Preheat your oven to 400°F (200°C).
In a large baking dish, combine the halved cherry tomatoes, minced garlic, olive oil, salt, black pepper, red pepper flakes (if using), and dried oregano. Stir well to coat the tomatoes.
Place the block of feta cheese in the center of the tomato mixture, then drizzle a little more olive oil over the feta.
Bake in the preheated oven for about 30 minutes, or until the tomatoes are juicy and bursting, and the feta is golden and softened.
While the feta and tomatoes are baking, cook the pasta according to package instructions in a medium pot of salted boiling water until al dente. Drain the pasta using a colander.
Once the baking is done, remove the dish from the oven. Using a fork, mash the feta and mix it with the tomatoes until creamy.
Add the cooked pasta to the baking dish and toss everything together until the pasta is well coated with the sauce.
Sprinkle the lemon zest and chopped fresh basil over the pasta and toss gently to combine.
Serve warm, garnished with additional fresh basil if desired.
