Prep the salmon: Drain the canned salmon well. Remove any obvious skin and bones if you like, then flake it with a fork. If using cooked salmon, flake into small pieces.
Mix the base: In a large bowl, whisk the egg, mayonnaise, Dijon, and lemon juice until smooth.
Add seasonings: Stir in onion, parsley, garlic powder, smoked paprika, salt, and pepper.
Fold in salmon and almond flour: Add the flaked salmon and almond flour.
Gently fold until everything just comes together. The mixture should be moist but not wet. If it’s loose, add 1–2 extra tablespoons of almond flour.
Chill briefly: Cover and refrigerate for 10–15 minutes.
This helps the almond flour hydrate and the patties hold shape.
Shape the patties: Divide the mixture into 6–8 portions. With slightly damp hands, form compact patties about 3/4 inch thick.
Heat the pan: Set a large skillet over medium heat. Add 2 tablespoons oil and let it shimmer.
Pan-fry until crispy: Place patties in the skillet without crowding.
Cook 3–4 minutes per side, turning gently once, until golden brown and crisp. Add more oil as needed for the next batch.
Finish and serve: Squeeze fresh lemon over the patties. Serve hot with your favorite keto dip and a green salad or roasted veggies.
