I’m definitely a Joey Tribbiani in my love of sandwiches, and my husband will grill anything and everything in the summer. Needless to say, we eat a lot of grilled sandwiches.

And you know me, I’m always looking for new salmon recipes. From salmon pasta to pineapple salmon, we eat this versatile fish at least once a week.

This grilled salmon sandwich has been one of my favorite meals lately. With a simple combination of fresh salmon, an herby mayo sauce, a fluffy bun and some leafy lettuce, it’s simple to prepare and satisfying to eat.

If you don’t have a grill, don’t worry about it – the salmon can be cooked on a grill pan (just like my Sonoran hot dogs) or in the oven.

What you’ll need to make this salmon sandwich recipe:

  • salmon – you’ll need 1-1/2 pounds of skinless salmon fillets. More on how to choose the perfect fish below.
  • oil – I like a neutral oil like canola oil or vegetable oil for grilling fish.
  • hamburger buns – my favorite for salmon sandwiches are brioche buns!
  • lettuce – I like fresh, crunchy butter lettuce best.
  • salt and pepper – for seasoning the salmon and also the mayo.
  • mayonnaise – this will be the base of our herb mayo sauce.
  • fresh basil leaves – the main flavor component of the herb mayo. Any extra basil can be used to make homemade pesto for pesto salmon.
  • dill – fresh dill is best, but I know it’s annoying to buy fresh for such a small amount. Extra fresh dill can be used for Greek chicken meatballs, but dried is also good substitute. If using dried dill, use half the amount called for.
  • lemon juice – this adds a bit of tang to the herb mayo, and can also be squeezed over the fish for extra flavor.
  • garlic – to add a savory note to the herb mayo for this grilled salmon sandwich.
  • Dijon mustard – this adds a little kick of heat (but not TOO much) to the herb mayo.

The herb mayo can be made in advance!

While the herb mayo takes only about 5 minutes to make, I see all you meal preppers out there. The people who want to prepare as much as possible in advance so that weeknight meals are a breeze. I got you.

One way to make sure that this salmon sandwich recipe comes together as fast as humanely possible is to make the herb mayo in advance.

So, go ahead and make this herb mayo up to 2 days in advance. Just keep it in an airtight container in the fridge until you’re ready to serve the salmon sandwiches. This same herb may can also be used for smoked salmon BLTs.

How to buy the best fish for grilled salmon sandwiches:

Just like with stuffed salmon and salmon piccata, I prefer thicker, center-cut pieces of salmon, and not thinner, tail-end pieces for this salmon sandwich recipe.

The tail end pieces or larger fillets are really better for a recipe where the salmon is going to be flaked, like salmon cakes with fresh salmon or Cajun salmon pasta.

If you have a grocery store, butcher, or seafood market where you can specify that you need center-cut pieces, that’s ideal for salmon sandwiches. I prefer skinless salmon fillets for this recipe.

You can use any variety of salmon you like best for this salmon sandwich recipe, whether that’s Atlantic salmon, sockeye salmon, or something else. Food & Wine’s Guide to Every Type of Salmon You Can Buy will help you learn the differences.

How to cook salmon on the grill:

Making grilled salmon doesn’t have to be scary. But I admit, I was intimidated the first time I tried it, and I even went to culinary school! It just SEEMS like it’s going to stick to the grill, right?

Don’t worry, I’m here to walk you through how to cook salmon on the grill for a salmon sandwich successfully every time. Just like with my grilled chicken pizza, there are two keys to grilled salmon: a clean grill and oil.

Let’s start with the clean grill. If you don’t have a wire grill brush, run to the hardware store right now and get one. The salmon will wait until you get back.

Really scrub that grill to get off ALL the crumbs and crusty bits, because those bits are what the fish will stick to. Fish will NOT stick to clean grill grates as much.

Then, we need oil. You’ll be using canola oil to throughly oil both sides of the salmon filletsYou will ALSO be spraying those clean grill grates with nonstick cooking spray to add another layer of nonstick protection.

Preheat your grill to medium-high and don’t spray the grill grates until JUST before you place the fish on the grill.

Place the salmon directly on the clean, oiled grill grates. Cover the grill and cook 4 to 5 minutes or until the fish is beginning to turn opaque.

Quickly and confidently flip the fish with a heatproof fish spatula. Once the fish is flipped, cover the grill again and cook 4 to 5 minutes longer.

If you have an instant read thermometer, the easiest way to check for doneness is to check for an internal temperature of 125 degrees F in the thickest part of the fish. Having a thermometer is the easiest way to determine how long to cook salmon on the grill.

Allow the salmon to rest for 5 minutes before building the sandwiches, and the fish will be perfectly cooked. Follow the same instructions above if using a grill pan, too.

How to bake salmon for a salmon sandwich:

If you don’t have a grill and would rather bake the salmon for salmon sandwiches, you’re in luck: baking salmon is basically the easiest thing in the world, and I use this same technique for my salmon alfredo and bourbon glazed salmon, too.

For this salmon sandwich recipe, first, preheat the oven to 400 degrees F.

Then, grab a small rimmed baking pan. I usually line it with foil for super easy cleanup. Spray the foil with nonstick cooking spray (or rub it lightly with oil) so the salmon doesn’t stick.

Place the salmon on the foil and give it a sprinkling of salt and pepper.

Bake at 400 degrees F for 16 to 18 minutes or until the fish is cooked through.

What to serve with a salmon sandwich:

My favorite summer side dishes are spicy potato chips, Dr. Pepper baked beans and elote salad. Or, if you want to get fancy, try my summer beet salad recipe. Any combination of these sides are the perfect way to round out the meal.

More delicious salmon recipes:

In my opinion, salmon is just as versatile as chicken. At breakfast, lunch or dinner, it’s a great choice for lean protein.
