Simple roasted spaghetti squash is the low-carb answer to pasta night — a hot oven turns the squash into tender, golden strands you scrape out with a fork. A little avocado oil, sea salt, and pepper is all it really needs. Serve it under your favorite sauce or eat it straight off the sheet pan.
Say hello to your new favorite side dish and the ultimate healthy pasta swap! Spaghetti squash is a culinary chameleon, transforming from a humble gourd into tender, noodle-like strands with just a little oven magic. Whether you’re piling it high with a hearty marinara, tossing it in a creamy Alfredo, or using the roasted halves as edible bowls for a delicious filling, the possibilities are truly endless. This simple, hands-off method guarantees perfectly cooked squash every single time.
Ingredients
• 1 large spaghetti squash, about 4 lbs / 1.8 kg (3.97 lb)
• 2 tbsp / 30 ml avocado oil
• Sea salt and fresh ground black pepper, to taste
Instructions
1. Preheat the oven to 400°F / 200°C. Line a large sheet pan with parchment paper.
2. Carefully use a knife to pierce holes all over the squash. Microwave on high for 7 minutes to soften the tough rind. Using oven mitts, remove the hot squash.
3. Slice the squash in half lengthwise and use a spoon to scoop out the seeds and pulp.
4. Drizzle the squash flesh with oil and sprinkle evenly with salt and pepper. Place the halves cut-side down on the prepared sheet pan and roast for 45 minutes, until the skin is tender.
5. Allow the squash to cool for a few minutes, then use a fork to scrape the inside, pulling the flesh into long strands. Serve immediately or store leftovers in an airtight container in the refrigerator for up to 5 days.

Pro Tips
• For longer, more defined ‘noodles’, slice the squash crosswise into rings instead of lengthwise before roasting.
• Don’t overcook your squash! It should be fork-tender, not mushy. Overbaking will result in watery, limp strands.
• Boost the flavor by adding a sprinkle of garlic powder, onion powder, or Italian seasoning along with the salt and pepper before roasting.
• Pick a winner at the store: Look for a squash that is firm, has a dry stem, is free of soft spots or cracks, and feels heavy for its size.
FAQ
Q: How do you make spaghetti squash easier to cut
A: To make the tough rind of a spaghetti squash easier to cut, first pierce it all over with a knife. Then, microwave it on high for 7 minutes to soften the skin, which makes slicing it much safer and easier.
Q: What is the best way to get long spaghetti squash noodles
A: For longer, more defined noodles, slice the squash crosswise into rings instead of cutting it in half lengthwise. The strands grow in a circular pattern, so cutting it this way keeps them intact.

Pro Tips
- Pierce the whole squash all over with a knife and microwave it on high for 7 minutes first — this softens the tough rind so you can slice it safely in half lengthwise.
- For longer, more defined 'noodles', slice the squash crosswise into rings before roasting instead of cutting it lengthwise.
- Roast the halves cut-side down at 400°F / 200°C for about 45 minutes, only until fork-tender — overbaking is what turns the strands watery and limp.
- Add garlic powder, onion powder, or Italian seasoning along with the salt and pepper before roasting for a flavor boost.
- At the store, pick a squash that feels heavy for its size with a dry stem and no soft spots or cracks. Leftovers keep in an airtight container in the fridge for up to 5 days.
