How to Pick the Best Butternut Squash
Before you learn how to roast whole butternut squash, it’s important to know a few things like what does butternut squash look like and how to pick a ripe one. Here is what to look for at the grocery store:
- Heavy: No lightweights here! Just like acorn squash and spaghetti squash, your squash needs to be solid and heavy. Don’t be afraid to pick a few up and compare them.
- Color: A light tan or beige color with no visible green or dark spots.
- Skin: Surface imperfections are normal, but if there are soft spots, deep scratches, or large cuts, skip it!
- Stem: If the stem is still there, it should be dark brown.
Do I Need to Peel and Chop It?
That’s the best thing about roasted whole butternut squash, you don’t have to do either!
So if the idea of peeling, then making butternut squash cubes sounds daunting, this is not only a timesaver but the best way to cook butternut squash.
That being said, though, if you want a more caramelized flavor, you will need to roast halved butternut squash or roast butternut squash cubes. Lucky for you, I include those directions below, too!
How to Roast Butternut Squash Whole
Whether you are new to cooking with butternut squash or a seasoned cook, to bake butternut squash whole really is the easiest way. Recently I started cooking spaghetti squash whole and that’s when I thought you can cook any squash whole!
The flesh is buttery, the skin easily pulls offs without using a vegetable peeler, and the seeds scoop right out. This is the best method if you want to make squash soup.
- Place whole squash on baking tray lined with parchment paper or aluminum foil and poke 5-6 times with a sharp knife.
- Roast at 425 degrees F for 60-80 minutes. Time will be dependent on the size of your squash. It is done cooking in the oven when a knife easily pierces the skin.
- Remove squash from oven and let it cool for about 20 minutes or until it is safe to handle. Transfer to a cutting board and carefully slice in half lengthwise.
- Use a large spoon to scoop out the seeds and stringy parts. Discard or roast them just like pumpkin seeds in the air fryer. Remove the peel and use remaining squash flesh as desired.
Squash will also appear mottled brown and a bit shriveled on the outside when it is done roasting in the oven.
How to Bake Butternut Squash Halves
Roasted butternut squash halves is another easy method of how to prepare butternut squash whole. While you will need to cut it your squash in half, there is no need to peel the skin.
- Prep: Cut raw butternut squash in half lengthwise, then remove seeds and stringy parts.
- Place on large baking sheet: Place on a sheet pan cut side up. Brush a light coating of olive oil on entire surface of the squash and sprinkle with salt and pepper.
- Bake: Roast in the oven for 50 minutes until it is fork tender and golden brown. A knife should easily pierce the outer skin.
- Cool: Cool slightly for 5 – 10 minutes then scoop out the soft flesh to use in recipes or stuff with your favorite grain.
How to Cut Butternut Squash in Half
- Trim stem: Hold the squash firmly in the middle with one hand. With a sharp knife held in your dominant hand, trim the top by cutting a 1/2 inch off. If you would like to trim the bottom part, use the same method. It’s not necessary to do so, though and a matter of personal preference.
- Cut in half: Holding it firmly on its side, cut it lengthwise from top to bottom. To make it easier, make deep cuts with tip of a sharp knife on one side, turn squash over and repeat the same on the other side. Apply some pressure as you are cutting to loosen it. Do not rush.
- Remove seeds: Scoop out seeds and stringy parts with spoon or ice cream scoop. Your halves are now ready to roast.

Make Ahead and Storage Tips
Save some time on Thanksgiving Day and make your butternut squash ahead of time and then just reheat it for a great side dish! How you store your winter squash depends on if you will be scooping out the flesh or serving it as halves.
Store: For scooped out squash from roasting it whole, store in an airtight container up to 3 days. For roasted halves, let cool to room temperature then wrap each half tightly with plastic wrap and store in the refrigerator until ready to warm up and eat.
Reheat: Reheat your whole butternut squash in an oven safe dish or microwave until warmed through. To reheat your butternut squash halves, unwrap and place in a baking dish. Warm up in the oven at 350 degrees F 10-15 minutes until warmed through.
Technically yes, but most people don’t eat the skin of the squash. Most recipes will also call for you to peel the skin off your squash.
Uncooked butternut squash can be stored in a cool dry place for 1-3 months.
Cooked butternut squash can be stored in the fridge in an airtight container up to 3 days.
Other than being so sweet and delicious, butternut squash is good for you! It’s high in fiber, yet low in calories plus contains vitamins A, C, and E. It is also a great source of potassium.
