Ingredients

Instructions

  1. Step 1: Pat dry 4 salmon fillets and evenly rub 2 tbsp Cajun seasoning all over the flesh sides. Let rest at room temperature for 10 minutes.
  2. Step 2: In a medium bowl, combine 1 diced ripe mango, 1/2 diced red bell pepper, 1/4 cup finely chopped red onion, 2 tbsp chopped cilantro, 2 tbsp lime juice, 1/2 tsp salt, 1/4 tsp black pepper, and 1/2 minced jalapeño (optional). Toss gently and set aside to let flavors meld.
  3. Step 3: Heat 2 tbsp olive oil in a large nonstick skillet over medium-high heat until shimmering. Place salmon fillets skin-side down and cook for 4 minutes until edges are crispy.
  4. Step 4: Carefully flip the salmon and cook for an additional 3-4 minutes until cooked through and the Cajun crust is dark and flavorful.
  5. Step 5: Serve each salmon fillet topped with a generous spoonful of mango salsa for a vibrant contrast.

Transfer to an airtight jar and refrigerate for up to 5–7 days. Most sauces freeze well for up to 2 months — portion into small containers or freezer bags so you can thaw only what you need. Stir before serving; cream- or yogurt-based sauces may separate on standing.
