Preheat your oven to 400°F (200°C).
In a 9x13 inch baking dish, combine the red cherry tomatoes, yellow cherry tomatoes, minced garlic, olive oil, salt, and black pepper. Toss until well coated.
Place the unwrapped package of Boursin cheese directly in the center of the baking dish, surrounded by the tomatoes.
Bake for 35 minutes until the tomatoes burst and the cheese is softened and bubbly.
While the tomatoes and cheese bake, boil a large pot of salted water and cook the pasta according to package directions. Drain, reserving 1/2 cup of pasta water.
Remove the baking dish from the oven. Immediately mash the baked cheese and tomatoes together with a fork to create a creamy sauce.
Stir the cooked pasta and freshly chopped parsley into the sauce, adding a splash of reserved pasta water if needed to reach your desired consistency.
