Preheat oven to 400°F / 200°C.
Toss tomatoes + garlic with olive oil in a baking dish. Nestle the feta in the center. Season with salt + pepper.
Bake for 30 min until tomatoes burst and feta is golden.
Meanwhile, cook pasta. Save a bit of pasta water.
Mash the feta + tomatoes into a creamy sauce. Stir in pasta and a splash of the water to bring it together.
Add basil. Eat. Freak out a little.
