How to Microwave Buttercup Squash

Why You Should Consider Microwaving Buttercup Squash

Microwave cooking has many benefits that make it a popular cooking method. Here are some reasons why you should consider microwaving your buttercup squash:


Microwaving your buttercup squash saves you time as it only takes a few minutes compared to other cooking methods such as baking or roasting which can take up to an hour.

Energy Efficient

Microwave ovens use less energy than other cooking methods as they do not heat up the entire kitchen but rather direct heat to the food.

Retains Nutrients

When food is microwaved, they retain more of their vitamins and minerals compared to other cooking methods where nutrients may be lost in the process.

Step-by-Step Guide on How To Microwave Buttercup Squash

Now that you know why microwaving your buttercup squash is a good idea, let’s move on to the steps on how to microwave buttercup squash:

Step 1: Prep Your Squash

Start by washing your buttercup squash under running water and then slice it in half lengthwise with a sharp knife. Use a spoon or an ice cream scoop and scrape out all the seeds from both halves of the flesh.

Step 2: Place Your Squash halves

Place each half of your prepared butternut squash face down one at a time into a deep microwave-safe dish filled with about two inches of water. The water creates steam which helps cook the flesh evenly.

Step 3: Set Microwave Time

Set your microwave on high power and cook the buttercup squash for 8-10 minutes. Once done, poke the flesh with a fork, if it’s soft, then it’s ready. If not, continue microwaving in 1 or 2 minute intervals until it becomes soft.

Step 4: Allow to Cool

Use oven mitts to remove the dish from the microwave oven and let it rest for a few minutes before handling. The squash will be very hot so use caution when removing them from the container.

Step 5: Scoop Out Squash Flesh

Hold each half of squash with an oven mitt or towel and use a spoon to scoop out its flesh that is now softened and cooked through. It should easily come away from the skin in one long sweep.

Precautions for Microwaving Buttercup Squash

Although microwaving is an easy cooking process that requires less attention than other baking or roasting methods, there are still some precautions you may want to take:

  • Always use microwave-safe dishes when microwaving buttercup squash.
  • Don’t leave your squash unattended while microwaving. Check on it periodically.
  • Be cautious when handling your buttercup squash after removing them from the microwave as they will be hot.

Factors Affecting Cooking Time

The cooking time of your buttercup squash in the microwave can vary depending on several factors such as:

  • The wattage of your microwave oven
  • The thickness and size of your butternut squash
  • Room temperature

It’s essential to consider these factors when estimating how long you should cook your buttercup squash.

Expert Tips for Perfectly Microwaving Buttercup Squash

Now that you know how to microwave buttercup squash let’s look at some expert tips that will help you achieve perfect results every time:

Use Puncture Marks

Before placing your prepared squash into the microwave oven, make several puncture marks on the squash with a fork. This will allow steam to escape and avoid excess pressure inside the squash.

Use Plastic Wrap to Cover

Covering the buttercup squash halves individually with plastic wrap before microwaving them will ensure that they cook evenly and are moist.

Fluff the Flesh Before Serving

Before serving your cooked buttercup squash, use a fork to fluff up and mash down some of its flesh. This will give it an appealing look and texture.

Advantages of Microwaving Buttercup Squash

In addition to time-saving, energy efficiency, and nutrition retention we mentioned earlier, there are other advantages of microwave cooking that you should consider:

  • Microwaved buttercup squash dishes can be prepared quickly for unexpected guests or last-minute meals.
  • Microwave cooking allows you to cook larger quantities than other cooking methods at once which is great for meal prepping.
  • Cooking with a microwave is safer than other methods as there’s little risk of burns or fires when using one.

Disadvantages of Microwaving Buttercup Squash

Here are some disadvantages of microwaving buttercup squash that you might want to know:

  • The texture may not be as crispy compared with baked or roasted vegetables.
  • You cannot achieve browning through microwaving which affects fusions such as gratins.
  • Some people believe that certain flavors may not come out perfectly when cooked in a microwave oven.

Frequently Asked Questions about Microwaving Buttercup Squash

Here are some common questions regarding microwaving buttercup squash:

Is it safe to microwave my butternut squash without cutting it first?

It is not recommended since there is no venting route for steam that could build-up inside. Therefore adding vents by cutting parts off first prevent internal pressure build-up while retaining flavor naturally.

Can my microwaved butternut squash still go bad?

Yes, even microwaved vegetable dishes can still go bad if not stored properly.

Should I cook my buttercup squash with a lid on or off?

It is advisable to cook your buttercup squash lid-off as it steams well this way.


As we’ve learned, microwaving your buttercup squash is a great way to save time, energy and retain more of its nutrition without affecting taste.

Take note of the precautions, factors that affect cooking time, and some expert tips for perfectly microwaving your butternut squash for meal prepping or any other dish.

With this knowledge in hand, you’ll be able to make delicious and healthy vegetable dishes in no time!
