Oven Roasted Butternut Squash

Sitting on my kitchen counter right now are three whole butternut squash. Along with pumpkins, apples, pears etc.

The reason for three whole butternut squash is quite simple – I CANNOT GET ENOUGH OF IT. And since it is seasonal, I’ll make sure I eat my share of it while they are still around.

Such an underrated fruit, butternut squash (also known in Australia and New Zealand as butternut pumpkin or gamma, thank you Wikipedia) is a great source of Vitamin A, Vitamin C, and fiber. It’s actually part of the winter squash family too (think acorn, kabocha, and delicata squash) – it just happens to be harvested in early Fall.

Its flesh has a sweet nutty taste – kinda similar to pumpkin. Its texture is hard uncooked but once baked it is nice and tender.

There are so many ways to cook butternut squash – and whole roasting butternut squash is always my #1 way of preparing it.

But let’s face it, roasting is my favorite way to make ANY squash. Proof: Here I am roasting spaghetti squash! P/S: It’s SO good.

Most recipes involve peeling the butternut squash before roasting it, but I find that part a bit tedious. That’s why I want to share how I make whole roasted butternut squash – one of the simplest and basic way to cook a butter squash, yet the tastiest.

Once butternut squash is roasted, you can cut it into small cubes, puree it, add it to salads, make soups out of it (speaking of soups, this delicious Curry Butternut Squash Soup is a butternut squash lovers’ dream!) etc. The list goes on; the possibilities are endless!

Ingredients

Butternut squash: The whole star of this recipe – it roasts right in its own skin, so there’s no peeling or pre-cubing needed.
Olive oil: Helps the seasonings stick and is what gives the squash that caramelized, slightly crispy top. Extra virgin olive oil works great, or swap in any neutral oil like avocado or canola oil. Melted butter is a tasty substitute too (reduce the salt slightly if using salted butter).
Sea salt: Brings out the natural sweetness of the squash. Kosher salt or another favorite salt works just as well.
Black pepper: Adds a subtle bit of warmth and kick. Optional if you’d rather keep things purely sweet.
Brown sugar: Caramelizes as it bakes, deepening the natural sweetness and helping create that golden, slightly crispy top.

Baking Butternut Squash Whole

Today is the day you get to enjoy butternut squash close to its purest form – whole. No peel, no dice, just yum. 🧡

One that requires minimal ingredients and prep, and yet brings out all the flavor it has to offer.

I love buying a whole butternut squash instead of the pre cut ones because they are usually the freshest, and the most budget friendly. They also last a lot longer than the pre-cut ones if you don’t intend to cook it immediately.

How to cut butternut squash

Before we talk about how to roast butternut squash, let’s talk about how to cut a whole butternut squash.

I don’t know about you, but when I first made Whole Roasted Butternut Squash, this is the most intimidating part for me.

How do I break apart this giant of a fruit?

If you are also asking that question, let’s dive straight in!

Before any cutting happens, give the whole butternut squash a rinse under cool running water and scrub off any dirt with a vegetable brush or a clean kitchen towel. Pay extra attention to the base of the squash near the stem – that’s usually where the most dirt likes to hide. Pat it dry before you start slicing.

Start by cutting off both ends (top and bottom) of the butternut squash.

Stand butternut squash up on a firm flat surface (bottoms down), then slice it into half lengthwise.

Next, dig out all the seeds using a spoon.

How to roast butternut squash

Now that we have cut up the butternut squash, it’s time to prepare it for roasting.

Step 1: Arrange the squash

Place both halves of butternut squash face side up (skin side down) on a baking dish or sheet pan.

For easier cleanup, line with parchment paper.

Step 2: Brush with oil

Using a brush, brush olive oil onto the non-skin surfaces of both halves of butternut squash, including the hole where the seeds were dug out from.

Step 3: Season

Then sprinkle it generously with sea salt, black pepper and brown sugar.

Alternatively, you can toss the seasonings together in a large bowl before adding it to the butternut squash.

Step 4: Roast

Roast butternut squash in the oven at 400℉ for 45-60 minutes. Check at the 40-45 minute mark, especially if you are baking a small butternut squash. If not, you will most likely need close to an hour.

Step 5: Check for doneness

When done, butternut squash should be very soft and tender on the inside, and you should be able to scoop it out easily with a spoon (or fork – this is called “fork tender”). Use a spatula to lift the halves off the pan once they’ve cooled slightly.

And there you go – Whole Butternut Squash in all its glory.

Roasting butternut squash this way really brings out the natural sweetness from the butternut squash. It should be fork tender, soft and very flavorful.

Super simple. Super tasty. Super satisfying.

Variation and substitution

There are so many seasonings and spices you can add on when you roast butternut squash whole.

I like to have a savory and a sweet component because having both really brings out the flavors of the butternut squash. But other than that, have fun with it! Feel free to add additional flavors to make this recipe your own!

Here are some substitution for making whole roasted butternut squash:

maple syrup or honey instead of brown sugar
seasonings such as garlic or onion powder
herbs such as thyme, sage, rosemary, or parsley
adding some Fall flavors such as ground cinnamon, allspice, ground cloves or/and ground nutmeg
a sprinkle of grated parmesan cheese right when it comes out of the oven, for a savory, cheesy finish (a few readers have also had great luck with goat cheese or feta!)

Make Ahead, Storage, And Reheating

Make ahead: Roasted butternut squash is a great make-ahead side. Roast it up to a few days before you plan to serve it, then just reheat when you’re ready to eat.

Storage: Let the squash cool completely, then store it in an airtight container in the fridge for up to 4-5 days. You can leave it in halves or cut it into cubes first, whichever is easier for how you plan to use it later.

Freezer: Roasted squash freezes well too. Store it in an airtight container or freezer bag for up to 2-3 months – this is the better option if you’re cooking more than a few days ahead of time.

Reheating: Reheat in the oven until warmed through, or microwave in short bursts if you’re short on time. If it’s frozen, thaw it in the fridge overnight before reheating.

How to serve this butternut squash

This makes a wonderful side dish to many protein dishes such as:

Lemon Balsamic Chicken
Pork Tenderloin with Gravy
Restaurant Style Steak
Sheet Pan Oven Baked Sausage and Peppers
Honey Lemon Garlic Shrimp
Skillet Chicken with Blistered Tomatoes
Cheesy Tuna Casserole (by Love in my Oven)

In addition to sides, roasted squash make the best salad toppings. After roasting the whole squash, remove the skin and cut it into bite-sized (about 1 inch) cubes. Serve cubed butternut squash on top of your favorite salads, or toss it into a quinoa or grain bowl for an easy fall lunch.

BONUS: This is also a great way to get a butternut squash ready to be mashed up. Remove the skin and use a potato masher or electric mixer to smash butternut squash until smooth. With the seasonings added prior to baking, butternut squash should already be plenty flavorful, but you can always add more seasoning to mashed butternut squash if you like.

Ready. Set. Feast! 🧡

Tips and Tricks

Choosing good squash: Select a squash that feels heavy for its size, with a hard, blemish-free rind, to ensure it is ripe and flavorful.
Give it a scrub: Whole squash pick up a lot of dirt on the way to your kitchen, so rinse and scrub it well before cutting, especially around the base near the stem.
Safety first: Squash can be surprisingly tough to cut through. Use a sturdy, sharp knife when cutting the squash to avoid accidents; and, where possible, place squash flat-side down to slice through.
Microwave hack: Microwaving the whole squash for a minute or two can make it easier to slice in half. You can also nuke it for a little extra longer to cut down on overall time in the oven.
Skip the peeler: Since the squash roasts whole, skin and all, you won’t need a vegetable peeler for this recipe. Once it’s roasted, the skin peels away easily with just a spoon or your fingers.
Don’t skimp on the oil: A generous drizzle of olive oil across the cut surface helps the squash caramelize and get those crispy edges, so don’t be shy with it.
Easy cleanup: Line the baking dish/pan with parchment paper before placing butternut squash on top.
Prevent Burn: Cover squash with aluminum foil in the last few minutes of baking if you notice the tops are burning before they are tender.
Handle with care: Let the roasted squash cool for a few minutes before moving it, and use a sturdy spatula to lift the halves off the pan so the caramelized top stays intact.

Frequently Asked Questions

What other seasonings are good on butternut squash?

You can add other seasonings such as garlic or onion powder, or herbs such as thyme, sage and rosemary. For a smoky flavor, add smoked paprika or chili powder.

Can this recipe be made ahead of time?

Yes! Yes! Check out the Make Ahead, Storage, and Reheating section above for all the details on storing and reheating.

What can I serve alongside roasted butternut squash?

It pairs well with roasted chicken, turkey, or pork, and complements other fall dishes like cranberry sauce and green bean casserole.

Can I use butter?

Most definitely. Use melted butter in place of olive oil, and/or add some butter to the finished product to further enhance flavor.

Can I cook more than one squash at a time?

Yes, but make sure they are not overcrowded on the baking sheet to ensure even cooking. You may need to adjust the roasting time slightly. Consider baking for a longer time if oven is very packed.

How do I cut butternut squash more easily if it feels too hard to slice?

A few of you have asked about this in the comments, and it’s a really common sticking point! Poke a few holes in the squash with a fork, then microwave it for a couple of minutes to soften the skin before cutting. Always use a sturdy, sharp knife (some readers also swear by a two-handled “coup de legume” style knife for tough squash and other winter vegetables), and rest the squash flat-side down for stability while you cut.

Can I roast the squash whole first to make it easier to cut?

Yes! One reader shared this method in the comments, and it’s a great option if cutting a raw squash feels intimidating: roast the whole squash for about 25 minutes first to soften it up, then carefully slice it in half, scoop out the seeds, season, and roast for another 25-30 minutes to finish. It takes a bit longer overall, but the squash cuts like butter afterward.
