For the Salmon:

  • 4 salmon fillets, skin-on or skinless (about 6 oz each)
  • Salt and freshly ground black pepper, to taste
  • 1 tablespoon olive oil
  • 1 tablespoon unsalted butter
  • Fresh dill or parsley, for garnish (optional)

For the Horseradish Sauce:

  • 1/2 cup sour cream or Greek yogurt
  • 2 tablespoons prepared horseradish
  • 1 tablespoon Dijon mustard
  • 1 tablespoon lemon juice
  • 1 teaspoon honey or maple syrup (optional, for sweetness)
  • Salt and freshly ground black pepper, to taste


1. Prepare the Horseradish Sauce:

  • In a small bowl, combine sour cream or Greek yogurt, prepared horseradish, Dijon mustard, lemon juice, and honey or maple syrup (if using).
  • Season with salt and freshly ground black pepper to taste.
  • Stir well to combine. Adjust the amount of horseradish to suit your preference for spiciness.

2. Cook the Salmon Fillets:

  • Pat the salmon fillets dry with paper towels. Season both sides with salt and freshly ground black pepper.
  • In a large skillet or frying pan, heat olive oil and butter over medium-high heat.
  • Place the salmon fillets in the skillet, skin-side down if they have skin. Cook for about 4-5 minutes on the first side, without moving them, until the skin is crispy and the salmon easily releases from the pan.
  • Carefully flip the salmon fillets and cook for another 3-4 minutes on the second side, or until the salmon is cooked to your desired doneness. The internal temperature should reach 145°F (63°C) for medium-rare or 160°F (71°C) for medium, using a meat thermometer inserted into the thickest part of the fillet.

3. Serve:

  • Remove the cooked salmon fillets from the skillet and transfer them to a serving platter or individual plates.
  • Spoon the horseradish sauce generously over the salmon fillets.
  • Garnish with fresh dill or parsley, if desired.
  • Serve Irish Salmon Fillets with Horseradish Sauce immediately, accompanied by steamed vegetables, roasted potatoes, or a side salad.

Tips for Success:

  • Salmon Selection: Choose fresh salmon fillets with firm flesh and a bright pink-orange color. Wild-caught salmon generally has more flavor than farm-raised salmon.
  • Horseradish Sauce Consistency: Adjust the thickness of the sauce by adding more sour cream or Greek yogurt for a creamier texture, or more horseradish for a stronger flavor.
  • Salmon Cooking Time: Be mindful not to overcook the salmon, as it can become dry. Remove it from the heat as soon as it flakes easily with a fork and is opaque throughout.
  • Garnish: Fresh herbs like dill, parsley, or chives complement the flavors of the salmon and horseradish sauce beautifully.


  • Citrus Twist: Add a squeeze of fresh lemon or lime juice to the horseradish sauce for a citrusy kick.
  • Herb Infusion: Mix finely chopped fresh herbs such as chives or tarragon into the horseradish sauce for added freshness.
  • Grilled Salmon: Instead of pan-searing, grill the salmon fillets for a smokier flavor and grill marks.
