Roasted whole butternut squash is an easy way to enjoy the delicious winter squash. Simply slice in half, then bake until tender. A maple cinnamon glaze and chopped nuts add a touch of sweetness to each serving.

One of the easiest ways to prepare butternut squash is to roast it whole. No peeling, just cut in half, remove the seeds, and bake. It makes for a stunning and healthy side dish. To add layers of flavor with minimal effort, I roast the halves flesh-side down to boost the browning on the surface.

You can simply enjoy the sweet and nutty flesh with just salt and pepper. However, I like to make it even tastier. A brush of sticky maple syrup and a sprinkle of bold cinnamon and nutmeg create delicious caramel notes. Slice it up into individual servings, scoop out a few spoonfuls, or stuff it to make an edible bowl.

Prepare the squash for roasting

The most challenging step in this recipe is cutting the squash. Make sure to trim off the stem and bottoms first. This process makes it much easier to slice down the center.

Then use a gentle rocking motion with a sharp knife to cut it in half lengthwise. Use a spoon to scoop out the seeds. If you like, you can clean and dry them, and eat them like roasted pumpkin seeds as a healthy snack.

Roast the squash

Brushing olive oil over the flesh of a butternut squash.

Brush the flesh with olive oil before roasting. The fat heats up and helps fry the surface, creating a golden brown color loaded with flavor. I cook the squash halves cut-side down until I can easily pierce it with a knife. It’s ready to enjoy, but let’s boost the flavor up a notch with a glaze.

Add a flavorful glaze

Brushing a maple glaze over roasted butternut squash.

Combine maple syrup, cinnamon, and nutmeg. Generously brush it on top, then roast until it’s bubbly and caramelized. Giving the oven about 10 minutes helps to evaporate the syrup’s moisture and concentrates the toffee-like flavors onto the squash.

The warm spices add enticing aromas and make it seem more like a dessert, but healthier. Right before serving, add some chopped pecans for a nice contrasting crunch.

Recipe Science

Two ways to make squash more flavorful

Cook the halves flesh-side down. Direct contact with the hot baking sheet develops more Maillard browning. I like to wait to season it with salt and pepper until after it’s done roasting. The salt draws out the moisture from the cut flesh and brings it to the surface. The salt causes the squash to steam instead of brown, which we want to avoid.

  • 1 butternut squash, about 1 ½ to 2 pounds
  • 2 tablespoons olive oil, divided
  • kosher salt, for seasoning
  • black pepper, for seasoning
  • 1 tablespoon maple syrup
  • ¼ teaspoon ground cinnamon
  • teaspoon nutmeg
  • 2 tablespoon chopped pecans, optional


  • Set the oven rack to the center position and preheat to 400ºF (204ºC).
  • Wash and thoroughly dry the butternut squash.
  • Place the squash on a sturdy cutting board. Use a sharp chef’s knife to trim the stem and bottom of the squash.
  • Starting at the larger side of the squash, carefully cut in half lengthwise, using small rocking motions.
  • Use a large spoon to remove the seeds. If desired, wash, separate and dry the seeds for roasting later.
  • Line a large baking sheet with foil. Grease the foil with 1 tablespoon of olive oil, use a paper towel to spread evenly.
  • Brush the flesh of the squash with 1 tablespoon of olive oil. Place the squash cut side down and evenly spaced on the baking sheet.
  • Roast until a knife can easily pierce into the flesh, about 30 to 45 minutes depending on the squash’s size.
  • Carefully turn the squash over with tongs and season with salt and pepper. Serve as is or proceed with maple glaze.
  • In a small bowl, combine maple syrup, cinnamon, and nutmeg. Brush evenly on the flesh and roast until the surface is caramelized, about 8 to 10 minutes.
  • Garnish whole roasted butternut squash with chopped pecans.

    Excellent way to cook butternut squash. I followed this recipe and it came out fabulous! Looking forward to trying other recipes from this site.

      The butternut squash sometimes has a sticky, sappy substance that is released when it’s cut, and if you let it dry on your hands it can harden. Washing your hands will easily remove it.

    Thanks!! This is one of the few recipes that include the weight of the squash and the cooking time. Usually, the recipes seem to be for small squash and I am stuck with a 2-3 lb butternut squash without a way to tell if the cooking time applies. My absolute favorite would be a table with cooking times for various squash weigths. Has anyone found that?
    Loving this recipe layout, by the way! Just found it with all the detailed photos and descriptions. Super helpful!!

    • Jessica Gavin says

      Great suggestion! For the timing based on the size, I just use a knife to test for the doneness, if it pierces easily, it’s ready! I always check every 5 to 10 minutes after the initial time recommendation for larger squash.

    I’m making this squash tonight. I’m assuming you roast it UNCOVERED? The syrup mixture sounds amazing! I’ll update results later
