Use paper towels to thoroughly dry each salmon fillet to ensure seasoning adheres properly and promotes a good sear.
02 -
Generously season the salmon with kosher salt and black pepper. If skinless, season both sides; if skin-on, season only the flesh side.
03 -
Place seasoned salmon fillets into vacuum seal bags or heavy-duty zip-top bags. Drizzle each fillet with 1/2 tablespoon olive oil, top with lemon slices, add a sprig of dill under each fillet, and sprinkle minced garlic as desired. Add butter pats for extra richness if using.
04 -
If using a vacuum sealer, seal according to device instructions. For zip-top bags, slowly submerge in water to expel air via pressure and finally seal completely, creating a near-vacuum environment.
05 -
Attach immersion circulator to a large container filled with water. Set temperature based on preference: 120°F for medium-rare, 130°F for medium, and 140°F for medium-well salmon. Allow water to reach set temperature.
06 -
Submerge sealed salmon bags fully in the water bath. Weigh down if needed. Cook for 30 to 45 minutes depending on fillet thickness; thinner fillets require less time.
07 -
Heat a cast iron or heavy skillet over medium-high heat and add 1 tablespoon olive oil. Ensure pan is hot before adding salmon.
08 -
Take salmon from bags, discard lemon slices and dill sprigs. Pat each fillet completely dry with paper towels to maximize searing performance.
09 -
Place fillets skin-side down if skin is on, and sear for 2 to 3 minutes until skin is crispy and golden. For skinless fillets, sear 1 to 2 minutes per side until browned. Avoid overcrowding the pan.

During the last minute of searing, add butter to skillet and spoon melted butter over salmon to enhance flavor and texture.

Transfer salmon to plates, garnish with fresh dill or lemon wedges as desired, and serve promptly for optimal flavor and texture.
