This delicious spaghetti squash pizza is ready in less than an hour. It combines the flavors and cheesiness of pizza with a better-for-you vegetable base.

When my kids ask if we can order pizza and I have spaghetti squash in the house, I ask them if they would like this veggie-based pizza instead. Nine times out of ten, the enthusiastic answer is "Yes!" So this should tell you how good it is. It's genius, really - enjoy all the cheesiness and goodness of pizza but with a vegetable base.
Ingredients
See the recipe card for exact measurements. Here are my comments on some of the ingredients.
- Spaghetti squash: I use a small, 2-pound squash.
- Marinara sauce: I use a sugar-free sauce such as Rao's.
- Cheese: I use shredded part-skim mozzarella.
- Topping: I use pepperoni.
- Grated parmesan: It's best to use finely grated parmesan and not coarsely shredded, although if all you have is shredded, you can use that.
Variations
- You can use different melty cheeses instead of mozzarella. Provolone is a good option.
- You can use whatever toppings you like and enjoy. I like to use pepperoni, but other options include olives, sautéed mushrooms, red onions, and bell peppers.
- Sometimes, I mix a cup of shredded baked chicken breast into the squash.
Instructions
The detailed instructions and step-by-step photos are included in the recipe card. Here's a quick overview.
Cook the squash. You can microwave the squash or bake it. Rake a fork back and forth to remove strands of the flesh, keeping the shells intact.
Mix the strands with marinara sauce and shredded mozzarella, then transfer them back to the shells. Arrange the pepperoni on top and sprinkle the squash halves with the remaining mozzarella and parmesan.
Bake until the cheese is melted and lightly browned, about 15 minutes. Let rest for five minutes before serving.
Recipe Tip
When you rake the squash's flesh to create the strands, work carefully so that the shells remain intact, and leave some flesh in the shells.
But if the shells get torn despite all your best efforts, do not despair. Simply bake the filling in a casserole dish like a square 8-inch baking dish. It won't be as pretty, but it will be just as delicious!
Recipe FAQs
I like to microwave it because it's faster, but baking does yield superior results in terms of texture and flavor. Microwaved squash can be a little mushy.
Theoretically, you could, but I don't think it would be a very pleasant experience. Once baked in the oven, the skin will be tough and dry.
Piercing helps prevent it from exploding in the microwave.
You can keep the leftovers in an airtight container in the fridge for 3-4 days. They keep well! Reheat them covered in the microwave at 50% power or uncovered in a 350°F oven. I don't recommend freezing the leftovers.
Serving Suggestions
I usually serve spaghetti squash pizza as a main course, alongside a simple green vegetable that I can cook in the same 425°F oven, like roasted Brussels sprouts, roasted green beans, or roasted broccolini.
You can also serve it with an easy side salad like arugula salad, cucumber vinegar salad, or cherry tomato salad.
When I serve it as a side dish, I pair this pizza with a main course I can cook in the same oven, like chicken leg quarters, baked salmon, and roasted rack of lamb.

Ingredients
- 2 pounds spaghetti squash
- ½ cup marinara sauce
- 4 ounces part-skim mozzarella - shredded, divided
- Dash sea salt
- Dash black pepper
- 1 ounce pepperoni
- 2 tablespoons parmesan - grated
- 2 tablespoons parsley - chopped
Instructions
- Preheat the oven to 425°F.
- Cook the spaghetti squash in the microwave: wipe the skin clean, pierce it in a few places with a sharp knife, place it on a microwave-safe plate, and microwave on high until tender, for about 5 minutes on each side.
- Allow the cooked squash to rest for 10 minutes until cool enough to handle. Cut it open with a sharp knife. Use a large spoon to discard the pulp and seeds. Rake a fork back and forth to create spaghetti-like strands, placing the strands in a large mixing bowl. Work carefully so that the shells remain intact, and leave some flesh in the shells.
- Add the marinara sauce to the spaghetti squash strands. Mix well to coat. Mix in 2 ounces of the shredded mozzarella.
- Sprinkle the inside of the squash shells with salt and pepper. Transfer the marinara-coated strands back into the shells. Arrange the pepperoni on top and sprinkle the squash with the remaining mozzarella and with parmesan.
- Place the squash shells in a square 8-inch baking dish, or any other baking dish that will hold them snugly. Bake until the cheese is melted and lightly browned, about 15 minutes.
- Remove the pan from the oven. Sprinkle the pizza with parsley. Allow it to cool for about 5 minutes, then serve.
