If you’re looking for an easy to make vegetable side dish, I’d like to share a delicious recipe for creamy mashed butternut squash. This recipe is a “copycat” recipe from Boston Market, a restaurant based in the United States. The restaurants were in over 1,110 locations back in the 1990’s. They’re still around these days serving delicious homestyle food, but now in only about 400 locations in the U.S. I found the recipe in one of my “Top Secret” cookbooks by author Todd Wilbur.

I’ve really grown to love butternut squash over the past 4-5 years! It is what is called a “winter squash”, but nowadays it is available year-round in the grocery store.  My family and I have enjoyed this veggie in Butternut Squash Soup with Bacon, Black Bean Butternut Squash Chili or Roasted Butternut Squash with Cranberries, Honey & Feta. I even enjoy making Glazed Butternut Squash in our Air Fryer!

Honestly, the hardest thing about this recipe is peeling the butternut squash, and that’s not hard at all! After the peeled and cubed squash has been steamed, it is mashed along with a few spices, brown sugar and butter, and served. It’s easy, and the finished creamy mashed butternut squash is delicious, and can be served alongside a number of main dishes. Here’s how to make it:

Prepare The Butternut Squash For Steaming

Use a vegetable peeler to remove all the peel from a medium-sized butternut squash. Slice off both ends. Cut the squash into two halves lengthwise, and then remove (and discard) the seeds and “pith”.

After all seeds have been removed, cut the entire squash into 1″ cubes. Try to cut them all about the same size, so they cook evenly while being steamed.

Steaming The Squash

Place the cubes in a steamer basket sitting in a large saucepan over boiling water (water about two inches deep). Cover the pan. Let the squash steam for about 30 minutes, OR until the squash is fork-tender. Once done, remove the steamer (and squash) from the pan.

Prepare Spice Mix While Squash Is Cooking

While the squash is steaming, get your spice mix and butter ready, so they are ready to ad to the squash once done and mashed. Melt the butter, and in a separate bowl, combine brown sugar, nutmeg, allspice, salt and pepper. Set aside.

Preparing Creamy Mashed Butternut Squash For Serving

Place the HOT, steamed butternut squash cubes into a large bowl. Use a potato masher to mash the squash, until this mixture becomes very smooth, and NOT lumpy!

Add the melted butter and the spice mix to the squash and continue mashing it all together. Once fully combined, let the squash sit for about 5 minutes to give the flavors of the spices a chance to permeate the squash.

After the creamy mashed butternut squash has “rested and mingled” for 5 minutes, give the squash a quick re-heating in a microwave  for about 1 minute. Now this delicious veggie dish is ready to serve.

Give it a quick taste, and add additional salt, if needed, to suit your own personal taste. The flavors of this creamy dish pair well with many main dishes, and I think you will really enjoy it!
