A baked potato slathered with butter is great, but add hot-smoked fish, scallions and dill to that butter, and you get a potato that’s smoky, onion-y and fresh. The first step of the recipe will produce baked potatoes with chip-like skin and dried-out interior thirsty for that creamy addition. The recipe makes about 1 1/2 cups of fish butter, so you also can enjoy it on toast, hot rice or pasta, steamed vegetables, jammy eggs and so on.

Active time: 15 mins; Total time: 1 hour 10 min

Storage Notes: Refrigerate the fish butter for up to 7 days

Tested size: 4 servings

  • 4 large russet potatoes (2 pounds total), scrubbed
  • 1 tablespoon extra-virgin olive oil
  • Fine salt
  • 1 stick (8 tablespoons) unsalted butter, softened
  • 1 cup flaked, skin-off hot-smoked trout or salmon (from about 5 ounces fillets)
  • 1/4 cup finely chopped fresh dill, plus more for serving
  • 3 scallions, thinly sliced, plus more for serving
  • Freshly ground black pepper


Position a rack in the middle of the oven and another one directly below, and preheat to 400 degrees.

Poke holes all over the potatoes with a fork. In a medium bowl, toss the potatoes with the oil and a pinch of salt. Place the potatoes directly on the oven rack, and set a large, rimmed baking sheet on the rack below to catch any drips; reserve the bowl. Roast for 1 hour or until the potatoes offer no resistance when a sharp paring knife is inserted into their centers.

Meanwhile, transfer the butter to the reserved bowl and use a spoon or fork to mash it. Add the fish, dill and scallions, and mash and stir to combine. Season to taste with pepper; the fish is quite salty, so you probably won’t need additional salt. You should have about 1 1/2 cups of fish butter.

When the potato is tender but still hot, carefully make an incision lengthwise, then push the ends in to crack it open. Using a fork, fluff the steamy interior, then add 1 to 2 tablespoons of the fish butter and mix to combine. Garnish with an additional bit of the butter, the dill and scallions and serve right away.
