The best way to heat up mashed potatoes is to gently warm them on the stove with a splash of milk, stirring until creamy and heated through.
Nothing’s worse than dry, lumpy mashed potatoes after reheating. Whether it’s Thanksgiving leftovers or a quick weeknight side, cold spuds lose their creamy texture fast. The right reheating method can restore fluffiness without sacrificing flavor. In this guide, we’ll cover the top techniques—from microwave hacks to stovetop tricks—plus pro tips for adding moisture.

Key Takeaways
- Microwave is fastest but requires frequent stirring
- Stovetop delivers even heat with better texture control
- Always add butter, cream, or broth to prevent dryness
- Oven baking works best for large batches
1. Microwave: Quick & Easy
Reheat in microwave with butter or cream, stirring every 30 secs. Ideal for small portions, this method takes under 5 minutes:
- Transfer potatoes to a microwave-safe bowl
- Mix in 1 tbsp butter or cream per cup
- Cover with a damp paper towel to trap steam
- Heat at 50% power in 30-second bursts, stirring between cycles
Avoid rubbery textures by not overheating. For extra creaminess, whisk in warm milk after reheating (USDA recommends 165°F internal temp).
2. Stovetop: Best for Creaminess
Double-boiler method prevents scorching:
- Place potatoes in a heatproof bowl over simmering water
- Add 2 tbsp liquid (milk, broth, or cream) per 2 cups
- Stir gently with a silicone spatula until heated through
Perfect for larger quantities, this technique mimics restaurant-quality results. Pro tip: Infuse flavor by warming liquids with garlic or herbs first.
3. Oven: Ideal for Big Batches
For holiday leftovers or meal prep:
- Preheat oven to 350°F
- Spread potatoes in a baking dish with ½” chicken broth layer
- Cover with foil and bake 20-30 minutes
- Stir halfway, adding more liquid if needed
Creates evenly heated potatoes without constant supervision. Casserole-style dishes like Food Network’s au gratin work well here.
4. Slow Cooker: Keep Warm for Hours
Party-friendly solution:
- Grease crockpot with butter
- Mix in ¼ cup sour cream per 3 cups potatoes
- Cook on LOW 2-3 hours, stirring occasionally
Prevents crust formation better than other methods. Add cheese during last 30 minutes for loaded mashed potatoes.
Reheating Methods Comparison
| Method | Time | Best For | Texture |
|---|---|---|---|
| Microwave | 2-5 mins | Single servings | Slightly gummy |
| Stovetop | 10-15 mins | Medium batches | Ultra-creamy |
| Oven | 20-30 mins | Large quantities | Fluffy |
| Slow Cooker | 2+ hours | Keep-warm needs | Rich |
5. Pro Tips for Perfect Reheated Potatoes
- Storage matters: Use airtight containers to prevent fridge absorption
- Temperature check: Always verify 165°F with a food thermometer
- Revive gluey potatoes: Fold in whipped cream or olive oil
With these methods, your mashed potatoes will taste freshly made every time. Experiment with different liquids (buttermilk, stock) for unique flavors. Now that you’re a reheating pro, those leftovers will shine brighter than the first serving!
