Ingredients You’ll Need
Tip: You’ll find the full list of ingredients and measurements in the recipe card below.

To bring these spaghetti squash pizza bowls to life, here’s everything you’ll need:

2 medium-to-large spaghetti squash (about 5.5 pounds total)
Or substitute with 3 small spaghetti squash
4 teaspoons + 1 tablespoon extra-virgin olive oil, divided
Used for roasting and sautéing
Salt, to taste
Freshly ground black pepper, to taste
4 medium cloves garlic, pressed or minced
6 ounces (about 6 packed cups) baby spinach
⅔ cup (2 ounces) grated Parmesan cheese
2 cups marinara sauce (store-bought or homemade)
8 ounces (2 cups) grated part-skim mozzarella cheese
Chopped fresh basil, for garnish
Pinch of red pepper flakes, optional (for a kick)

These are all everyday ingredients, yet when you put them together, the result is anything but ordinary.

Let’s Get Started

Time to make the magic happen — and don’t worry, it’s easier than it looks. Follow these steps and you’ll be scooping into cheesy, saucy deliciousness in no time.

Preheat the Oven
Start by heating your oven to 400°F (205°C). Line a baking sheet with parchment paper for easier cleanup.
Prep and Roast the Squash
Carefully cut each spaghetti squash in half lengthwise. Scoop out the seeds with a spoon and discard. Drizzle the inside of each half with 4 teaspoons olive oil, and season with salt and pepper. Place them cut-side down on the baking sheet.

Roast for about 40–45 minutes, or until the squash is tender and you can easily shred the flesh with a fork.
Cook the Spinach and Garlic
While the squash is roasting, heat 1 tablespoon olive oil in a large skillet over medium heat. Add the minced garlic and stir until fragrant, about 30 seconds. Toss in the spinach and cook, stirring frequently, until wilted (about 2–3 minutes). Remove from heat and set aside.
Shred the Squash
Once roasted, flip the squash halves over and let them cool slightly. Then, use a fork to gently scrape the inside of the squash, separating it into strands. Leave the strands in the shell — they’ll serve as the base of your pizza bowls.
Layer the Flavor
Stir the cooked spinach mixture into the shredded squash within each shell. Add a sprinkle of Parmesan cheese (about 1 tablespoon per half), then pour in ½ cup marinara sauce per bowl. Top each with ½ cup mozzarella cheese. Add a dash of red pepper flakes if you like a little heat.
Broil to Finish
Return the squash bowls to the oven and broil on high for about 3–5 minutes, or until the cheese is melted, bubbly, and just starting to brown. Keep an eye on them — broiling can go from perfect to burnt quickly!
Garnish and Serve
Once out of the oven, sprinkle with fresh basil, a little extra Parmesan, and serve immediately. They’re hot, gooey, and irresistible!

Servings and Pairing

This recipe makes 4 generous servings — one half of a squash per person. Each bowl is hearty enough to be a standalone meal, but if you’re feeling fancy, here’s what to pair it with:

Perfect Pairings:

A light Caesar salad or arugula salad with lemon vinaigrette
Garlic knots or crusty bread (if carbs aren’t an issue)
A crisp glass of white wine, like Sauvignon Blanc
Or a cold sparkling water with lemon for a refreshing touch

Variations

Want to switch things up? This recipe is super flexible. Try any of these ideas:

Add Protein: Top with cooked Italian sausage, turkey pepperoni, or grilled chicken before adding cheese.
Go Vegan: Use dairy-free cheese and skip the Parmesan or use nutritional yeast instead.
Spice It Up: Add sautéed mushrooms, olives, or jalapeños for extra flavor layers.
Different Sauces: Swap marinara for pesto or even a creamy Alfredo for a whole new vibe.
Mini Pizza Bowls: Use smaller squash and serve them as appetizers.

Storage Tips

Have leftovers? Lucky you — they store and reheat like a dream.

Refrigerate: Let the squash bowls cool completely. Store in an airtight container or wrap each half in foil. Keeps well for up to 4 days.
Reheat: Bake in the oven at 350°F for 10–15 minutes until heated through, or microwave (though it might soften the texture slightly).
Freezing: Not ideal, as spaghetti squash can get watery when thawed, but you can freeze the cooked squash and toppings separately for up to 1 month.
