How To Make Roasted Butternut Squash
Cut the stem off the end of the squash. Split the butternut squash in half lengthwise. Scoop out the seeds using a spoon.
Lay the butternut squash skin side down on a baking dish. Stab the flesh of the squash with deep cuts using a fork or knife every 1" to 2".
Drizzle olive oil and sprinkle a little salt on top.
Roast butternut squash halves at 400℉ (205℃) for about an hour. The size of the squash affects roasting time. Remove the squash from the oven when the squash is fork-tender.
Roasting Tips
Different sizes of squash have different roasting times. If you bought a small butternut squash (about 1 to 2 pounds), the cooking time is closer to 45 to 50 minutes. A medium-sized squash (about 3 pounds) cooks for around an hour. For large butternut squash (about 4 to 5 pounds), the cooking time is closer to 70 minutes.
Ovens roast differently! Altitude and oven temperatures vary, so keep an eye on the squash while you roast.

Notes
- The size of the butternut squash affects the cooking time. For a small squash (1 to 2 lbs), check the squash at 45 minutes. A medium size squash (about 3 lbs) takes about an hour. For a large squash (4 to 5 lbs), you may need to cook for 70 minutes. The squash is finished roasting when it is fork tender.
- Store the squash in an airtight container in the fridge for up to 5 days and in the freezer for up to 6 months.
- Variations:
- Use butter or coconut oil instead of olive oil.
- Sprinkle some brown sugar on top of the squash before roasting. Drizzle some maple syrup or honey once the butternut squash is pulled out of the oven.
- Make roasted butternut squash cubes. Use a vegetable peeler and peel the outside of the squash. Cut the whole squash into 1-inch cubes. Spread the cubes on a parchment paper lined baking sheet in a single layer. Drizzle with olive oil. Sprinkle some salt and black pepper. Roast the squash at 400℉ (205℃) for about 25 to 30 minutes. The squash cubes take extra time to cut, but they take less time to roast.

Jane says
I made it with coconut sugar and a combination of oil and butter. Then I tossed it through some salad leaves. It's an easy way to enjoy butternut. I am wondering if I were to freeze it next time, what is the best way to reheat it?
Lily says
Hey Jane, if reheating butternut squash, just thaw it in the fridge the night before and use a microwave or oven.

I made this with brown sugar and butter. Will do it again, it was so simple.
