Make-Ahead and Freezer Tips for Easy Shepherd’s Pie Casserole

Make-ahead (fridge):
Assemble the casserole completely (meat layer + mashed potatoes + cheese), then cover the dish tightly with plastic wrap and foil. Store in the refrigerator for up to 24 hours. When ready to bake, let it sit at room temperature for 15–20 minutes, then bake as directed. You may need to add an extra 5–10 minutes of baking time if it’s very cold.Freezer-friendly option:
