In a large baking dish, combine the halved cherry tomatoes, minced garlic, olive oil, dried oregano, red pepper flakes, salt, and pepper. Mix well to ensure the tomatoes are coated.
Place the block of feta cheese in the center of the dish, surrounded by the seasoned tomatoes. Drizzle a little more olive oil over the feta.
Bake in the preheated oven for about 25 minutes, or until the feta is soft and the tomatoes are bursting.
While the feta and tomatoes are baking, bring a pot of salted water to boil and cook the penne pasta according to package instructions until al dente. Drain and set aside.
Once the feta and tomatoes are done baking, remove the dish from the oven and gently mash the feta cheese and tomatoes together with a fork to create a creamy sauce.
Add the cooked penne pasta to the baking dish, tossing everything together until the pasta is well coated with the feta-tomato mixture. Adjust seasoning with additional salt and pepper if necessary.
Serve warm, garnished with fresh basil leaves and a sprinkle of grated Parmesan cheese.
Notes
Adjust red pepper flakes to taste for desired spiciness.
