What goes in

• Butternut Squash – This winter squash is shaped like a long bell, narrow on the top and tapering out to a bell shape. It’s light tan in color; the inside flesh is a vibrant orange. Look for a large squash, about three to four pounds. If it’s larger or smaller, that’s okay; adjust the recipe ingredients accordingly.
• Olive Oil – A light coating of oil keeps the squash from sticking to the pan and helps it brown nicely as it roasts.
• Whole Milk – Whole milk makes this mashed butternut squash creamy and rich. You could use half-and-half for a little more decadence if you’re making this for a holiday. Really, any type of milk can be used.
• Melted Butter – Just like mashed potatoes, you totally need butter to bring out a standby in mashed butternut squash. If you’re making the sweet version of this recipe, try using brown butter for another layer of flavor.
• Kosher Salt – Salt enhances the overall flavor, keeping it from tasting flat.
• For Savory Mashed Butternut Squash – Smoked paprika, dried or fresh thyme, cayenne pepper.
• For Sweet Mashed Butternut Squash – Brown sugar, ground cinnamon and nutmeg.

Can we Use A Different Type of Squash?

Other winter squash varieties like buttercup, Hubbard, sugar pumpkin, or kabocha can be used in place of butternut squash. Honeynut squash is a newcomer that looks much like butternut squash and is a good substitute. The cooking method is the same; however, be sure to adjust the roasting time depending on the size of the squash.

How it comes together

Preheat your oven to 425°F; line a baking sheet with foil or parchment paper. Cut the squash and scoop out the seeds.

Oil the cut sides of the squash halves and season with salt. Place the squash on the baking sheet cut side down.

Roast the squash for 45 minutes to one hour, or until the squash is fork tender. To test it, simply poke a fork into the thickest part of the squash. If the fork goes in easily with little resistance, the squash is done.

Once the squash cools enough to handle without burning your fingers, scoop out the flesh with a spoon and transfer it to a large bowl.

Add the milk, butter, and the seasonings you choose.

Sweet version ingredients added. Savory version ingredients added.

Use a potato masher to mash the squash until you achieve the desired consistency. If you want the consistency to be ultra smooth and creamy, use an electric mixer.

Ways to change it

• Savory flavor ideas: Add roasted garlic, fresh rosemary or oregano, crispy fried sage leaves, caramelized onions, a swirl of balsamic syrup, or cooked crumbled bacon. (Try air fryer bacon. It’s reliable for small batches). Garnish the mashed squash with freshly grated Parmesan cheese or a sprinkle of maple chili roasted pepitas.
• Sweet flavor ideas: Add a sweetener of your choice. Maple syrup or honey add flavor as well as sweetness. Stir in vanilla bean paste, cinnamon, cardamon, ginger or nutmeg. A teaspoon or two of pumpkin pie spice or apple pie spice goes nicely. Garnish with spiced pecans or toasted walnuts.
• Make it vegan: Use non-dairy milk and vegan butter in place of the dairy.

Ways to serve it

Mashed butternut squash is the reliable side dish for any dinner. Serve it alongside proteins like roasted chicken breasts or air fryer pork chops, and other side dishes like sautéed spinach or roasted broccoli. This recipe is also great for Thanksgiving with other holiday favorites like cranberry sauce and crockpot mashed potatoes.

For a hearty vegetarian meal, serve the squash mash accompanied by rice pilaf, quinoa, or another grain, and sautéed spinach or sweet and sour German red cabbage.

Make Ahead Ideas

The great thing about mashed butternut squash is that you can make it ahead of time and store it in the refrigerator or freezer until you’re ready to serve it. It tastes great (no one will ever know that you made it ahead).

Keeping leftovers

Refrigerate/Freeze: Mashed butternut squash can be stored in an airtight container in the refrigerator for up to 4 days, or frozen for up to 3 months. Let frozen squash thaw in the refrigerator before reheating.

Reheat: Individual portions can be reheated in the microwave. If you want to reheat larger amounts, place the squash in a baking dish and cover it with foil. Let it come to room temperature for 30 minutes or so, then bake it at 350ºF for 30 minutes until heated through. Baking time depends on what size dish you use.
