Why We Love This Recipe For Easy Veggie Quiche

This vegetable quiche is the perfect elegant veggie-packed recipe for breakfast, brunch, or even dinner. 25 years ago I made several quiches a week as part of my job working in a restaurant kitchen and bed and breakfast. Through trial and error I perfected my quiche making skills and honed the right ratios for perfectly cooked quiche.

Along with Veggie Strata, quiche remains one of my favorite favorite classic main courses to serve for company and are easily customizable for whatever veggies you happen to have on hand. They are great when made ahead and can easily be made in multiples with various fillings. I like to make one of my vegetarian quiche recipes (like this veggie quiche today) and one with meat, such as sausage or ham. That way everyone can have just what they like. Plus you can even freeze them!

Our tips today will include using frozen crust (and tips on how to make one from scratch if desired), plus time saving shortcuts like using pre-shredded cheese, and steaming the veggies in the microwave! We’ll walk you through all the steps below.

Ingredients for this Vegetable Quiche Recipe

  • Frozen Pie Shell – We are all about helping busy families cook delicious meals, so we know that sometimes relying on high-quality, convenience items is essential. That’s why we used frozen pie shells for this vegetable quiche recipe. Our favorite is Wholly Wholesome. (Not a sponsored link, I just love them!) They make pie shells that are traditional, gluten-free, and whole wheat. And all three are delicious and bake perfectly every time! But if you have another brand you prefer, that is fine too. You can also make your pie crust from scratch or use refrigerated pie dough. Follow our tips here.
  • Eggs – The eggs are one of the main ingredients here and are a great source of protein, vitamins, and nutrients. One large egg has 6 grams of protein and just 78 calories making it an excellent choice as part of a healthy filling brunch. I have tested this recipe with a blend of egg whites and whole eggs to shave off some of the calories. Feel free to sub 2 whites per 1 whole egg if you’d like to do the same.
  • Vegetables: Mushroom, Bell Pepper, Broccoli – We used mushrooms, green and red bell peppers and broccoli. I have also made this with zucchini and asparagus and it works really well. Really any combination of veggies that you like will work but check our pro tip below for more details on making sure they will be tender.
  • Shredded Cheese – Shredded cheddar, Fontina, Gruyere, or Swiss can be used in the egg mixture of this traditional recipe. I used pre-shredded cheese to make this as easy as possible. Like choosing your own veggie mixture, this is how you can really customize this vegetable quiche recipe. So if you’d prefer to use creamy goat cheese or feta that would be delicious as well. You’ll want 6 ounces total of whichever cheese (or blend of cheese) you choose.
  • Half-And-Half – To make the filling I used half and half. If you’d like to lower the calories of this dish, even more, feel free to use low-fat (1%) milk or even unsweeneded plain almond milk.
  • Additional Seasoning – To season egg dishes, I like to use either a small amount of nutmeg (a classic french choice) or tarragon. Either is best when used in a small amount. You’ll also need salt, pepper, garlic powder and Dijon mustard for seasoning. Feel free to add a little hot sauce, Tabasco or red pepper for a tiny bit of spice.

Chef Katie’s Pro Tip: The veggies are steamed before adding to the quiche filling. This helps them get tender. Otherwise, the vegetables will be crunchy and a little raw. Keep in mind, some veggies don’t need to be steamed, such as green onion, frozen-thawed veggies, or those from a can or jar (like artichoke hearts or roasted red peppers.) Or you can use leftover cooked or roasted vegetables. Harder vegetables, such as potatoes or carrots may need to be cut into smaller pieces or cooked for slightly longer to soften them before they are added.

How To Make Veggie Quiche

vegetable quiche steps 1 and 2

Step 1: Preheat Oven

Preheat the oven to 375°F and arrange the oven rack to the lower third of the oven. One of the keys to great texture for this veggie quiche recipe is cooking it on a lower rack in the oven. Baking it in the bottom of the oven will help the crust set up on the bottom. No blind baking is required!

Step 2: Steam Vegetables

In a microwave-safe bowl, combine mixed chopped vegetables and ¼ cup of water. Cover with a layer of parchment and plastic wrap. Microwave on high for 4 minutes. Carefully remove the cover and drain the veggies in a fine-mesh sieve. This is important to prevent a runny quiche. Let the veggies cool while you prepare the egg mixture.

Step 3: Prepare Filling

In a large bowl, whisk eggs, half-and-half, mustard, salt, pepper, garlic powder, and nutmeg. Stir in the veggies and 1 cup of cheese.

Step 4: Assemble Vegetable Quiche

Pour the egg mixture into the crust. Top with the remaining cheese.

Step 5: Bake

Transfer the quiche to a baking sheet and place it on the rack in the lower third of the oven. Bake until the center of the quiche is lightly puffed, and the crust is golden brown about 40-50 minutes. Allow the tart to cool for 30 minutes before slicing and serving.

To Use A Homemade Pie Crust

If using a homemade pie crust, our favorite pie dough recipe is the All-Butter Crust from King Arthur Flour. But more importantly, if using this from-scratch pie dough, you will want to “blind bake” the shell first. The crust takes a little longer when made from scratch. If you do not blind bake it, the filling will be overbaked by the time the crust is flaky and golden brown.

To blind bake, follow the below steps:

  1. Lay the pie dough in the pie dish and crimp as desired. Chill for several minutes to firm up the crust if it is very soft.
  2. Place a layer of parchment over the raw pie crust and fill with pie weights or dried beans, and bake in a 375°F oven for 20 minutes. 
  3. Remove the weights and bake your homemade crust for an additional 5 to 10 minutes until the bottom of the crust is crisp. 

Then pour egg mixture in, top with cheese and bake the quiche as directed. If the outer crust darkens too much before the filling sets, use a pie shield or foil around the crust only to prevent it from over-browning. 

Tip: homemade 9-inch pie plates are larger than disposable frozen pie plates so you will want to add ½ cup of additional veggies and 2 more eggs to make more filling. 

Vegetarian Quiche Recipe Variations

  • This recipe can be used as a master recipe of sorts. Think of it as many vegetable quiche recipes in one! You can start by using one vegetable only such broccoli or spinach. Or try out our Mushroom Quiche which is an adaptation of this veggie quiche recipe!
  • Instead of microwaving or steaming the veggies, saute them in a large skillet over medium-heat with butter or olive oil. We highly recommend this if using onions as they taste so much better when cooked in fat!
  • Use another type of cheese to change the flavor of this savory tart. We love the classic taste of cheddar or Swiss as well as goat cheese or feta. We even like a blend!
  • Try using puff pastry instead of the pie shell for a quick and easy gourmet crust.
  • For a shortcut, you can skip cooking the veggies! Use frozen and thawed vegetables (chopped broccoli and spinach work beautifully. (Just make sure they are well-drained.) Canned or jarred veggies such as roasted red peppers or artichoke hearts also work well. Some veggies, such as scallions and green onions or cherry tomatoes, do not need to be steamed first. 
  • One combo that’s an all-time favorite is to use 2 ½ cups sauteed mushrooms and Gruyere cheese or Swiss cheese. 
  • Add in fresh chopped herbs for a lovely addition to this easy vegetable quiche recipe. Try 2 teaspoons of chopped dill or ¾ teaspoon of chopped rosemary.

How to Store Vegetarian Quiche

How To Freeze

The quiche can be baked and cooled. Then wrap the quiche in the pie pan and freeze for one month. Defrost the vegetable quiche in the refrigerator for at least 24 hours. Then follow reheating instructions.

How To Reheat The Vegetable Quiche

To reheat, place the quiche in the center of the oven set at 350°F. Bake until the center of the quiche registers 160°F when checked with an instant-read thermometer. This takes about 35 minutes. Cover with a sheet of foil if browning too much.

Veggie Quiche Recipe FAQs

What is the secret to good quiche?

Whipping up a delicious vegetable quiche isn’t complicated. However, there are a few tips and tricks you can use to ensure your savory tart comes out perfect every time. First, season. Be sure to use enough seasoning for the number of ingredients to ensure the dish is perfectly flavored.

Second, be sure to fill the shell to the top. If you’re worried about spills, place the quiche on a baking sheet to catch any overage that may occur.

And last but not least, bake the tart in the bottom third of the oven; baking this close to the heat source will prevent the crust from getting soggy.

Should You Prebake or Blind Bake Quiche Crust?

Yes and no. If you are making your crust from scratch, then yes you do need to blind bake the crust. I spoke with the experts at King Arthur Flour, and they explained that the cold quiche filling insulates the pastry and prevents the bottom crust from cooking fast enough to set up before the butter melts. This makes the butter melt out of the pastry causing the bottom crust to get soggy and greasy. Moreover, the upper edge of the crust will not bake before the egg custard sets up and will be pale and wan.

But when using frozen pie shells, it is not necessary to blind bake the crust. I have tested this recipe both with blind baking the frozen pie shell and straight from the freezer and both work well. I spoke with the baking experts at Wholly Wholesome and they agreed that it is not necessary to blind bake a frozen shell. If you do decide to blind bake your frozen pie shell, make sure to use a pie shield to keep the upper crust from getting burnt. 

Can I make this into a crustless quiche?

You can! Grease your pie plate with butter before adding the quiche filling and top with the cheese. Then bake at 350 degrees F until the center is puffed and set-up, 40 to 45 minutes.

Should you cook veggies before putting in quiche?

For best results, cook your vegetables before adding them to the quiche filling so they will be tender and prevent them from letting off excess moisture. Some veggies, such as scallions, green onions, cherry tomatoes and other tender vegetable do not need to be cooked first. You can also use thawed frozen vegetables in your quiche filling without cooking them first.

Why does my quiche always have a soggy bottom?

Quiche crust can be soggy because cold quiche filling insulates the bottom of the pie crust. This keeps it at a low temperature so it doesn’t crisp up making it soggy and greasy. To prevent this, we use frozen pie shells baked on the bottom rack. If using a homemade crust we suggest blind baking the crust before adding your filling to keep it from getting soggy.

  • 5 large eggs
  • ½ cup half and half or low fat milk
  • 2 teaspoons Dijon mustard
  • ¾ teaspoon salt

  • ¼ teaspoon ground pepper or white pepper
  • Pinch nutmeg or dried tarragon
  • 1 ½ cups freshly shredded cheese such as cheddar, Fontina, Gruyere or Swiss, divided (6 oz)

  1. Arrange oven rack in the lower third of the oven. Preheat oven to 375 degrees F. 
  2. Combine veggies and ¼ cup water in a microwave safe bowl. Cover with a layer of parchment and plastic wrap. Microwave on high for 4 minutes. Carefully remove the cover (watch for steam) and drain the veggies in a fine mesh sieve. 
  3. Whisk eggs, half and half, mustard, salt, garlic powder, pepper and nutmeg (or tarragon) in a large bowl. Stir in the veggies and 1 cup cheese.

Recipe Notes

  • We like Wholly Wholesome frozen pie shells for a quick and delicious quiche. Fill and bake them while they are still frozen.
  • You can also use homemade pie crust. Our favorite pie dough recipe is this All Butter Crust from King Arthur Flour. If using homemade pie dough, you will want to “blind bake” the shell first for 20 minutes with a layer of parchment plus pie weights or dried beans, then remove the weights and bake again for 5 to 10 minutes to crisp the bottom of the crust. Then fill and bake the quiche as directed. If the outer crust darkens too much before the filling sets, use a pie shield or foil around the crust only to prevent it from over browning.
  • Note: homemade 9-inch pie plates are larger than disposable frozen pie plates so you will want to add ½ cup additional veggies and 2 more eggs to make more filling. 
  • Nutritional values are based on using half and half, but if you use low fat milk instead the calories drop to 358 per slice.
  • To freeze: Allow baked quiche to completely cool, wrap in plastic wrap then foil, and freeze for 2 months. When ready to enjoy, defrost in the fridge for at least 24 hours then follow reheating instructions. Or bake from frozen at 325 (with a pie shield to prevent the shell from over-browning) for 1 hour or until it reaches 160 degrees F in the center when tested with an instant-read thermomter.
  • To reheat: place the quiche in the center of the oven set at 350°F. Bake until the center of the quiche registers 160°F when checked with an instant read thermometer. This takes about 35 minutes. Cover with a sheet of foil if browning too much.
