Baking dish: If you don’t have an oven-safe pot, make the casserole through Step 5, then transfer to a 9×13-inch baking dish. Proceed with Step 6.
Make ahead: Assemble the whole casserole but do not bake. Let cool, then cover and refrigerate for up to 1 day. Let the casserole sit out at room temperature while the oven heats. Bake uncovered according to directions, adding 10 to 15 minutes to the bake time.
Storage: Leftovers can be refrigerated in an airtight container for up to 4 days.
