Preheat your oven to 425°F (220°C).
Place each potato between two chopsticks or wooden spoons to prevent slicing all the way through. Make thin slices, about ⅛ inch apart, across the top of each potato.
1 ½ lbs baby Yukon gold or red potatoes
In a small bowl, whisk together the olive oil, melted butter, minced garlic, thyme, salt, and pepper. Brush the mixture generously over the potatoes, making sure to get it into every slice.
3 tablespoons olive oil, 3 tablespoons unsalted butter, 4 cloves garlic, 1 tablespoon fresh thyme leaves, 1 teaspoon kosher salt, ½ teaspoon freshly ground black pepper
Place the potatoes on a baking sheet. Roast in the oven for 35-40 minutes total, basting with more garlic butter halfway through (around 20 minutes in), until they’re golden and crispy on the outside and tender on the inside.
During the last 10 minutes of roasting, sprinkle the shredded smoked jack cheese over the potatoes. Continue roasting until the cheese is melted and bubbly.
1 cup smoked jack cheese
Remove from the oven, garnish with the chives, and serve.
2 chives
