This meal consists of salmon fillets seasoned with a Cajun spice blend and seared in a skillet. The fish is served with a sauce made from heavy cream, cream cheese, Parmesan, and garlic. Fresh spinach is added to the sauce and the dish is finished with lemon wedges and chopped parsley.

About This Recipe

The preparation begins by coating the salmon fillets with Cajun seasoning and placing them in a hot skillet with olive oil or butter. The fish is cooked on both sides and then moved to a separate plate. Minced garlic is added to the remaining fat in the pan, followed by heavy cream, cream cheese, and grated Parmesan. These ingredients are stirred over medium heat until the cheeses melt and the liquid bubbles.

Fresh or drained spinach is placed into the pan with the cream mixture. The spinach is stirred until the leaves wilt and the liquid in the pan reduces. The seared salmon fillets are put back into the skillet on top of the spinach and sauce. The sauce is spooned over the fish while the pan remains on the heat for a short period. Lemon wedges are sliced and placed on the plate at the time of assembly.

The salmon can be replaced with chicken or shrimp, and the spinach can be substituted with kale or Swiss chard. The fish and the sauce are stored in the refrigerator if not eaten immediately. The final dish is assembled by placing the salmon fillets on top of the creamed spinach and adding chopped parsley to the surface.
