Ingredients

  • 4 (3/4-pound) russet potatoes, scrubbed
  • 3 tablespoons olive oil, divided
  • Kosher salt and freshly cracked black pepper
  • 1 tablespoon butter, plus extra for serving, softened
  • 3 cloves garlic, minced
  • 1 teaspoon red pepper flakes
  • 1 bunch Swiss chard, stems discarded and leaves finely chopped
  • 1/2 cup part-skim ricotta cheese
  • 1/2 cup shredded smoked mozzarella, plus extra for topping
  • 1/4 cup grated Parmesan, plus extra for topping

Method

  • Preheat the oven to 400 degrees F.
  • Pierce around the potatoes with a fork and put them on a sheet tray.
  • Drizzle with 2 tablespoons olive oil and season, to taste, with salt and black pepper.
  • Slide them onto the center rack in the oven and bake for 1 hour, then let them cool slightly.
  • Using a paring knife, slice the potatoes lengthwise and scoop the flesh into a large mixing bowl.
  • Make sure to leave a 1/2-inch thick wall of flesh along the inside of the skin.
  • In a heavy-bottomed skillet, melt the butter with the remaining tablespoon of olive oil over medium heat.
  • Once warm, saute the garlic and red pepper flakes until fragrant, about 1 minute.
  • Add the Swiss chard leaves and continue sauteing until they are soft and tender and all liquid has been evaporated.
  • Adjust the seasonings with salt and pepper, then transfer the vegetables to a bowl.
  • Stir the ricotta cheese, mozzarella and Parmesan into the potatoes and season with salt and pepper, to taste.
  • Mash until the filling is creamy, then fold in the Swiss chard.
  • Using a small spoon, scoop the filling back into the potatoes and pat down the mound so it is secure.
  • Sprinkle more mozzarella and Parmesan over the tops of the potatoes and set them onto a baking sheet.
  • Bake them once more to heat through and to melt the cheese, about 15 to 20 minutes.
  • Remove from the oven and arrange on a serving platter.
  • Serve with softened butter, if desired.
