📖 Instructions

1. Prepare the Vegetables for Roasting: Preheat your oven to 400°F (200°C). Wash and thoroughly dry the red bell peppers. Cut them in half, remove the seeds and white membranes. Peel and quarter the red onion. Peel the garlic cloves, leaving them whole. No need to chop them up, the oven will soften them beautifully.
2. Roast the Vegetables: On a large baking sheet, toss the halved red peppers, quartered red onion, and whole garlic cloves with 2 tablespoons of olive oil. Spread them out in a single layer. Sprinkle generously with salt and black pepper. Roast for 25-30 minutes, or until the peppers are softened, slightly charred, and the garlic is fragrant and tender. Keep an eye on the garlic so it doesn't burn.
3. Sauté the Aromatics (if using fresh instead of roasted): While the vegetables are roasting, or if you prefer a non-roasted base, heat 1 tablespoon of olive oil in a large sauté pan over medium heat. Add the finely chopped red onion and cook until softened, about 5 minutes. Add the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic.
4. Make the Sauce: Carefully transfer the roasted peppers, onion, and garlic (including any delicious pan juices) to a high-speed blender. Add the canned crushed tomatoes, vegetable broth, and 1/4 cup of heavy cream (or plant-based alternative). Blend until the sauce is completely smooth and creamy. If it’s too thick, add a little more vegetable broth, one tablespoon at a time, until you reach your desired consistency.
5. Adjust Seasoning: Pour the blended sauce into a clean large pot or back into the sauté pan you used earlier. Heat over medium-low heat. Taste the sauce and adjust seasonings as needed. You might want a pinch more salt, pepper, or even a tiny bit of sugar to balance the acidity of the tomatoes, though the roasted peppers usually provide enough natural sweetness.
6. Cook the Pasta: While the sauce is simmering, cook your favorite pasta according to package directions. Make sure to cook it al dente – that's Italian for 'to the tooth,' meaning it should be firm to the bite. Before draining, reserve about 1 cup of the starchy pasta water; it’s liquid gold for making your sauce extra silky.
7. Combine and Finish: Drain the cooked pasta and add it directly to the pot with the creamy red pepper sauce. Add the remaining 1/4 cup of heavy cream and half of the grated Parmesan cheese (if using). Toss everything together until the pasta is thoroughly coated. If the sauce seems too thick, add a splash of the reserved pasta water, a tablespoon at a time, until it reaches a beautiful, smooth consistency.
8. Serve: Divide the pasta among serving bowls. Garnish generously with fresh basil leaves and the remaining grated Parmesan cheese. A drizzle of good quality extra virgin olive oil before serving wouldn't hurt either. Enjoy this comforting dish warm!
