This pellet grill salmon is weeknight cooking at its best — just 4 ingredients, under 30 minutes from grill startup to plate, and consistently one of the most requested meals at our table. The combination of Cajun seasoning and a sweet heat BBQ rub gives the grilled salmon bold, layered flavor without any fuss.
Most guys who own a pellet grill use it for one thing: long, low-and-slow cooks. Briskets that run 12 hours overnight. Smoked pork shoulder that goes all day. And that’s great — there’s nothing better than a properly smoked brisket with a thick bark. But here’s the thing: your pellet grill is also one of the fastest, most foolproof tools you have for a weeknight dinner, and salmon is the perfect proof of that.
This pellet grill salmon recipe comes together in under 30 minutes from startup to plate — including the time it takes for the grill to heat up. It’s become a weekly staple at our house. The kids love it, cleanup is easy, and you’re cooking outside, which is always a win. If you’ve never put salmon on your pellet grill before, this is the recipe that’s going to change that.

Ingredients
- Salmon fillets — center-cut fillets are ideal (about 6 oz each). Center-cut gives you an even thickness so every piece cooks at the same rate.
- Cajun seasoning — a store-bought blend works great. Right now I’m loving the Cajun Two Step Seasoning by StaleKracker.
- BBQ seasoning / rub — use your go-to rub. Our sweet hickory blend with brown sugar, black pepper, and chili notes works especially well on salmon. Get our ‘Que That Barbecue Seasoning here.
- Spray oil — for the skin side and a light coat on the flesh before it goes on the grill.
Optional: Fresh orange or lemon slices for serving. Oranges pair especially well with salmon — give it a try before defaulting to lemon.
Ingredient Notes
- Center-cut fillets cost about a dollar more per pound than other cuts, but they’re worth it for weeknight cooking. The uniform thickness means all your pieces come off the grill at the same time — no guessing, no babysitting one thin end that’s already overcooked while the thick part catches up.
- If you want to make your own salmon seasoning instead of store-bought, a homemade Cajun-style blend with paprika, garlic powder, onion powder, cayenne, and black pepper works great and gives you full control over the heat level. Or you can also try our homemade salmon seasoning (with a secret ingredient that you wouldn’t expect!).
Easy Pellet Grill Salmon
Ingredients
- 4 center-cut salmon fillets, about 6-7 oz each
- 1 tablespoon Cajun seasoning, adjust to taste
- 1 tablespoon 'Que That Barbecue Seasoning, or your favorite sweet-style BBQ rub
- Spray oil, for skin and grill grates
Instructions
- Prep the grill. Preheat the pellet grill to 350°F with your choice of pellets.
- Prep the salmon. While the grill heats up, check for pin bones by running your fingers along each fillet and remove any you find. Oil the skin side of each fillet with spray oil. No need to season this side unless you plan to eat the skin. Then season the flesh side with Cajun seasoning first, then with BBQ seasoning on top. Let the seasoning set for a few minutes while the grill finishes coming up to temperature.
- Grill the salmon. Spray the grill grates lightly with oil, then place the salmon skin side down. Close the lid and cook for approximately 14-16 minutes. Do not flip.
- Check for doneness. Check doneness with a meat thermometer. Pull at 130–135°F for medium. *The FDA recommends 145°F for fully cooked fish, but most salmon lovers prefer it pulled a bit earlier.
- Plate and serve. When salmon is done cooking, carefully remove from the grill with a spatula or fish turner. Plate and serve.

Notes
- Cook time will vary based on fillet thickness. Always use a thermometer — time is just a guideline.
- Center-cut fillets ensure even cooking across all pieces. Worth the extra dollar per pound on a weeknight.
- The Cajun seasoning I used in this recipe is Cajun Two Step by Stale Kracker. One of my favorite Cajun seasonings lately.
How to Make Pellet Grill Salmon
Step 1: Fire Up the Grill
Set your pellet grill to 350°F and let it come up to temperature. While it’s heating, you’ve got just enough time to prep your salmon — so no time is wasted.
*For the pellets, I love Smokin’ Pecan pellets. They’re my absolute favorite wood pellets for my Traeger, and I use them for most proteins that I grill.
Step 2: Prep the Salmon
Run your fingers along each fillet and remove any pin bones you find. Flip the fillets skin side up and spray or brush with oil — you’re not seasoning the skin side unless you plan to eat it. Oiling the skin just helps prevent it from sticking to the grill grates.
Flip them back over and apply your Cajun seasoning first, going a little lighter than you think you need. Follow that up with your BBQ rub on top. The combination of the two creates that sweet heat flavor that works so well on salmon.
Let the seasoned fillets sit for a few minutes while the grill finishes heating. You’ll see the seasoning start to sweat into the fish — that’s exactly what you want.
Step 3: Grill the Salmon
Give the grill grates a light spray of oil, then place the salmon skin side down. Close the lid and let it cook for approximately 13-15 minutes. Don’t flip — salmon cooks beautifully skin side down the entire time, and you’ll get a lightly crispy skin on the bottom.
Step 4: Check for Doneness and Serve
Pull the salmon when it hits your preferred internal temperature. Use a meat thermometer and check the thickest part of the fillet.
For a medium cook — moist, flaky, and slightly translucent in the center — pull your salmon at about 130-135°F. The FDA recommends 145°F for fully cooked fish, but most salmon lovers prefer it pulled a bit earlier, and in fact, most chefs cook salmon to about 130-135°F internal.
*This is where a good instant read meat thermometer comes in handy. This is the one that I use and love!
Plate it up and finish with a squeeze of fresh orange — it cuts through the richness of the fish and brightens everything up.
Recipe Tips for Perfect Pellet Grill Salmon
- 350°F is the sweet spot. It gives you good cook speed without drying out the fillet. The edges will get slightly crispy, which adds great texture.
- Don’t skip the oil on the grates. Even if you’ve oiled the skin, a light spray on the grates helps with the lift when you’re plating.
- Cook time varies. About 13 minutes is typical, but the real guide is internal temperature — not the clock. Every grill runs a little different.
- Don’t overcook it. Salmon goes from perfect to dry fast. Pull it early rather than late — it will continue to carry over cook slightly after you remove it from the grill.
Frequently Asked Questions
350°F works great for a weeknight cook. It’s hot enough to get some texture on the edges without drying out the center. If you prefer a slower, smokier result, you can drop to 275–300°F, but plan for a longer cook time.
No. Place the fillets skin side down and leave them. The skin acts as a natural barrier and protects the fish while it cooks. Flipping increases the risk of the fillet breaking apart. The top will cook through from the ambient heat in the grill.
Plenty. Hot honey glazed, bourbon maple, maple sweet chili for an Asian-inspired spin, or orange marmalade are all great alternatives. Once you’ve mastered the basic method, the seasoning options are wide open.
