Butternut Squash in the Oven: Cubes or Halves

For butternut squash in the oven, roast 1-inch cubes at 425°F for 25–35 minutes, using 2 tablespoons of oil for one medium squash. Cubes develop the most browned, caramelized edges. For soft flesh that is easy to scoop or mash, bake halved squash for 45–60 minutes instead.

Use a large rimmed baking sheet and keep the squash in a single layer. The oven should be fully preheated before the squash goes in.

How to Roast Butternut Squash in the Oven

Heat the oven to 425°F. Prepare one medium butternut squash, about 2 to 3 pounds, with 2 tablespoons of olive oil, ¾ teaspoon kosher salt, and several grinds of black pepper.

Choose cubes when you want browned pieces for a side dish, salad, grain bowl, or pasta. Choose halves when you want tender flesh for scooping, mashing, or puréeing. A metal sheet pan encourages better browning than a small, crowded baking dish.

Peel, Seed, and Cut the Squash

1. Rinse and dry the squash. Slice off the stem and bottom ends.
2. Stand the squash upright, then carefully cut it in half where the narrow neck meets the rounded base.
3. Peel the neck and bulb with a sturdy vegetable peeler. Remove any remaining green or pale outer skin.
4. Cut the bulb in half lengthwise and scrape out the seeds and stringy fibers with a spoon.

For cubes, cut the peeled squash into 1-inch slabs, then cut each slab into 1-inch cubes. Keep the pieces close in size so they finish together. For halves, leave the two cleaned pieces intact. Smaller squash halves cook faster, while thick, large halves may need the full 60 minutes.

Roasting Squash in the Oven: 1-Inch Cubes

1. Place the cubes in a bowl. Add 2 tablespoons of oil, the salt, and pepper, then toss until every piece is lightly coated.
2. Spread the cubes across a large rimmed sheet pan. Leave a little space between pieces; overlapping squash will steam instead of brown.
3. Roast for 25–35 minutes, turning the cubes with a spatula after about 15 minutes.

The cubes are ready when a fork slides into the center easily and the edges are deeply golden with caramelized spots. Start checking at 25 minutes. Continue roasting for another 5–10 minutes if the centers remain firm or the edges look pale.

If the squash releases liquid and stays soft without browning, the pan is probably crowded. Transfer some pieces to a second pan and return both pans to the oven. Avoid adding extra oil, which can make the finished cubes greasy rather than crisp-edged.

Bake a Butternut Squash in Halves

1. Brush the cut sides of the squash halves with 1–2 tablespoons of oil. Season with salt and pepper.
2. Set the halves cut-side down on a rimmed baking sheet. Roast for 35–45 minutes.
3. Turn the halves cut-side up and roast for another 10–15 minutes, until the flesh is deeply tender and the cut surface has browned.

The total cooking time is usually 45–60 minutes. Test the thickest part with a fork or thin knife. It should slide in without resistance, and the flesh should pull away easily from the skin. If the center still feels firm, continue baking in 5–10-minute increments.

Let the halves cool for a few minutes, then scoop out the flesh. Discard the skin, or scrape it clean and reserve it for vegetable stock if desired. Halves generally produce softer, less browned flesh than cubes, but they require less cutting and are ideal for smooth purées.

Use and Store Roasted Squash

Serve roasted cubes immediately as a side dish, or add them to salads, tacos, grain bowls, pasta, and soups. Scoop baked halves into a bowl and mash them with butter, olive oil, or a little broth. They can also be blended into soup or used in fillings.

Cool leftovers promptly and store them in an airtight container in the refrigerator for up to 4 days. Reheat cubes on a sheet pan at 400°F for 10–15 minutes to restore some edge browning. Freeze mashed or cubed squash in airtight portions for up to 3 months, then thaw it in the refrigerator before reheating.
