Cook the pasta according to package instructions until al dente. Drain and set aside, reserving 1/2 cup of pasta water.
In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute, until fragrant but not browned.
Stir in the drained diced tomatoes and cook for 2-3 minutes, allowing the flavors to meld.
Reduce the heat to low and pour in the heavy cream. Add the Italian seasoning, salt, and pepper. Stir well to combine and let simmer for 5 minutes.
Add the cooked pasta to the skillet, tossing to coat in the creamy sauce. If the sauce is too thick, add reserved pasta water a little at a time until desired consistency is reached.
Stir in the grated Parmesan cheese until melted and creamy. Adjust seasoning if necessary.
Serve hot, garnished with fresh basil leaves.
