In a large oven-safe baking dish, combine the halved cherry tomatoes with the minced garlic. Add dried oregano, red pepper flakes, and season generously with salt and freshly ground black pepper.
Drizzle two tablespoons of extra virgin olive oil over the mixture and toss gently to coat the tomatoes.
Create a well in the center of the tomato mixture and place the block of feta cheese in this space, pressing it down slightly.
Drizzle the remaining two tablespoons of olive oil over the feta cheese.
Place the baking dish in the preheated oven and bake for approximately 30 minutes until the tomatoes are blistered and the feta is softened.
While the feta and tomatoes bake, bring a pot of salted water to a boil and cook the pasta according to package instructions until al dente. Reserve 1 cup of the starchy pasta water before draining.
Once baked, carefully remove the dish from the oven and mash the softened feta with a fork, mixing it with the roasted tomatoes until creamy.
Add the drained pasta directly into the baking dish and stir together, adding reserved pasta water gradually to reach your preferred sauce consistency.
Taste and adjust seasoning with additional salt and pepper if necessary. If using, sprinkle lemon zest over the dish.
Top with fresh basil leaves before serving.
Notes
Serve straight from the baking dish for a rustic look.
