Turn acorn squash upside down (skin side up) onto an aluminum foil-lined baking sheet. Bake until squash begins to soften, approximately 30 to 45 minutes.
Remove squash from the oven and turn over so that the flesh is facing up. Place 1 tablespoon butter and 2 tablespoons brown sugar into each squash half.
Bake another 30 minutes.
To serve, you can scoop out the insides and place in a dish, or just eat it right out of the squash (which is what we did!)
