What You’ll Need: The Ingredients

Here are the ingredients that bring this amazing dish to life. Using fresh components will always give you the best results.

4 salmon fillets (about 6 ounces each) – Look for vibrant, pink fillets that are firm to the touch.
1 tablespoon olive oil – This helps the seasonings stick and prevents the salmon from drying out on the grill.
2 teaspoons Cajun seasoning – You can use your favorite store-bought brand or make a homemade blend for custom heat.
Salt and pepper to taste – Essential for enhancing all the other flavors.
Lemon wedges for serving – A fresh squeeze of citrus at the end brightens the entire dish.

Optional Marinade:

1 tablespoon Dijon mustard – Adds a tangy depth that pairs wonderfully with the spices.
1 tablespoon honey – Provides a touch of sweetness to balance the heat.
1 tablespoon fresh lemon juice – Its acidity helps to tenderize the fish.
1 teaspoon minced garlic – For an extra layer of aromatic flavor.

Note: This recipe is designed for 4 servings.

Cooking Time

Prep Time: 10 minutes (or 40 minutes if marinating)
Cooking Time: 10-14 minutes
Total Time: 20-24 minutes

Equipment You Need

Grill: A gas or charcoal grill is necessary for that signature smoky flavor.
Grill Spatula: A wide spatula makes flipping the delicate salmon fillets much easier.
Paper Towels: Use these to pat the salmon dry, which is key for a good sear.
Small Bowl: For mixing the marinade ingredients if you choose to use it.
Pastry Brush: To evenly apply the olive oil or marinade onto the salmon.

How to Make Cajun Grilled Salmon Recipe

This recipe is straightforward, but following these steps will help you achieve a perfect result. From prepping the fish to the final flip on the grill, each stage is simple and quick.

Step 1: Prepare the Salmon

First, take your salmon fillets out and pat them completely dry with a paper towel. This step is crucial because removing excess moisture helps the skin get crispy and allows the surface to sear nicely. Once dry, brush each fillet on all sides with olive oil.

Step 2: Season Generously

Now it’s time for the flavor. Sprinkle the Cajun seasoning, salt, and pepper evenly over both sides of the salmon fillets. Don’t be shy with the seasoning; you want a nice, flavorful crust to form when it hits the heat of the grill.

Step 3: Marinate for Extra Flavor (Optional)

If you have some extra time, I highly recommend the marinade. In a small bowl, whisk together the Dijon mustard, honey, fresh lemon juice, and minced garlic. Coat the salmon fillets in this mixture and let them marinate in the refrigerator for at least 30 minutes.

Step 4: Get the Grill Ready

Preheat your grill to a medium-high heat, around 400-450°F. If you’re using a charcoal grill, wait until the coals are covered in a light gray ash. For a gas grill, simply close the lid and let it heat up for about 10-15 minutes. Clean the grates and oil them well to prevent the salmon from sticking.

Step 5: Grill the Salmon

Place the salmon fillets on the hot grill, skin-side down. The skin will protect the delicate flesh from the direct heat. Close the lid and let them cook for about 6 to 8 minutes. You’ll see the color change from the bottom up as it cooks.

Step 6: Flip and Finish Cooking

Using a wide spatula, carefully flip the salmon fillets. Cook for another 4 to 6 minutes on the other side. The salmon is done when it flakes easily with a fork or when an instant-read thermometer inserted into the thickest part reads 145°F.

Additional Tips for Making This Recipe Better

After making this recipe many times, I’ve picked up a few tricks to make it even more delicious.

I always make sure not to overcook the salmon. It can go from perfect to dry in just a minute, so keep a close watch on it.
I prefer using fresh, not frozen, salmon for this recipe. The texture and flavor are noticeably better.
If you like things extra spicy, I suggest adding a pinch of cayenne pepper to your Cajun seasoning blend. It gives it a great kick.
Letting the salmon rest for a couple of minutes after taking it off the grill makes a huge difference. It stays much juicier.

Variations to Try

This recipe is fantastic as is, but it’s also easy to adapt to your preferences or dietary needs.

Herb-Infused: Add fresh herbs like thyme or dill to the seasoning mix for a brighter, more complex flavor.
Smokier Flavor: Add a pinch of smoked paprika to the Cajun seasoning to enhance the smoky taste from the grill.
Other Fish: This Cajun seasoning works beautifully on other firm fish like mahi-mahi, swordfish, or even shrimp.
