Bring a large pot of salted water to a boil and cook the pasta according to package instructions. I always cook it until just al dente so it doesn’t turn mushy later. Before draining, I reserve about ½ cup of pasta water to adjust the sauce if needed.
In a large skillet, heat olive oil and butter over medium heat until melted. I add the minced garlic and sun dried tomatoes, stirring gently so the garlic doesn’t burn. This step releases their aromas and infuses the oil with flavor.
Pour in the chicken broth and let it simmer for a minute to reduce slightly. I then add the heavy cream, Italian seasoning, red pepper flakes, salt, and pepper. The sauce thickens as it simmers, turning smooth and creamy.
I lower the heat and stir in the freshly grated Parmesan cheese. The cheese melts into the sauce, making it rich and glossy. If the sauce feels too thick, I add a splash of reserved pasta water.
Finally, I add the cooked pasta directly into the skillet and toss everything together. The pasta gets fully coated in the sauce. I finish with fresh basil and an extra sprinkle of Parmesan before serving.
