Roast the Red Peppers: Preheat your oven's broiler. Place the red bell peppers on a baking sheet and broil them for approximately 20 minutes, turning them occasionally until the skins are charred and blistered. Once done, transfer the peppers to a bowl and cover it tightly with plastic wrap. Allow the peppers to steam for 10 minutes; this will loosen their skins. When cooled, peel off the charred skin, remove the seeds, and chop the peppers roughly.
Cook the Pasta: While the peppers are steaming, bring a large pot of salted water to a boil. Once boiling, add the pasta and cook according to the package instructions until al dente. Before draining, reserve about 1 cup of the pasta cooking water. After reserving the water, drain the pasta and set it aside.
Prepare the Sauce: In a high-speed blender or food processor, combine the peeled and chopped roasted red peppers, heavy cream, minced garlic, grated Parmesan cheese, Italian seasoning, and a generous pinch of salt and pepper. Blend on high until the mixture is perfectly smooth and creamy.
Heat the Sauce: In a large skillet, heat the olive oil over medium heat. Once heated, pour in the blended red pepper sauce and cook for 2-3 minutes, stirring occasionally, until warmed through. If the sauce appears too thick, gradually add some of the reserved pasta water until you achieve your desired consistency.
Combine Pasta and Sauce: Add the drained pasta directly to the skillet with the warm sauce. Gently toss together until every strand of pasta is generously coated with the creamy red pepper sauce.
Serve: Plate the pasta immediately, garnishing each serving with fresh basil leaves and an extra sprinkle of grated Parmesan cheese if desired.
Notes
To elevate your dish, serve it in a large, shallow bowl with whole basil leaves and a drizzle of olive oil.
