Ingredients
- Tilapia fillets: bring a tender flaky texture and cook quickly Choose fillets that are firm and smell fresh with no fishy aroma
- Butter: offers richness and helps develop the base flavor Go for Europeanstyle butter if you want even more buttery depth
- Medium onion: diced for sweetness and savory notes A yellow onion works beautifully
- Fresh garlic cloves: add wonderful aroma and background flavor Look for plump garlic bulbs with tight skins
- Roasted peppers: both chopped and pureed make the sauce sweet complex and colorful Use homemade or quality jarred peppers with no added sugar
- Heavy cream: creates the luscious texture and balances the acidity of peppers Always check for a thick creamy consistency
- Grated Parmesan cheese: brings a salty nutty punch Shred the cheese yourself from a wedge for top flavor
- Salt and black pepper: for simple seasoning Always taste as you go
- Chopped parsley: to garnish brings fresh color and livens up the dish Go for bright green bunches
Step-by-Step Instructions
- Prepare and Cook Tilapia:
- Melt two tablespoons of butter in a wide nonstick skillet set over medium heat Once the butter foam subsides nestle in the tilapia fillets Season them on both sides with salt and pepper Let the fish cook for between three to four minutes on each side until the flesh turns opaque and flakes gently when nudged with a fork Use a fish spatula to lift out the tilapia onto a plate and keep warm
- Start the Sauce Base:
- To the same pan with the fond and any remaining butter add the final tablespoon of butter along with the diced onion Stir frequently over mediumlow heat for about five minutes until the onion is soft translucent and sweet but not browned
- Layer on the Roasted Peppers and Garlic:
- Add minced garlic stirring constantly for about thirty seconds so it releases its fragrance without burning Stir in both the chopped and pureed roasted peppers Allow this to gently cook for another five minutes stirring occasionally so the flavors meld into a single bright orange sauce
- Enrich with Cream and Cheese:
- Reduce the heat to low Pour in the heavy cream and sprinkle the Parmesan cheese into the pan Immediately turn off the burner and stir constantly The cheese will melt and the sauce will thicken Taste a spoonful and adjust with more salt or pepper if you feel the sauce needs it
- Return Fish to Pan and Finish:
- Carefully slide the cooked tilapia filets back into the warm sauce Baste the fish with spoonfuls of the creamy pepper sauce so they are well covered Let the fish sit in the sauce for another minute to blend the flavors
- Garnish and Serve:
- Before taking the dish to the table shower the top with a handful of freshly chopped parsley and more Parmesan if you wish The dish is ready to enjoy while bubbling hot

I absolutely love how the roasted peppers balance richness with their gentle smoky sweetness Once my son helped me blend the peppers for the first time and he still calls this his favorite fish dinner
Storage Tips
Store leftovers in an airtight glass container in the fridge for up to two days The sauce may thicken as it sits so add a splash of cream or milk before reheating for a silky finish Gently reheat on low heat to avoid separating the cream
Ingredient Substitutions
You can use another mild white fish such as cod or haddock if you do not have tilapia For a lighter sauce try halfandhalf instead of heavy cream If you are out of Parmesan a touch of Pecorino Romano will work but add less since it is saltier
Serving Suggestions
This dish pairs perfectly with crusty bread or over buttered noodles to soak up the luscious sauce For extra green on the plate add a simple salad of arugula with lemon or steamed green beans with olive oil
