In a large bowl, combine the drained salmon, breadcrumbs, chopped onion, and parsley.
Add the beaten egg, Dijon mustard, garlic powder, salt, and pepper to the mixture.
Mix everything well until fully combined.
Shape the mixture into 4 equal patties.
Heat olive oil in a skillet over medium heat.
Once hot, add the patties to the skillet, leaving space in between.
Cook for 4-5 minutes on each side, or until golden brown.
Remove the patties from the skillet and place them on paper towels to drain excess oil.
Serve warm with lemon wedges or your favorite sauce.
Enjoy your homemade salmon patties!
