The magic of buttermilk
I read an article years ago about a famous restaurant in San Francisco called The Zuni Café. There was a quote from the chef, Judy Rodgers, that I found fascinating. She said that whenever buttermilk mashed potatoes were on the menu, whatever they were paired with, was the first thing that sold out. I decided to try buttermilk in my mashed potatoes and I’ve never looked back. Buttermilk has always been quite magical to me in both baking and cooking, and it definitely enhances the flavor and creaminess of mashed potatoes.
The easiest mashed potatoes you’ll ever make!
Although mashed potatoes aren’t difficult to make in the traditional way, they can be a little tricky to get timed just right. Especially if you’re trying to coordinate other components of the meal. There’s also the problem of keeping the potatoes warm until it’s time to serve without scorching on the bottom or having them dry out. With Slow Cooker Buttermilk Mashed Potatoes, these problems are totally eliminated! Yay!
Indeed, the slow cooker is quite amazing when it comes to mashed potatoes. How does it work? Just peel and cut up your potatoes then add them to the slow cooker with chicken broth and water. Cover and cook until they’re nice and tender, drain well, then add the good stuff; buttermilk, milk, butter and salt.
Mash the potatoes right in the pot and keep them warm till you’re ready to serve – even if it’s several hours! Whenever you’re ready, your potatoes will be too!
Café Tips for making these Slow Cooker Buttermilk Mashed Potatoes
- Every slow cooker is a little different as far as cooking times, so check the potatoes often during the last hour. You may find you need more or less time than specified in the recipe.
- For creamy, lump-free potatoes, you want to let them get nice and soft, almost to the point of falling apart.
- Make these mashed potatoes up to 2 days in advance, then cool and refrigerate. Place the cold potatoes in the slow cooker on low, 1-2 hours before serving. Once the potatoes are warmed through, check the consistency. Add more milk, a few tablespoons at a time and stir, until desired consistency is reached. Keep warm (on low setting) until ready to serve.
- For garlic mashed potatoes, add 2 cloves of garlic with the raw potatoes and broth. They’ll be super soft and will blend right in with the potatoes when mashing.
- For an attractive presentation, place potatoes in a serving bowl and swirl the top with the back of a serving spoon. Dot with butter and sprinkle lightly with sweet paprika.
- I love my KitchenAid Multi Cooker. It’s a slow cooker, but also has settings for keep warm, simmer, boil, sauté and sear. That means you can do just about anything in it, including browning meats and poultry to keep them juicy before slow cooking. With most slow cookers you have to do that in a separate pan which, to me, defeats the easiness of slow cooking. With the Multicooker, you can do it all in this one beautiful pot. Have any cooks on your holiday gift list? This would be a one of those wonderful gifts that keeps on giving, all year long! Who knows? You might even be one of the recipients of something delicious, like this Slow Cooker Pasta e Fagioli Soup!
