Gather all ingredients before starting the recipe.
Pre heat oven to 375°F.
Season salmon on both sides and set aside until ready to cook.
Cut bok choy into 2" pieces and set aside until ready to use.
Combine coconut milk, ginger, garlic, curry paste in a medium sauce pan over medium high heat. Stir to combine and season with kosher salt. Bring to a boil, then reduce to a simmer and cook for 6-8 minutes.
Pour coconut milk mixture into a deep casserole and place the bok choy in the sauce.
Nestle salmon onto bok choy and cover the baking dish with aluminum foil. Place in a pre heated oven for 15-20 minutes.
Check the salmon after 15 minutes, and if flakes easily, remove from oven and uncover.
Garnish salmon with sliced scallions, cilantro and cashews and serve with plain white basmati rice.
