There is nothing quite like a heaping platter of roasted vegetables, and tossing them with cowboy butter makes this dish truly special. The savory butter blend coats every veggie in bold flavor. I love this as a comforting side dish to just about any meal, especially on cooler nights when the kitchen smells rich with garlic and herbs.
I first made this for a backyard barbecue, and it was the first dish gone. Now my friends request it every time I host.

Storage Tips
Allow leftovers to cool fully before transferring to a lidded container Store in the refrigerator for up to four days I find they are just as good reheated on a sheet pan or tossed into a skillet with a splash of water to crisp back up
