Tomatoes with Fontina Sauce and Cornichon Dressing

Before You Begin

Ingredients · Servings 4 to 6
  • ¼ cup cornichons, sliced thin on bias, plus 1 tablespoon brine
  • 3 tablespoons extra-virgin olive oil
  • 1 small shallot, minced
  • 3⁄4 teaspoon table salt, divided
  • 1 pound small tomatoes, cored and cut into 1-inch-thick wedges
  • ½ teaspoon pepper
  • 2 teaspoons fresh thyme leaves
  • ¼ teaspoon flake sea salt
  • 2 cups heavy cream
  • 2 ounces fontina cheese, shredded (½ cup)
  • 1½ ounces Parmesan cheese, grated (3⁄4 cup)
  • ¼ teaspoon table salt
Method · 45 min
  1. Toss cornichons and brine, oil, shallot, and ¼ teaspoon table salt together in bowl; set aside. Toss tomatoes gently with pepper and remaining ½ teaspoon table salt.
  2. Bring cream to boil in large saucepan over medium-high heat. Reduce heat to medium-low and simmer, whisking occasionally, until cream is reduced to 1½ cups, 15 to 18 minutes. (If mixture begins to boil over, briefly remove saucepan from heat; adjust heat as needed to maintain consistent simmer.) Off heat, add fontina, Parmesan, and salt and whisk until cheeses are fully melted and sauce is smooth, about 30 seconds.)
  3. Immediately transfer cheese sauce to large platter and spread into even layer (sauce may appear thin at first; it will thicken quickly as it cools). Arrange tomatoes in even layer over cheese sauce. Drizzle cornichon dressing over tomatoes. Sprinkle with thyme and flake sea salt. Serve.

We prefer smaller tomatoes, such as Campari or Kumato (sometimes labeled “cocktail tomatoes”); other tomato varieties, cut into rough 1- to 2-inch pieces, will also work. Shred the fontina on the large holes of a box grater and grate the Parmesan cheese on a rasp-style grater. Do not use pre-grated Parmesan here; it may contain additives that can affect the sauce’s texture. Serve with crusty bread, toasted or grilled.
