How to Make Gluten Free Cajun Salmon

Preparing the Spice Blend

I start by whisking together the brown sugar, paprika, garlic powder, onion powder, cayenne, salt, and black pepper. This creates a perfectly balanced Cajun spice mix that’s flavorful without being overpowering.

Marinating the Salmon

Next, I mix orange juice, olive oil, lime juice, and 2 teaspoons of the spice blend. Pour it over the salmon and let it marinate for at least 30 minutes. This helps the salmon absorb flavor and stay moist.

Making the Mango Salsa

While the salmon marinates, I dice the mango, red pepper, and red onion. Then I toss them with chopped cilantro and lime juice. The salsa adds a sweet, tangy, and fresh crunch that complements the spiced salmon beautifully.

Cooking the Salmon

I heat 1 tablespoon of oil in a non-stick skillet, skin side up, and cook the salmon for 4–6 minutes per side until it flakes easily. If you like it blackened, I flip it back for a minute to crisp the top.

Serving the Dish

Once cooked, I serve the salmon alongside jasmine rice and spoon the mango salsa on top. A squeeze of fresh lime juice really brightens the flavors.

Additional Tips for Making This Recipe Better

I always keep the salmon skin on while cooking; it prevents drying and crisps up nicely.
Marinating the salmon longer makes it even juicier and more flavorful.
I like to toast the spices lightly in the pan before cooking to enhance their aroma.
Using fresh mango instead of canned makes a huge difference in the salsa’s sweetness.
Serve immediately for the best texture; leftovers are still great, but the skin can get soft.

How to Serve Gluten Free Cajun Salmon

I usually plate this salmon with a side of fluffy jasmine rice, mango salsa spooned over the top, and a wedge of lime on the side. Adding a handful of fresh arugula or lightly sautéed asparagus makes the dish visually stunning. Drizzling a touch of chipotle aioli over the top adds an extra layer of flavor that my guests love.

Make Ahead and Storage

Reheating: I prefer reheating gently in a skillet over medium-low heat to prevent drying. A quick microwave zap works too, just cover to retain moisture.
