Heavy cream adds richness and balances any heat, creating a creamy mouthfeel that even those sensitive to spice can enjoy. For garnish, a drizzle of sour cream and a sprinkle of Parmesan elevate the presentation and taste.

If you prefer, garnish with extra Parmesan or a swirl of sour cream for added creaminess and visual appeal.
If jarred or canned roasted peppers aren’t available, roast fresh bell peppers in the oven until charred, steam to loosen skins, cool, peel, then purée. Directions for roasting fresh bell peppers are provided below.
*How to Roast Fresh Bell Peppers-
Preheat the broiler and line a baking sheet with foil. Slice peppers in half, remove stems and seeds, and lay them cut‑side down. Broil for about 10–15 minutes until skins are charred.
Remove from the oven and tent the peppers with foil to steam for 8 minutes. Once cooled slightly, peel off the charred skin. There’s no need to remove every bit of skin; just remove the large charred pieces.
