How to Make Spaghetti Squash Marinara

Step 1: Prep and Roast the Squash

Preheat your oven to 400°F. Slice the spaghetti squash in half lengthwise and scoop out the seeds. Brush the inside with olive oil, sprinkle with salt and pepper, and place it cut-side down on a baking sheet. Roast for about 35–45 minutes, until the flesh is fork-tender and shreds easily into strands.

Step 2: Make the Sauce

While the squash roasts, heat olive oil in a skillet over medium heat. Sauté chopped onion until soft, about 5 minutes. Add garlic and cook for another minute until fragrant. Pour in the marinara sauce and let it simmer gently for 10–15 minutes to deepen the flavors. Stir in fresh herbs at the end.

Step 3: Combine and Serve

Once the squash is cool enough to handle, use a fork to scrape the flesh into spaghetti-like strands. Plate the squash, spoon the warm marinara over it, and top with grated parmesan and a sprinkle of fresh herbs if you like. Serve warm and enjoy!

Pro Tips for Making the Recipe

• Cutting Tip: If slicing the squash is tricky, microwave it whole for 3–4 minutes to soften the skin slightly.
• Flavor Boost: Add a splash of balsamic vinegar or a dash of Italian seasoning to your marinara for an extra punch.
• Cheese Matters: Freshly grated parmesan melts better and has way more flavor than pre-shredded.
• Don’t Overcook the Squash: You want tender strands, not mush. Check doneness around the 35-minute mark.

How to Serve

This Spaghetti Squash Marinara is super versatile when it comes to serving:

Main Course

Serve it just as it is for a satisfying, veggie-forward main dish. Add a side salad or garlic bread if you’re not keeping it low-carb.

Protein Pairing

Top with grilled chicken, sautéed shrimp, or even a fried egg to add protein and turn it into a full meal.

Fancy It Up

Drizzle with basil pesto or a dollop of ricotta for a gourmet twist.

Make Ahead and Storage

Storing Leftovers

Let leftovers cool completely before transferring to an airtight container. Store in the fridge for up to 4 days.

Freezing

Spaghetti squash doesn’t freeze super well on its own—it can get watery. But if you must, store the strands and sauce separately and reheat together later.

Reheating

Reheat in the microwave or in a skillet over medium heat. Add a splash of water to loosen the sauce if needed.

FAQs

Can I roast the squash ahead of time?
Absolutely! You can roast the squash a day or two in advance. Just store the strands in the fridge and reheat when ready to serve with the sauce.

Is spaghetti squash actually healthy?
Yes! It’s low in calories and carbs but high in fiber and vitamins, making it a fantastic alternative to traditional pasta.

What’s the best marinara sauce to use?
Go for a high-quality jarred sauce with simple ingredients—tomatoes, garlic, herbs. Or make your own if you’ve got an extra 20 minutes.

Can I make this dish vegan?
It already is! Just skip the cheese or use a vegan-friendly version, and you’re good to go.
