Butternut squash softens quickly in the microwave when cut into small cubes and covered with a damp paper towel. Learning how to cook butternut squash in microwave is a game-changer for busy weeknights. You get tender, sweet squash in under 10 minutes without heating up the oven.
This method works for meal prep, quick sides, or mashing into soups. No peeling required if you prefer, though we will cover both options. Let us get straight to the steps.
Why Microwave Butternut Squash
Microwaving is the fastest way to cook butternut squash. It saves time and energy compared to roasting or boiling. The squash retains more nutrients because it cooks quickly with minimal water.
You also avoid the hassle of peeling a tough raw squash. The microwave softens the skin so you can scoop out the flesh easily. This method is perfect for when you need cooked squash fast.
How To Cook Butternut Squash In Microwave
What You Will Need
- 1 medium butternut squash
- A sharp knife
- Cutting board
- Microwave-safe bowl or dish
- Damp paper towel
- Fork or spoon for testing doneness
Step 1: Prepare The Squash
Wash the butternut squash under running water. Dry it with a clean towel. Place the squash on a cutting board and cut off both ends with a sharp knife.
Slice the squash in half where the narrow neck meets the bulbous bottom. This makes it easier to handle. Stand each piece upright and slice off the skin from top to bottom if you want to peel it now.
If you prefer not to peel, you can cook the squash with skin on. The skin becomes tender and edible after microwaving, though some people find it chewy. For the softest result, peel first.
Step 2: Cut Into Small Cubes
Cut the peeled squash into cubes about 1 inch in size. Smaller cubes cook faster and more evenly. Try to keep all pieces similar in size so they finish at the same time.
If you left the skin on, cut the squash into cubes anyway. The skin will soften during cooking. For whole halves, you can skip cubing and microwave the halves directly, but cubes are faster.
Step 3: Place In A Bowl And Cover
Put the cubed squash into a microwave-safe bowl. Spread them in a single layer if possible. Do not overcrowd the bowl, as this leads to uneven cooking.
Cover the bowl with a damp paper towel. The moisture from the towel creates steam that helps cook the squash evenly. You can also use a microwave-safe lid with a vent, but the paper towel works best.
Step 4: Microwave On High
Set your microwave to high power. Cook the squash for 4 minutes for 1-inch cubes. If you are cooking a whole half, start with 6 minutes.
After the first round, carefully remove the bowl. The steam will be hot. Lift the paper towel away from your face to avoid burns. Stir the cubes with a fork to redistribute heat.
Continue cooking in 2-minute intervals until the squash is fork-tender. Total time is usually 6 to 8 minutes for cubes, depending on your microwave wattage. For halves, it may take 10 to 12 minutes.
Step 5: Test For Doneness
Pierce a cube with a fork. It should slide in easily with little resistance. The squash should be soft but not mushy. If it still feels firm, microwave for another 1 to 2 minutes.
Overcooking can make the squash watery or rubbery. Stop as soon as it is tender. Let the squash sit in the covered bowl for 1 minute after cooking. This allows the steam to finish the process.
Step 6: Use Or Store
Once cooked, you can use the squash immediately. Mash it with butter and salt for a quick side dish. Add it to salads, grain bowls, or soups. You can also blend it into smoothies or baby food.
For storage, let the squash cool completely. Transfer to an airtight container and refrigerate for up to 5 days. You can also freeze cooked squash in freezer bags for up to 3 months.
Tips For Best Results
Cut Evenly
Uniform cubes are key to even cooking. If some pieces are larger than others, they will not finish at the same time. Take an extra minute to cut consistent sizes.
Do Not Skip The Damp Towel
The damp paper towel is not optional. It traps steam and keeps the squash moist. Without it, the squash can dry out or cook unevenly. Replace the towel if it becomes too dry during cooking.
Adjust For Microwave Wattage
Microwaves vary in power. A 1200-watt microwave cooks faster than a 700-watt model. Start with the minimum time and add increments as needed. Check your microwave manual if unsure.
Use A Fork To Test
A fork is more reliable than a knife for testing doneness. The tines pierce easily when the squash is ready. If the fork bends or meets resistance, cook longer.
Variations To Try
Whole Butternut Squash In Microwave
You can cook a whole butternut squash in the microwave without cutting it first. Pierce the skin several times with a fork to let steam escape. Place the whole squash on a microwave-safe plate and cook for 5 minutes per pound.
Turn the squash halfway through cooking. Let it cool for a few minutes before cutting. The skin will be soft and easy to peel. This method is great for mashing or stuffing.
Butternut Squash Halves
Cut the squash in half lengthwise and scoop out the seeds. Place each half cut-side down in a microwave-safe dish with a little water. Cover with a damp paper towel and microwave for 8 to 12 minutes.
Test with a fork at the thickest part. When tender, scoop out the flesh with a spoon. This works well for stuffed squash or purees.
Seasoned Butternut Squash
Before microwaving, toss the cubes with olive oil, salt, pepper, and your favorite spices. Cinnamon, nutmeg, or paprika work well. The microwave will cook the squash and the seasonings will infuse.
Be careful not to add too much oil, as it can cause splattering. A teaspoon per cup of cubes is enough. You can also add a pat of butter after cooking for extra richness.
Common Mistakes To Avoid
- Cutting cubes too large: Big pieces take longer and cook unevenly.
- Skipping the cover: Dry squash leads to tough texture.
- Overcrowding the bowl: Steam cannot circulate, resulting in raw spots.
- Not stirring: Stagnant heat causes some pieces to overcook while others stay hard.
- Using metal bowls or foil: This can cause sparks and damage your microwave.
How To Use Cooked Butternut Squash
Simple Mashed Squash
Mash the cooked cubes with a fork or potato masher. Add butter, salt, and a pinch of black pepper. For sweetness, stir in a little maple syrup or brown sugar. Serve warm as a side dish.
Butternut Squash Soup
Blend the cooked squash with vegetable broth, garlic, and onion. Heat on the stove or in the microwave. Add cream or coconut milk for richness. Season with salt and thyme.
Quick Salad Addition
Add cooled squash cubes to salads with spinach, cranberries, and nuts. The sweet flavor pairs well with tangy vinaigrette. You can also mix it into grain salads with quinoa or farro.
Baby Food
Puree the cooked squash in a blender or food processor. Add water or breast milk to reach desired consistency. This makes a healthy first food for babies. Store in small containers for easy meals.
Freezer Meal Prep
Cook a large batch of squash cubes and freeze them in portion-sized bags. Use them later for quick soups, stews, or casseroles. Thaw in the microwave or add directly to hot dishes.
