Baked Salmon with Mayonnaise
1 tsp. canola oil
8 2" × 3" skin-on boneless salmon filets (about 2 lbs.)
1 tbsp. plus 2 tsp. soy sauce
3⁄4 cup mayonnaise
1. Grease an 8" × 8" baking dish with the oil. Rub the salmon filets with 1 tbsp. of the soy sauce, then arrange them snugly in the prepared dish, skin side up. Rub the salmon skin with the remaining soy sauce; cover dish with plastic wrap and refrigerate for 30 minutes.
2. Heat oven to 425°. Remove baking dish from refrigerator and set aside to let come to room temperature for 15 minutes. Spread the mayonnaise evenly over the salmon, spreading it out to the edges of the baking dish. Bake, rotating once, until skin is golden brown and salmon is cooked through, about 20-25 minutes. Remove the salmon from the oven and set aside to let rest for 5 minutes before serving.
