Ingredients

  • 1/4 cup plus 2 tablespoons pine nuts

  • 1/4 cup freshly grated Parmigiano-Reggiano cheese

  • 3 tablespoons freshly grated Pecorino Romano cheese

  • 1 garlic clove, smashed, plus 1 head garlic, halved crosswise

  • 1 cup extra-virgin olive oil

  • 4 cups basil leaves

  • Salt and freshly ground pepper

  • 3/4 pound Jerusalem artichokes, peeled and cut into 1/2-inch dice

  • 3/4 pound parsnips, peeled and cut into 1/2-inch dice (2 cups)

  • 2 thyme sprigs

  • 2 tablespoons aged balsamic vinegar

  • Ten 1/2-inch-thick slices of rustic white bread

  • 1/4 cup sliced almonds

  • 1/2 pound imported Fontina cheese, thinly sliced

Directions

  1. Preheat the oven to 400°. In a food processor, combine the pine nuts with the Parmigiano-Reggiano, Pecorino Romano, smashed garlic clove and 3/4 cup of the olive oil and pulse until smooth. Add the basil and pulse until finely chopped. Season the pesto with salt and pepper.

  2. In a roasting pan, toss the Jerusalem artichokes with the parsnips, thyme sprigs, garlic head and the remaining 1/4 cup of olive oil. Season with salt and pepper. Roast the vegetables for 45 minutes, stirring occasionally, until tender and golden. Discard the garlic and thyme; stir in the vinegar.

  3. Meanwhile, arrange the bread slices on a large baking sheet and toast in the oven until lightly browned, about 8 minutes. Spread the almonds in a pie plate and toast until golden, about 5 minutes.

  4. Preheat the broiler and position a rack 6 inches from the heat. Spread each toast with a rounded tablespoon of the pesto. Top with the roasted vegetables and Fontina. Broil for about 1 minute, until the cheese is just melted. Sprinkle with the toasted almonds and serve right away.

Make Ahead

The roasted root vegetables and basil pesto can be refrigerated separately, covered, overnight.
