Grilled Salmon Burgers with Caper Mayonnaise

These Grilled Salmon Burgers with Caper Mayonnaise are so tasty, and they’re easy to make on the grill or on a stove-top grill pan. I switched the breadcrumbs for almond flour and hemp hearts to make the salmon burgers low in carbs and gluten-free.

PIN Grilled Salmon Burgers to try them later!

I’m always up for grilling, and from early spring to late fall you’ll find me out on the deck cooking all kinds of meat, fish, and vegetables on the grill. But tasty recipes like these Grilled Salmon Burgers with Caper Mayonnaise are also easy to make on a stovetop grill pan if you don’t have an outdoor grill!

This salmon recipe is one I tried with my nephew Jake, and we gobbled ours up without a bun when we tested the recipe. Of course, they’d also be delicious served on a bun or inside low-carb pita bread with lettuce, tomato, and the caper mayonnaise spread.

But please don’t skip the delicious caper mayo that really puts these grilled salmon burgers over the top! The mayo that’s flavored with capers, lemon, pickle relish, salt and pepper literally takes minutes to make and adds so much good flavor to the salmon

What ingredients do you need for this recipe?

(This is only a list of ingredients; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

• Capers (affiliate link)
• mayonnaise
• fresh-squeezed lemon juice, I used my fresh-frozen lemon juice
• dill pickle relish (affiliate link)
• salt and pepper to taste
• celery
• onion
• chives or green onion
• Hemp Hearts (affiliate link)
• Almond Flour (affiliate link)
• egg
• Sriracha Sauce (affiliate link) (or other hot sauce of your choice)
• skinless salmon, diced into pieces
• olive oil, for brushing burgers so they won’t stick on the grill

What makes the Grilled Salmon Burgers low in carbs and gluten-free?

This recipe originally called for a cup of Panko breadcrumbs which I replaced with half Hemp Hearts (affiliate link) and half Almond Flour. That makes this recipe suitable for Keto or low-carb diets and would also make them gluten-free.

How low in carb are these Grilled Salmon Burgers?

If you eat the salmon burgers without a bun like we did, they will have less than 4 net carbs in one burger!

How can you tell when salmon burgers are done?

Use an Instant Read Meat Thermometer (affiliate link) to cook salmon burgers until they reach 145F/62C. Or if you don’t have a meat thermometer, cook the salmon burgers until they are lightly crisp on the outside and the salmon is pink and flaky inside.

Can you make Grilled Salmon Burgers without an outdoor grill?

If you don’t have an outdoor grill you could easily cook these on a Stove-Top Grill Pan (affiliate link) or even a George Foreman Grill (affiliate link) with equally good results! Remember the George Foreman Grill cooks both sides at once, so total cooking time will be much shorter.

How to make Grilled Salmon Burgers with Caper Mayo:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

1. Chop the onion, celery, and chives (or green onion) to go in the salmon.
2. Dice the salmon into small pieces so it will chop up quickly in the food processor.
3. Then pulse the Hemp Hearts (affiliate link), almond meal, onion, celery, green onion or chives, egg, hot sauce, lemon juice, salt, and pepper in the food processor until it’s well blended.
4. Add diced salmon to the food processor and pulse just a few times, until salmon is barely chopped and combined with the other ingredients.
5. Form the salmon mixture into six medium patties (or make four large patties if you prefer).
6. Chill them about 20 minutes in the freezer; this helps the patties stay together better on the grill.
7. Chop up the Capers (affiliate link); then mix the mayonnaise, lemon juice, chopped capers, pickle relish, and salt and pepper to make the caper mayonnaise. 
8. Spray the grill well with non-stick spray and preheat to medium high.
9. Just before you put the salmon on the grill, brush the surface of each burger with olive oil (or another oil of your choice).
10. Rotating the salmon burgers on the first side will give those criss-cross grill marks I like so well.
11. Serve salmon burgers hot with caper mayonnaise.

Make it a Low-Carb Meal:

Grilled Salmon Burgers with Caper Mayo would be delicious as a low-carb meal served with Garlic-Lover’s Vegetable Stir Fry, Easy Grilled Vegetables, Fattoush Lebanese Salad, Al’s Famous Hungarian Cucumber Salad, or Napa Cabbage Asian Slaw.

These Grilled Salmon Burgers with Caper Mayonnaise are so fantastic, and we replaced the breadcrumbs with almond flour and hemp hearts to make the recipe low in carbs and gluten-free!

Ingredients

Caper Mayonnaise Ingredients

• 2 T capers, drained and finely chopped
• 1/2 cup mayonnaise
• 2 T fresh-squeezed lemon juice
• 1 T dill pickle relish
• salt and pepper to taste

Salmon Burger Ingredients

• 1/2 cup celery, chopped
• 1/4 cup onion, chopped
• 1/4 cup chives or green onion, sliced (see notes)
• 1/2 cup Hemp Hearts
• 1/2 cup almond flour 
• 1 egg
• 1 T Sriracha sauce (or other hot sauce of your choice)
• 1 T fresh-squeezed lemon juice
• salt and pepper to taste
• 1 lb. skinless salmon, diced into pieces about 1/2 inch square
• olive oil, for brushing burgers so they won’t stick on the grill

Instructions

1. Drain the capers and finely chop.
2. In a small bowl or glass measuring cup, whisk together the chopped capers, mayo, light mayo, lemon juice, and dill pickle relish.
3. Taste and add salt and pepper to taste.
4. Let the caper mayonnaise chill in the fridge while you make the burgers.
5. Coarsely chop the celery, onion, and fresh chives or green onion.
6. Then add those to food processor with the hemp hearts, Almond Flour, egg, Sriracha Sauce, lemon juice, salt and pepper.
7. Pulse just until the veggies are chopped and the mixture is combined.
8. Add the diced salmon cubes and pulse a few more times until the salmon is barely chopped and mixed with the other ingredients.
9. Wash your hands, and with wet hands form the salmon into 6 medium burgers.
10. Place them on a cookie sheet as you make each one.  (We chilled them for about 20 minutes in the freezer to help the patties stay together.)
11. Spray the grill grates well with non-stick spray for the grill; then preheat grill to medium-high.  (You can only hold your hand there for 2-3 seconds at that temperature.)
12. When you’re ready to grill, use a basting brush to brush both sides of the burgers with olive or grapeseed oil.
13. Lay burgers carefully on the grill and let them cook without moving for about 4 minutes; then lift one side to see if you have good grill marks starting to show.
14. If you want criss-cross grill marks, rotate the burgers and cook 2-3 minutes more on the same side.
15. Then turn burgers carefully with a large turner and cook 2-4 minutes on the second side, or until they feel firm to the touch and are nicely browned. (For best results, use an instant-read meat thermometer and cook until burgers reach 145F/62C.)
16. Serve burgers hot with caper mayonnaise or other sauce of your choice.
17. You can serve just the salmon burger patty on a plate or on a bun with lettuce and tomato.
18. These were so good that I was excited to eat the leftover salmon burgers;  I reheated them in a dry frying pan and they were just as delicious the second day.

Notes

Use 1/2 cup green onion and skip the chives and onion if you prefer.

We replaced the whole wheat breadcrumbs with Hemp Hearts and Almond Flour to make the recipe low in carbs. Use breadcrumbs instead if you prefer and don't care about the carbs.
