This particular grilled salmon recipe with cajun seasoning is one from my childhood. This is the way my parents always cook their salmon and It converted me at a young age.

I added some fresh lemon and herbs to make it extra special, but you can also use lemon pepper if you’ve got it!

This recipe is the perfect mix of flavors with the lemon and thyme, along with Cajun spices. The foil packet method ensures the salmon stays moist and tender, while making clean-up super convenient. It’s an easy-to-make recipe, ideal for a quick weeknight dinner or a delicious meal during a barbecue.

How to Cook Grilled Salmon in Foil

Step 1: Start with a wild-caught, fresh salmon fillet.

Pre-frozen fillets would work, too, but the best flavor comes from fresh fillets.

I always get wild-caught salmon at Costco in a two-pack and cook both of them at the same time so I can make salmon cakes with the leftovers.

Step 2: Gather herbs & spices

Cajun seasoning is so good on salmon. I don’t know why, but it is.

It’s pretty easy to find a good, clean blend at the grocery store. (I like Spicely’s and Morton & Bassett’s blends.)

You can also make your own! I included a recipe for homemade Cajun seasoning in my cookbook, but I’m sure a Google search would give you lots of options.

Fresh thyme, garlic, and lemon slices are delicious on salmon and compliment Cajun seasoning really well!

Step 3: Prepare Salmon in Foil

Lay the fillet on a large piece of aluminum foil.

Smear the fillet with the spices and garlic and arrange the lemon and thyme on top! Oh, and don’t forget the butter or ghee. It makes a big difference!

(I nearly forgot — it didn’t make it into the photo. Oops.)

Just put several small blobs along the fillet — this is really scientific, isn’t it?

Crip the edges and then throw that puppy on your hot grill.

Or in a really hot oven — like 425 degrees.

What to serve with grilled salmon

If you’re looking for side dishes or salads to go with this, here are a few ideas…

A big, homemade Caesar salad is my favorite thing to serve with this salmon. It’s one of our go-to summertime meals! My Whole30 Caesar Dressing is a great option if you’re needing a dairy-free creamy dressing.

This Easy Cajun Sausage & Rice Skillet would compliment this salmon beautifully!

Southwest Cabbage Slaw or Sweet Kale Salad are a couple of other tasty options, too!

Salmon on the Grill (in Foil)

Yield: Serves 4-6

Prep Time: 10 minutes

Cook Time: 10 minutes

Total Time: 20 minutes

Hands down, this is my all-time favorite way to cook salmon -- my parents cooked it this way when I was growing up. The foil packet creates a steamy environment and you end up with tender, juicy, flavorful salmon that you can't stop eating.

Ingredients

1 whole, fresh salmon fillet (or 4-6 smaller fillets)
Sea salt
Black pepper
1 teaspoon Cajun seasoning
2 cloves of garlic, minced
2 lemons, one sliced into rounds, one sliced into wedges
3-4 sprigs of fresh thyme
2-3 Tablespoons ghee or grass-fed butter

Instructions

Preheat your grill to high heat.
Cut a piece of aluminum foil twice as long as the salmon fillet. Place the foil on a rimmed baking sheet so half is on the baking sheet and the other half extends to the side. Place the salmon on the side of the foil that is over the baking sheet.
Sprinkle the fillet liberally with sea salt and black pepper. Add the Cajun seasoning and garlic and rub them around evenly on the fillet. Place the lemon slices and thyme springs on top, and put blobs of ghee/butter on the fillet as well.
Fold the foil over to cover the salmon and crimp the sides to form a packet.
Place the packet on the grill. Cover the grill and cook for 8-12 minutes, until the thickest parts of the salmon are just barely cooked through -- or even slightly dark pink still.
Remove the salmon, turn off the grill, and let it cool for a few minutes before serving. Serve with lemon wedges.
