How long do you microwave a butternut squash depends on its size, but generally, a whole butternut squash takes about 10 to 15 minutes on high power.
If you’re microwaving it cut in half, that time drops to around 7 to 10 minutes.
The exact time you microwave a butternut squash also depends on your microwave’s wattage, so always check for doneness.
In this post, we’ll break down exactly how long to microwave a butternut squash, whether whole or halved, plus tips to get it perfectly tender every time.
Let’s dive in.
How Long Do You Microwave a Butternut Squash?
How long you microwave a butternut squash isn’t a one-size-fits-all answer, but here’s a solid rule of thumb to follow.
A whole butternut squash (about 2 to 3 pounds) usually needs 10 to 15 minutes on high.
A halved butternut squash takes closer to 7 to 10 minutes.
Cubed butternut squash is the fastest, needing only 4 to 6 minutes.
The best way to know when you’ve microwaved a butternut squash long enough is to pierce it with a fork or knife.
If the blade slides in easily with no resistance, it’s done.
If it’s still firm, keep microwaving in 1-minute bursts until it’s tender.
Remember, microwaves vary in power, so a 700-watt microwave will take longer than a 1200-watt one.
1. Microwaving a Whole Butternut Squash
Microwaving a whole butternut squash is the easiest method because there’s no cutting involved before it softens.
Start by poking several holes all over the squash with a sharp knife or fork.
This step is crucial because it lets steam escape and prevents the squash from bursting.
Place the whole butternut squash on a microwave-safe plate and microwave on high for 10 minutes.
Flip it over carefully using oven mitts, then microwave for another 5 minutes.
Let it rest for 5 minutes before cutting, and you’ll find the skin peels off effortlessly.
2. Microwaving a Halved Butternut Squash
If you want to microwave a butternut squash that’s already halved, the process is even quicker.
Cut the squash lengthwise, scoop out the seeds, and place both halves face-down on a microwave-safe dish.
Add about 2 tablespoons of water to the dish to create steam.
Microwave on high for 7 to 10 minutes, depending on the size of the halves.
You’ll know it’s ready when the flesh is fork-tender and the edges start to pull away from the skin.
This method is perfect when you plan to mash, puree, or cube the squash for recipes.
3. Microwaving Cubed Butternut Squash
Cubed butternut squash cooks the fastest, making it ideal for quick weeknight meals.
Peel and cube the squash into 1-inch pieces, then place them in a microwave-safe bowl.
Add 2 to 3 tablespoons of water, cover with a lid or microwave-safe plate, and microwave on high for 4 to 6 minutes.
Stir halfway through to ensure even cooking.
When you microwave butternut squash in cubes, you can have tender, ready-to-eat squash in under 10 minutes.
Tips for Microwaving Butternut Squash Perfectly
Getting the timing right is important, but these tips will help you microwave a butternut squash like a pro.
1. Always Pierce Whole Squash First
Never skip piercing a whole butternut squash before microwaving it.
Trapped steam inside can cause it to explode, making a huge mess in your microwave.
A few quick pokes with a knife are all it takes to keep things safe.
2. Use a Microwave-Safe Cover
When you microwave butternut squash halves or cubes, cover them with a lid or plate.
This traps steam and helps the squash cook faster and more evenly.
Just make sure the cover has a vent so pressure doesn’t build up.
3. Let It Rest Before Handling
After you microwave a butternut squash, let it sit for 5 minutes.
The residual heat continues cooking the inside while the outside cools down enough to handle.
This resting period also makes the skin easier to remove.
4. Adjust Time Based on Wattage
If your microwave is lower wattage, expect to add a few extra minutes.
A 700-watt microwave might need 15 to 20 minutes for a whole squash, while a 1200-watt one could finish in 8 to 10 minutes.
Always start with the lower end of the time range and add more as needed.
How Long Do You Microwave a Butternut Squash for Soft, Tender Results?
How long do you microwave a butternut squash for soft, tender results?
The answer is simple: microwave a whole butternut squash for 10 to 15 minutes, halves for 7 to 10 minutes, and cubes for 4 to 6 minutes.
Always pierce whole squash, add water when cooking halves or cubes, and check for fork-tenderness before stopping.
When you microwave a butternut squash using these guidelines, you’ll get perfectly cooked squash every single time.
So next time you’re short on time and craving something hearty, just remember how long to microwave a butternut squash and you’re good to go.
