No matter what in-season veggie you happen to have on hand, chances are that after just a quick roast in the oven, it will have turned oh-so-sweet — and seasonal squash is no exception. Butternut, acorn, spaghetti and delicata squashes are all overflowing at farmers market stands and in supermarket aisles alike this time of year, and while you can indeed simply roast them and enjoy them as is, in all their tender glory, dressing them up a bit with bold, fresh flavors will transform them even more.

In his recipe for Roasted Acorn Squash with Mushrooms, Peppers and Goat Cheese, Guy Fieri precooks the squash for a few minutes in the oven before filling it with a hearty, savory stuffing that's easy to make yet endlessly impressive. He opts for a mixture of cremini mushrooms, fresh cabbage and colorful bell peppers for heft and texture, plus a few cloves of garlic for over-the-top taste. Follow Guy's lead and top the filling mixture with goat cheese and roasted acorn seeds before baking; the tangy crumbles of cheese deliver the richness you crave, while the acorn seeds promise a welcome salty, crunchy bite.
