What is Butternut Squash?

Butternut squash is a pear-shaped Winter variety of squash and it comes out in the Autumn time. It grows on a vine and it has a nutty, sweet taste which is similar to a pumpkin. It is tan in color and has a flesh that is orange with seeds at the round end of the bell shape. 

We all think of butternut squash as a vegetable but botanically it is actually a fruit. However, culinarily it is used as a vegetable and is commonly roasted, sauteed, or pureed.

What Does Butternut Squash Taste Like?

Roasted butternut squash tastes sweet with a nutty flavor. Some people think that it tastes like carrots, turnips and sweet potatoes. It is popular as soon as Autumn comes because it makes great purees and soups.

A 1 cup serving of butternut squash has 63 calories.

Is Butternut Squash a Bad Carb?

Butternut squash is referred to as a starchy vegetable, just like potatoes, because it’s higher in carbs than other ones like broccoli and cauliflower. 

However, butternut squash is not a bad carb, like bread, pasta or cake. It’s a good carb just like some other veggies are. Since it is so nutritious, it helps to outway the carb count.

Is Roasting Butternut Squash the Healthiest Way to Eat It?

In my opinion, baked butternut squash is one of the healthiest ways to eat it as it retains most of the nutrients, unlike other preparation methods.

When we roast butternut squash we roast it in a very simple way with just a touch of olive oil brushed on with a little salt and pepper sprinkled on top. You can eat it just like that right out of the oven or use it in a bunch of great recipes for a healthy side dish or one dish meal.

How Many Ways Can You Cook Butternut Squash?

Roasted Butternut Squash cubes

There are six ways to cook butternut squash and we are going to show you each one in detail.

Roasted in the Oven in Halves – To roast butternut squash just cut the squash in half lengthwise and scoop out the seeds, season the top with a little olive oil and some spices.

Roasted in the Oven in Cubes – For baked butternut squash I like to peel the squash first, cut it in half, and then into cubes. see our site for recipe how to cut it

Roasted Whole (No Cutting) – If you are afraid to use a knife to cut the squash in half, cooking it whole is certainly an option. You can just put it on a baking sheet and roast it at 425 for 45 minutes. After the timer goes off, check to see if it’s cooked or still hard and put it back in the oven, checking it every 10 minutes.

Microwave – Cooking butternut squash in the microwave is easy. Peel it, take the seeds out and cut it into cubes. Cover it and microwave it for 4 minutes. Stir it up and cook for another 2 minutes. But all microwaves are different so test it out with a fork.

Instant Pot – Whats nice about cooking butternut squash in the instant pot is that you can just place it right in on top of the trivet, add 1 cup of water and cook on high for about 20-25 minutes. You can either mash it or make it into cubes.

Slow Cooker – Using a slow cooker when cooking butternut squash is another method to use. You don’t have to peel it or take the seeds out. Just wash it off and toss it into the crock pot. Cover and cook for 4-5 hours on high or 6-8 hours on low. Poke it with a fork to see if it’s done.

What Ingredients Do You Need to Roast Butternut Squash?

Seasoning Butternut Squash
  • Butternut squash – This is, obviously, the key ingredient in baked butternut squash and is loaded with so many nutrients that make this a good choice in your diet.
  • Olive Oil – This gets brushed on the squash after you cut it in half or in cubes for roasting. A little oil goes a long way.
  • Salt – A basic spice that enhances the flavor of the squash.
  • Pepper – a little bit of black pepper added to the salt will give just enough kick to the baked butternut squash.

Can I Use Pre-Cut Butternut Squash?

If you are trying to save some time by buying the butternut squash already cut into cubes, feel free to do so, it’s the easiest way. We used to do that until we learned how to cut it in half, peel it, and cut it into cubes ourselves.

Just be aware that like anything else, when the store puts the work into it it only makes sense that they are going to charge you a lot more money than if you bought the butternut squash whole and cut it yourself. 

Stephanie used to buy the squash precut to make her roasted butternut squash recipe and it used to cost her about $20-25 dollars for the cubed squash. Instead now she buys the same amount of whole butternut squash for about $7-8 dollars.

When you buy pre-cut squash to make baked butternut squash it doesn’t last too many days in your refrigerator so you need to use it up pretty quickly. If you buy the squash whole it can last for a few weeks in your refrigerator so we tend to buy it when it’s on sale and keep it on hand. Or if you have a local farm that carries fresh vegetables, we recommend buying it from there.

Roasted Butternut Squash Variations

There are so many different things that you can put on your roasted butternut squash for variation in flavor.

  • Maple syrup or brown sugar for a sweet taste, and if you are watching your carbs there are low carb versions of both of these. Swerve makes a brown sugar replacement sweetener and there is also a  maple syrup made by lakanto that is low carb too.
  • You could also season the squash with warm autumn spices such as cinnamon and nutmeg.
  • Garlic and onion powder are always good flavors for vegetables.
  • You could always dress up the roasted butternut squash with similar toppings to a baked potato such as butter, sour cream, bacon bits, chives, cheddar cheese….etc
  • Chopped parsley or rosemary will dress up the look of the squash and are both quite delicious.

What Can You Make with Butternut Squash?

Butternut squash is a very versatile vegetable and can be used in a lot of different foods. Once you learn how to cook butternut squash, try it in these recipes:

Picking Out a Good Butternut Squash

Butternut Squash on cutting board

It’s easy to pick out a good butternut squash. Just make sure that the squash is firm in texture and it’s best when there are no soft spots, bruises or scrapes on it. 

Make sure that the color is all beige, not partially green or brown. Also a more matte finish instead of a shiny skin which is a sign that it will soon start to go bad. 

I also like to get one with a good stem on it because the longer the stem the better the squash. If the squash is heavy that’s good. If it’s too light it means it’s so full of seeds and not enough meat. 

If you get a good one it can last for a couple of months in your refrigerator until you get around to cooking butternut squash.

When is Butternut Squash in Season?

Butternut squash is considered a winter squash, but it is available in our stores for about ¾ of the year, and commonly found in the fall, winter, and spring. I don’t see it in the summer because the store’s focus is more on summer squash, like zucchini…etc.

How to Tell When It’s Ripe?

It’s pretty easy to tell if your squash is ripe and ready to use to make roasted butternut squash, just look at the color and texture of the outer skin. 

If there are any green spots on the outside then the squash is not ripe yet for sure. The skin should be hard but not glossy and an even creamy tan color. When it’s glossy it means that it is soon going to spoil. 

If it is young and not ripe it is still edible, but the flavor will be dull and not as sweet and tasty as it is when the squash is ripe. Think of a peach for instance. When it’s not ripe it is hard and almost tasteless. But let that same peach ripen up and the flavor is more pronounced, sweet and juicy.

Tools to Use

It doesn’t take a lot of tools in order to make this roasted butternut squash recipe, which is always a nice thing when making something is a simple process.  

In this article we will show you how to roast butternut squash and what tools that you will need to do so:

  • Large cutting board
  • Large sharp knife
  • Vegetable peeler
  • Baking sheet
  • Brush

NOTE: PLEASE BE CAREFUL WHEN USING A SHARP KNIFE. I like to put an anchor underneath the cutting board to hold it in its place so it doesn’t slide while you are trying to cut on it. For instance, use a towel or flat pot holder to keep the board still.

How to Peel and Cut a Butternut Squash

Cutting Butternut Squash

When you need to peel your butternut squash, it’s not hard at all if you have the right tools. To cook butternut squash there are two ways to cut it, one is in half lengthwise and the other is in cubes. We will show you both ways.

Do You Have to Peel a Butternut Squash Before Roasting It?

When you are cooking butternut squash you can roast it either with the outer skin or without it. In this recipe we roasted it both ways. It’s really a preference.

We roasted it with the skin on just cut in half, and then we peeled one and cut it into cubes before roasting it.


Let’s show you how to roast butternut squash, with the skin on and with the skin off.

Cutting Butternut Squash In Half:

  1. Anchor your cutting board with a towel underneath so that the board will not move when you are trying to cut your squash in half.
  2. Carefully using your sharp knife, cut the squash in half lengthwise leaving the stem on one side.
  3. Now lay it on a cookie sheet flesh side up, remove the seeds and get ready to season it.

Cutting Butternut Squash In Cubes:

  1. First, cut both ends of the squash off.
  2. After cutting off both ends take the squash in one hand and the peeler in the other and peel it downwards all the way around the squash until all of the skin is peeled off.
  3. Then cut it in half lengthwise and then begin to cut it into cubes. 

TIP: For best results roasting, cut butternut squash into 1” cubes.

For more detailed instructions, read our Guide to Peeling and Cutting Butternut Squash.

Can You Eat the Skin of a Butternut Squash?

You may wonder if you can eat the skin of the butternut squash or if you should discard it? The skin is edible if you really want to eat it, but you may find it a bit too hard and tough to eat it, especially if your butternut squash is larger in size. 

If you have a young, tender squash then you may find eating it more pleasurable.

What to Do with the Seeds?

Butternut squash seeds can also be roasted and can be eaten as a tasty, low calorie and ow carb snack. If you have ever taken the seeds out of a pumpkin then you know what to do with the seeds in a butternut squash.

Roasting Butternut Squash Whole (Without Cutting It)

Which Way is Best to Roast Butternut Squash?

Roasted Butternut Squash in a bowl and on a tray

It’s very hard to pick a favorite way to roast butternut squash, and there are a few factors that will help you decide.

I think the easiest way is to roast it whole because you don’t have to worry about using a knife. The only downside to this way is that it takes longer to cook. 

Cutting butternut squash in half is also easy. Just season it, pop it in the oven, set the timer and take it out when it’s done.

My favorite way to make roasted butternut squash in cubes. It’s my favorite because it takes the least amount of time to cook and since there are exposed pieces on the tray they caramelize better.

Best Tips

It’s always good to have helpful hints if you have never made a dish before, so here are a few things that will help you make this roasted butternut squash recipe.

  • If you throw your squash in the microwave for a minute it will help to loosen up the skin and make it easier to peel.
  • If you have a dark cookie sheet then use it to make roasted butternut squash because the dark color will encourage the squash to brown easier. 
  • You can broil your roasted butternut squash the last couple minutes if it needs to brown up more.
  • If you want the squash to brown up better ditch the parchment paper.
  • If you want your roasted butternut squash to be spicy then toss some crushed red pepper in while roasting it.
  • Do not overcrowd your baking sheet for better caramelizing results.
  • Make sure when picking out your squash, to get one without cuts and scrapes and one with a matte, tan finish. If it’s heavy it means a good amount of flesh. If it’s light then it’s full of seeds and not as much flesh.
  • When using a cutting board it is always best to anchor it on the counter to avoid it slipping while cutting on it. You can use a dish towel or flat pot holder under it to keep it still. 
  • If you want to save oven space then use an instant pot.
  • If you are short on time then use the microwave.
  • If you want it to cook while you are at work or sleeping then use a slow cooker.

My Squash is Too Mushy

Butternut squash can be mushy if you used a squash that was over ripe to start with. The mushy texture can also come from overcooking the squash too.

So follow the guidelines that we set out above in this recipe for buying the squash and cooking the squash to have the best results.

Why is My Butternut Squash Bitter?

Roasted butternut squash should have a sweet taste, so if your roasted butternut squash has a bitter taste it is probably due to what happened to it during the growing process, because of irrigation or temperature. It takes away from how the squash should really taste so throw it out and start over.
