To create the perfect Sheet Pan Southern Meatloaf, one must embrace the comforting essence of traditional Southern cooking while enjoying the convenience of modern culinary techniques. Start by combining finely minced beef with a medley of sautéed onions, bell peppers, and garlic, which infuse the meat with a robust flavour. Add breadcrumbs soaked in milk and a hint of Worcestershire sauce for moisture and depth.

Once you’ve shaped the mixture into a generous loaf on a lined baking sheet, it's time to elevate it with a scrumptious glaze. A mixture of ketchup, brown sugar, and a dash of mustard provides a tangy sweetness that caramelises beautifully in the oven.

Arrange some seasonal vegetables around the meatloaf to roast simultaneously, soaking up those rich, meaty juices. This one-pan marvel not only offers a hearty, family-style meal but also makes for easy clean-up, leaving you more time to relish this Southern classic. Pair it with creamy mashed potatoes and a side of collard greens for a truly comforting feast.
