Step 1

Gather all the ingredients.

Step 2

Pat down any juice on salmon with a paper towel and sprinkle salt and pepper evenly on both sides of the fillet. Cut into 2 vertical slices about 1 inch width and set aside.

Step 3

Place butter in a small mixing bowl and melt in microwave (about 20-30 seconds but this will vary on your microwave).

Step 4

Grind garlic with a grinder or garlic press and place into melted butter along with Soy Sauce and Yuzu. Mix well and set aside.

Step 5

Cut green onions into thin slices and set aside.

Step 6

Add oil into cast iron pan and place on high heat. Once the oil starts to lightly smoke, reduce heat to medium-high and carefully place salmon fillets into cast iron pan skin down (please note oil will splatter so take precautions). Cover and cook for 2-2.5 minutes (1.5-2 minutes for skinless). Note - when searing, don't move the meat.

Step 7

After searing one side, carefully flip the salmon to the other side, cover and cook for an additional 1-2 minutes. Carefully transfer salmon to a serving plate when done. Note - the salmon will be very fragile so make sure to support the bottom.

Step 8

Lightly drizzle garlic butter sauce and sprinkle chopped green onion over salmon.
