Trout Almondine with Roasted Arrowhead Cabbage, Delicata Squash and Sunchokes
Crisp-skinned trout gets a generous spoonful of toasted almonds, lemon-brown butter and parsley. Sweet, char-edged arrowhead cabbage and deeply roasted delicata squash and sunchokes make this a late-autumn plate with plenty of texture and enough acidity to balance the butter.

Crisp-Skinned Trout
Dry skin and steady contact with the pan create a crisp surface while keeping the delicate flesh moist. Most of the cooking happens skin-side down.
Ingredients
- 4 skin-on trout fillets, 6–8 oz each, scaled and pin bones removed
- 2 tbsp ghee
- 3/4 tsp fine sea salt, or to taste
- 1/4 tsp freshly ground black pepper
Instructions
- Pat the trout thoroughly dry, especially the skin. Keep refrigerated uncovered while preparing the vegetables, then season just before cooking.
- Heat a large heavy skillet over medium-high heat. Add half the ghee and, once shimmering, lay in two fillets skin-side down. Press gently with a fish spatula for 20–30 seconds to prevent curling.
- Reduce the heat to medium and cook for 4–6 minutes, until the skin is crisp, releases readily and the flesh is opaque most of the way up the sides.
- Turn and cook on the flesh side for 30 seconds to 2 minutes, depending on thickness. For fully cooked trout, check for 145°F in the thickest part; remove promptly to avoid drying it out.
- Transfer skin-side up to warm plates. Repeat with the remaining ghee and trout, adjusting the heat if the pan begins smoking.
Notes
- Use two skillets if available so all four portions finish together. Do not cover cooked fish, which softens the skin.
Lemon-Brown Butter Almondine Sauce
Toasted almonds echo the browned butter while lemon and parsley keep the sauce bright. Adding the lemon off heat stops the browning before the milk solids scorch.
Ingredients
- 6 tbsp unsalted butter
- 2/3 cup sliced almonds
- 1 small shallot, finely minced
- 2 tbsp fresh lemon juice, plus more to taste
- 1 tbsp water
- 1/3 cup chopped flat-leaf parsley
- to taste fine sea salt and freshly ground black pepper
Instructions
- Melt the butter in a small, light-colored skillet over medium heat. Add the almonds and cook, stirring frequently, for 3–4 minutes until they begin to turn pale gold.
- Add the shallot and continue cooking for 2–3 minutes, stirring and lowering the heat as needed, until the almonds are golden, the shallot is softened and the butter solids smell nutty and look hazelnut brown.
- Remove from the heat. Carefully stir in the lemon juice and water; the butter will sputter.
- Stir in the parsley just before serving. Season with salt and pepper, taste for acidity and spoon over the trout immediately.
Notes
- If preparing ahead, stop after browning and transfer to a cool saucepan. Rewarm gently, then add the lemon, water and parsley just before serving.
- The sauce should be spoonable rather than thick. Add another teaspoon or two of water if needed.
Roasted Arrowhead Cabbage
Keeping the core attached holds the wedges together while the cut faces caramelize. High heat browns the outer leaves without cooking all the texture out of the center.
Ingredients
- 1 large head arrowhead cabbage, about 2 lb
- 2 tbsp extra-virgin olive oil
- 1/2 tsp fine sea salt
- 1/4 tsp freshly ground black pepper
- 2 tsp fresh lemon juice
- 2 tbsp chopped flat-leaf parsley
Instructions
- Heat the oven to 425°F with racks in the upper and lower thirds. Remove any damaged cabbage leaves and cut the head lengthwise into four wedges, keeping a section of core in each.
- Rub the wedges with olive oil, working a little between the outer leaves. Season with salt and pepper and arrange on a rimmed baking sheet with one cut side down.
- Roast for 18–20 minutes. Turn onto the other cut side and roast for another 12–20 minutes, until the edges are deeply browned and a knife enters the thick base with slight resistance.
- Finish with lemon juice and parsley just before serving.
Notes
- If the outer leaves darken before the core is tender, loosely shield the wedges with foil for the final few minutes.
Roasted Delicata Squash and Sunchokes
Thin delicata crescents become sweet and tender while chunky sunchokes develop crisp edges and creamy centers. Giving the sunchokes a head start brings both vegetables to doneness together.
Ingredients
- 1 medium delicata squash, about 1 lb
- 1 lb sunchokes
- 2 1/2 tbsp extra-virgin olive oil, divided
- 3/4 tsp fine sea salt, divided
- 1/4 tsp freshly ground black pepper
- 2 tsp fresh lemon juice
- 2 tbsp chopped flat-leaf parsley
Instructions
- Scrub the sunchokes well and dry thoroughly; leave the skins on. Cut into roughly 3/4-inch chunks, halving small ones.
- Halve the delicata lengthwise, scoop out the seeds and cut crosswise into 1/2-inch crescents; leave the skin on.
- Toss the sunchokes with 1 1/2 tablespoons olive oil and 1/2 teaspoon salt. Spread on a large rimmed baking sheet and roast at 425°F for 10 minutes.
- Toss the delicata with the remaining oil and salt and the black pepper. Add to the sheet, turn the sunchokes and spread everything into a single layer.
- Roast for another 25–35 minutes, turning once, until the squash is browned and tender and the sunchokes are deeply golden with creamy centers. Rotate the sheet and exchange oven racks with the cabbage partway through for even browning.
- Toss gently with the lemon juice and parsley, then taste for seasoning.
Notes
- Use a second sheet if necessary rather than crowding the vegetables; crowded sunchokes steam instead of browning.
Overall Timing / Workflow
Roast the vegetables first and finish the fish and sauce at the last moment. The vegetables tolerate a short wait, while crisp trout skin does not.
Instructions
- 0:00 — Heat the oven to 425°F. Dry and refrigerate the trout, then scrub and cut the vegetables.
- 0:15 — Put the sunchokes in the oven. Prepare the cabbage wedges and sauce ingredients.
- 0:25 — Add the delicata to the sunchokes and put the cabbage on the other oven rack.
- 0:40 — Turn the vegetables and rotate the trays. Make the almond-brown butter mixture, then take it off the heat before adding the lemon and parsley.
- 0:50 — Check the vegetables for tenderness and browning. Begin cooking the trout when the vegetables are nearly ready; allow extra time if using one skillet in batches.
- 1:00–1:10 — Finish the sauce with lemon, water and parsley. Season the roasted vegetables with their lemon and herbs, plate and serve immediately.
Notes
- Total elapsed time is approximately 60–70 minutes, depending on fillet thickness and the size of the cabbage.
Plating
Keeping the three elements distinct preserves their textures and shows off the browned vegetables. Last-second saucing leaves more of the trout skin crisp.
Instructions
- Place a cabbage wedge along one side of each warm plate.
- Arrange a portion of delicata and sunchokes beside it, keeping the browned surfaces visible.
- Set the trout skin-side up in the remaining space. Spoon the warm almondine sauce generously across the fish just before serving, leaving some skin exposed.
- Distribute any parsley remaining in the vegetable bowls over the plates and serve immediately.
Leftover Path
Storing the fish, vegetables and sauce separately prevents sogginess and lets each be reheated appropriately.
Instructions
- Refrigerate leftovers in separate airtight containers within 2 hours. Eat the trout and sauce within 2 days and the vegetables within 3–4 days.
- Reheat the vegetables at 400°F for 10–15 minutes, until hot and crisp at the edges.
- For the best fish texture, flake the trout cold over a salad with the roasted vegetables. Alternatively, reheat gently in a 275°F oven, loosely covered, until it reaches 165°F; the skin will soften.
- Warm the almondine sauce over low heat with a splash of water, stirring gently. Add fresh lemon or parsley to brighten it before serving.
