Spaghetti Squash Quiche is entirely gluten-free and delicious. Roasted spaghetti squash is pressed into a pie plate and baked. The "crust" is then filled with veggies, eggs, and cheese, and then baked again.

In my opinion, the spaghetti squash is the most versatile of all the winter squash. Its flavor is slightly nutty, and its texture isn't at all mushy once cooked.
Spaghetti squash quiche with its spaghetti squash crust is a delicious gluten-free option that adds great flavor and consistency to this breakfast or brunch favorite!

Jump to RecipeWhat ingredients are needed to make spaghetti squash quiche?
- Spaghetti Squash
- Parmesan Cheese

- Cheddar Cheese
- Eggs
- Milk
- Fresh Thyme
- Salt and Pepper
- Olive Oil

Important tips for making spaghetti squash quiche:
- The key to this recipe is to roast the spaghetti squash well in advance of when you're actually ready to assemble the quiche. Once roasted, cool the squash slightly before scraping out its interior "strands".
- Season the strands and press them into the bottom, and up the sides, of a prepared pie pan before it's baked again for a second time.
- You'll notice that after you bake the spaghetti squash "crust", quite a bit of moisture will form on top of the squash.
- Since I was worried that this would prohibit the quiche from setting up as I had hoped, I blotted the top of the "crust" with a few paper towels before I added the vegetable filling and eggs. Don't forget this step!
- I do believe it's an important one that will keep your quiche from having a soggy bottom. And, as we all know, nobody likes a soggy bottom!
How long will it take to make this quiche from start to finish?
Since the spaghetti squash needs to be cooked before it can be used as the crust, this will add approximately 1 extra hour (cooking and cooling) of preparation time, so please plan accordingly.
From start to finish, this spaghetti squash and veggie quiche will take approximately 2 hours.
Can the spaghetti squash be cooked in advance?
YES! Great idea!!
It's a wise choice to cook and cool the spaghetti squash the night before if you don't have the time in the morning to start this recipe from scratch. By cooking the spaghetti squash ahead, in the morning you'll only need to press, fill, and bake the quiche which will shave off a lot of morning prep time.
What are some alternate vegetable suggestions for this recipe?
- Mushrooms
- Zucchini
- Egg Plant
- Avocado

- Green Pepper
- Asparagus

- Brussels Sprouts
- Peas
- Green Beans
- You name it...
Can I omit the bacon and make this a vegetarian quiche?
You sure can!!
Pretend as though bacon was never part of the recipe.
I'm 100% good with that!!
Can ham or sausage be used in place of the bacon?
YUP!!
Make sure the meat you choose to use is fully cooked before adding it to the quiche and you're good to go.
How to make gluten-free spaghetti squash crust quiche:
- Use a sharp knife and carefully cut the squash in half lengthwise.
- Remove the seeds (I find an ice cream scoop works best) and place the squash cut side down on a prepared baking sheet.
- Roast in a 425-degree oven for 40 minutes.
- Cool and then scrape the strands of the squash and place in a large bowl.
- Add the Parmesan cheese, thyme, olive oil, nutmeg, and garlic powder into the squash. Mix well.
- Press the squash mixture evenly into the bottom of a prepared pie pan and up the sides.
- Bake the squash crust for 10-15 minutes.
- Pat with paper towels to remove excess moisture.
- Set aside while preparing the filling.
- Sautée the broccoli and tomatoes in the same pan that the bacon was cooked in.
- Spread the bacon, veggies, and cheese evenly into the pie pan.
- In a large bowl, whisk together the eggs, milk 1 teaspoon salt, and ½ teaspoon pepper.
- Pour the egg mixture into the pie pan and bake for 60-65 minutes until the quiche is set in the center and is golden brown in color.
