To a food processor, combine the walnuts, flaxseed meal, garlic powder, onion powder, and dill. Pulse until well combined and walnuts are finely chopped. Alternatively, you can chop walnuts with a knife and combine ingredients together in a small bowl.
¼ cup walnuts, 2 tbsp flaxseed, 1 tsp garlic powder, 1 tsp onion powder, 1 tbsp dill
In another small bowl, whisk together the Dijon mustard, garlic, and lemon juice.
1 tbsp dijon mustard, 1 tsp garlic, 1 tbsp lemon juice
Pat the salmon dry with paper towels and brush with the mustard-lemon mixture.
Gently press the walnut mixture on top of each mustard-coated salmon fillet, making sure the top is fully covered.
6 oz salmon
Oven instructions: Preheat your oven to 375°F. To a prepared baking sheet, bake salmon for 12-15 minutes, or until salmon is cooked and flakes easily with a fork. For a crispier crust, broil the salmon for an additional 1-2 minutes at the end of cooking.
Air fryer instructions: Preheat your airfryer to 400°F and cook salmon for 10 minutes or until fully cooked.
Remove from the oven and let it rest for a few minutes. Garnish with fresh dill or parsley, and serve with a wedge of lemon on the side.
