A keto dinner that earns the butter.

Prep the asparagus, garlic, capers and dill before heating the pan. The written method moves from searing the salmon to cooking the vegetables, then finishing the sauce over lower heat.

Fillet thickness and pan space affect timing. Use a thermometer for doneness and cook in batches when scaling up. Treat the times below as starting estimates while this recipe awaits kitchen testing.

One pan / five moves

The method

Read once before the pan gets hot, then use each 10-second visual cue beside the written step. From the first sizzle onward, the recipe moves quickly. For 4 or 6 servings, use a larger skillet or cook in batches, allowing extra time. The ingredient selector scales quantities; divide them using the proportions in each step.

  1. Dry hard. Season simply.

    5 minutes

    Pat the salmon dry on every side, especially the skin. Season with two thirds of the measured salt and all the pepper. Toss the asparagus with half the olive oil and the remaining salt.

    AI visual cue / step 01
  2. Build the crust.

    7 minutes

    Heat a heavy skillet over medium-high. Add the remaining oil, then place the salmon skin-side down. Press each fillet for 20 seconds so the skin stays flat. Cook, undisturbed, until the skin is deeply crisp and the salmon is mostly opaque up the sides.

    AI visual cue / step 02
  3. Flip once. Blister the greens.

    5 minutes

    Flip the salmon and move it to one side. Add the asparagus and lemon halves, cut-side down. Cook until the asparagus is bright and blistered and the salmon reaches 145°F at its thickest point. Transfer the salmon and asparagus to a warm plate.

    AI visual cue / step 03
  4. Make the pan butter.

    3 minutes

    Lower the heat. Add the butter, garlic, and capers. Swirl until foamy and fragrant, about 45 seconds. Squeeze in half of the charred lemon pieces, remove the pan from the heat, and stir in the dill.

    AI visual cue / step 04
  5. Sauce, then serve.

    1 minute

    Plate the salmon skin-side up so it stays crisp. Spoon the lemon-dill butter around and partly over the fish. Serve immediately with the asparagus and remaining charred lemon.
