This Reuben Casserole has all the comforting flavors of a classic Reuben sandwich in a warm, easy baked dish that’s perfect for busy weeks or low-energy days. It comes together with simple steps and bakes into a cozy, melty dinner the whole family can enjoy.
This casserole reheats well and makes an easy leftover lunch the next day.
You can assemble it earlier in the day, cover and chill, then bake when you’re ready for dinner.
For a lighter version, use half Swiss and half mozzarella or swap in turkey pastrami.
