Perfect Creamy Garlic Mashed Potatoes – The Ultimate Kosher Side Dish

Jump to Recipe Print Recipe

I’ve been making mashed potatoes for family dinners since I was tall enough to reach the stovetop, but it took years to figure out what separates good from absolutely incredible. The secret isn’t just butter or cream. It’s understanding how different potato varieties behave and knowing exactly when to add your garlic for maximum flavor without any harsh bite.

Russet potatoes are your best friend here. Their high starch content creates that fluffy, light texture we’re after, while waxy potatoes like red or fingerlings will leave you with gluey, disappointing results. I learned this the hard way at a Shabbat dinner where I confidently used whatever potatoes were on sale. The guests were polite, but I knew I’d failed when even my teenage nephew passed on seconds.

Why Russet Potatoes Make the Creamiest Mash

The garlic technique makes all the difference. Raw garlic will overpower everything and leave you with an acrid taste that lingers. Instead, I simmer whole cloves in the milk until they’re tender and sweet, then mash them right into the potatoes. This creates a mellow, nutty garlic flavor that complements rather than competes. Don’t skip the step of heating your milk either. Cold dairy will cool down your hot potatoes and make everything harder to combine smoothly.

The Garlic Game-Changer: Simmered Not Raw

These potatoes work beautifully alongside roasted chicken for Shabbat dinner or beef brisket for holidays. They’re also fantastic with simple grilled fish during the week. I always make extra because they reheat surprisingly well with a splash of warm milk stirred in. Just don’t try to make them too far ahead, they really are best served within an hour of making.

Ingredients Method Notes

Ingredients
  

  • 3 pounds russet potatoes peeled and cut into 1-inch chunks
  • 6 cloves garlic peeled and left whole
  • 3/4 cup whole milk
  • 6 tablespoons unsalted butter room temperature
  • 1 1/2 teaspoons kosher salt or to taste
  • 1/2 teaspoon white pepper freshly ground
  • 2 tablespoons fresh chives chopped, for garnish

Method
 

  1. Place the peeled and chunked potatoes in a large pot and cover with cold water by 2 inches. Add 1 tablespoon of salt to the water. Bring to a boil over high heat, then reduce to medium-high and cook for 15-18 minutes, until the potatoes are very tender when pierced with a fork.
  2. While the potatoes cook, combine the milk and garlic cloves in a small saucepan. Heat over medium-low heat until the milk is steaming and small bubbles form around the edges, about 5-7 minutes. Don't let it boil. Remove from heat and let steep while the potatoes finish cooking.
  3. Drain the potatoes thoroughly in a colander and let them sit for 2-3 minutes to allow excess moisture to evaporate. This prevents watery mashed potatoes.
  4. Return the potatoes to the pot or transfer to a large mixing bowl. Using a potato masher or ricer, mash the potatoes until smooth. Don't use a food processor or blender, which will make them gluey.
  5. Remove the garlic cloves from the warm milk and mash them with the flat side of a knife until smooth. Stir the mashed garlic back into the milk.
  6. Gradually add the warm garlic milk to the mashed potatoes, mixing gently with a wooden spoon. Add the butter one tablespoon at a time, incorporating each piece before adding the next.
  7. Season with kosher salt and white pepper, tasting and adjusting as needed. The potatoes should be creamy but still hold their shape when scooped.
  8. Transfer to a serving bowl and garnish with chopped chives. Serve immediately while hot.

Notes

For make-ahead preparation, keep the mashed potatoes warm in a slow cooker on low heat for up to 2 hours, stirring occasionally and adding a splash of warm milk if they thicken too much. Leftover mashed potatoes can be refrigerated for up to 3 days and reheated gently on the stovetop with additional milk. For a pareve version, substitute the milk with unsweetened soy milk or vegetable broth and use vegan butter or olive oil instead of dairy butter.
