  • 4 pounds butternut squash peeled, seeded & cut into bite-size pieces
  • 2 tablespoons olive oil
  • Salt & pepper to taste
  • 1/4 cup butter
  • 1/4 teaspoon ground cinnamon optional
  • 1/4 teaspoon ground nutmeg optional


  • Preheat your oven to 400F and move the rack to the middle position.
  • Prep the squash. To easily peel the squash, I cut it into quarters and carefully use a knife to cut the peel off since it's very thick. Cut it into approximately 1.5" pieces.
  • Place the squash on a large baking sheet and toss it with the olive oil. Season generously with salt & pepper. Roast for 25-30 minutes or until it's very tender. I like to toss it halfway through baking for more even color.
  • Transfer the squash to a pot (I find this to be the most stable thing to use for mashing) and then add the butter, cinnamon, and nutmeg, and mash it using a hand-held potato masher. Really mash it (it takes more effort to get it smooth than with potatoes). Taste it and add more salt & pepper if needed. Once it's nice and smooth, transfer it into a serving bowl.


  • If you don't want to peel & cut up the squash into pieces, you can cut it into halves (lengthwise), scoop out the seeds, add a bit of butter to each half (where the seeds were) and roast it for about an hour. You then scoop out the flesh and mash it as the recipe indicates.
  • You can halve the recipe if 6-8 servings are too much (I usually buy two 2-pound squashes).
