Lebanese Spicy Lingcod with Walnut–Cilantro Topping, Tahina Eggplant, and Ras al Hanout Sweet Potato Fries

Roasted Lingcod

A short roast keeps lean lingcod moist while leaving its mild flavor available to the assertive walnut-and-herb topping.

Ingredients

  • 1.5 lb skinless lingcod fillet, cut into 4 portions of similar thickness
  • 1 tbsp extra-virgin olive oil
  • 0.75 tsp kosher salt, plus more to taste
  • 0.25 tsp freshly ground black pepper
  • 1 lemon, cut into thin half-moons or wedges for serving

Instructions

  1. Heat the oven to 425°F. Pat the fish dry and check carefully for pin bones.
  2. Lightly oil a shallow baking dish. Arrange the fish with space between the portions, rub with the remaining olive oil, and season with salt and pepper.
  3. Roast for 10–15 minutes, depending on thickness, until the center reaches 145°F and separates into moist flakes. Begin checking thin portions at 8 minutes.
  4. Transfer to plates and spoon the warm walnut–cilantro topping generously over the fish. Finish with lemon.

Notes

  • Fold a very thin tail end underneath itself so it cooks at a similar rate to the thicker portions.

Spicy Onion, Cilantro, and Walnut Topping

Soft onion carries the chile and garlic, while walnuts give the cooked cilantro mixture substance and a little texture. Lemon keeps the rich, olive-oil-laced topping lively.

Ingredients

  • 0.5 cup walnut halves
  • 0.25 cup extra-virgin olive oil
  • 1 large yellow onion, finely chopped
  • 4 garlic cloves, finely chopped
  • 2 cups chopped cilantro leaves and tender stems, loosely packed
  • 1 tsp silk chile flakes
  • 0.5 tsp black Urfa chile, plus more to taste
  • 2 tbsp fresh lemon juice
  • 2 tbsp water, plus more as needed
  • 0.5 tsp kosher salt, plus more to taste
  • 0.25 cup fresh cilantro leaves, reserved for finishing

Instructions

  1. Toast the walnuts on a small tray in the 425°F oven for 4–6 minutes, checking frequently, until fragrant. Cool slightly and chop finely, leaving some small pieces for texture.
  2. Warm the olive oil in a skillet over medium-low heat. Add the onion and salt and gently sweat for 12–15 minutes, stirring occasionally, until very soft and translucent rather than crisp or deeply browned.
  3. Add the garlic, silk chile, and Urfa chile. Stir for 1 minute, then add the chopped cilantro and cook for 2–3 minutes until wilted and aromatic.
  4. Stir in the walnuts, lemon juice, and water. Cook gently for 2 minutes to bring everything together; the mixture should be moist and spoonable, with some olive oil visible around the edges.
  5. Taste for salt, lemon, and heat. Keep warm over very low heat, adding a splash of water if it tightens. Scatter the reserved fresh cilantro over the topped fish.

Notes

  • Chile blends vary in salt and heat; taste before adding extra salt or increasing the chile.

Roasted Eggplant

Roasting cut-side down produces browned flesh and a creamy interior without needing to fry the eggplant.

Ingredients

  • 2 medium globe eggplants, about 1.5–2 lb total
  • 3 tbsp extra-virgin olive oil
  • 0.75 tsp kosher salt
  • 0.25 tsp freshly ground black pepper
  • 0.25 cup flat-leaf parsley leaves

Instructions

  1. Heat the oven to 425°F. Halve the eggplants lengthwise and lightly score the flesh in a crosshatch without cutting through the skin.
  2. Rub the flesh and skin with olive oil and season with salt and pepper. Place cut-side down on a parchment-lined sheet pan.
  3. Roast for 30–40 minutes, until the skin is slightly collapsed and the flesh yields easily to a spoon. Turn cut-side up for the last 5 minutes if excess moisture needs to evaporate.
  4. Let stand for 5 minutes, then spoon lemon-garlic tahina over the warm flesh and finish with parsley.

Notes

  • Eggplant is ready when the center is completely soft, not merely browned on the surface.

Lemon-Garlic Tahina

Lemon and garlic sharpen the sesame richness, while cold water turns tahini into a light, creamy sauce that clings to the eggplant.

Ingredients

  • 0.33 cup well-stirred tahini
  • 2 tbsp fresh lemon juice
  • 1 small garlic clove, finely grated
  • 0.25 tsp kosher salt
  • 3–5 tbsp cold water

Instructions

  1. Whisk the tahini, lemon juice, garlic, and salt together. It will initially become thick and stiff.
  2. Whisk in cold water a tablespoon at a time until pale, smooth, and thickly pourable.
  3. Taste and adjust the salt or lemon. Let stand for 5 minutes, then loosen with a little more water if necessary.

Notes

  • Aim for a sauce that falls from a spoon in a broad ribbon rather than a thin stream.

Ras al Hanout Sweet Potato Fries

Thick wedges develop browned edges while staying tender inside. Ras al hanout gives their sweetness a savory, warmly spiced counterpoint.

Ingredients

  • 1.5 lb orange-fleshed sweet potatoes, scrubbed
  • 2 tbsp olive oil
  • 2 tsp gluten-free ras al hanout spice blend without added sugar
  • 0.75 tsp kosher salt, reduced if the spice blend contains salt

Instructions

  1. Heat the oven to 425°F. Cut the sweet potatoes into long wedges about 1/2–3/4 inch thick at their widest point.
  2. Dry well, then toss with olive oil, ras al hanout, and salt.
  3. Spread in a single layer on a large metal sheet pan, leaving space between the wedges. Use a second pan if necessary rather than crowding.
  4. Roast for 30–40 minutes, turning after 20 minutes, until browned at the edges and tender inside. Check during the final 10 minutes so the spices and narrow tips do not burn.
  5. Taste and add a small pinch of salt if needed. Serve promptly.

Notes

  • These are roasted wedges with caramelized edges, not uniformly crisp deep-fried fries.

Overall Timing / Workflow

The vegetables share one oven temperature, and the topping and tahina can be prepared while they roast. Cooking the fish last keeps it moist and ready to serve.

Instructions

  1. 0:00 — Heat the oven to 425°F. Prepare the eggplant and sweet potato wedges and set them on separate sheet pans.
  2. 0:15 — Put both vegetables in the oven on upper- and lower-middle racks. Toast the walnuts briefly alongside them, then start the onion topping on the stovetop.
  3. 0:25 — Make the tahina, chop the finishing herbs, and portion and season the fish.
  4. 0:35 — Turn the sweet potatoes and rotate the vegetable pans between racks. Finish the walnut–cilantro topping and keep it warm.
  5. 0:45–0:55 — Remove the vegetables as they become tender and browned. Hold loosely covered; leave the sweet potatoes uncovered to preserve their edges.
  6. Roast the fish for 10–15 minutes. If needed, return the sweet potatoes to the oven for the final 3 minutes, then plate everything immediately.

Notes

  • Allow roughly 65–75 minutes total, including preparation; oven capacity and eggplant size affect the schedule.

Plating

Keeping the three main elements distinct preserves the sweet potatoes' browned edges and lets the two rich sauces serve different parts of the plate.

Instructions

  1. Set a portion of lingcod on one side of each warm plate. Cover generously with the onion, cilantro, and walnut topping, including a little of its olive oil.
  2. Add a lemon half-moon or wedge and a few fresh cilantro leaves to the fish.
  3. Place an eggplant half alongside, spoon tahina over its cut surface, and scatter with parsley.
  4. Pile the sweet potato wedges in the remaining space, keeping them out of the sauces until eating.

Leftover Path

Separate storage protects the vegetables' texture and allows the fish to be warmed gently rather than overcooked.

Instructions

  1. Refrigerate leftovers within 2 hours in separate airtight containers. Eat the fish within 2 days and the vegetables and sauces within 3–4 days.
  2. Reheat sweet potatoes on a sheet pan at 400°F for 8–12 minutes. Warm the eggplant separately until hot, then add tahina after reheating.
  3. Warm the fish and its topping in a covered baking dish at 275°F with a small splash of water, checking frequently; bring reheated leftovers to 165°F.
  4. For a cold next-day lunch, flake the fish over chopped leftover eggplant, add the walnut topping, and finish with lemon. Serve the sweet potato wedges alongside.

Notes

  • Tahina thickens in the refrigerator; whisk in a little cold water before serving.
