In a large baking dish, combine the cherry tomatoes, minced garlic, red pepper flakes, olive oil, salt, and black pepper. Toss until everything is well coated.
Make a space in the center of the dish and place the block of feta cheese. Drizzle a little more olive oil over the feta and season with a pinch of salt and pepper.
Bake in preheated oven for 30 minutes, until the tomatoes are burst and caramelized and the feta is soft and golden.
While the feta and tomatoes are baking, cook the pasta according to package instructions until al dente. Reserve 1/2 cup of pasta water, then drain the pasta.
Once the feta and tomatoes are done baking, remove from the oven and use a fork to mash the feta cheese into the tomatoes, creating a creamy sauce.
Add the cooked pasta to the baking dish, tossing everything together. If the sauce is too thick, add reserved pasta water a little at a time until you reach your desired consistency.
Taste and adjust seasoning if necessary.
Serve warm, garnished with fresh basil leaves and a sprinkle of grated Parmesan cheese.
Notes
Adjust seasoning to taste and use fresh basil for garnish.
