Quick Acorn Squash Recipe

The one thing I have disliked about Acorn squash is that it can take a long time to cook if you want to bake it. It will take a little over an hour.

So I was reading one of my new cookbooks and it suggested microwaving the squash and then popping it under the broiler. And you know what? It worked. It worked wonderfully. Actually, I was amazed at the suggestion because this meant you can have an acorn squash in a reasonable amount of time.

With this microwave whole acorn squash recipe, you no longer have to wait a long time to enjoy this tasty winter squash. When using the microwave you can make acorn squash with brown sugar topping in under 20 minutes.

What Does Acorn Squash Taste Like?

Acorn squash is not something you see people making often. However, with this recipe where you can cook the acorn squash in the microwave, that might change things a bit. One of the reasons might be that people don’t know what it tastes like.

It has a light, refreshing, yet not overpowering nutty taste with a little bit of sweetness as well. It does have a nice buttery taste when baked too. Some might find plain acorn squash a little bland, but not when paired with my pumpkin pie butter sauce.

Ingredients for Microwave Acorn Squash

Aside from the acorn squash, you should have most of the ingredients in your pantry. Here’s a list of what you need:

  • Acorn squash
  • Butter
  • Brown sugar
  • Pumpkin pie spice
  • Salt

How to Pick Acorn Squash

Acorn squash may not be a regular item you buy at the grocery store so it might be difficult to know what makes a good acorn squash.

Look for the acorn squash that is free of blemishes and soft spots. The squash is ripe when it is dark green. A rind that is shiny can mean that the fruit was picked before it was fully ripe.

Next, look at the finish of the acorn. Does it have a waxy or matte look to it? You will want to find the one that has a matte look. Waxier-looking squash means that it was picked before they were ready to harvest.

Lastly, make sure the outside of the acorn squash as a whole looks okay. You don’t want one that has a lot of gross blemishes and soft spots on it. It could be it is past the point of being ripe and no longer edible.

Acorn squash should be stored in a single layer and not stacked on top of one another. It can be stored at room temperature for up to three months in a dark area.

How to Cut Acorn Squash

For this microwaved acorn squash recipe, you will need to cut the squash in half from the stem to the bottom of the squash. This will give you a nice little center for the butter to settle when it is cooked.

Place the acorn squash on a cutting board. Use a sharp, sturdy chef knife to slice it in half.

How to Make Your Own Pumpkin Pie Spice

Now that autumn is upon us, all of the apple and pumpkin recipes are out so you will want to either make your own pumpkin pie spice or buy it if you don’t already have it.

For this squash recipe, I use a delightful pumpkin pie spice butter sauce and it has pumpkin pie spice in it. If you do not have any yet, it is actually quite simple to make your own.

I have a great recipe for homemade pumpkin pie spice that you could give a try. You can store the remaining spice mix for another recipe.

    I’ve cooked Acorn squash like this for years. I don’t use pumpkin pie spice but use apple pie spice and a dash more cinnamon. The brown sugar can also be replace with a thick brushing of maple syrup. For ease in cutting one, I use an ice pick and prick every 1 -1 1/2″ around it and it makes it easier to keep a straight cut. Don’t discard those seeds! Clean them and roast them like pumpkin seeds and spaghetti squash seeds.

    I’ve made acorn squash (our favorite) for years in the microwave. To the above recipe I add chopped apples. . .just mix with the brown sugar and a little cinnamon, then top with butter. But I DO NOT broil.
