This is NOT a “recipe”, because the amount of potatoes you use will vary. But here’s an eyeball measurement based on what I did if you’d like to follow.
- 2 pounds baby potatoes (SEE NOTE BELOW)
- Sea salt for the boiling water
- 5 tablespoons butter (unsalted or salted)
- 3 tablespoons duck fat (optional SEE NOTE BELOW)
- 5 garlic cloves, chopped or minced
- 1 tablespoon fresh thyme, roughly chopped
- 1 teaspoon fresh rosemary, chopped
- 1 teaspoon fresh sage, chopped (optional)
- Fresh parmigiano reggiano cheese for topping
- Kosher salt and black pepper, to taste
- Non-stick spray
- Preheat oven to 450 degrees. Line a baking sheet with foil, or leave un-lined. Spray the bottom with nonstick spray, set aside.
- In a large pot, cover potatoes with cold water by 2-3 inches. Bring to a boil over high heat. When the water starts boiling, add a generous amount of sea salt (do NOT use table salt, it’s too salty). Reduce heat to medium-high, keep pot uncovered, and allow potatoes to boil until fork tender – about 20-25 minutes.
- Meanwhile, melt butter, and add duck fat. Stir to combine until duck fat is melted. Add garlic, thyme, rosemary, sage (if using), salt and pepper (if using unsalted butter). Stir until combined, and set aside.
- When potatoes are fork tender, drain and let them cool about 5-10 minutes. Place potatoes on your lined/unlined baking sheet. GENTLY smash each potato using the bottom of a glass, a potato masher, or fork until potato bursts open and creates a craggy surface. Spoon a little of the duck fat butter mixture over each potato. Roast for 15 to 20 minutes or until each potato is golden brown with crispy edges and bottoms. Remove baking sheet from oven and shave fresh cheese over each potato. Turn on your broiler, and pop them back into the oven until the cheese melts and is lightly toasted.
- Serve immediately.
If you’re not using baby potatoes, I recommend Yukon Golds for this recipe because they keep their shape better. You could also use Russets if you prefer. Simply chop them into large chunks prior to boiling.
If using salted butter, watch how much additional salt you add to the finished potato (taste them first).
If you cannot find duck fat, you can use one whole stick of butter instead.
