To make the miso garlic butter sauce, melt the butter in a saucepan over medium heat. Add the sliced garlic and sauté until golden brown. Add miso and sauté for 2 minutes.
Add the white wine and bring to a boil. Simmer for 2 to 3 minutes, or until the liquid has reduced in volume by half.
For salmon: Season the salmon with salt and pepper. Heat the olive oil in a non-stick sauté pan and place the salmon skin side down and cook for 3 to 4 minutes on each side.
Transfer the salmon onto the serving plate and drizzle with the Miso Garlic Butter Sauce.
