Sometimes the best dinners are the ones that feel a little nostalgic but taste even better than you remember. This Sloppy Joe Casserole takes that saucy, tangy beef we all know and love, tops it with a soft, cheesy biscuit layer, and finishes with a brush of garlic butter. It’s the kind of cozy, weeknight dinner that has everyone wandering into the kitchen asking, “When’s it ready?”
