Roasted Spaghetti Squash Recipe: Crispy, Easy & Ready in 45 Minutes

Roasted spaghetti squash can end up watery or undercooked, which is frustrating. This recipe uses an easy roasting method for fluffy, noodle-like strands and caramelized edges.

No more mushy squash—this might become your favorite low-carb side.
What Is Roasted Spaghetti Squash?
Roasted spaghetti squash is a winter vegetable baked until tender, then scraped into long, spaghetti-like strands. Cut it in half, brush with oil, and roast cut-side down so it steams in its own juices for the best texture. This method gives about 4 cups of strands from a medium squash, making it a great gluten-free pasta alternative. Its natural sweetness and mild flavor go well with any sauce or topping.

Ingredients
Serves 4 as a side (two halves per person). Prep time: 10 minutes. Cook time: 45 minutes.
For the squash:
- 1 medium spaghetti squash (about 3–4 pounds)
- 2 tablespoons olive oil
- 1 teaspoon kosher salt
- ½ teaspoon black pepper
Optional toppings (pick 2–3):
- 2 tablespoons grated Parmesan cheese
- 1 tablespoon fresh parsley, chopped
- Red pepper flakes to taste
Substitutions
- Olive oil: Avocado oil or melted butter for a richer flavor.
- Salt: Sea salt or garlic salt for extra punch.
- Squash size: Use two small ones if medium ones are unavailable—adjust time by 5 minutes.
Step-by-Step Cooking Instructions
- Preheat oven: Set to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
- Prep the squash: Rinse under cool water and pat dry. Use a sharp knife to cut off the stem end. Slice in half lengthwise. If it’s tough, gently rock the knife back and forth. Scoop out the seeds and stringy bits with a spoon. The inside should look bright orange.
- Season: Brush cut sides and cavities with olive oil. Sprinkle salt and pepper evenly. The oil helps crisp the edges.
- Position for roasting: Place halves cut-side down on the baking sheet. This traps steam for tender strands.
- Roast: Bake for 40–45 minutes. Check at 40: edges are lightly browned, and squash yields to a fork press. A sweet, nutty aroma fills your kitchen.
- Cool and scrape: Let the squash cool for 5 minutes to avoid burning your hands. Hold with a towel and use a fork to rake along the flesh in one direction. The strands will come out golden and fluffy.
- Serve: Twirl onto plates. Add toppings while warm for melting cheese and bright herbs.
Total time: 55 minutes.

Expert Cooking Tips
I’ve roasted hundreds of these over 30 years, and here’s what works. Pick squash that feels heavy for its size, since that means more flesh. For extra crispiness, roast cut-side up for the last 5 minutes. To check if it’s done, pierce the rind; it should feel soft like a baked potato. Store leftovers in an airtight container for up to 4 days, and reheat them in a skillet with oil to restore texture. You can also freeze the strands flat in bags for up to 3 months and thaw them overnight.
If your oven runs hot, drop it to 375°F. For meal prep, roast multiples; they reheat like pasta.
Common Mistakes to Avoid
- Skipping the oil: Dry squash can turn chewy because oil helps evenly distribute heat.
- Roasting cut-side up: Strands get watery; in the down position, they steam perfectly.
- Overcooking: Beyond 50 minutes, it mushes—set a timer.
- Forking too soon: Scalding steam burns; cool 5 minutes first.
- Thin squash: Small ones cook faster—check at 35 minutes.
Real Cooking Scenario
Last Tuesday, after a long day, I grabbed a spaghetti squash from the fridge. Kids wanted pasta, but we needed lighter. Halved it while dinner chatter filled the kitchen, popped it in the oven, and scrolled emails. Forty-five minutes later, golden strands hit plates with butter and herbs. Everyone raved—my picky eater went back for seconds. Clean up? Just toss the parchment. Weeknight win.
