Ingredients You’ll need

• 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 delicious. 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 the best 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.

How to make Mashed Butternut Squash

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.

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.

Ideas To Change Up this Squash Recipe

• 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 perfect 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.
