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, being careful not to burn it.
Add the drained diced tomatoes to the skillet and cook for 3-4 minutes, stirring occasionally.
Pour in the heavy cream and stir in the Italian seasoning. Let the mixture simmer for 2-3 minutes until slightly thickened.
Season with salt and pepper to taste. Add the cooked pasta to the skillet, tossing to coat in the creamy sauce. If the sauce is too thick, add a bit of the reserved pasta water to reach desired consistency.
Stir in the grated Parmesan cheese until melted and well combined. Remove from heat.
Serve immediately, garnished with fresh basil leaves.
