Preheat the oven to 375° F. Cut the squash in half and remove the seeds.

Place the squash into a 9×13 baking pan, and half stick of butter and half cup of the brown sugar to each half of the squash.

Place the squash in the preheated oven and baked for 45-60 minutes, until squash is tender.

Remove the squash from the oven, pour out the liquid into a small bowl.

Scoop out the flesh from the skin into a medium size bowl.

Mash the squash with a fork, adding a small amount of the liquid back in just to keep it moist.

Transfer to a baking dish and top with more brown sugar.

Bake the squash for 15-20 minutes until the brown sugar topping is crispy.

Remove from the oven and serve your Squash Casserole with your favorite main dish such as Country Style Pork Ribs, Easy Traditional Meatloaf, or Brown Sugar Glazed Pork Chops.
