By á-4922

Ingredients

• 2 pounds Yukon Gold potatoes (4 to 6 medium), peeled, cut into 1/2-inch-thick slices, rinsed well, and drained
• Table salt
• 6 tablespoons unsalted butter
• 2 medium garlic cloves, minced or pressed through a garlic press (about 2 teaspoons)
• 1 - 1 1/2 cups whole milk
• 4 ounces mozzarella cheese, shredded (about 1 cup) (see note)
• 4 ounces Gruyère cheese, shredded (about 1 cup) (see note)
• Ground black pepper

Preparation

Step 1

1. Place potatoes in large saucepan; add water to cover by 1 inch and add 1 tablespoon salt. Partially cover saucepan with lid and bring potatoes to boil over high heat. Reduce heat to medium-low and simmer until potatoes are tender and just break apart when poked with fork, 12 to 17 minutes. Drain potatoes and dry saucepan.
2. Transfer potatoes to food processor; add butter, garlic, and 11/2 teaspoons salt. Pulse until butter is melted and incorporated into potatoes, about ten 1-second pulses. Add 1 cup milk and continue to process until potatoes are smooth and creamy, about 20 seconds, scraping down sides halfway through.
3. Return potato mixture to saucepan and set over medium heat. Stir in cheeses, 1 cup at a time, until incorporated. Continue to cook potatoes, stirring vigorously, until cheese is fully melted and mixture is smooth and elastic, 3 to 5 minutes. If mixture is difficult to stir and seems thick, stir in 2 tablespoons milk at a time (up to ½ cup) until potatoes are loose and creamy. Season with salt and pepper. Serve immediately.
