**Cook the pasta**:
Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Reserve 1/2 cup of pasta water, then drain the rest.
**Sauté the garlic**:
In a large skillet, heat olive oil over medium heat. Add the minced garlic and sauté for 1–2 minutes, until fragrant but not browned.
**Add the tomatoes**:
Stir in the crushed or diced tomatoes, dried oregano, and red pepper flakes (if using). Simmer for 5–7 minutes, allowing the flavors to meld.
**Make it creamy**:
Reduce the heat to low and stir in the heavy cream. Add the Parmesan cheese, whisking until melted and smooth.
**Incorporate the basil**:
Stir in the chopped basil and season the sauce with salt and pepper to taste.
**Combine with pasta**:
Add the cooked pasta to the skillet, tossing to coat in the sauce. If needed, add a splash of reserved pasta water to loosen the sauce.
**Serve**:
Plate the pasta and garnish with additional Parmesan cheese and fresh basil. Serve immediately.
