Ingredients
- 4 (6-ounce) skin-on salmon fillets, 3/4- to 1-inch thick, preferably wild-caught, thawed if frozen (see Chef’s Note)
- 1 tablespoon kosher salt
- 1 tablespoon extra-virgin olive oil
- 1 lemon
- 1 cup (260 grams) whole milk yogurt (not Greek-style)
- 1/2 cup (23 grams) chopped fresh dill fronds
- 2 teaspoons stone-ground mustard
- 1 teaspoon prepared horseradish
- 3 grinds black pepper
- 2 tablespoons neutral oil, such as safflower or canola
Instructions
- Place the salmon on a wire rack set in a rimmed baking sheet. Rub the fillets with 2 teaspoons of the salt, then refrigerate for 45 minutes. Meanwhile, set your immersion circulator bath for 124 degrees F (51 degrees C).
- Pat the salmon dry with paper towels, then divide between two gallon-size vacuum-seal or high-quality freezer zip-top bags. Add 1 1/2 teaspoons of the olive oil to each bag, then gently rub the fish to coat. Use a peeler to harvest eight strips of lemon peel and place two strips, pith-side up, on top of each fillet. Halve and juice the lemon; set the juice aside to use in the sauce. If using vacuum-seal bags, use the “gentle” or “moist” setting to seal the bags.
- Transfer the fillet bags to the water bath. If using zip-top bags, let the salmon sink, forcing the air out of the bag via displacement. Right before the mouth of the bag goes into the water, seal the bag. Leave the salmon to cook for 45 minutes. (If one of the bags floats, carefully reopen and try the sink-and-seal method again.)
- While the salmon cooks, make the sauce: In a medium bowl, combine the yogurt, dill, mustard, horseradish, and pepper. Stir in the remaining teaspoon of salt and 1 tablespoon of the lemon juice. Stir well, then season to taste with additional salt, pepper, and lemon juice, if desired. Set aside until ready to serve.
- When the salmon is finished, remove it from the water bath. Open the bags and very carefully remove the fish to a paper towel-lined sheet pan. Pat the fish as dry as possible with additional paper towels. Brush the skin side lightly with some of the neutral oil.
- Heat a 10-inch cast-iron skillet over high heat for 3 minutes. Add 2 teaspoons of the neutral oil and swirl the pan to coat. When the oil starts to smoke, add two of the salmon fillets, skin-side down. Brush the flesh side lightly with additional oil. Cook until the skin is browned and crisp, about 1 minute. Carefully flip with a narrow metal spatula or “fish turner” and cook on the second side just until just brown, about 30 seconds. Carefully transfer to a serving platter and repeat with the remaining oil and fillets. Serve with the dill-yogurt sauce.

Reviews
Great recipe. I did add a little mayo which helps add a bit of richness and make it taste less like simply seasoned yogurt. It also makes for a very nice dressing served with the salmon over greens.
Dill yogurt sauce is great. I use with many of my fish recipes now.
