What is butternut squash?
Butternut squash, also known as gramma or butternut pumpkin, is actually a fruit — although many think it is a vegetable. This winter squash grows on a vine and has a sweet and nutty taste, similar to a pumpkin.
It has a long shape and orange starchy pulp with a tan-yellow skin. You can cut and peel and then cook butternut squash in many different ways: boiled, roasted, sautéed, steamed, roasted, stewed, and even grilled. It can be cut into different shapes and sizes too!
If you are on a gluten-free diet, you may enjoy cooking butternut squash noodles. You can even purée it and make a butternut squash mac and cheese. The cooked squash is mixed into the cheese sauce and tossed with the cooked macaroni.
As you can see, it is a versatile ingredient that goes well in both savory and sweet dishes.

Is it healthy?
Yes! Butternut squash is a good source of fiber, vitamin A and C, magnesium, and potassium. It has about 16 g of carbs per cup and so is not really keto-friendly. If you are on a keto diet, you may consume it, but in low amounts.
How to Buy Butternut Squash
Choose a butternut squash that has a tan or beige color and no deep cuts or bruises. It should feel heavy for its size!
How to peel and cut Butternut squash
Is peeling butternut squash necessary? Well, it depends on how you plan to cut and cook it. If you want to scoop out the flesh or pulp to make a mashed squash for example, you can cook it whole in the microwave after making some slits (about ¼-inch deep) in the flesh to vent. Then, cut in half, remove the seeds, and scoop out the flesh. In this case, it is not necessary, but if you wish to cut it into cubes to roast and serve as a side dish, peeling is needed.
Preparing butternut squash may seem intimidating.
But I will show you how simple it is to peel and cut butternut squash, as follows:
- Wash squash thoroughly using a vegetable brush. This will help to avoid contaminating the vegetable peeler! Then, pat dry to keep the peeling process from getting slippery.
- Next, cut off the ends and slice the squash in half crosswise. SEE PICS. 1 & 2 This will allow you to place each half upright in a steady position on the cutting board. SEE PIC. 3
- Using a vegetable peeler or a sharp knife, peel off all the skin. SEE PIC. 4
- Cut halved squash into quarters. SEE PIC. 5 Then, remove both the seeds and attached strings using a spoon or ice cream scoop.
- At this point, you may cut the squash into slices or into ¾ to 1-inch cubes. Or you can cook the quarters in the Instant Pot, for example. SEE PIC. 6
How long to roast butternut squash?
As you will see below, it takes around 35-40 minutes at 400 degrees F (200 degrees C) in a preheated oven to roast squash. Time may vary depending on oven temperature variations, altitude, and the size of the squash cubes.

- Drain or remove cooked squash with a slotted spoon. You may serve with butter while still hot or with a hint of extra virgin olive oil.
In the crockpot:

- Place whole squash in a microwave-safe dish and cook for about 10-12 minutes (1200 Watt oven) or more depending on the potency of your microwave.
- Check if tender enough by pricking the cooked squash with a fork. Allow it to cool just enough to handle.
- Cut cooked butternut squash in half and remove seeds and strings with a spoon. Cut into slices or cubes, or scoop out the flesh.
Can You Eat the Skin?
Cooked butternut squash skin is edible and it contains a lot of nutrients such as fiber, vitamins, and minerals.
However, the skin may be tough to eat if the squash is old. In this case, discarding the skin is the best option! But if the squash is young, the skin is usually tender enough to eat.
What to serve with cooked squash
You can use the flesh or pulp of cooked butternut squash to make soups such as Autumn squash soup, mashed butternut squash, rolls, sweet bread, pies, cakes and muffins, and others.
When cubed and roasted, it goes well in salads or as a side for roast chicken, roast turkey, this honey baked ham, and our slow cooker ham.
Storage
If raw, uncut squash will keep well for 3-4 months if stored in a cool and dry place. Discard if it becomes soft, moldy, or squishy.
If cooked, store butternut squash in an airtight container in the fridge for 3-4 days, or a freezer bag in the freezer for up to 3-4 months. If freezing cooked and cubed squash, place the cubes on a parchment paper-lined baking sheet and freeze until solid before putting them in a bag/container. This simple step will prevent them from sticking to each other.
