Mince garlic and chop onion.
Heat up a nonstick skillet over medium heat. Place salmon fillets in the skillet and season generously with salt and pepper. Cook for 4-5 minutes on each side or until golden brown. Remove from skillet and set aside. Leave about 1 tsp of the rendered salmon oil in the skillet and discard the rest.
Add garlic and onion and cook over medium heat for 5 minutes.
Add red curry paste and cook for 3 minutes, stirring constantly.
Reduce the heat to low and add coconut milk. Let mixture come to a simmer, then add salmon fillets back to skillet.
Cover and let simmer gently for 10 minutes or until salmon is cooked to your liking.
Garnish with cilantro and serve with lime wedges. Enjoy!
