The Stars of the Show: Key Ingredients

The magic of this dish lies in its simple yet powerful ingredients. You’ll need a good quality salmon fillet and a handful of spices that you likely already have in your pantry.

For the Salmon

  • Salmon Fillets: Look for 4 center-cut salmon fillets, about 6 ounces each. Skin-on or skinless both work wonderfully for this recipe.
  • Olive Oil: A little olive oil helps the seasonings adhere to the fish and promotes a beautiful crust.

For the Homemade Cajun Seasoning

While you can use a store-bought blend, making your own allows you to control the flavor and sodium levels. Simply mix these together:

  • Smoked Paprika: Provides a deep, smoky color and flavor.
  • Garlic Powder: For a savory, aromatic base.
  • Onion Powder: Adds a subtle sweetness and depth.
  • Dried Thyme: Brings an earthy, slightly minty note.
  • Cayenne Pepper: This is where the heat comes from! Adjust the amount to your preferred spice level.
  • Salt & Black Pepper: To enhance all the other flavors.

How to Make Baked Cajun Salmon (Step-by-Step)

Making this spicy salmon is as simple as season and bake. Follow these steps for perfect results.

  1. Preheat and Prepare: First, preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup. Pat the salmon fillets completely dry with a paper towel—this is crucial for getting a nice crust.
  2. Season the Salmon: In a small bowl, whisk together the smoked paprika, garlic powder, onion powder, thyme, cayenne, salt, and pepper. Brush the salmon fillets lightly with olive oil. Then, sprinkle the Cajun seasoning generously over the top of each fillet, pressing gently to help it adhere.
  3. Bake to Perfection: Place the seasoned salmon fillets on the prepared baking sheet. Bake for 12-15 minutes. The exact time will depend on the thickness of your fillets. The salmon is done when it flakes easily with a fork.
  4. Serve Immediately: Serve the Baked Cajun Salmon hot, straight from the oven, with a squeeze of fresh lemon juice to brighten the flavors.

Pro-Tips for Perfect, Flaky Salmon Every Time

  • Don’t Overbake: This is the most important tip! Salmon cooks quickly. Keep a close eye on it and check for doneness at the 12-minute mark. Overcooked salmon will be dry.
  • Dry the Fish: Patting the salmon fillets dry with a paper towel before seasoning is a non-negotiable step. A dry surface allows the seasoning to stick better and helps the exterior to form a slight crust.
  • Even Thickness: If possible, use salmon fillets that are similar in thickness to ensure they all cook at the same rate.

Delicious Serving Suggestions

This Baked Cajun Salmon is incredibly versatile. For a complete and satisfying meal, pair it with a side that complements its bold flavors. We love serving it with healthy sautéed vegetables for a low-carb option. It’s also fantastic with a scoop of creamy garlic parmesan orzo (coming soon) or alongside some crispy roasted cauliflower. For a heartier meal, try it with a simple green salad or fluffy quinoa.

Storing and Reheating Your Salmon

Store any leftover salmon in an airtight container in the refrigerator for up to 3 days. To reheat, it’s best to warm it gently in the oven at 300°F (150°C) for about 10 minutes or until warmed through. You can also flake the cold salmon and add it to salads or wraps for a delicious lunch, like this chicken bacon ranch wrap but with salmon!
