Perfect Creamy Garlic Mashed Potatoes – Kosher Recipe

Jump to Recipe Print Recipe

I’ve been making mashed potatoes for years, but it took me way too long to figure out the secret to truly creamy ones that don’t turn gluey or lumpy. The trick isn’t just in the type of potato you choose, though that matters a lot. It’s about understanding how starch works and treating your potatoes gently throughout the whole process.

Yukon Gold potatoes are my go-to for mashed potatoes because they hit that sweet spot between starchy russets and waxy red potatoes. They’ve got enough starch to create a fluffy texture but not so much that you’ll end up with wallpaper paste if you overmix them. I always start them in cold, salted water rather than dropping them into boiling water. This ensures they cook evenly from the outside in.

Why Yukon Gold Potatoes Work Best

The garlic component here isn’t just minced raw garlic thrown in at the end. I roast whole cloves until they’re golden and sweet, then mash them right into the potatoes. This gives you that deep, mellow garlic flavor without any harsh bite. For the dairy component, I use a combination of butter and either whole milk or heavy cream, depending on whether I’m serving this with meat or dairy dishes. The key is heating your liquid before adding it to prevent the potatoes from cooling down and becoming dense.

The Roasted Garlic Secret

These mashed potatoes work beautifully alongside roasted chicken, brisket, or even as part of a dairy meal with roasted vegetables. I make them for Shabbat dinners regularly, and they reheat well if you add a splash of warm milk and fluff them with a fork. The texture stays creamy for days in the fridge, which makes them perfect for meal prep or holiday cooking when you’ve got a million things on your plate.

Ingredients Method Notes

Ingredients
  

  • 3 pounds Yukon Gold potatoes peeled and cut into 2-inch chunks
  • 1 head garlic top cut off to expose cloves
  • 2 tablespoons olive oil for roasting garlic
  • 1/2 cup unsalted butter room temperature
  • 1/2 cup whole milk warmed, or heavy cream if serving with dairy meal
  • 1 1/2 teaspoons kosher salt plus more for pasta water
  • 1/2 teaspoon black pepper freshly ground
  • 2 tablespoons fresh chives chopped, for garnish

Method
 

  1. Preheat oven to 400°F. Drizzle the cut garlic head with olive oil, wrap tightly in foil, and roast for 30-35 minutes until cloves are golden and soft.
  2. Meanwhile, place the chunked potatoes in a large pot and cover with cold water by 2 inches. Add 1 tablespoon kosher salt to the water.
  3. Bring to a boil over high heat, then reduce to medium-high and cook for 15-20 minutes until potatoes are fork-tender and break apart easily.
  4. Warm the milk in a small saucepan over low heat or microwave for 30 seconds. Don't let it boil.
  5. Drain the potatoes thoroughly in a colander and let them sit for 2-3 minutes to release excess moisture.
  6. Return potatoes to the pot and mash with a potato masher or pass through a ricer for ultra-smooth texture.
  7. Squeeze the roasted garlic cloves out of their skins and mash them with a fork. Mix the mashed garlic into the potatoes.
  8. Add the butter and mix until melted, then gradually add the warm milk while stirring until you reach desired consistency.
  9. Season with 1 1/2 teaspoons kosher salt and black pepper. Taste and adjust seasoning as needed.
  10. Transfer to a serving bowl, create a small well in the center, and garnish with fresh chives before serving.

Notes

For make-ahead: These reheat beautifully. Add a splash of warm milk and fluff with a fork before reheating in a 350°F oven for 20 minutes. If serving with a meat meal, substitute the milk with additional butter or vegetable broth for a pareve version. Store leftovers in refrigerator for up to 4 days.
