Roasted Acorn Squash Slices are an easy, healthy side dish with only 3 ingredients! Fast enough for a weeknight side dish but fancy enough for a dinner party!
I make these roasted acorn squash slices at least once a week in the Winter when acorn squashes are at their most flavorful. Roasting the squash concentrates the naturally sweet flavor. A sprinkle of pumpkin pie spice highlights those sweet notes for the perfect winter dish! The spices pair beautifully with my Foolproof Rosemary Chicken or Spicy Peach Pork Chops!
Slicing the squash adds extra surface area for more browning and it allows them to cook faster. A dinner win-win! They can cook at any temperature between 350°F and 425°F, so you can easily prepare the rest of the meal at the same time or add them to your weekly meal prep like I do! I always make extra for lunches or my favorite roasted squash salad!

The ultimate guide to cooking slices of squash
Time needed: 20 minutes.
An altogether delightful and healthy way to make roasted acorn squash!
- Prep the squash slices
On a sturdy cutting board, slice off the top and bottom of the squash. Place cut side down on the cutting board and slice in half lengthwise exposing the seeds. Scoop out the seeds. Turn the squash center-side down on the cutting board and slice thin slices about 1 cm wide starting from one side and working across the whole squash like an arch.
- Spice the slices
Arrange squash flat on prepared baking sheets with some space in between to allow for even cooking and browning. Drizzle with all the olive oil, half the salt and half the pumpkin pie spice. Flip squash and repeat with remaining salt and spices.
- Roast the acorn squash
Bake in preheated oven at 350°F for 15-25 minutes or until the squash is tender and pierces easily with a fork.
Can you eat the skin on acorn squash?
The skin on acorn squash is edible, so be sure to wash it before slicing. I find that when roasted, I can’t even taste the skin on the roasted acorn squash and it generally cuts easily with a fork.
Can you eat acorn squash seeds?
You can absolutely eat acorn squash seeds! They are delightful roasted. To roast acorn squash seeds simply separate the seeds from the strings, toss in a little oil, salt and pepper and roast in a 350°F oven until golden brown.
- Acorn Squash: Choose an acorn squash that is firm and heavy for its size to make this roasted acorn squash. I think the smaller ones are in effect sweeter and have better flavor. If roasting multiple squash, try to choose ones that are similar in size so they roast in the same amount of time.
- Kosher Salt: Not only does the kosher salt heighten the flavor but it helps keep the squash tender. Don’t omit completely. Back it down to ½ teaspoon at the least.
- Pumpkin Pie Spice Mix: I’d recommend you use my pumpkin pie spice mix recipe. Not only is it great in savory dishes, it’s fine-tuned to also be delicious in biscotti, oatmeal, or cookies!
- Extra Virgin Olive Oil: Extra virgin olive oil goes through the least amount of processing of the olive oils, so it keeps some of its nutritional values! It has a gentle taste and helps veggies retain their moisture.
- Pumpkin Pie Spice: I use a few pinches of my pumpkin pie spice in my roasted acorn squash to highlight the natural sweetness, but you could use apple pie spice, cinnamon, or a grate of fresh nutmeg if you prefer.
- Kosher Salt: Don’t forget the salt! A pinch of kosher salt will heighten all those flavors and round out the dish.
- Acorn Squash: You could use this same recipe to cook butternut squash as an easier alternative to my spiced roasted butternut squash or it is also phenomenal with kabocha squash.

Chef Lindsey's Recipe Tips
To safely and easily slice acorn squash halves into slices I turn the squash center-side down on the cutting board to create a stable surface. Then starting on the right or left side I slice thin slices about 1 cm wide and work across the whole squash while holding the slices together for support. Think of it like the stones creating an arched doorway!

- Turn the squash center-side down on the cutting board and slice thin slices about 1 cm wide starting from one side and working across the whole squash like an arch. I like to hold the slices together to support the next ones for easy and safe slicing.
- I season my squash on the baking sheet but you could also do this in a bowl for a more even coating. Arrange squash flat on prepared baking sheets with some space in between to allow for even cooking and browning.

- Serve with or without the skin. The acorn squash skin becomes soft and tender when baked and I find it has no discernable flavor. After baking the flesh is easily scooped out if you don’t want the skin.
