Cooking the skin separately lets the flesh stay moist without sacrificing a crisp finish. ### Ingredients - 1½ lb wild king salmon fillet, skin removed and reserved, flesh cut into 4 portions - 1 tbsp extra-virgin olive oil - ¾ tsp Diamond Crystal kosher salt, or about half as much fine salt - ¼ tsp freshly ground black pepper ### Instructions 1. Heat the oven to 275°F. Check the salmon for pin bones and pat dry. 2. Rub the flesh with olive oil, salt, and pepper. Arrange in a shallow baking dish with space between the portions. 3. Roast until the thickest part reaches 125–130°F for moist, medium-rare to medium salmon, approximately 20–30 minutes depending on thickness. The flesh should separate into large, glossy flakes when gently pressed. 4. Rest for 3 minutes and transfer carefully with a wide spatula. ### Notes - 125–130°F is below the USDA recommendation of 145°F. Cook to 145°F for pregnant, elderly, immunocompromised, or other higher-risk diners. - Ask the fishmonger to remove the skin in broad pieces and reserve it for crisping. ## Chopped-Herb Sauce Verte Hand-chopped herbs keep the sauce lively and textured. Capers, anchovy, and vinegar cut through the richness of the salmon and beef-fat fries. ### Ingredients - 1 small shallot, finely minced - 2 tbsp red wine vinegar - 1 cup loosely packed flat-leaf parsley leaves and tender stems, finely chopped - 2 tbsp finely chopped chives - 1 tbsp finely chopped tarragon leaves - 1 tbsp drained capers, finely chopped - 2 anchovy fillets, minced to a paste - 1 small clove garlic, finely grated - ½ cup extra-virgin olive oil - to taste salt and freshly ground black pepper ### Instructions 1. Combine the shallot and vinegar in a bowl and let stand for 10 minutes to soften the shallot’s bite. 2. Stir in the parsley, chives, tarragon, capers, anchovies, garlic, and olive oil. Keep the sauce loose and spoonable rather than blending it into a purée. 3. Taste with a small piece of salmon or a plain vegetable before adding salt. Adjust with black pepper and a little more vinegar if needed. ### Notes - Stir before serving; a little separation is desirable in this oil-based sauce. - For the freshest color, chop and add the herbs within an hour of serving. ## Crisp Salmon Skin Pressing the skin between baking sheets keeps it flat while its moisture cooks away. It provides a brittle contrast to the soft salmon. ### Ingredients - 4 strips reserved salmon skin, scales removed and excess flesh scraped off - 1 tsp olive oil - 1 pinch fine sea salt ### Instructions 1. Heat the oven to 425°F. Pat the skin very dry, lightly coat with olive oil, and season with salt. 2. Lay flat on a parchment-lined metal baking sheet. Cover with another sheet of parchment and a second baking sheet to hold the skin flat. 3. Bake for 15 minutes, then lift the upper sheet carefully and check. Continue cooking for 5–10 minutes as needed, until the skin is golden and rigid. Remove the upper sheet for the last few minutes if more drying is needed. 4. Transfer to a rack and let cool uncovered. The skin should become crisp as it cools. ### Notes - Keep away from steam and sauce until the moment of serving. ## Butter-Braised Asparagus A shallow braise makes asparagus tender throughout rather than merely crisp-tender. Reducing the cooking liquid with butter creates a glossy sauce that carries the vegetable’s flavor. ### Ingredients - 1½ lb medium-to-thick asparagus - 1 tbsp ghee - ¾ cup gluten-free chicken stock or water - 2 tbsp unsalted butter, cut into pieces - 1–2 tsp fresh lemon juice - to taste salt and freshly ground black pepper ### Instructions 1. Trim the woody ends from the asparagus. Peel the lower third of especially thick stalks so they cook evenly. 2. Heat the ghee in a wide skillet over medium-high heat. Add the asparagus and cook for 3–4 minutes, turning occasionally, until lightly browned in spots. 3. Add the stock and a modest pinch of salt. Cover, reduce to medium-low, and simmer for 5–8 minutes, until a knife slides easily into the thickest stalks. 4. Uncover and let the liquid reduce to a shallow puddle, adding a splash of water if the pan dries before the asparagus is tender. 5. Lower the heat and swirl in the butter. Add lemon juice and pepper, adjust the salt, and spoon the glossy pan juices over the stalks. ### Notes - Use a wide enough pan to keep the asparagus in one or two loose layers. - Aim for tender, succulent stalks; their color will soften during the braise. ## Beef-Fat Sweet Potato Fries Rendered short-rib fat gives sweet potatoes a deeply savory edge. High heat and generous spacing brown the surfaces while leaving the centers creamy. ### Ingredients - 2 lb orange-fleshed sweet potatoes, scrubbed and left unpeeled - 3 tbsp clean rendered beef fat saved from short ribs, melted - 1 tsp Diamond Crystal kosher salt, plus more to finish - ¼ tsp freshly ground black pepper ### Instructions 1. Heat the oven to 425°F. Cut the sweet potatoes into roughly ½-inch-thick batons and dry them well. 2. Toss with the melted beef fat, salt, and pepper. Spread across two heavy metal baking sheets in a single layer with space between the pieces. 3. Roast for 20 minutes, then turn with a thin spatula and rotate the pans. Roast for another 15–25 minutes, until deeply browned at the edges and soft in the centers. 4. Season lightly with additional salt while hot. Leave uncovered so the browned surfaces do not steam. ### Notes - Use only clean rendered fat, without watery braising liquid or meat solids that could scorch. Properly frozen saved fat is suitable. - These are browned, creamy-centered oven fries rather than uniformly crunchy deep-fried potatoes. ## Overall Timing / Workflow The fries and salmon skin share the high-temperature oven first. The salmon then cooks gently while the asparagus is braised on the stovetop. ### Instructions 1. 0:00 — Heat the oven to 425°F. Prepare the sweet potatoes and salmon skin; refrigerate the salmon flesh while you work. 2. 0:15 — Start roasting the fries and crisping the skin. Use separate oven racks, rotate pans as necessary, and allow extra time if the oven is crowded. 3. 0:20 — Macerate the shallot for the sauce, chop the herbs, and trim the asparagus. 4. 0:35 — Check the skin and transfer it to a rack when crisp. Turn the fries and finish the sauce verte. 5. 0:50–1:00 — Once the fries are browned, remove them and lower the oven to 275°F. Briefly vent the oven to bring the temperature down, then add the seasoned salmon. 6. About 15 minutes before the salmon is ready — Start the asparagus. Keep the finished fries uncovered and the crisp skin dry. 7. When the salmon reaches its target temperature — Rest it briefly. If desired, give the fries 2–3 minutes under the broiler while watching closely, then plate immediately. ### Notes - Total time is approximately 80–95 minutes, depending on oven capacity and salmon thickness. ## Plating Keeping the braising juices and herb sauce away from the fries preserves their browned edges. Adding the skin last protects its crisp texture. ### Instructions 1. Place one salmon portion on each warm plate and spoon sauce verte over and around the flesh. 2. Arrange the asparagus alongside, with a little of its butter-enriched braising liquid. 3. Pile the sweet potato fries on a dry section of each plate. 4. Lay a crisp salmon-skin strip across each portion, keeping most of it above the sauce. Serve immediately. ## Leftover Path Separate storage keeps the herb sauce fresh and prevents the fries from soaking up vegetable juices. Leftover salmon is especially good served cool rather than aggressively reheated. ### Instructions 1. Refrigerate the salmon, asparagus, fries, and sauce in separate covered containers within 2 hours. Eat the salmon and vegetables within 3 days and the sauce within 2 days. 2. Serve flaked salmon cool with sauce verte and chopped leftover asparagus, or warm it gently in a covered pan with a splash of water. 3. Reheat the fries on a hot metal baking sheet at 425°F for 8–12 minutes. 4. The crisp skin is best eaten immediately. If saved, refrigerate separately and re-crisp at 375°F for a few minutes, watching closely. --- From ChezJK (https://www.chezjk.com), Jonathan Katzman's public home-cooking archive: every meal he has photographed, written up as a recipe you can cook.
