Maybe you have time, or you’re feeding a crowd. The oven is mythic for large batches, but it’s a longer game. Preheat to 350°F (175°C).
The Best Way To Reheat Frozen Mashed Potatoes And Bring Them Back To Life
Spray a baking dish with oil. Spread the frozen potato chunks in a single layer. Dot the top with lots of butter—like, more than you think you need. Cover tightly with foil.
Bake for 30 minutes. Then, uncover, stir in a splash of milk, and bake another 10-15 minutes until the top gets slightly golden. The contrast of a crispy top and creamy center is chef’s kiss.
Downside? It’s slower. But the smell that fills your kitchen? Pure comfort. (Plus, you can hide in the kitchen while your family smells the butter.)
