Begin by preheating your oven to 400°F (200°C) so it's ready for the baking process.
In a large baking dish, combine the halved cherry tomatoes, minced garlic, olive oil, dried oregano, red pepper flakes, salt, and black pepper. Stir well to ensure all the tomatoes are evenly coated with the flavorful mixture.
Create a small nest in the center of the dish and place the block of feta cheese right in the middle, surrounded by the seasoned tomatoes. Drizzle a little more olive oil over the top of the feta for added richness.
Place the dish in the preheated oven and bake for approximately 25 minutes, or until the feta cheese softens and the tomatoes are bursting and caramelizing.
While the feta and tomatoes are baking, fill a large pot with salted water and bring it to a boil. Once boiling, add the penne pasta and cook according to the package instructions until it reaches an al dente texture. After cooking, drain the pasta and set it aside.
When the baking time is complete, carefully remove the dish from the oven. Use a fork to gently mash the baked feta cheese and the tomatoes together, forming a creamy sauce.
Add the cooked penne pasta to the baking dish. Toss everything together thoroughly until the pasta is well coated with the creamy feta-tomato sauce. Taste and adjust the seasoning if needed, adding more salt and pepper to your liking.
Serve the dish warm, garnished with fresh basil leaves for a burst of flavor, and finish with a generous sprinkle of freshly grated Parmesan cheese on top.
Notes
Adjust red pepper flakes to taste for desired spiciness.
