One of my favorite parts of this dish is the slightly spicy Cajun shrimp nestled in that garlicky cream sauce My kids always try to swipe the extra sauce with their bread and it is our running joke that the pan has to be left spotless This meal brings everyone together and adds real warmth to the table

Storage Tips

Leftovers keep well in an airtight container for up to two days Reheat gently on the stove with a splash of milk to restore the sauce’s creaminess The mashed potatoes reheat best with a pat of butter stirred in

Ingredient Substitutions

You can swap the salmon for another firm fish like cod or sea bass Large scallops work beautifully in place of shrimp For a lighter sauce use half and half instead of heavy cream and low fat milk for the potatoes

Serving Suggestions

Pair this with a crisp green salad or simple steamed green beans for balance A wedge of lemon on the side adds a zesty touch The dish is perfect for holidays but impressive enough for Valentine’s Day birthday dinners or even a romantic night in
