Preheat oven to 400ºF.
In a large bowl, mix together Ricotta con Latte®, Parmesan, 1 cup Fontina, garlic, crushed red pepper flakes, salt, pepper, basil, and lemon juice. Gently stir in cherry tomatoes and olive oil.
Transfer dip to a small cast-iron skillet or baking dish and top with remaining 1/2 cup Fontina.
Bake 20 to 25 minutes, until bubbly and golden brown.
Garnish with basil and serve with baguette slices.
