A fun, all-in-one casserole that layers seasoned ground beef, tangy Big Mac sauce, and crispy tater tots, then bakes until bubbly and golden. The melty cheddar and sharp pickles mimic the iconic burger in every scoop, while the tots stay crunchy on top.
Storage: Refrigerate leftover casserole in an airtight container for up to 3 days. Freezing: Assemble the casserole (without lettuce and sesame seeds) and freeze unbaked for up to 2 months. Thaw overnight in the fridge before baking as directed. Reheating: Reheat individual portions in a 350°F (177°C) oven or toaster oven for 10-12 minutes, or in the microwave at 70% power for 2-3 minutes until hot. For best crispness, reheat in the oven.
