Combine mayonnaise and shoyu in a small bowl. Set it aside.
Line the salmon fillets onto a towel and pat them dry to remove moisture.
Set the oven to a low broil and line a rimmed sheet pan with parchment paper or a silicon mat. Arrange the fillets onto it and generously coat the top of the salmon with the mayonnaise mixture. Then, sprinkle furikake seasoning over the tops.
Broil uncovered for 10-12 minutes until the salmon reaches an internal temperature of 125°F (51°C). Then, sprinkle with more furikake seasoning for a little extra flavor.
Notes
Expert Tips:
Pat dry the salmon fillets before coating them with shoyu mayo. The excess moisture causes the fish to steam rather than broil.
If using skin-on salmon, cook the salmon skin side down so you can coat the tops with the delicious mayonnaise, and the skin will crisp perfectly against the parchment paper.
Overcooked salmon can be dry and tough, so keep a close eye on it as it cooks. Use a food thermometer to check the internal temperature of the salmon. It is the best way to ensure you don't overcook the fish. The recommended cooking temperature for salmon is 125°F (51°C).
