Bacon Cheeseburger Grilled Cheese Casserole

This casserole can be made ahead of time. Prepare it up until the point of baking, cover it with foil, and store it in the refrigerator for up to 2 days. When ready to bake, simply remove it from the fridge and bake as directed. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, warm it in the oven at 350°F (175°C) for 15-20 minutes, or until heated through.

Tips

• If you prefer a spicier casserole, you can add a few dashes of hot sauce or jalapeños to the beef mixture.
• For added flavor, try using a mixture of cheeses, such as adding pepper jack or gouda to the mozzarella and cheddar for extra depth.
• If you want a crunchier topping, you can sprinkle some additional shredded cheese or even crushed crackers over the top before baking.
