This 'Bubble Up Pizza Casserole' is a comforting and simple dish. It combines seasoned ground beef and onion simmered in spaghetti sauce, layered with quartered flaky biscuits and melted mozzarella cheese. Baked until golden and bubbly, it offers a quick, family-friendly meal with a delightful pizza-inspired twist.
Ensure ground beef is thoroughly browned and excess fat drained before adding other ingredients; this enhances flavor and texture. For a richer sauce, consider a pinch of Italian seasoning or dried oregano during simmering. Arrange the quartered biscuits evenly over the sauce to promote consistent baking and the desired 'bubble up' effect. Avoid over-baking; the goal is golden biscuits and bubbly, melted cheese. A short rest after baking allows the casserole to set, making it easier to serve.
