🛒 Ingredients

acorn squash
olive oil
garlic: fresh cloves
Parmesan: Parmigiano Reggiano has the best flavour
fresh herbs

Acorn squash has a slightly sweet flavour and, when cut crosswise, forms appealing, almost flower-shaped slices. Sometimes, acorn squash can be slightly bland, so it needs bold flavours to complement its natural sweetness and creamy texture.

In this recipe, Parmesan cheese add a subtle saltiness to acorn squash's natural sweetness. Garlic and Parmesan are a killer combo and adding fresh herbs like rosemary, thyme or sage adds flavour and interest, too.

Depending on your squash and your family's tastes, you may want to add a little heat with some dried red pepper flakes. They're optional, but very good if you're like me and like flavours with a little kick.

Tips for making Garlic Parmesan Roasted Acorn Squash

Keep it simple and toss everything together in a large bowl once you have the slices cut.

First, toss the squash with olive oil, lots of fresh minced garlic, finely grated Parmigiano Reggiano, fresh chopped herbs, and sea salt and pepper.

Crispy edges are the feature we all crave. (Well, I do anyway!) I like to heat my baking sheet in the oven for a few minutes first, so when the squash hits the pan, it sizzles and seals in all that wonderful flavour.

Roast in a hot oven until tender, then place under the broiler for a few minutes to brown it a little more.

And finally, serve with more fresh chopped herbs of your choice. I like rosemary, but thyme and sage pair well with acorn squash, too.

Frequently asked questions

How do I choose an acorn squash?

When faced with a large bin full of squash at your farmers' market, how do you know which will be the best acorn squash to choose?

Look for ones that have smooth rind with no soft spots, cracks, or mold. The rind should be dull. If it's shiny, it may mean it was picked too early and will not have the characteristic sweet flavour.

The skin should be almost all dark green. If it has a lot of orange, it indicates it is overripe and may be dry and stringy. In my experience, the smaller squash (about 1 to 3 pounds) are best. If they're larger, they may be dry. Occasionally, you can find other varieties, like this white acorn squash in the photo.

How do you slice an acorn squash?

Use a sharp knife and a sturdy cutting board.
First slice off the stem end and tips.
Next, set the squash upright and slice through the middle from the stem end to the base.
Remove the seeds with a spoon and either save for roasting or add to your compost.
Place the squash cut-side down on the cutting board and cut into slices about ¾ inch thick.

Do I have to peel an acorn squash?

The skin of an acorn squash is edible. Sometimes smaller squash have thin and more tender skin.
I leave the skin on because it helps to maintain the shape of the slices. If you don't want to eat it, it slips off easily once cooked.

What is the best way to store acorn squash?

A cool, dry place is the best place to store squash. Acorn squash will last for 5 to 8 weeks. Don't store them in the refrigerator for more than a week or two as the outer skin may become too moist and rot.
