Select your microwave wattage in the dropdown. The cook times in this recipe will automatically change accordingly.


To find your microwave’s wattage, look at the front panel, the side of the door, in the back, in the user manual, or Google the model number. If both an input and output wattage are listed, use the output.

Wattage translates to how powerful the microwave is. The higher the wattage, the faster your food will cook. The lower the wattage, the longer the cook time.

When in doubt, start with less time — you can always add more.

All You Need to Know About Microwaving Acorn Squash

How long does a winter squash take to cook in the microwave?

Ingredient Water Cook Time 19-20 mins
14 oz (400g) acorn squash 1 teaspoon 9 mins
28 oz (800g) acorn squash 2 teaspoons 11-12 mins
42 oz (1200g) acorn squash 1 tablespoon
Cook time calculated for 700w microwave

Winter squash such as kabocha, acorn, and even pumpkins take about 7-8 minutes to cook in the microwave. Cook times can also depend on the size and starch levels of the squash. When cooking larger chunks, consider adding more time or poking the surface with a fork to better distribute heat.

How to tell when winter squash is cooked through?

All winter squashes are typically ready when a fork easily pierces the surface of the squash. If there is no resistance, the squash should be cooked through. If it’s difficult to pierce with a fork, continue to cook in the microwave for an additional 2-3 minutes.

How to freeze a microwaved acorn or kabocha squash?

Like most frozen vegetables, winter squash needs to be cooked before freezing. Once cooked, allow them to cool, then pop them on a tray into the freezer, and when solid (about 6-8 hours later), transfer to a freezer-safe storage bag. Pop in the freezer and store for 1-2 months.

How to reheat a microwaved acorn or kabocha squash?

To reheat, simply place the chunks back in the Anyday and microwave for 2-3 minutes, or until warmed through.

What’s the healthiest way to cook butternut squash?

Steaming is the healthiest way to cook winter squash. Steaming it in the microwave cooks squash quickly and easily, with no pot of water to boil or pan to clean up later. By steaming the squash in its moisture, you’re keeping more nutrients inside of the vegetable.
