Cut the salmon into 1-inch pieces and season with lemon zest, salt, and pepper. In a mixing bowl, gently toss to coat.
Heat the olive oil in a large skillet over medium-high heat.
Add the salmon pieces to the skillet and cook for 3 minutes without stirring. Stir and cook for 1 minute more.
Move the salmon to the side and add the butter to the empty side of the skillet. Once melted, add the garlic and cook until fragrant. Gently stir the garlic butter into the salmon.
Immediately transfer to a serving bowl and garnish with parsley. Serve with lemon wedges if desired.
Notes
Do not overcook the salmon.
Make sure to add the minced garlic as soon as the butter is melted.
Keep a close eye and make sure the butter and garlic don’t brown or burn.
