Have you ever made a spaghetti pie? I hadn't, until now. No pasta or pizza dough here. Just roasted spaghetti squash, eggs, sauce, protein, and herbs.
This is an easy dish to bake and serve, and it can be eaten any time of day. Make it and place it in the refrigerator for a few days. It reheats quickly and stays together. I haven't frozen it and I suspect it would get kind of soggy upon reheat.
My base recipe is vegetarian and free of dairy, but you can add cheese and your favorite protein (besides the eggs). My favorite addition is my cauliflower bolognese sauce on top of the pie as a topping along with grated Parmesan cheese and fresh basil. I added some general measurements for add-ons in the recipe notes.
If you try this recipe, I'd love to hear about your additions or changes. It seems like there's no limit to what you can do with this spaghetti squash recipe.
Preparing spaghetti squash. In the past I've shared photos where I've sliced the squash down the middle the long way and then placed each half face down to bake. This leaves the noodles to steam a bit so they're softer and moister. To get slightly longer spaghetti squash noodles that are not as moist, slice the squash in half crosswise instead of lengthwise. This shortens the baking time and makes it easier to separate the noodles from the outer skin. And to make it easier to slice the squash, place it in the pre-heated oven for a few minutes.

Any thoughts for an egg-free version? I’m getting around it ok with applesauce in baked goods, but doesn’t seem like the best plan in spaghetti 😉
Erica says
Not that I can think of.

So excited to try this! My husband doesn't eat mushrooms. What is a good replacement to try in their place?
Erica says
You can use any ingredients you like, really. You can replace with ground, sautéed meat if you eat meat.

It was delicious! I made it last weekend and I might make it again this weekend.

Ok, squash is baking. Do I use all of the squash (except skin) - stringy stuff and the rest?
Erica says
You can bake the seeds separately (see recipe for pumpkin seeds). The stringy stuff is probably ok in the pie, but up to you.
