Ingredients for Garlic Mashed Potatoes

  • Potatoes – There are many contenders for the best potatoes for mashed potatoes. Red potatoes and fingerlings will work great if you’re doing this recipe in a more “smashed potato” style. Russets are another solid pick, but you’ll need to be careful about overmixing your potatoes. Yukon Gold potatoes are also a great pick- especially if you’re aiming for a creamy, fluffy end product.
  • Butter
  • Milk – Experiment with half-and-half or heavy cream and see if it helps make a creamier dish!
  • Parmesan
  • Sour Cream
  • Minced Garlic
  • Thyme, Basil, Oregano – Or try using some of our homemade Italian Seasoning!
  • Onion Powder
  • Salt & Pepper

How to prepare our Slow Cooker Mashed Potatoes

After roughly chopping your potatoes of choice, prep your slow cooker by giving it a quick coating of Crisco shortening or cooking spray. Drop your potatoes, butter, minced garlic, and salt & pepper into the slow cooker along with some water.

Now we’re going to cover and let our potatoes cook for a bit. Either set your cooker to low and let go for around 8 hours or set to high and let cook for around 4. When done, use either a hand masher to smash or an electric mixer to beat your potatoes close to your desired consistency.

We want to stop close to our consistency because we want to add in our other ingredients. Drop-in your sour cream, parm, milk or cream, and the remaining spices.

Use an electric mixer to whisk these into your potatoes. Again, if you’re using Russets, be careful not to overmix your potatoes here- it will lead to a really unpleasant, paste-like texture.

If you have any concerns about the texture at this point, feel free to mix a bit more milk or cream into the potatoes.

At this point, we can add any toppings you might want to have. Maybe a big extra dollop of butter or a quick sprinkling of parsley flakes for a bit of extra color?
