Cheesy Thyme Mashed Potatoes

A classic side-dish for Thanksgiving, enjoy these mashed potatoes with your choice of cheese on top. (Recipe Credit: Adrianna Adarme of Fresh Tastes)


Yield: Serves 6 to 8 (as a side)


  • 2 1/2 pounds russet potatoes (about 4 potatoes)
  • 4 tablespoons unsalted butter
  • 3 sprigs of thyme, plus more as garnish
  • 1 1/2 cups heavy cream
  • 1 3/4 teaspoon salt, plus more to taste
  • Freshly ground pepper
  • 1 cup finely shredded cheddar cheese/fontina or another melty cheese


  1. Peel all the potatoes and dice them into 1-inch cubes. This doesn’t have to be perfect but try your best to get them to be uniform in size.
  2. If you own a steam-basket, great—use it! I don’t own one so I made a make-shift steam basket by filling up a 3-quart Dutch oven/pot with a few inches of water. I then nestled a sieve on top and added the potatoes to it and covered the potatoes with foil.
  3. Place your steam basket/make-shift thing over medium-high heat. Steam the potatoes for about 30 to 35 minutes, stirring them about half way through. Give them a taste and make sure they’re VERY soft. Remove them from the steam basket and run them through the potato ricer, in batches, into the bowl or a stand-up mixer (or just a regular ol’ medium bowl).
  4. Repeat this step until you’ve worked your way through all of the potatoes.
  5. In a small saucepan, add the butter and thyme. Warm over medium-low heat until the butter has melted. Allow to steep for about 5 minutes. Next, add the heavy cream and heat until just warm. Discard the thyme leaves. Pour that into the stand-up mixer bowl, along with the salt and pepper and beat, with the paddle attachment, for about 1 minute. Scrap down the sides, if you need to. Give it a taste and adjust the salt to your liking. Add the cheese and stir until melted.
  6. Serve immediately or store in the fridge to reheat later.
