1Preheat oven to 400°F. Add cherry tomatoes, sliced zucchini, sliced shallot, and garlic cloves to a 9x13 baking dish. Place the Boursin cheese in the center, drizzle with olive oil, and season with Italian seasoning, salt, pepper, and red pepper flakes.
2Bake the baking dish for 30–35 minutes.
3Cut chicken breasts into bite-sized pieces and season with garlic powder, salt, and pepper.
4Cook the chicken in a skillet over medium-high heat until browned and cooked through.
5Cook the rigatoni pasta until just al dente.
6Remove the baking dish from the oven, burst the roasted tomatoes, and mash the garlic and Boursin together.
7Add the cooked pasta and chicken to the baking dish along with the basil and lemon juice, then toss until coated.
