Heat the oil in a skillet over medium heat. Add the tomatoes, garlic, red pepper flakes and cook, covered slightly. Swirl the pan often, until the tomatoes blister and start to burst, 10-12 minutes. Crush the tomatoes to release their juices and simmer, uncovered, to thicken slightly. Remove pan from heat and set aside.
Transfer the orecchiette to the skillet with tomatoes; set over medium heat. Cook, stirring until sauce is thick and coats the pasta about 1 minute. Stir in the bocconcini, taste and season with salt and pepper. Serve with basil and enjoy hot!
