Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Start by patting the salmon fillets dry with paper towels. This step is important to help the seasoning stick and create a proper crust.
In a small bowl, mix together paprika, garlic powder, onion powder, thyme, oregano, cayenne pepper, black pepper, and salt. This will form your Cajun spice blend.
Rub the seasoning mixture evenly over both sides of the salmon fillets, pressing gently so it adheres well.
Heat a heavy skillet, preferably cast iron, over medium-high heat. Add olive oil and let it get hot but not smoking.
Place the salmon fillets in the pan, skin-side down if the skin is on. Cook for about 4–5 minutes without moving them, allowing a dark crust to form.
Carefully flip the salmon and add the butter to the pan. As the butter melts, spoon it over the salmon repeatedly to keep it moist and flavorful.
Cook for another 3–4 minutes until the salmon is cooked through and flakes easily with a fork.
Finish with a light drizzle of lemon juice and remove from heat. Serve immediately.

Variations
You can adjust the spice level by reducing or increasing the cayenne pepper. For a milder version, use smoked paprika and skip the cayenne altogether.
If you prefer a slightly sweeter flavor, add a pinch of brown sugar to the spice mix.
For a citrus twist, use lime juice instead of lemon.
You can also bake the salmon instead of pan-searing. Place it in a preheated oven at 200°C and cook for about 12–15 minutes.
For extra richness, add a garlic butter sauce with minced garlic and a squeeze of fresh lemon.
Storage/Reheating
Store any leftover salmon in an airtight container in the refrigerator for up to 2 days.
To reheat, place the salmon in a skillet over low heat with a small amount of butter or oil. Cover and warm gently to avoid drying it out.
You can also reheat it in the oven at a low temperature (around 150°C) for about 10 minutes.
Avoid microwaving if possible, as it can make the fish rubbery.
