Preheat your oven to 400°F (200°C). This high temperature is crucial for properly caramelizing the tomatoes and getting that perfect feta texture.
Place cherry tomatoes in a 9×13 inch baking dish. Arrange them so they form a single layer covering most of the dish.
Create a space in the center of the tomatoes and place the block of feta cheese there. The block should sit nestled among the tomatoes, not on top of them.
Drizzle everything with 1/3 cup olive oil making sure to coat both the tomatoes and the feta generously. The oil creates the luscious base for your sauce.
Sprinkle the minced garlic, red pepper flakes, dried oregano, salt and pepper over the tomatoes and feta. Distribute the seasonings evenly for consistent flavor.
Bake in the preheated oven for 25-30 minutes until the tomatoes have burst and the feta has softened and turned slightly golden on top. You’ll know it’s ready when the tomatoes are wrinkly with some charred spots.
While the tomatoes and feta are baking, cook the pasta in heavily salted water according to package directions until al dente. Reserve 1/2 cup of pasta water before draining.
Remove the baking dish from the oven and immediately mash the feta and tomatoes with a fork or spoon, creating a creamy sauce. If it seems too thick, add a splash of the reserved pasta water.
Add the drained pasta directly to the baking dish and toss until every piece is coated with the tomato-feta sauce. The residual heat will help the sauce cling to the pasta.
Finish with the remaining olive oil, fresh basil, and additional black pepper. Taste and adjust seasonings as needed before serving immediately.
