Equipment

Method
 

  1. Pat salmon dry and season with 1 tablespoon Cajun seasoning. Season shrimp with remaining Cajun seasoning and set aside.
  2. Heat olive oil in a large skillet over medium-high heat. Sear salmon for 4–5 minutes per side until golden and cooked through. Remove and keep warm.
  3. In the same skillet, add butter and minced garlic. Sauté for 30 seconds, then add shrimp. Cook 1–2 minutes per side until pink and cooked through.
  4. (Optional) Stir in heavy cream to create a light Cajun butter sauce. Simmer for 1–2 minutes and return salmon and shrimp to the pan to coat.
  5. For the mashed potatoes: Boil cubed potatoes in salted water until fork-tender (about 15 minutes). Drain and return to pot.
  6. Mash potatoes with butter, milk, and cream until smooth and fluffy. Season with salt and pepper to taste.
  7. Serve the Cajun salmon and shrimp over the creamy mashed potatoes. Spoon sauce over top and garnish with chopped parsley if desired.

Notes

For extra flavor, squeeze fresh lemon over the salmon and shrimp before serving. Add a pinch of smoked paprika or cayenne for more heat!
