Preheat oven to 400°F (200°C).

Place the cherry tomatoes and smashed garlic in a 9x13 baking dish. Place the block of feta in the center.

Drizzle everything generously with olive oil, salt, pepper, and red pepper flakes. Toss the tomatoes to coat.

Bake for 35 minutes until the tomatoes burst and the feta is very soft.

Meanwhile, boil the pasta in salted water until al dente. Drain, reserving 1/2 cup of pasta water.

Remove the baking dish from the oven and immediately mash the feta and tomatoes together with a fork to form a creamy sauce.

Stir in the cooked pasta, adding a splash of pasta water if needed. Garnish with fresh basil and serve.
