How to Make Baked Cajun Salmon
-
Preheat Oven: Start by setting your oven to 400°F (200°C) to get it ready for the salmon. This temperature ensures a beautifully cooked dish with that lovely crisp outside.
-
Prepare Baking Sheet: Line a baking sheet with parchment paper. This helps in easy cleanup later and prevents the salmon from sticking.
-
Mix Cajun Rub: In a small bowl, combine olive oil, Cajun seasoning, salt, and pepper. Stir well until mixed, creating a flavorful paste that will coat the salmon perfectly.
-
Season Salmon: Place your salmon fillets on the prepared baking sheet, and brush both sides generously with the Cajun mixture. Coat them until they look vibrant and ready for baking!
-
Bake Salmon: Transfer the baking sheet to the preheated oven and bake for about 15-20 minutes. The salmon should flake easily with a fork when done, showcasing a lovely golden hue.
-
Make Avocado Lime Sauce: While the salmon bakes, mash the avocado in a bowl. Mix in lime juice, Greek yogurt, minced garlic, salt, and pepper, whisking until smooth and creamy.
-
Serve: Once the salmon is beautifully cooked, drizzle the creamy Avocado Lime Sauce over the fillets. For an extra touch, garnish with fresh cilantro if desired.

You can store leftover Baked Cajun Salmon in an airtight container in the fridge for up to 2 days. To make sure it retains moisture, reheat it gently in a low oven at 350°F (175°C) for about 8 minutes, or use an air fryer for a quicker option that keeps it juicy.

How can I adjust the spice level of the Cajun seasoning?
The spice levels in your Cajun seasoning are very adjustable! If you prefer a milder flavor, you can reduce the amount of seasoning used or opt for a mild Cajun blend. Alternatively, if you’re looking for more heat, feel free to add a pinch of cayenne pepper or incorporate diced jalapeños into the mix!
