Ingredients You’ll Need
This is one of those simple, flavor-forward recipes that feels comforting and elegant, yet comes together with everyday ingredients. Here’s what you’ll need to make this oven roasted butternut squash:
- Butternut squash: This sweet, nutty winter squash becomes beautifully tender on the inside and caramelized on the edges when roasted. Look for one with firm skin and rich, deep orange flesh.
- Avocado oil: A high-heat oil that’s perfect for roasting. It adds richness and helps crisp the edges of the squash without overpowering the flavor. Look for cold-pressed avocado oil near other cooking oils.
- Fresh herbs (rosemary, thyme & sage): This trio adds earthy, woodsy, and slightly peppery notes that take the flavor to the next level. Mince the rosemary and sage, and simply strip the thyme leaves from the stems. Find it in the fresh herb section, or grow your own for easy snipping.
- Garlic cloves: Fresh minced garlic adds a savory base note and depth of flavor. As it roasts, it mellows and sweetens, blending beautifully with the herbs and squash. Use fresh cloves for the best flavor and aroma, usually found near onions and shallots.

How to Make Roasted Butternut Squash
Making roasted butternut squash is incredibly simple and so rewarding. With just a few steps and wholesome ingredients, you’ll have a flavorful, golden side dish that’s perfect for fall dinners, meal prep, or vegan Thanksgiving spreads.
Prepping Butternut Squash
Since this roasted squash needs the squash peeled and cubed, let’s talk about the easiest way to get it done without breaking a sweat (or a peeler). Butternut squash can be a bit of a beast to prep—hard skin, odd shape, slippery once peeled, so having a game plan makes all the difference. Here’s how to peel, slice, and cube it safely:
- Carefully remove the skin from the butternut squash using a sturdy vegetable peeler.
- 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.
- Take each squash half and slice it into long, even sticks.
- Gather the squash sticks and proceed to cube the whole squash.
- Collect all the butternut squash cubes in a bowl, then move on to prepping the remaining ingredients for your roasted butternut squash.
Making Butternut Squash
Now that your butternut squash is prepped and chopped, it’s time to turn those golden cubes into something truly crave-worthy. Roasting is where the magic happens—bringing out rich, nutty notes and softening the squash to melt-in-your-mouth perfection. Let’s walk through exactly how to make roasted butternut squash:
- Grab your cutting board and finely chop the garlic and fresh herbs.
- Sprinkle the chopped garlic and herbs evenly over the cubed butternut squash.
- Pour a light drizzle of avocado oil over the squash cubes.
- Grab a large spoon and gently toss the squash, garlic, herbs, and oil until everything’s evenly coated.
- Line a baking tray with parchment paper, then pour your squash mixture on top.
- Spread it out evenly so everything is well-layered.
- Roast the squash for 15-20 minutes in the oven. You want the cubes to be fork-tender and even slightly browned on the outside.
- Remove it from the oven and transfer to a dish for serving.
Tip for Easy Squash Cutting
Butternut squash can be tough to cut. Make sure your knife is sharp and your cutting board is secure, use a damp towel underneath to keep it from slipping. Always cut off the stem and base first to create a flat surface.
Easy Swaps and Add-Ins
If you’re using up what’s in your fridge or want to change up the flavor, these simple swaps and delicious add-ins make it easy to keep the dish fresh and exciting:
- Squash swap: Don’t have butternut squash? You can substitute with acorn squash, delicata, or even sweet potatoes. Just aim for similar-sized cubes and adjust roasting time slightly if needed.
- Oil options: If you’re out of avocado oil, go with olive oil, melted coconut oil, or ghee. They’ll still give you that golden, crispy roast while adding their own subtle flavor.
- Herb flexibility: Fresh herbs are ideal, but dried ones work too! Use about ⅓ of the amount if swapping in dried rosemary, thyme, or sage. You can also try Italian seasoning for an easy shortcut.
- Sweet twist: For a cozy, sweet-savory flavor, add a light drizzle of maple syrup or a sprinkle of cinnamon before roasting. It’s perfect for fall and holiday meals.
- Spice it up: Want more heat? Add a pinch of cayenne pepper, crushed red pepper flakes, or smoked paprika to the seasoning mix for a little extra kick.
- Make it a meal: Turn it into a hearty main by adding roasted chickpeas, quinoa, or farro. You can also toss the squash into grain bowls, pair it with a simple green salad, or serve alongside your favorite protein.

Common Questions
Butternut squash cubes typically roast in the oven at 400°F (200°C) for 20 to 25 minutes, or until they’re fork-tender and golden brown around the edges. For extra caramelization, you can broil them for an additional 2–4 minutes at the end, just keep a close eye to prevent burning.
For cubed roasted butternut squash, it’s best to peel the butternut squash before roasting. The skin can be quite tough and doesn’t soften enough in the oven when roasting cubes. Use a sharp vegetable peeler for easiest removal. However, if you’re roasting squash halves to scoop out the flesh later, you can leave the peel on and remove it after roasting.
Butternut squash pairs beautifully with both savory and sweet flavors. For a savory blend, try garlic, rosemary, thyme, sage, sea salt, and black pepper. For a slightly sweet twist, add a dash of cinnamon or nutmeg, or a light drizzle of maple syrup before roasting. A sprinkle of smoked paprika or red pepper flakes also adds a nice kick if you like a little heat.

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