Ingredient Notes

Ingredients used to make cinnamon roasted butternut squash on a white textured background.
  • Butternut Squash: Be sure to properly prepare the butternut squash by washing the outside, peeling the skin, and removing the seeds and strings. Then chop butternut squash into equal pieces to ensure even roasting. You’re also welcome to use store-bought pre-cut butternut squash instead of a whole squash. 
  • Cinnamon: If you want a more potent cinnamon flavor, you can add more. 
  • Brown Sugar: The brown sugar will bring out the natural sweetness of the butternut squash. If you’d rather, you can omit the sugar then drizzle with pure maple syrup when finished. 
  • Butter and Oil: Using a combination of butter and oil will provide the perfect flavor for this roasted butternut squash recipe. 

Step-by-Step Instructions

  1. Prepare the squash. Wash, peel, and clean out the inside of the squash. Cut into small cubes (about 1/2 inch to 1-inch cubes) and place in the center of a baking sheet. Drizzle with 2 tsp olive oil and 1 tablespoon melted butter. Toss to coat.

  1. Sprinkle with brown sugar and cinnamon. Add 2 tablespoons brown sugar, 1/2 teaspoon ground cinnamon and 1 tsp kosher salt. Toss to coat and spread in an even layer. 
  2. Bake. Bake the cinnamon butternut squash at 425ºF for 25-35 minutes (checking the squash at 25 minutes, and cooking for longer if needed). Remove when the butternut squash is fork tender. Enjoy warm!

Recipe Tips

Do your best to keep the diced pieces uniform in size. Keeping them uniform allows for a more even bake.

If your squash was cubed into larger chunks, you’ll want to roast the squash for longer. Keep an eye on it. Remove the squash from the oven when you can easily insert a fork into the squash. 

Add more or less brown sugar depending on your preference. 

Keep the squash pieces in a single layer for best roasting. 

Use a piece of parchment paper on your baking sheet for easy clean up. 

Make Ahead, Storing, and Freezing

Make-Ahead: You can prepare the cubed butternut squash and store it in an airtight container in the refrigerator for up to 24 hours before roasting. When ready, follow the roasting instructions.

Storing: Leftover Cinnamon Roasted Butternut Squash can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat in the oven or microwave for a quick and delicious side dish.

Freezing: While it’s best enjoyed fresh, you can freeze roasted butternut squash in an airtight container for up to 2-3 months. Thaw and reheat in the oven to restore the texture and flavor.
