Main ingredients in this butternut squash with rosemary

Butternut squash is abundant in most grocery stores during the fall and winter months. I recommend selecting the largest one you can find because squash does shrink down a fair bit when roasted. Or you can buy a couple of packages of pre-peeled and chopped butternut squash if your grocery store carries them (a nice shortcut if you’re swamped with other holiday tasks).

I used dried rosemary in this baked butternut squash, but you can substitute fresh if you prefer. And I used garlic powder to keep things really quick and easy but you can substitute fresh chopped garlic if you like, but in that case add the garlic at the halfway point when you’re flipping the squash. If you add fresh garlic at the beginning of the cooking process it may burn.

I used extra virgin olive oil in this dish, but any relatively neutral oil such as avocado oil is fine too.

How to make it

Start by preheating the oven to 400 degrees Fahrenheit, then peel, seed, and cut the butternut squash into 1.5 inch cubes (this doesn’t have to be exact. Rustic chunky shapes of a similar size are fine). Alternatively you can use pre-peeled, chopped butternut squash to save time if you prefer (measure out 5 cups if you go that route).

Next you’ll line a sheet pan with parchment paper, then add the butternut squash, olive oil, rosemary, garlic powder, salt, and pepper to the pan. Use your hands to toss and coat the squash in the oil and spices.

Bake at 400 degrees Fahrenheit for thirty minutes, then flip the squash so that it cooks and caramelizes evenly. Continue to bake for an additional thirty minutes or until the squash is fork-tender and golden brown around the edges.

Preparing this in advance

This rosemary butternut squash is perfect for the holidays and can be prepared up to three days in advance. After you’ve baked the squash, allow it to cool, then store it in an airtight container in the fridge. Transfer it to a baking dish and reheat it in the oven for 10-15 minutes or until your desired temperature is reached before serving.

Optional additions

To add an extra layer of flavor and texture to this butternut squash with rosemary, sprinkle on 1/2 cup of toasted chopped pecans immediately before serving. A garnish of finely chopped fresh chives is another nice addition.
