Preparing acorn squash for cooking

If cooking the acorn squash in the oven or an air fryer, follow these steps to prepare the squash before roasting. If cooking the squash in the microwave, you’ll want to keep it whole and follow the directions in the next section.

Each of these methods were tested using an average size squash, 1 ½ – 2 pounds in size. If the squash you have is smaller or larger, you may have to adjust the cooking times either up or down.

1. Cut the acorn squash in half from stem to root. The skin on acorn squash is very thin so it’s much easier to cut than other squash, like spaghetti squash.
2. Use a fork to remove the seeds from the middle of the squash.
3. Brush the flesh of the squash with olive oil, then season with salt. Other seasonings can also be added at this time. More on that below.

How to cook it in an air fryer

1. After you’ve followed the steps above to prepare the squash, place it cut side up in an air fryer.
2. Cook at 400°F for 20 minutes.

How to cook it in the microwave

1. Use a fork to poke holes all over the squashto release steam as it cooks in the microwave.
2. Place the squash on a microwave-safe plate. Microwave for 4 minutes, use tongs or an oven mitt to flip the squash over on the plate. Microwave for an additional 4 minutes.
3. Remove from the microwave and slice in half from root to stem. Use a fork to remove the seeds from the middle of the squash. Season and dig in, or use in your favorite acorn squash recipe.

How to roast it in the oven

1. Follow the instructions above to prepare the squash, then place it cut side up on a foil-lined baking sheet.
2. Roast in a preheated 400°F oven for 35-45 minutes.

What’s the best way to cook acorn squash

• Fastest: the microwave only takes 8 minutes to cook a whole acorn squash, making it the fastest method. If you’re in a hurry, this is the method I’d recommend.
• Best texture: it’s a tie, between the air fryer and oven. The texture of acorn squash cooked in both of these appliances is very similar. It’s tender, with a slightly crispy, caramelized texture on the top layer of squash.
• Best overall: if you’re only cooking one acorn squash, I’d recommend the air fryer. It cooks in almost half the time as the oven and the taste and texture are almost identical to the squash cooked in the oven. If you’re roasting more than one squash, I would recommend the oven for the best texture and the ability to cook several squash at a time.

Pro tips

• You’ll know when the squash is done when you can easily insert a fork in the flesh.You want it tender, yet not mushy. If the squash is already cut in half, you can easily test if it is done by sticking a fork in the flesh of the squash. If it’s fork-tender, it’s done cooking and ready to eat.
• To avoid watery acorn squash, do not over cook it. Overcooked squash will become watery and mushy. Salting the squash before roasting it also helps to pull out some of the moisture to avoid watery squash.
• You do not need topeel acorn squash before cooking, as the flesh will easily scoop out of the squash once it’s cooked. You can also easily peel the skin from the squash, once it’s cooled to the touch, or by using heat-proof gloves.
• Use something sharp to deseed the squash. I like using a fork to scrape out the seeds, however a grapefruit spoon is another helpful tool.
• If you are having trouble cutting the squash in half, try this trick. Use a sharp knife to carefully pop off the stem by wedging the tip of the knife under and prying it up, or simply slice off the top of the acorn squash. Once the top of the squash is removed, place the squash on a cutting board cut-side down, this allows you to push the knife through with more steadiness.

Storing and freezing

Once the squash is cooked and the flesh is removed from the skin, you can store it in the refrigerator or freezer for leftovers or meal prep.

• Let the squash cool to room temperature.
• Seal it in an airtight container.
• Refrigerate for up to 7 days.
• You can also freeze cooked acorn squash for up to 8 months.
  • It is best to vacuum seal to avoid freezer burn.
  • If you don’t have a vacuum sealer, simply place it in a freezer safe zip-top bag and squeeze out as much air as possible before sealing.
