Cook 12 ounces uncooked spaghetti noodles according to the instructions on the package until al dente. Drain and set aside.
Meanwhile, add ⅓ cup extra virgin olive oil to a large 14-inch skillet and heat over medium-low heat. Once the oil is shimmering but not smoking, add 2 tablespoons minced garlic and cook for about 1 minute, until fragrant and sizzling, but not yet browning.
Add 4 cups halved grape or cherry tomatoes, 1 ½ teaspoons granulated sugar, 1 teaspoon salt, and ½ teaspoon ground black pepper and stir to combine. Cover and cook for 10-15 minutes, until the tomatoes are soft and can be easily smashed with the back of a spoon.
Add ½ cup chopped fresh basil and the cooked spaghetti noodles to the skillet and stir until the noodles are fully coated and heated through.
Remove the skillet from the heat and stir in 1 ½ cups freshly grated mozzarella cheese and ⅔ cup freshly grated parmesan cheese. Top with additional parmesan cheese, fresh basil, and a crack of black pepper before serving
Notes
Storage: Keep leftovers in an airtight container in the fridge for up to 5 days. Reheat in the microwave or a skillet. Don’t freeze, the texture won’t hold up.
