Easy Veggie Quiche Recipe
Our Vegetable Quiche proves once again that veggie-based meals can, in fact, be super satisfying. Sure, you can absolutely add in some ham, sausage or bacon if you want. But, we really don’t think you’ll miss the meat amongst all of the cheesy, eggy, flakey crust goodness.
During the summer, this is a great recipe to use up extra garden produce. Or, if you have vegetables in the fridge that are past their prime, chop them up and toss them into a saute pan. This is one of the best vegetable quiche recipes to make when cleaning out the fridge too. Chop 'em up and throw it in!
One fun way to get little ones involved is to make them into mini veggie quiche cups using muffin tins. You can even spray cupcake liners with a little non-stick pan spray and nix the crust to make it easier. We find letting kids get more involved by adding the veggies and cheese helps them try more foods they wouldn’t normally eat!
Ingredients in Vegetable Quiche Recipe
- Pre-Made Pie Crust - you can find this in the refrigerated section at the grocery store. You can also substitute frozen puff pastry or make your own pie shell from scratch.
- Veggies - you can use just one type, or a mixture of a bunch of your favorite veggies. Some suggestions include broccoli, mushrooms, red bell peppers, asparagus and spinach. Make sure to cut any non-leafy veggies into roughly ½” chunks so that they cook evenly. Spinach or kale can just be wilted at the end of cooking.
- Eggs - any type of large eggs will work. You can also substitute half egg whites if you want your quiche to be a little more heart-friendly.
- Shredded Cheese - we recommend using Swiss or cheddar cheese. Feta, goat cheese or mozzarella would also taste great.
- Milk - you want to use either whole milk or 2%.
- Heavy Cream - any type will work.
- Salt and Pepper
- Cayenne Pepper - this is optional but adds a perfect amount of heat.
- Nutmeg - you’d be surprised what a little nutmeg can do to the overall flavor. It goes so well with eggs.
- Dijon Mustard - this is optional, but it adds a great depth of flavor to your filling.
- Avocados and Tomatoes - these are optional topping ideas that add a little freshness and extra flavor.
How to Make Vegetable Quiche
- Prepare pie crust. Roll out pie dough to about ¼” thick and press into a 9-inch pie pan. If using a premade pie crust, remove it from the refrigerator about an hour before you make your quiche so that it warms up to room temperature. Roll out the pie crust as directed on the packaging and arrange in a 9" pie plate. Place in the freezer for a few minutes, just until it is no longer super soft, then pull out and line the inside with aluminum foil. Fill with pie weights or dried beans and bake in a preheated 350 degree oven for about 15 minutes. Remove from the oven, carefully remove the foil and set aside.
- Make the filling. In a saute pan over medium-high heat, cook vegetables until tender, or between 5-10 minutes, depending on the veggies. Season with salt and pepper as desired, then add to the prepared pie crust. Sprinkle half of the cheese on top of the veggies. In a medium-sized mixing bowl, whisk together the eggs, milk, cream, salt, pepper, nutmeg, mustard, and cayenne. Mix until well combined, then pour over the veggies and top with the remaining cheese.
- Bake. Bake the quiche in a preheated oven at 350 degrees for about 30-40 minutes, or until the egg mixture is set in the middle. You can test by gently shaking the pan just a little to see if the middle of the quiche is still runny. If you still aren't sure, a toothpick or knife inserted into the center should come out clean.
- Serve. Once baked, remove from the oven and allow to cool for at least 5 minutes before slicing and serving with sliced avocados and tomatoes. Enjoy!
Best Vegetables For Quiche
- Leftover Stir Fry Vegetables- This recipe is a great way to use up leftover stir fry vegetables. If you have some sitting in your fridge, that are past their prime toss them in here. It's fine that they're already cooked and makes an easy mixed vegetables quiche.
- Peppers- Red Peppers, Green Peppers, Yellow Peppers, and Orange Peppers. Bell peppers work best because they get soft as they cook and have such a milk flavor.
- Mushrooms- These are a fav for sure. They add a real hearty texture. Button mushrooms, portabello mushrooms, just about any kind will do.
- Asparagus- Wash and cut these into ½" chunks. It adds a real springtime vibe to your quiche for sure. We love adding asparagus, especially around Easter or Mother's day.
- Spinach- This adds a ton of color to your quiche and is perfect to add to your quiche recipe when it's a little wilted from the fridge. Just be careful to not add any slimy bits of spinach.
Tips for Veggie Quiche Recipe
- Skip the crust altogether and make a vegetable quiche crustless. Be sure to spray your dish with non-stick cooking spray before adding the filling. It works especially well to use muffin tins for crustless quiche.
- Grease your pie dish with butter, then sprinkle a thin layer of shredded Parmesan cheese over the bottom of the dish. For one 9” quiche you should only need about 2 tablespoons. This adds a fun cheesy flavored crust that will help it stay together when you're eating it.
- If you want to try a different type of gluten-free crust, our Potato Crusted Quiche recipe makes an excellent substitute. It’s also gluten-free, super simple, and really yummy.
Storing, Freezing and Reheating
- Refrigerator - wrap your vegetables quiche with plastic wrap and store in the refrigerator for up to 3 days.
- Freezer - Be sure and cool your quiche completely, then wrap well in plastic wrap, followed by aluminum foil. You can store quiche frozen for up to 3 months.
- Reheating Instructions - In order to reheat a frozen quiche, thaw it in the fridge overnight. Once thawed, the instructions are the same whether it was in the freezer or fridge. Just rewarm in a preheated 325-degree oven until warmed through, or about 20-30 minutes. You may want to cover the crust with aluminum foil part-way through if it begins to brown too much.
