The secret to these potatoes?

Two things… first, the roasted garlic. Roasting the garlic adds just the right amount of garlic flavor that’s delicious but not over powering.

Second, cook the potatoes together with the milk and herbs. This means no boiling the potatoes, no extra steps, nothing fancy. It turns out that creating almost perfect mashed potatoes is actually really easy.

The steps – roast the garlic

Start with the garlic since it takes time to roast in the oven. If you’ve never done it before it really adds a layer of deliciousness to your recipes.

Simply slice the top portion of the garlic head off to reveal the cloves. Then place the garlic on a small piece of foil, drizzle with olive oil, and wrap the garlic up. Roast for about forty minutes, until the garlic is deeply golden and soft.

Then simply squeeze the cloves out of the garlic skin.

Meanwhile, make the potatoes

Combine the potatoes with the milk and cream in a large pot on the stove. Add the herbs, then cook until the potatoes are tender. This will take about twenty-five minutes or so. Once the potatoes are cooked, drain them, BUT, be sure to save the cream – you’ll need it!

Now, the potato ricer…it’s key to making ultra-smooth mashed potatoes. Do you have to have a potato ricer? No, a good ole masher works too. But if you want the smoothest mashed potatoes, a ricer works really well.

Take the mashed potatoes and those roasted garlic cloves and put them right back into the pot. Then add back the cream and also add some butter. Cook until the butter is melted…and that’s it…the most perfectly flavored creamy mashed potatoes!

Honest these are the BEST – classic, but with amazing flavor and texture.

The added bonus is just how easy these are to make…and that you can make them ahead of time. Steps for warming in the oven, slow cooker, or on the stove are listed in the directions!

  • 1. Preheat the oven to 400° F.
    2. Slice off the top portion of the garlic head to expose some of the cloves. Place the garlic on a piece of foil. Drizzle with olive oil, wrap it up, and bake for 40-55 minutes, until deeply golden and very soft.
    3. Let the garlic cool, then squeeze out the cloves.
    4. Meanwhile, In a large dutch oven, combine the potatoes, heavy cream, milk, sage, and thyme. Bring to a gentle boil over medium heat and cook 20-25 minutes, until the potatoes are fork-tender.
    5. Drain the potatoes, reserving all of the cream. Discard the thyme and sage. Press the potatoes and roasted garlic cloves through a potato ricer. Then add them back to the warm pot. Alternately, you can add the potatoes back to the pot and mash with a potato masher.
    6. Over low heat, add 1 1/2 cups of the reserved cream and the butter. Continue to add more of the cream until your desired consistency is reached. Season the potatoes with salt and pepper.
    7. If desired, brown a little butter with sage or thyme and swirl into the potatoes before serving. Serve warm and creamy.

  • In the Oven: Prepare the mashed potatoes as directed through step 6. Spoon the potatoes into a large baking dish. Cover and refrigerate for up to 3 days. To reheat in the oven, preheat the oven to 325° F. Pour 1/2 cup milk or cream over the potatoes and add 2 tablespoons butter, do not stir.

    Awful. Recipe doesn’t call for nearly enough liquid. We followed the recipe precisely and they were burnt to a crisp. Stick with a more traditional recipe if you don’t want your thanksgiving ruined

    1. Hey Austin,
      So sorry to hear this, was there anything you adjusted in the recipe? What kind of potatoes did you use? There should have been plenty of liquid. Let me know how I can help! xTieghan

  2. Thank you for this AMAZING recipe! I opted to make these for the make-ahead opportunity to alleviate some stress on Thanksgiving. Since Thursday I have made twice more and shared with about 15 people. These are the creamiest, most flavorful, beautiful mashed potatoes ever. Boiling the potatoes in the cream and milk, along with the herbs infused them with such flavor and then adding the roasted garlic was next level. They stay creamy upon reheating and smell amazing all along the way. Your photography, step-by-step detail and serving suggestions are incredible too. I can’t wait to try more of your recipes!

    1. Hi Julie,

    Delicious! I also made the night before and put in the crockpot for easy transport. As suggested, I added some of the left over sage/thyme infused cream and a bit more butter when warming up. The hint of roasted garlic and spices took this crowd favorite to a new level. Thank you!

    1. Hey Colleen,
      Wonderful!! I am thrilled to hear that this recipe was enjoyed, thanks so much for making it! Have a great weekend! xTieghan
