Start by roasting the red pepper. Preheat the oven to 450°F (230°C). Place the bell peppers on a baking sheet and roast for about 20-25 minutes, turning occasionally, until the skins are blistered and charred. Remove from the oven and place them in a bowl covered with plastic wrap for 10 minutes. This will help steam the skins off. Once cooled, peel the skins off and remove the seeds.
While the peppers are cooling, cook the pasta according to package instructions in a large pot of salted boiling water until al dente. Drain and set aside.
In a blender, combine the roasted red peppers, heavy cream, minced garlic, Italian seasoning, and a pinch of salt and pepper. Blend until smooth and creamy.
In the same pot used for the pasta, heat the olive oil over medium heat. Pour in the red pepper cream sauce and warm it through for about 2-3 minutes, stirring constantly.
Add the cooked pasta to the sauce, along with the grated Parmesan cheese. Toss everything together until the pasta is well coated with the sauce. If the sauce is too thick, you can add a tablespoon of pasta water to achieve your desired consistency.
Taste the pasta and adjust the seasoning with more salt, pepper, or crushed red pepper flakes for heat if desired.
Serve the creamy roasted red pepper pasta hot, garnished with fresh basil leaves and additional Parmesan cheese if desired.
