If you’ve ever ended up with a watery puddle of vegetable noodles on your plate, you’re not alone. Spaghetti squash is 92% water, which means traditional boiling or careless roasting turns it into soggy soup. In this definitive masterclass on how to cook spaghetti squash, we reveal two restaurant-tested hacks—cutting crosswise and salt-sweating—that guarantee extra-long, toothsome, al dente strands that grip tomato or Alfredo sauce like real pasta.

How to Cook Spaghetti Squash (Al Dente Strands, Never Watery)
Ingredients
Method
- Cut crosswise (The secret to long strands): Cut the stem and bottom end off the squash. Instead of cutting lengthwise, slice the squash crosswise into 1.5-inch thick rings, or halve crosswise. The squash fibers run in circles around the squash, so cutting crosswise keeps the noodles extra long!
- Scoop seeds & salt-sweat (Prevents wateriness): Scoop out the inner seeds and stringy pulp with an ice cream scoop. Sprinkle the cut flesh with 1 tsp coarse salt and let stand on paper towels for 15 minutes. Wipe away the beads of moisture that sweat out.
- Season and roast cut-side down: Preheat oven to 400°F (200°C). Brush the squash flesh lightly with olive oil and season with black pepper and garlic powder. Place cut-side DOWN onto a parchment-lined baking sheet.
- Roast for 35 to 40 minutes: Roast undisturbed until the skin blisters slightly and a knife tip easily pierces the outer skin. Do not overcook into mush.
- Fluff into spaghetti noodles: Let cool for 5 minutes until safe to handle. Take a dinner fork and gently pull from the outside edge inward to fluff out mounds of long, al dente spaghetti noodles. Toss with marinara, garlic butter, or our homemade Alfredo sauce!
The 2 Game-Changing Hacks for Better Spaghetti Squash
- Cut Crosswise into Rings (Not Lengthwise): Almost every recipe tells you to split the squash lengthwise from stem to tip. But the natural strands of spaghetti squash run in concentric circles around the diameter. Cutting lengthwise chops every strand in half! Cutting crosswise into rounds preserves the unbroken 10-inch noodle strands.
- The 15-Minute Salt-Sweat: Sprinkling the cut flesh with coarse salt before roasting acts like an osmotic pump, pulling out excess water that would otherwise steam the squash into mush. Dab it dry with paper towels, and your squash will roast sweet, nutty, and dry.
Frequently Asked Questions about Cooking Spaghetti Squash
Can I cook spaghetti squash in the microwave if I am short on time?
Yes! Halve crosswise, scoop out seeds, place cut-side down in a microwave-safe baking dish with 2 tablespoons of water, and microwave on HIGH for 10 to 12 minutes until tender. While it won’t have caramelized roasted edges, it is ultra-fast.
How do I make cutting a raw spaghetti squash easier and safer?
Raw squash skin can be rock-hard. Poke 8 to 10 holes along your intended cut line with a paring knife, then microwave the whole squash for 3 to 4 minutes. This softens the outer skin just enough for your chef’s knife to glide through safely.
What sauces pair best with spaghetti squash?
Rich sauces that cling work best: our Easy Homemade Alfredo Sauce, a robust meat Bolognese, garlic herb brown butter with sage, or classic marinara with melted mozzarella.
How many carbs are in spaghetti squash compared to regular pasta?
One cup of cooked traditional wheat pasta has roughly 43g of carbohydrates and 220 calories. One cup of cooked spaghetti squash contains only 10g of carbohydrates (8g net carbs) and 42 calories, making it a keto and diabetic-friendly superfood.
