Meanwhile, heat the olive oil in a large saute pan or skillet over medium heat. Add the onion and saute until softened, about 2-3 minutes. Add the garlic and cook for 30 seconds longer.

Increase the heat to medium-high and add the cherry tomatoes, sugar, kosher salt, and black pepper. Cook for about 7-8 minutes, tossing occasionally, until the tomatoes begin to burst. Crush them lightly with a wooden spoon or spatula to release their juices and create a chunky sauce.

Add the cooked pasta back to the pan with the tomatoes, along with crushed red pepper, mozzarella pearls, and fresh basil. Toss to combine. Add a splash of reserved pasta water as needed to loosen the sauce. Serve with shredded Parmesan.
