Cooking the potatoes together with the milk and cream, then adding in roasted garlic cloves for a delicious garlic flavor that isn't overpowering. This method makes for the creamiest and most flavorful mashed potatoes. They're perfect for making ahead of time for easy entertaining!
What's 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!
Make Ahead Roasted Garlic Mashed Potatoes
- 1 head garlic
- extra virgin olive oil
- 4 pounds yukon gold or russet potatoes, peeled and quartered
- 2 cups heavy cream
- 2 cups whole milk
- 8 fresh sage leaves
- 3 sprigs fresh thyme
- 6-8 tablespoons salted butter, at room temperature
- kosher salt and black pepper
- Preheat the oven to 400° F.
- 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.
- Let the garlic cool, then squeeze out the cloves.
- 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.
- 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.
- 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.
- If desired, brown a little butter with sage or thyme and swirl into the potatoes before serving. Serve warm and creamy.
To Make Ahead:
- 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.
