Ingredients
- Fresh tilapia fillets: Choose firm fillets with a mild aroma avoid any with a fishy smell
- Butter: Gives richness to both the fish and the sauce opt for unsalted so you control the seasoning
- Medium onion diced: Brings a base of sweetness and depth look for a firm onion with shiny skin
- Garlic clove: Essential for aroma use plump cloves for best flavor
- Roasted peppers both chopped and pureed: Roasted peppers give the sauce its signature flavor and silky texture use freshly roasted or good quality jarred ones packed in water instead of oil
- Heavy cream: Creates that luscious luxurious sauce select cream with a high fat content for smoothness
- Grated Parmesan cheese: Adds umami and a bit of salty bite try to grate your own for best melting
- Salt and pepper: Season to taste always freshly cracked for pepper and fine sea salt
- Chopped parsley for garnish: Brings a burst of color and fresh flavor look for vibrant green leaves
Step-by-Step Instructions
- Prepare the Fish:
- Melt most of the butter in a large non stick skillet Once the butter foams add the tilapia fillets Lay them in gently and let them cook undisturbed for three to four minutes per side until opaque and lightly golden This quick sear locks in moisture Remove the fillets from the pan and keep them warm
- Sauté the Aromatics:
- In the same skillet add the last bit of butter and toss in the diced onion Stir often so the onion slowly releases its sugars and turns translucent and soft after about five minutes This is where much of the flavor foundation gets built
- Develop the Sauce:
- Add the chopped garlic and both the chopped and pureed roasted peppers into the onions Stir constantly for another five minutes so the peppers release their sweet flavor and the pieces get tender The kitchen will start to smell irresistible at this point
- Finish the Sauce:
- Reduce the heat Add the heavy cream and grated Parmesan cheese to the pan Stir them in gently allowing the cheese to melt into the sauce Taste for seasoning and add salt if needed Turn off the heat so the cream does not curdle
- Combine and Serve:
- Nestle the cooked tilapia fillets back into the sauce Spoon the creamy roasted pepper sauce over each fillet Top with extra parsley and Parmesan before serving for a gorgeous finish

I absolutely love the nutty salty character of real Parmesan cheese Whenever I add it over the finished dish my kids try to sneak little pinches of it before I can serve dinner The richness of the cheese takes this sauce from good to truly unforgettable and it brings everyone to the table quickly
Storage Tips
Store cooled leftovers in an airtight container in the refrigerator for up to two days The sauce may thicken upon cooling If reheating warm gently over low heat and add a splash of water or cream to loosen the sauce Be careful not to overcook the fish when reheating
Ingredient Substitutions
If you cannot find tilapia try flounder sole or even boneless skinless chicken breasts for a different spin You can substitute half and half for heavy cream in a pinch but the sauce will be slightly less rich For dairy free try using coconut milk with nutritional yeast instead of Parmesan
