but still kinda good. Won’t forget next time!
