How to Reheat Mashed Potatoes
Leftover mashed potatoes.
The Short Answer
The best way to reheat mashed potatoes is on the stovetop with cream. Stovetop over low heat with a splash of cream or milk, stirring frequently. The only method that truly restores creamy texture.
Reheating Methods
🔥 Oven
Temperature: 350°F
Time: 20–30 minutes
Dot with butter, cover with foil. Stir once halfway through.
📡 Microwave
Time: 2–4 minutes
Add cream, cover. Heat in 1-minute intervals, stirring between each.
🍳 Stovetop
Time: 5–10 minutes
Add 2 tablespoons cream or milk per cup. Stir frequently over low heat until creamy and hot.
Do not reheat without adding liquid. Refrigerated mashed potatoes lose moisture and become stiff and gluey.
Add a generous pat of butter and a splash of cream while reheating on the stove. Stir gently over low heat. They come back to life beautifully.
Frequently Asked Questions
Overworking the starch during reheating and not adding enough liquid. Use a gentle folding motion rather than aggressive stirring, and add cream or butter.
The Bottom Line
The best way to reheat mashed potatoes is on the stovetop with cream. The key to great reheated food is low-and-slow heat, moisture retention, and patience. Rushing with high heat dries food out and creates uneven hot and cold spots. When in doubt, go lower and slower. Make sure leftovers reach an internal temperature of 165°F before serving.
