So, cut the ends off of and peel a medium-sized butternut squash. A veggie peeler is super easy! Spoon the seeds out, and dice into about 1" - 1 1/2" cubes.
Line a 9 x13 pan with aluminum foil (easy clean-up!) and spray with cooking spray. spread the squash cubes out on the pan.
Mix 3 tablespoons unsalted melted butter, 1/8 cup brown sugar, 3/4 teaspoon kosher salt, and 1/2 teaspoon pepper.
Withe clean hands, mix together the butter mixture onto the squash. Spread the squash out on a single layer on the pan again.
Bake at 400* for about 45-50 minutes, or until squash is fork tender and the sauce begins to caramelize.
Enjoy! {we ate it with green beans and brown rice!}
