Slow Cooker Mashed Potatoes

I don’t know if you know this, but I avoid mashed potatoes like the plague. Don’t get me wrong, I love to eat them, but I just hate to make them. Part of that reason is that I keep forgetting to buy a potato masher. But potato masher aside, I just hate the peeling, chopping, boiling, draining, mashing, the whole bit. They just feel like a lot of work. But then I discovered Slow Cooker Mashed Potatoes and they were just the short cut I needed to get over my mashed potato aversion!

Why Make Mashed Potatoes in a Slow Cooker?

Using the slow cooker cuts out the “babysitting the boiling pot” step in the process of making mashed potatoes, which can really free you up to concentrate on the rest of your meal. It also eliminates boil overs, draining the potatoes, constantly checking them with a fork to see if they’re tender, using multiple pots and dishes, and gives you another free burner on your stove top. With slow cooker mashed potatoes, you just add everything to the pot and press a button and go.

How Do You Flavor Mashed Potatoes?

I flavored my mashed potatoes with garlic, pepper, butter, milk, and cream cheese, but you can use your tried and true favorite mashed potato add-ins with this recipe. The cooking process will stay the same: 3 lbs. potatoes and about 1.5 cups of broth. Then after they’re cooked, add in whatever you’d like!

What Kind of Potatoes are Best for Mashed Potatoes?

Russet potatoes are my top choice for mashed potatoes because they have a light, fluffy flesh. You can use red potatoes, but they tend to create a more dense mashed potato.

Can I Make Them Vegetarian?

Absolutely. You can swap the chicken broth listed in the recipe below for vegetable broth. Just be aware that vegetable broth is usually a much darker color, so your finished mashed potatoes will likely look a little more brown.

Use a hand mixer to briefly whip the potatoes until smooth. Be careful not to whip and whip the potatoes for long periods because that can cause the potato starches to become gummy.
