Units Scale
  • 2 Large Russet Potatoes (about 1.51.75 lb altogether)
  • 1/3 cup (75g) melted butter (I used salted)
  • 3 Tbsp (12g) Freshly Grated Parmeggiano Reggiano (or other Parmesan cheese)
  • 1 Tbsp (23 cloves) Grated Garlic
  • 1/4 tsp Dried Oregano
  • 1/2 tsp Kosher Salt (3/4 tsp if using Unsalted Butter)
  • 1/4 tsp Black Pepper
  • 2 Tbsp Chopped Parsley, plus extra for garnish
  • 3/4 oz (22g) Pancetta, chopped into tiny cubes


  1. Preheat oven to 400F (375F for Convection). Slice the peeled sides and ends from the potatoes so that the remaining potato is an elongated, peeled (or mostly peeled) cube or rectangle.  Then slice the elongated cube into 1/2-inch slices.
  2. Positioning the slices between 2 chopsticks (or similar), and using a sharp knife, score vertical and then horizontal lines onto each cube. Lay the cut pieces on a sprayed or parchment-covered baking sheet. You should have around 16 pieces.
  3. In a small bowl or measuring cup, melt the butter in the microwave. Then stir in the remaining ingredients, except for the pancetta.
  4. Brush the bottoms of each potato slice with the butter mixture and set back on the pan or parchment.
  5. Then brush all of the tops, with more of the butter mixture, making sure they each have some parmesan and garlic.  Place the pan of potatoes in the oven for 20 minutes. Remove the pan, brush with butter mixture again, then sprinkle a few bits of pancetta over each potato slice. You should be able to use all of the butter mixture. Return to oven for 20 more minutes.
  6. Remove from pan, sprinkle with more parsley and/or Parmeggiano-Reggiano, and serve.
