French Onion Ground Beef and Rice Casserole is a cozy, family-style dinner that layers savory ground beef, tender rice, and the rich flavor of French onion soup into one creamy, cheesy bake. It takes everything people love about French onion soup—the deep caramelized onion taste and comforting warmth—and turns it into a hearty, satisfying casserole that feeds a crowd with minimal fuss.
This recipe is built for real-life weeknights. You brown a pound of ground beef with onion, stir it together with cooked rice, a can of French onion soup, sour cream, and cheddar, then bake until hot and bubbly. The result is a classic “dump-and-bake” style casserole that still feels special enough for Sunday dinner, chilly evenings, or potluck tables.
