11 Tips For Reheating Mashed Potatoes In a Crock Pot

Reheating mashed potatoes in a crock pot is an option I find quite convenient, especially when dealing with large quantities. It frees up your stovetop and oven, which can be a real advantage during big meals or holidays. Plus, the gentle, even reheating helps maintain the original flavor and texture of the mashed potatoes.

Here are some of my top tips for reheating mashed potatoes in a slow cooker to make it just as enjoyable as when they were freshly made. Let’s dive in!

1. Thaw Frozen Potatoes

If your mashed potatoes are frozen, it’s best to thaw them in the fridge before reheating. This makes it easier to achieve a uniform texture and also speeds up the reheating process. Cold, frozen potatoes could take much longer to reheat and may not do so evenly.

2. Grease the Crock Pot

Apply a layer of butter or oil to the bottom of the crock pot before adding your potatoes. This simple step helps prevent sticking and could also contribute a bit of extra flavor to your potatoes. You can use cooking spray for a quick and even coat.

Top Tip: Consider using a slow cooker liner for a quick and easy cleanup. This is especially helpful if you’re using the crock pot for multiple dishes during a big meal. A liner will save you time and effort, allowing you to focus more on enjoying your meal than on post-dinner cleanup.

3. Use Low Heat

The ideal setting for reheating mashed potatoes in a crock pot is the low heat setting. Using high heat can cause the potatoes to dry out or become gummy. Depending on how much mashed potatoes you’re reheating, expect it to take between 2-4 hours on low heat.

4. Stir Occasionally

Stirring your mashed potatoes every 30 minutes to an hour ensures they reheat evenly. This also prevents any uneven textures or temperatures in your potatoes. Just a quick stir will do—no need to spend too much time on it.

5. Add Liquid

If you find your mashed potatoes are getting a bit dry, adding some liquid can help restore their creamy consistency. Whether it’s milk, water, cream, or broth, add it in small increments and stir.

It’s a good idea to use a warm liquid as the cold liquid can slow down the reheating process, while hot liquid might cook the potatoes unevenly.

6. Adjust Seasoning

Flavors can dull during refrigeration or freezing. As your potatoes start to warm up, taste them and adjust the seasoning accordingly. A pinch of salt, a dash of pepper, or other favorite spices can revitalize the taste.

7. Check Temperature

Food safety is a priority when reheating food. Ensure your mashed potatoes reach an internal temperature of at least 165°F (74°C). A proper mixing and food thermometer is the most accurate way to confirm that the potatoes are fully reheated and safe to eat.

8. Add Cheese

Want to amp up the flavor? Grated cheese like cheddar or Parmesan can be a great addition. Sprinkle it over the top about 30 minutes before you’re finished reheating. This gives the cheese enough time to melt but prevents it from getting too gooey or sticky.

9. Garnish with Herbs

A bit of freshly chopped parsley, chives, or other herbs can add a splash of color and flavor. Add them during the last few minutes of reheating to ensure they keep their color and freshness.

10. Avoid Overheating

Too much heat for too long can turn your mashed potatoes into a gummy mess. It’s important to check the texture from time to time. Once the potatoes have reached your desired consistency and temperature, turn off the crock pot.

11. Serve

Once your mashed potatoes have been successfully reheated to a safe temperature and adjusted to your taste preferences, they are ready to serve.

Top Tip: Once your mashed potatoes have reached the desired temperature and consistency, you can keep them warm in the crock pot without further cooking them. Simply switch the crock pot setting to “Keep Warm” if it has one. This is a great way to ensure that your mashed potatoes stay warm and delicious while you wait to serve them, especially during big meals where timing can be tricky.

Why Do I Like Reheating Mashed Potatoes in a Crock Pot?

For many, the idea of reheating mashed potatoes in a crockpot might seem unnecessarily time-consuming, but I can assure you, that there are some undeniable benefits to this method.

  1. Gentle Heating: I really appreciate how crockpots gently heat the mashed potatoes. It’s a big plus because it reduces the risk of overcooking or burning, unlike the more intense heat you might get from an oven or stovetop. This slow and steady approach means I don’t have to hover over the pot, constantly worrying about scorching.
  2. Keeps Moisture Locked In: One thing I’ve noticed is that the crockpot does an amazing job at keeping the mashed potatoes moist. The sealed environment prevents moisture from escaping, which can be a problem in an oven where the heat tends to dry things out. This means the potatoes stay creamy and delicious.
  3. Great for Large Batches: When I have a big batch of mashed potatoes, the crockpot is my go-to. It’s so much easier than trying to reheat them on the stove, where I’d need to stir them often to avoid sticking. Plus, it can handle a larger quantity than what I could fit into a single stovetop pot.
  4. Hands-Off Convenience: I love that I can just set the crockpot and not worry about it until it’s time to eat. This is super helpful when I’m juggling other tasks in the kitchen. It frees up my time and attention so I can focus on preparing other parts of the meal.
  5. Ideal for Extended Warmth: Lastly, the crockpot is perfect for keeping the mashed potatoes warm over a long period. This is something I struggle with on the stovetop, where keeping a consistent, non-drying heat can be tricky. The crockpot maintains that ideal warm temperature without drying out or overcooking the potatoes.

In Summary

So, there you have it. I’ve shared my go-to strategies for reheating mashed potatoes in a crock pot. Not only does it free up stovetop space, but it also gives you a hands-off approach. You can literally set it and forget it until it’s time to eat. Trust me, it makes life a bit easier. And remember, it’s all about prepping right, using those handy liners for a quick cleanup, and keeping those spuds warm for serving.
