For us, butternut squash is one of those veggies (like eggplant) that we don’t cook all that often. If you’re like me, you might wonder What to Do with Butternut Squash…

Butternut squash has a sweet, almost nutty flavor, kind of like a regular pumpkin and the seeds can be made the same way as roasted pumpkin seeds or saved to plant in the garden at springtime! Because of its mild flavor, butternut squash is also versatile roasted as a side vegetable, whipped up into a velvety butternut squash soup, or served cold like a salad! This recipe takes this sweet veggie and turns it into a simple side mash!

To Bake or To Steam?

Boiling/steaming butternut squash is the quicker method but it doesn’t have quite as much flavor. Baked Butternut Squash doesn’t absorb water and it caramelizes a bit adding another layer of flavor so that’s the method I use in this recipe. If you’re short on time, the squash can be cut into chunks and steamed about 15 minutes.

How to Cook Mashed Butternut Squash

Prep the Squash: Before cutting into the butternut squash, slice a very thin piece off the bottom (the widest part) and set it upright on a towel to keep it sturdy. Then cut it straight down the middle from the top with less worry! Once you have scooped the seeds out brush the inside with a portion of the melted butter and sprinkle with your choice of spices and brown sugar, if using.

Bake and Mash: Place butternut squash on a baking sheet, cut sides up, and bake until extra tender. When it’s done cooking and cool enough to handle, scoop out the flesh and place in a large mixing bowl! Mix the butternut squash to your desired consistency, slowly adding the cream and the remaining butter! Mmmm!

Before serving, season with salt and pepper. Or sprinkle with brown sugar for a final extra sweet touch!

This recipe is also easy to personalize to your taste! Mashed butternut squash with maple syrup will have a smoother texture than mashed butternut squash with brown sugar but both sweet and savory delicious! Did we mention irresistible too?!
