Smoky Bacon Cheddar Grilled Cheese Bake is a cozy, sheet-pan grilled cheese upgrade made with sourdough, crispy bacon, sharp cheddar, and a smoky seasoned mayo that bakes up golden and bubbly in the oven. It’s perfect for feeding a small crowd with minimal hands-on time—no flipping sandwiches at the stove one by one.
Why you’ll love this recipe
This bake uses the same logic as popular sheet-pan grilled cheese methods: assemble everything on a tray, then let the oven melt the cheese and crisp the bread evenly. Sourdough is sturdy, flavorful, and holds up beautifully to generous layers of cheese and bacon, much like other bacon grilled cheese recipes that call for hearty bread.
Seasoned mayonnaise on the outside of the bread helps it brown deeply and evenly, a technique many grilled cheese guides recommend because mayo browns more reliably than butter alone. Garlic powder, onion powder, and smoked paprika build a smoky, savory profile without needing special smoked cheese, similar to smoked cheddar or bacon grilled cheese versions.
