Open the canned salmon and drain any excess liquid.
Flake the salmon with a fork, removing bones and skin if desired.
In a large bowl, combine the flaked salmon, breadcrumbs, and eggs.
Add finely chopped onions and seasonings (salt, pepper, and any desired herbs).
Add mayonnaise for moisture.
Stir gently until all ingredients are well-combined, but avoid overmixing.
Take a small handful of the salmon mixture and shape it into a patty.
Place the patties on a plate or tray lined with parchment paper.
Heat a skillet over medium heat with oil or butter.
Carefully place the patties in the hot skillet.
Fry for 3-4 minutes per side, or until golden brown and crispy.
Remove the cooked patties from the skillet and place them on a paper towel-lined plate to drain excess oil.
Serve hot, garnished as desired.
If using vegetables, add them to the bowl after the salmon is flaked
If adding cheese, add it to the mixture before forming patties
If using any heat, add spices before mixing.
If making gluten-free, swap out ingredients before mixing.
