Begin by bringing a large pot of salted water to a boil. Add your 8 oz of pasta and cook according to package instructions until al dente. Reserve about 1/2 cup of pasta water before draining — this starchy water will help adjust the sauce’s consistency later.
While the pasta cooks, heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the minced garlic and sauté for about 1-2 minutes until fragrant and golden but not burnt.
Pour in the canned diced tomatoes with their juices. Stir and let the mixture simmer gently for 5-7 minutes to reduce slightly and concentrate the flavors.
Lower the heat and slowly add 1 cup of heavy cream, stirring consistently to combine. Let the sauce bubble gently for another 3-4 minutes so it thickens into a luxuriously creamy texture.
Add 1/2 cup of freshly grated Parmesan cheese, stirring until melted and smooth. Season with salt and pepper to taste. If the sauce feels too thick, stir in a splash of the reserved pasta water until you reach your desired consistency.
Add the drained pasta directly into the skillet, tossing gently to coat every piece with the creamy garlic tomato sauce. Allow it to warm through for a minute or two so the flavors meld beautifully.
Remove from heat and sprinkle 1/4 cup of chopped fresh basil over the pasta. Give it a final gentle toss and serve immediately for the best flavor and texture.
