01 - Preheat the oven to 400°F.
02 - In a large baking dish, combine cherry tomatoes and garlic. Drizzle with olive oil and season with salt, pepper, and red pepper flakes. Toss thoroughly to coat.
03 - Place the block of feta cheese in the center of the dish, nestling it among the tomatoes. Drizzle the top of the feta with a little additional olive oil.
04 - Bake for 30 minutes, or until the tomatoes have burst and released their juices, and the feta has turned golden brown on top and softened.
05 - While the cheese roasts, cook the pasta in a large pot of boiling salted water according to package directions until al dente. Reserve 1/2 cup of the starchy pasta water before draining.
06 - Remove the baking dish from the oven. Use a spoon to mash the feta and roasted tomatoes together until a smooth, creamy sauce forms.
07 - Add the drained pasta and half of the fresh basil leaves to the baking dish. Toss everything together vigorously, adding the reserved pasta water as needed to achieve a glossy, coating consistency.
08 - Plate the pasta immediately and garnish with the remaining fresh basil leaves.
