An easy recipe for mashed butternut squash. Cook the squash in the microwave, then add butter, Parmesan, salt and garlic. Delicious!
Delightfully buttery and cheesy, and a better choice than potatoes, mashed butternut squash is one of my favorite substitutes for the starchy “real thing.”
Even my picky kids really like this recipe. They like it better than roasted butternut squash, which my husband and I actually prefer.
The ingredients you’ll need
The list of ingredients for this recipe is delightfully short. Here’s what you’ll need (the exact amounts are listed in the recipe card below):
Butternut squash: Peeled and cubed. I make life easy by buying it pre-cubed, either at Whole Foods or at the supermarket.
Butter: I use unsalted butter, but salted butter would probably work too.
Grated Parmesan cheese: Make sure you use finely grated cheese and not coarsely shredded.
Kosher salt: If using fine salt, you should reduce the amount you use, or the dish could end up too salty.
Minced garlic: You can use 1/2 teaspoon of garlic powder instead of using fresh garlic.
How to make mashed butternut squash
I use the food processor to achieve a smooth mash. But you can use a potato masher or even a fork if you don’t mind some elbow grease and slightly lumpier consistency.
The combination of using the microwave to cook the squash and then using the food processor to prepare the mash makes this a truly easy recipe.
Scroll down to the recipe card for the detailed instructions. Here are the basic steps:
1. You start by microwaving the squash cubes until tender. This is easy to do: you place them in a large microwave-safe bowl. Add 1/2 cup water, cover and microwave for 15 minutes, until tender. Then you drain them.
2. Add the cooked squash and the remaining ingredients to your food processor bowl and process until smooth. This should take 1-2 minutes, and you might need to stop and scrape the sides with a rubber spatula midway through processing.
How to serve mashed butternut squash
This is a very versatile side dish that truly goes with anything. I often serve it with one of the following main dishes:
A sweet alternative to the savory recipe
I’m not a fan of making a sweet mash. I prefer my side dishes savory. But if you’d like to try a sweet version of this recipe, simply omit the salt, garlic, and Parmesan. Then add a tablespoon of honey or maple syrup to the mash and process as usual.
What about leftovers?
If you have any leftovers of this mashed butternut squash recipe, they should keep well in the fridge, in an airtight container, for 3-4 days.
Simply reheat them in the microwave, covered, on 50% power prior to enjoying.
