In a large pot, bring salted water to a boil. Add the cheese tortellini and cook according to package instructions until al dente. Drain and set aside.
In the same pot, heat olive oil over medium heat. Add minced garlic and sauté for about 1 minute until fragrant, being careful not to burn it.
Add the crushed tomatoes, sugar, and dried oregano to the pot. Stir well to combine and let simmer for 5-7 minutes. Season with salt and pepper to taste.
Lower the heat and pour in the heavy cream, stirring until fully incorporated and the sauce is creamy.
Mix in the chopped basil and grated Parmesan cheese, stirring until the cheese melts and the sauce thickens slightly.
Gently fold the cooked tortellini into the creamy sauce, ensuring they are well coated.
Allow to simmer for another 2-3 minutes to heat through, then adjust seasoning, if necessary.
Serve hot, garnished with additional basil leaves and a sprinkle of Parmesan cheese if desired.
Notes
