Ingredients

For the Salmon:

  • 2 teaspoons Cajun or Creole seasoning for that signature spice
  • 1/2 teaspoon smoked paprika adds a smoky flavor
  • 1 tablespoon olive oil for pan-searing the salmon
  • 1 tablespoon butter adds richness to the sauce
  • 1/2 cup finely diced onion sweet and aromatic base
  • 1/2 cup finely diced red bell pepper for color and sweetness
  • 2 cloves garlic minced, a must for flavor
  • 3/4 cup chicken broth use a low-sodium option
  • 3/4 cup heavy cream for that creamy texture
  • 1/2 teaspoon crushed red pepper flakes for an extra kick
  • 1/2 teaspoon black pepper for seasoning
  • 1/4 teaspoon Cajun or Creole seasoning to season the sauce
  • 1 to 2 teaspoons cornstarch optional, for thickening the sauce
  • 2 teaspoons lemon juice freshly squeezed for brightness
  • 1/2 cup freshly grated Parmesan cheese the star of the sauce
  • 2 green onions sliced for garnish and fresh flavor
  • 1 tablespoon chopped fresh parsley adds color and freshness

Instructions

Instructions

  • Start by patting your salmon fillets dry with paper towels. This helps them sear nicely. Season both sides generously with Cajun seasoning and smoked paprika.
  • In a large skillet, heat the olive oil over medium-high heat. Once hot, add the salmon, skin side down if applicable. Sear for about 4-5 minutes on each side until golden brown and cooked through. Remove the salmon from the skillet and set aside on a plate.
  • In the same skillet, melt the butter. Add the finely diced onion and red bell pepper. Sauté for about 3-4 minutes, or until the vegetables are soft. Add the minced garlic and cook for another minute until fragrant.
  • Pour in the chicken broth, scraping up any browned bits from the bottom of the skillet. Allow it to simmer for a couple of minutes before adding in the heavy cream, crushed red pepper flakes, black pepper, and additional Cajun seasoning. Stir well to combine.
  • If you prefer a thicker sauce, mix the cornstarch with a little water to create a slurry and add it to the sauce while stirring continuously. Bring it to a gentle simmer until it thickens.
  • Remove the skillet from heat and stir in the freshly grated Parmesan cheese and lemon juice until melted and combined.
  • Return the salmon to the skillet, spooning the creamy sauce over the top. Let it warm through for a minute, then garnish with sliced green onions and chopped parsley.
