  • Total Time: 20-25 minutes
  • Yield: 4 servings

Ingredients

Salmon

  • 4 (6-ounce) skin-on salmon fillets or one large 1 ¼ pound skin-on salmon fillet

Mayonnaise Mixture

  • ¼ cup olive oil mayonnaise
  • 2 tablespoons fresh dill, chopped
  • 2 tablespoons minced shallot
  • ½ teaspoon lemon zest (from 1 lemon)
  • ½ teaspoon black pepper
  • ¼ teaspoon kosher salt

Seasoning and Garnish

  • ½ teaspoon kosher salt (for seasoning salmon)
  • ½ teaspoon black pepper (for seasoning salmon)
  • Toasted breadcrumbs (optional)
  • Lemon wedges, for serving

Instructions

  1. Preheat Oven: Heat your oven to 350ºF (176ºC) and position the rack in the middle to ensure even cooking.
  2. Prepare Mayonnaise Mixture: While the oven heats, zest the lemon and cut it into wedges. In a small bowl, mix together ¼ cup olive oil mayonnaise, 2 tablespoons chopped fresh dill, 2 tablespoons minced shallot, ½ teaspoon lemon zest, ½ teaspoon black pepper, and ¼ teaspoon kosher salt until well combined.
  3. Prepare Salmon: Lightly coat a baking sheet with nonstick spray. Arrange the salmon fillets on the sheet skin-side down and pat them dry using paper towels for better seasoning adherence. Season each fillet evenly with ½ teaspoon kosher salt and ½ teaspoon pepper.
  4. Spread Mayonnaise Mixture: Evenly spread the prepared mayonnaise mixture over the top of the salmon fillets to infuse them with flavor and moisture during baking.
  5. Roast Salmon: Place the baking sheet in the preheated oven and roast salmon until it flakes easily with a fork and reaches an internal temperature of 125ºF in the center. This takes about 15 to 20 minutes for standard fillets, or 7 to 10 minutes for thin, wild-caught fillets.
  6. Add Toppings and Serve: If using, sprinkle toasted breadcrumbs on top for a crunchy texture. Serve immediately with fresh lemon wedges on the side to squeeze over the salmon for added brightness.

Notes

  • Using skin-on salmon helps keep the fillets moist during baking and makes handling easier.
  • Adjust baking time if you are using thinner or thicker fillets to avoid overcooking.
  • Toasted breadcrumbs add a nice texture contrast, but you can omit them if you prefer a softer topping.
  • Fresh dill can be substituted with dried dill if fresh is not available, but reduce the amount to 1 teaspoon.
  • Use a meat thermometer to ensure perfect doneness and avoid dry salmon.
