1. Preheat your oven to 400°F (200°C).
2. In a baking dish, combine the cherry or grape tomatoes, 4 cloves of garlic, and a few tablespoons of olive oil. Season generously with Greek seasoning, red chili flakes, and freshly ground black pepper. Place the 6 oz block of feta in the center of the dish.
3. Bake at 400°F for approximately 30 minutes, or until the feta starts to lightly brown and the tomatoes begin to burst.
4. While the feta and tomatoes are baking, cook the 8 ounces of bowtie pasta according to package directions. Before draining, reserve 1/4 cup of the pasta water.
5. Once baked, remove the dish from the oven. Using a fork, mash the roasted feta and tomatoes together until they form a rustic sauce.
6. Add the cooked bowtie pasta and the reserved pasta water to the baking dish. Toss everything together until well combined and the pasta is coated with the sauce.
7. Garnish with freshly chopped basil, if desired, before serving.
