Spaghetti Squash With Marinara – A Cozy, Satisfying Classic
Spaghetti squash with marinara is the kind of meal that feels comforting without weighing you down. You still get that twirlable, saucy experience, but with naturally sweet, tender strands of squash standing in for pasta. It’s simple, budget-friendly, and great for weeknights.
The best part? You can make it as easy or as fancy as you want, depending on your sauce and toppings. If you’re looking for a no-fuss, feel-good dinner, this is it.

Ingredients
Method
- Preheat the oven. Set your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
- Prep the squash. Carefully cut the spaghetti squash in half lengthwise. Scoop out the seeds with a spoon. Drizzle the cut sides with olive oil and season with salt and pepper.
- Roast cut-side down. Place the squash halves cut-side down on the baking sheet. Roast for 35–45 minutes, depending on size, until the flesh is tender and strands pull away easily with a fork.
- Warm the marinara. While the squash roasts, heat your marinara in a saucepan over medium heat. If you like, sauté the minced garlic in a little olive oil first, then add the sauce and Italian seasoning. Simmer for 10–15 minutes to deepen the flavor.
- Shred the squash. When the squash is done, let it cool for a few minutes. Use a fork to scrape the flesh into strands, leaving some structure in the shell if you want to serve it “boat-style.” Taste and adjust salt and pepper.
- Combine and heat through. Add the strands to the saucepan of marinara and toss gently, or spoon warmed sauce over the squash in its shell. Heat until everything is nicely coated and hot.
- Finish and serve. Top with chopped basil or parsley. Add grated Parmesan and a pinch of red pepper flakes if you like. Serve right away while it’s steamy and fragrant.

This dish gives you the familiar joy of spaghetti and marinara with a lighter, veggie-forward twist.
The squash roasts into golden, slightly caramelized strands that hold onto sauce surprisingly well. It’s adaptable too—use jarred marinara for speed or simmer your own if you have time. Best of all, it’s naturally gluten-free and easy to make dairy-free, yet still feels hearty and satisfying.
What You’ll Need
- 1 medium spaghetti squash (about 2.5–3.5 pounds)
- 2 tablespoons olive oil
- Salt and black pepper, to taste
- 2 to 3 cups marinara sauce (homemade or your favorite jarred sauce)
- 2 cloves garlic, minced (optional, for extra flavor)
- 1 teaspoon dried Italian seasoning or dried oregano (optional)
- Fresh basil or parsley, chopped, for garnish
- Grated Parmesan or Pecorino Romano (optional)
- Red pepper flakes (optional, for heat)

Keeping It Fresh
Leftovers store well and actually taste great the next day. Transfer any extra squash and sauce to an airtight container and refrigerate for up to 4 days. Reheat gently on the stovetop over low heat or in the microwave, stirring halfway so it warms evenly.
If it looks a little dry, add a splash of water or a drizzle of olive oil to bring it back to life. For freezing, keep the squash and sauce separate; freeze up to 2 months and thaw overnight in the fridge before reheating.
Benefits of This Recipe
- Light yet filling: You get volume and texture without a heavy feeling.
- Weeknight-friendly: Minimal ingredients, hands-off roasting, and easy cleanup.
- Flexible for diets: Naturally gluten-free; easy to keep vegan or make dairy-free.
- Budget-smart: Squash and marinara are inexpensive staples.
- Veggie booster: A simple way to add more vegetables to your routine.
What Not to Do
- Don’t undercook the squash. If it’s still crunchy or wet, keep roasting. Properly cooked squash should form tender strands.
- Don’t skip seasoning. Salt and pepper bring out the squash’s natural sweetness and balance the sauce.
- Don’t drown it in sauce. You want the strands coated, not soupy.
Start with less; add more if needed.
- Don’t rush the sauce. Even jarred marinara benefits from a short simmer to wake up the flavors.
- Don’t forget texture. A sprinkle of cheese, herbs, or toasted nuts adds contrast and keeps every bite interesting.
Variations You Can Try
- Garlic and herb boost: Stir in extra sautéed garlic, a knob of butter, and chopped basil for richness.
- Veggie marinara: Add sautéed mushrooms, spinach, zucchini, or bell peppers to the sauce for more body.
- Protein add-ins: Brown Italian sausage, turkey, or plant-based crumbles and simmer in the marinara.
- Cheesy bake: Toss strands with sauce, transfer to a baking dish, top with mozzarella and Parmesan, and broil until bubbly.
- Puttanesca twist: Add olives, capers, garlic, and a touch of anchovy (or anchovy-free for vegan) for briny depth.
- Arrabbiata style: Use a spicy marinara with extra red pepper flakes for heat lovers.
- Lemon and herb finish: A squeeze of lemon and fresh parsley brightens the dish without more salt.
FAQ
How do I cut a spaghetti squash safely?
Stabilize the squash on a towel to keep it from rolling. Use a sharp chef’s knife to cut off the stem end, then slice lengthwise through the center. If it’s too tough, microwave the whole squash for 3–4 minutes to soften the skin slightly before cutting.
Is it better to roast the squash cut-side up or down?
Roasting cut-side down helps steam and caramelize the edges, giving you tender strands with a bit of flavor.
If you want drier strands, flip to cut-side up for the last 10 minutes so moisture evaporates.
Can I cook spaghetti squash in the microwave?
Yes. Place the halved, seeded squash cut-side down in a microwave-safe dish with a splash of water. Microwave on high for 10–15 minutes, checking every few minutes, until tender.
The texture won’t caramelize like the oven, but it’s fast.
What’s a good store-bought marinara?
Look for a short ingredient list: tomatoes, olive oil, garlic, onions, and herbs. Brands that use extra-virgin olive oil and no added sugar tend to taste fresher. Taste and adjust with a pinch of salt, a splash of olive oil, or red pepper flakes.
How do I keep the squash from getting watery?
Roast until fully tender, then let it sit cut-side down for a few minutes to release steam.
After shredding, you can let the strands rest in a colander for a minute or two. Avoid over-saucing; add just enough to coat.
Can I make this ahead for meal prep?
Absolutely. Roast the squash, shred it, and store separately from the sauce.
Combine portions as needed and reheat. This keeps the texture firmer and prevents sogginess.
What cheeses work well besides Parmesan?
Pecorino Romano adds a salty kick, while fresh mozzarella gives you gooey pulls if you bake it. Ricotta dollops make it creamy, and a sprinkle of feta or goat cheese adds tang.
How many servings does one squash make?
A medium spaghetti squash typically serves 2–4, depending on appetite and how many extras you add.
With protein or a side salad, it comfortably feeds four.
Can I keep it vegan?
Yes. Use a vegan marinara and skip the cheese, or finish with nutritional yeast for a savory, cheesy note. A drizzle of good olive oil also adds a nice finish.
What can I serve with it?
A crisp green salad, roasted broccoli, garlic bread, or a simple pan-seared chicken cutlet pairs nicely.
If you want extra comfort, add a small side of beans or lentils for protein.
