Instructions
- Roast the garlic:
Preheat oven to 375°F (190°C). Slice the top off the garlic head, drizzle with olive oil, wrap in foil, and roast for 1 hour. Let cool, then squeeze out the roasted cloves. - Make the cream sauce:
In a blender or food processor, combine roasted garlic, milk, cream cheese, nutmeg, smoked paprika, parsley, onion powder, Gruyère, and Parmigiano-Reggiano. Blend until smooth. - Prepare the potatoes:
Use a mandoline or sharp knife to slice the Yukon Gold potatoes evenly for uniform baking. - Assemble the dish:

Cover the dish with aluminum foil and bake at 400°F (200°C) for 45 minutes. - Finish baking uncovered:
Remove foil and bake for an additional 15–20 minutes, until the top is golden, bubbly, and the potatoes are fork-tender. - Garnish and serve:
Let the dish cool slightly. Sprinkle with chopped chives, extra Parmigiano, and a dash of black pepper before serving.
