Prosciutto, Watercress, and Fontina Toasties

This sophisticated take on the classic grilled cheese features a refined blend of salty prosciutto, creamy fontina, and peppery watercress. By crisping the ham in the oven before assembly, you add a wonderful texture that contrasts beautifully with the melted Italian cheese and soft Pullman loaf. It is a grown-up toasted sandwich that balances rich, savoury notes with a fresh hit of greenery.

As a high-protein lunch or a light supper, these toasties are incredibly satisfying and simple to prepare. Using a frying pan ensures a perfectly golden, buttery crust that holds the gooey filling together. Serve these triangles warm as a decadent weekend treat or alongside a light tomato soup for a more substantial meal.

Ingredients for Prosciutto, Watercress, and Fontina Toasties

  • 8 thin slices prosciutto (about 90g )

  • 8 1/2 "-thick slices Pullman bread

  • 230g Fontina cheese, thinly sliced

  • 3/4 cup trimmed chopped watercress

  • 1/4 cup unsalted butter, room temperature

Preheat oven to 177°C. Bake prosciutto on a parchment-lined baking sheet until it darkens and shrinks slightly, 6-8 minutes. Let cool (meat will crisp as it cools).

Top 4 slices of bread with half of cheese, prosciutto (breaking to fit), watercress, then remaining cheese (it will bind as it melts) and bread; butter tops.

Heat a large skillet over medium heat. Working in 2 batches, cook sandwiches, butter side down, pressing firmly, until bottom is golden brown. Butter tops, turn, and cook until golden brown and cheese is melted, about 4 minutes. Transfer to a wire rack; let cool slightly. Remove crusts and cut each sandwich into 4 triangles.
