I know many people think of pumpkins when talking about seasonal squash. Yet butternut squash is a warm, often less expensive way to enjoy buttery, slightly sweet seasonal produce and it is a little easier to manage.

You can roast it whole, halved or cubed. I like cubed the best since it ensures that each piece is crispy and seasoned to perfection.

Roasted Squash Ingredients

I love a simple side dish that highlights the natural flavor of the vegetable. I need something easy if I’m using this for a holiday gathering. Here’s what I use in roasted cubed butternut squash.

ingredients for roasting squash including avocado oil, salt, pepper, garlic cloves and fresh herbs.
  • Butternut Squash: I love getting these in my produce box or grabbing one at a local market. When they are in season, they are a great, inexpensive squash option!
  • Avocado Oil: I like using avocado oil instead of olive oil in this recipe as it can withstand a higher temperature without burning. Feel free to use the oil of your choice.
  • Salt and Pepper: Start with a light seasoning of each and let your guests add more if needed.
  • Fresh Herbs: Fresh herbs outshine dried, and rosemary, thyme and sage are ones I love to showcase with squash.
  • Garlic Cloves: Minced garlic roasts nicely along with the squash, helping bring a bold warmth to the slight sweetness of the main ingredient.

Alternative Flavor Combinations

One great thing about this roasted butternut squash recipe is its versatility. Whether you want sweet or savory, my base recipe accommodates any flavor preference.

Sweet Squash: Start with cubed butternut squash and mix well with melted coconut oil, maple syrup and cinnamon. Spread evenly in a pan and bake at 400°F for 15 minutes. Carefully remove the pan and top with pecans and marshmallows and turn to broil for 2-3 minutes, watching closely so that the top browns instead of burns.

Spicy Squash: Cube butternut squash then mix well with avocado oil, chili powder, cumin, salt and pepper. Bake as directed below then carefully remove from oven and stir. Return to oven to broil for 3-5 minutes for crispy cubes. Use in tacos with coleslaw, or serve with tortilla chips and black beans.

How to Make Roasted Cubed Butternut Squash

I avoided butternut squash because I wasn’t sure how to prep or cook it. Then I had it at a restaurant one Autumn and I was hooked. It’s slightly sweet, warm and buttery, and can be used in a variety of dishes. So I quickly learned how to properly prepare it to enjoy whenever it’s in season.

See the Prep Tips section for step-by-step instructions (and photos!) on how to peel and cube this unique plant, and read on for how to roast it to perfection.

Step 1: Peel and cube the butternut squash. Chop the fresh herbs and mince the garlic cloves.

Step 2: In a large bowl, combine the cubed squash, avocado oil and all seasonings. Toss well to coat evenly. The best roasted cubed butternut squash has an even coating of oil, so don’t just quickly toss and be done! Make sure all the cubes are evenly coated for maximum flavor and ease of roasting.

Step 3: Preheat the oven to 400° F and line a baking sheet with parchment paper. This keeps the squash from sticking to the bottom of your pan. You can also line your baking sheet with a silicone baking mat, yet I would also increase the baking temp to 415° or 425° F to accommodate the thicker sheet. Roast the squash for 15-20 minutes. You want the cubes to be fork-tender and even slightly browned on the outside.

If you’re looking for super crispy cubes then once they are completely baked, switch your oven to broil and broil for 3-5 minutes to caramelize the butternut squash. Watch closely to avoid burning the squash!

Once the cubed squash is completely roasted, remove it from the oven and top it with fresh parsley. You can serve warm, room temp, or even cold, depending on your preference. This reheats nicely in the toaster oven or works great as cold leftovers.

Prep Tips

Since my roasted butternut squash recipe needs peeled and cubed, let’s dive into the best way to accomplish this. I don’t know if you’ve ever peeled a butternut squash, but when I do, my hands blister. It’s called contact dermatitis and while it doesn’t affect everyone, I recommend getting wearing some gloves while you handle raw butternut squash to avoid any irritation.

Now that we’re properly covered, let’s get prepping!

Step 1: Use a vegetable peeler and peel the whole butternut squash lengthwise.

Step 2: Once peeled, use a large knife and carefully cut off the top of the squash as well as the bulbous part. Cut the bulbous part in half and scoop out the seeds and any stringy bits.

Step 3: Cut the long neck portion in half, then proceed to cube the whole squash (both the neck and the bulbous portions).

Once this is complete then you can move on to chopping up the fresh herbs and garlic cloves.

Butternut Squash FAQs

How long does it take for butternut squash to soften in the oven?

I roast my cubed squash at 400° F for 15-20 minutes. If I want to keep the cubes softer, I then remove them from the oven. If I want crispy squash I will gently stir up the cubes, then return to oven and broil for 3-5 minutes to caramelize the edges.

Do you need to peel butternut squash before roasting?

If you are cubing your squash then yes! Peel, remove the seeds and dice the squash before baking. If you are pureeing the squash or want it soft, then you can roast simply by cutting the squash in half lengthwise, then scoop out the seeds. Once baked you can scoop the flesh out of the skin.

What is the best way to cube butternut squash?

I start by peeling the whole squash. Once peeled, I use a large cutting board and a large knife to carefully cut the squash in half lengthwise. Scoop out the seeds from the bulbous part, then cut each half into sections to cube.

    This is a great side dish! Do you ever find the herbs get burnt in the oven, or do they stay pretty fresh?

    1. Hey there Erin, these herbs are going to get perfectly cooked along with your butternut squash to ensure flavor. My only cautions would be to follow the recipe as directed and to keep your baking dish centered in your oven (if you have an electric oven) so that your dish isn’t too close to the heating element. Other than that – enjoy this delicious Autumn staple!
