Preheat oven to 400° F. Peel and cube butternut squash. (Disclaimer: I am not responsible for any personal injuries or anxiety attacks.)
Place butternut squash cubes onto a large, rimmed sheet tray.
In a small bowl, mix together olive oil, syrup, cinnamon, cayenne and salt. Pour olive oil mixture over cubed squash and toss with your hands to coat. Spread out squash so that it is in an even layer.
Bake for 15-30 minutes, stirring halfway through. Cooking time will depend on how crowded your squash is and how big your cubes are. You want the squash to be fork tender (stick a fork in and it comes right back out), but not mushy.
Enjoy as a side dish or on a leafy green salad.
The size of the squash will determine how many servings there are.
