How to Prepare Blackened Cajun Salmon Fillets
Now, let’s get into the nitty-gritty of making these mouthwatering blackened Cajun salmon fillets! Follow these steps, and I promise you’ll be amazed at how easy and delicious it is.
Step 1: Prepare the Salmon
First things first, you’ll want to pat those salmon fillets dry with paper towels. This step is crucial because it helps the seasoning stick to the fish, giving you that beautiful crust when it cooks. Plus, excess moisture can prevent that lovely sear you’re after. So, take your time here!
Step 2: Season the Fillets
Next up, let’s get those fillets dressed! Generously sprinkle the Cajun seasoning over both sides of each salmon fillet. Don’t be shy—really press the seasoning into the fish. This step ensures every bite is packed with flavor! You can adjust the amount based on your spice preference; if you like it hot, go for it!
Step 3: Heat the Skillet
Now, grab your trusty cast iron skillet and heat it over medium-high heat. Add the olive oil and butter, watching closely as the butter melts and starts to sizzle. You want it to be hot but not smoking—this is when you know your skillet is ready for action! The right temperature is key for that perfect blackened crust.
Step 4: Cook the Salmon
Carefully place the salmon fillets skin-side up in the hot skillet. Don’t move them around; let them cook for about 4-5 minutes. You’ll see a gorgeous dark crust forming. Once that’s done, flip the fillets and cook for another 4-5 minutes, or until the salmon flakes easily with a fork. Keep an eye on the thickness of your fillets, as cooking times may vary!
Step 5: Serve
Voila! Your blackened Cajun salmon fillets are ready to shine. Remove them from the skillet and serve immediately with lemon wedges for that zesty kick. I love pairing these fillets with a side of rice, steamed veggies, or a fresh salad. Trust me, it’s a meal that’ll wow everyone at the table!

Tips for Success
To ensure your blackened Cajun salmon fillets turn out perfectly every time, here are some pro tips that I’ve picked up along the way:
- Preheat Your Skillet: Always make sure your cast iron skillet is properly heated before adding the salmon. A hot skillet helps create that sought-after blackened crust. If the butter starts to brown but not smoke, you’re in the sweet spot!
- Don’t Rush the Seasoning: Give the Cajun seasoning time to stick to the fish. Press it in gently but firmly—this way, you’ll get a flavorful crust that won’t fall off during cooking.
- Watch the Time: Keep an eye on your cooking times, especially if your fillets are varying in thickness. Thicker fillets may need a minute or two more, while thinner ones will cook faster. Trust your instincts here!
- Let It Rest: After cooking, let the salmon rest for a minute before serving. This allows the juices to redistribute, making each bite tender and juicy.
- Adjusting Spice Levels: If you’re unsure about spice levels, start with less Cajun seasoning and taste as you go. You can always add more, but it’s tricky to dial it back once it’s on!
These tips will help you achieve the best results, ensuring your blackened Cajun salmon fillets are a hit every time you serve them! Happy cooking!

Storage & Reheating Instructions
After you’ve enjoyed your delicious blackened Cajun salmon fillets, you might find yourself with some tasty leftovers. No worries, I’ve got you covered on how to store and reheat them so they stay just as flavorful as when they were first cooked!
Storing Leftovers
To keep your salmon fresh, let it cool down to room temperature first. Then, wrap each fillet tightly in plastic wrap or place them in an airtight container. This helps prevent any air from getting in and keeps the salmon moist. You can safely store your blackened Cajun salmon fillets in the refrigerator for up to three days. If you want to keep them longer, consider freezing them! Just make sure to wrap them well in freezer-safe packaging to avoid freezer burn.
Reheating Tips
When it’s time to enjoy those leftovers, reheating them properly is key to maintaining that juicy flavor and texture. Here’s how to do it:
- Skillet Method: This is my favorite way! Heat a small amount of olive oil in a skillet over medium-low heat. Once it’s warm, add your salmon fillets and cover the skillet. Heat for about 3-4 minutes, gently flipping halfway through. This method keeps the salmon tender and helps retain that delicious crust.
- Oven Method: Preheat your oven to 350°F (175°C). Place the salmon on a baking sheet lined with parchment paper, and cover it loosely with foil to retain moisture. Bake for about 10-12 minutes or until warmed through. This method is great for reheating multiple fillets at once!
- Microwave Method: If you’re in a rush, the microwave will do! Place the salmon on a microwave-safe plate and cover it with a damp paper towel. Heat on medium power for about 30-60 seconds, checking frequently to avoid overcooking. It may not retain that crispy crust, but it’ll still be delicious!
And there you have it! With these storage and reheating tips, you can enjoy your blackened Cajun salmon fillets even after the initial meal. Trust me, they’ll taste just as good the second time around! Happy eating!
