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 Yukon gold 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. You will definitely want these along with your turkey and gravy!

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!

Ingredients

Instructions

  • 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.

  1. I want to try the slow cooker way but it says prep until step 6 before putting in slow cooker. Seems like I’m cooking twice. Can you confirm directions for slow cooker? Thx!

    1. Hi there! Yes, prepare until Step 6 for the slow cooker 🙂 The will be nice and creamy and delicious! xTieghan

  2. We always use an electric hand mixer to ‘mash’ our potatoes and don’t own a ricer or masher. Do you think that would work with this recipe? I’d hate to have them end up gluey and grey. Thank you.

  3. how would I cut down this recipe for 2, not 8 servings ??
    would like to try this, but it’s just me and hubby.
    thanks!

      1. When reheating the next day, is the 1/2 cup cream and 2 tablespoons butter in addition to what was already added in step 6 the previous day?

    1. Hi there! If you’re cooking on the stove top I would keep a close eye on it, but I don’t usually have problems when I make them in an Instant Pot! 🙂 xTieghan

  4. Genius!!! While everyone has their favorite mashed potatoes, your method for reheating will be the hint that carries on for generations. I will be trying your recipe for the potatoes. I assume using milk to cook provides a richer mashed potatoe.

  5. Can these be refrigerated then placed in the slow cooker and or the stove top to warm? It only states refrigeration in the oven method, these sound fabulous!

  6. Could these be made using the IP method in the Cheesy Garlic Herb Mashed Potatoes recipe? And…should I have any concerns about it being kept on warm for 5-6 hours instead of four? Just wondering if doing so would overlook something critical food safety-wise.

  7. For dairy free, is it possible to sub coconut milk for both the cream and whole milk? Or would it make the potatoes too watery?

  8. 5 stars
    I’m asking a “DUH” question here. Any reason the dish can’t be frozen and then brought to room temp before reheating? I am going to make this dish but anything I can do the week ahead would really help. Thanks as always “T”! ~Bec

  9. Do you know how many cups of cut potatoes you are using? Google says 1# is 2.25 cups. Does 10 cups sound correct?
