Combine the oil, roasted peppers, onions, garlic, basil, salt, cayenne, and black pepper in a medium saucepan over high heat and cook for 3 minutes. Stir in the stock and the cream and bring to a full boil. Reduce the heat and simmer, stirring occasionally, for about 8 minutes.
Remove from the heat and puree in a food processor or blender for about 2 minutes. Serve immediately or store, refrigerated, in an airtight container for up to 24 hours. Reheat in a saucepan over low heat.
