Want to know the best way to cook spaghetti squash? Roasting yields tender, flavorful strands every time, but you can also prepare it quickly in the microwave or set it and forget it in a slow cooker. Below are clear, practical methods for all three approaches, plus tips for choosing, cutting, serving, and storing spaghetti squash.
The Best Ways to Cook Spaghetti Squash
Spaghetti squash is a versatile, low-calorie vegetable (technically a fruit) that works as a side, a low-carb pasta substitute, or the base for stuffed “boats.” Roasting concentrates its natural sweetness and gives a lightly caramelized edge, but the microwave and slow cooker are excellent alternatives when you need speed or convenience.
Why You’ll Love Spaghetti Squash
- Extremely versatile. Use it as a pasta alternative, a side dish, or a vessel for toppings and fillings.
- Three easy cooking methods. Roast, microwave, or use a slow cooker depending on time and preference.
- Healthy and filling. Low in calories, higher in fiber than many starchy sides.
- Gluten-free naturally. A great option for those avoiding gluten.
How to Pick a Good Spaghetti Squash
When selecting a ripe spaghetti squash at the market, check for:
- Firm, unblemished skin with no soft spots
- A consistent golden-yellow color
- No cracks or splits in the rind
- A dry, sturdy stem
How To Cut Spaghetti Squash
Cutting a raw spaghetti squash can be intimidating because the rind is thick. These tips make it easier and safer:
- Soften first (optional). Microwave the whole squash for 2–3 minutes to slightly soften the skin if you’re nervous about cutting it.
- Trim the ends. Slice off a small amount from the top and bottom to create flat surfaces and make the squash more stable on the board.
- Slice lengthwise. Cut from stem to base so the natural fibers will form long, spaghetti-like strands when scraped with a fork.
How to Cook Spaghetti Squash (3 Ways)
Use the method that fits your schedule. Roasting is my favorite for flavor and texture, but microwave and slow cooker methods work well too.
Oven (Roasted Spaghetti Squash)
Roasting brings out sweetness and gives a pleasant texture.
- Prepare. Preheat oven to 350°F. Cut the squash in half lengthwise and scoop out the seeds and stringy fibers. Season cut sides with salt and pepper.
- Roast. Place halves cut side up on a baking sheet. Roast about 1 hour, until the skin yields when pressed and the flesh is tender.
- Shred. Let cool about 10 minutes, then use a fork to scrape the flesh into long strands.
Microwave
Fast and practical when you need spaghetti squash in a hurry.
- Poke the skin. Prick the exterior 8–10 times to vent steam.
- Microwave. Microwave on high for 6 minutes, turn it over, then microwave another 6 minutes. Times vary by microwave and squash size.
- Finish and shred. Let the squash cool 8–10 minutes. Cut it open (or in half crosswise), remove seeds, and shred the flesh with a fork. If it’s still firm, microwave a few additional minutes.
Slow Cooker
Great for hands-off cooking and minimal prep.
- Prepare. Prick the outside 8–10 times to allow steam to escape. Place whole squash in the slow cooker with 1/2 cup water.
- Cook. Cover and cook on low for 4–6 hours, until the squash is tender.
- Cool and shred. Allow to cool 10–15 minutes, cut open, remove seeds, and shred with a fork.
How Do You Know When Spaghetti Squash Is Done?
Fully cooked spaghetti squash should be tender inside and give slightly when the rind is pressed. You should be able to pierce the skin easily with a fork, and cutting the squash should meet no resistance. If it’s still firm, continue to cook a bit longer.
Ways to Use Spaghetti Squash
Spaghetti squash adapts to many preparations. Some popular uses:
- Serve with marinara or tomato sauce for a quick, low-carb “pasta” dinner.
- Fill the halves to make “boats” topped with meats, beans, cheese, or vegetables.
- Make a lighter mac-and-cheese using roasted squash strands and a cheesy sauce.
- Toss with garlic, butter or olive oil, herbs, and grated cheese as a simple side.
- Serve under a ragu or meat sauce in place of traditional pasta.
Proper Storage
- Fridge. Cooked spaghetti squash keeps 4–5 days in an airtight container in the refrigerator.
- Freezer. Cool completely, pack into freezer bags or containers (remove excess air), and freeze. Thaw in the fridge before reheating.
- Reheat. Reheat gently in the microwave or on the stovetop until warmed through.
