Oven Roasted Acorn Squash Slices
Roasted Acorn Squash Slices are the prettiest autumn side dish. With just a few ingredients and minimal prep, this stunning vegetable will be the star of your holiday table, but also perfect for a weeknight.
These Roasted Acorn Squash Slices are the perfect side dish
I’ve always believed that sometimes, the simplest dishes are not only the most flavorful, but the most beautiful as well. Just like my recipe for glazed carrots and balsamic green beans, today’s recipe is the epitome of that sentiment.
These roasted acorn squash slices on their own would be the perfect addition to a Thanksgiving salad, or all dressed up with parsley and pomegranate and added as a side dish to your Thanksgiving recipes binder (I’m not the only one with one, right?).
Roasted Acorn Squash Recipe Ingredients
- olive oil cooking spray – I find this the easiest way to prevent the squash slices from sticking to the pan. But if you don’t have spray, you can just use a thin layer of regular olive oil.
- acorn squash – two medium acorn squash should feed about 4 people as a side dish (or maybe a little more than that on Thanksgiving when there are lots of sides to fit onto your plate).
- salt and pepper – seasoning the roasted acorn squash slices is important for the best flavor.
- parsley – chopped fresh parsley adds a pretty touch any finished dish, whether it’s this squash or Cajun salmon pasta or Thanksgiving rice.
- pomegranate arils – these are a seasonal ingredient that add sweetness, crunch, color and beauty to this roasted acorn squash recipe. I also love them in Thanksgiving fruit salad, and sprinkled over vegan lentil curry and my lamb lollipop recipe
Can I use a different type of squash?
Yes! You can use the method from this roasted acorn squash recipe for a variety of hard winter squashes. Carnival squash and delicata squash are two other varieties that are perfect for this recipe (I actually have a separate post about roasted delicata squash).
If you come across sweet dumpling squash at your market, I recommend my sweet dumpling squash soup.

Best Seasoning for Acorn Squash
I think the best seasoning for acorn squash is simply salt and pepper, so the unique flavor of this seasonal ingredient shines.
But, if you’d like to add additional seasonings, dried rosemary, thyme or sage would be great. Ground cinnamon is also a nice pairing.
Best way to cut Acorn Squash
First, for this oven roasted acorn squash, you’ll want to select a large, very sharp knife. Be very careful. Make sure your cutting board is very stable (see my post about cutting board safety for some ideas on how to make this happen). Make sure you’re keeping your fingers tucked under and away from the knife.
A lot of oven roasted acorn squash recipes call for cutting the squash in half and then using a spoon to scoop out the pulp and seeds, but I think roasting sliced acorn squash is much easier.
So, with the squash on it’s side, use the knife to cut the squash crosswise into 1-inch slices. Then, you’ll be using some type of round cutter to cut the seeds and pulp out of the middle, in a perfect circle.
I was required to buy a set of round cutters (restaurant folk will refer to these as “ring molds”) for culinary school, so I use those here. You can also use a biscuit cutter, the end of a can or a jar, or simply use your knife to cut out the seedy part in the middle of each slice.
How to make Roasted Acorn Squash
- Preheat your oven to 425 degrees F. Roasting acorn squash slices at a high temperature allows the outer parts to caramelize and get extra yummy while the insides get tender.
- Grab two large rimmed baking pans (line them with foil for easy cleanup), and spray them with nonstick cooking spray. Just like with my roasted broccoli with lemon, two pans is better than one, because if the squash rings are too close to each other, they’ll steam rather than brown.
- Arrange the squash slices in a single layer on the two pans, lightly spray them with cooking spray and sprinkle them with salt and pepper.
- Roast for 30 minutes or until the squash slices are golden brown and tender, turning them over once, halfway through cooking.
How long to roast Acorn Squash
In a 425 degree F oven, acorn squash cut into 1-inch slices should take about 30 minutes to get golden brown and tender.
Check for doneness by inserting a fork or knife into the flesh. It should be tender and easily pierced.
Making Oven Roasted Acorn Squash in advance
Acorn squash can be roasted in advance to save time on busy days. Follow the roasting instructions in the recipe card below, then allow the squash to cool to room temperature before storing it in the fridge or freezer.
Acorn Squash Roasted tips and tricks for success
- UNIFORM SLICES – As you’re slicing the squash, it’s incredibly important to make the pieces as uniform in thickness as possible so that they all roast at the same rate.
- DON’T OVERCROWD – Make sure you use 2 roasting pans so that you don’t overcrowd a single plan. Leaving some space between the squash pieces allows for proper air circulation, which promotes even roasting.
- FLIP FOR EVEN COOKING – Flipping the squash slices halfway through cooking ensures that both sides are evenly roasted.
Do you leave skin on squash when roasting?
Yes, you can leave the skin on when roasting acorn squash. The skin is edible and will soften as it cooks, becoming tender and flavorful.
Leaving the skin on also saves you prep time, so it’s a win-win! Just to be sure to wash the squash throughly before slicing.
Does Acorn Squash cook the same as butternut squash?
While acorn squash and butternut squash are similar in many ways, they have a few differences. Acorn squash tends to be denser than butternut squash, which means it may cook slightly faster.
Also, while the skin of acorn squash is edible when roasted, butternut squash usually has a thicker, tougher skin that is usually peeled before cooking.
Storing and reheating Roasted Acorn Slices
Any leftover roasted acorn squash can be cooled to room temperature, then placed in an airtight container in the refrigerator for up to 4 days.
Reheat in a 350 degree oven until warmed through.
