True Cod with Caper-Mustard Butter, Spicy Cauliflower, and Roasted Sunchokes

Gently Roasted True Cod

Moderate roasting preserves cod's large, tender flakes without creating a heavy crust that would compete with the sauce.

Ingredients

• 4 portions true cod fillet, 6–7 ounces each, preferably evenly thick
• 1 tablespoon olive oil
• 1/2 teaspoon kosher salt, plus more to taste
• 1/4 teaspoon freshly ground black pepper

Instructions

1. Heat the oven to 425°F. Pat the cod dry, season with salt and pepper, and let stand for 10 minutes while preparing a shallow baking dish.
2. Coat the dish with the olive oil and arrange the fish with space between the portions. Fold any thin tail ends underneath to make the thickness more even.
3. Roast for 12–18 minutes, checking early for thinner pieces. The thickest part should reach 145°F and separate into moist flakes with gentle pressure.
4. Transfer carefully to warm plates and spoon over the warm caper-mustard butter immediately.

Notes

• Cod is delicate once cooked; use a wide fish spatula and avoid moving it repeatedly.

Lemon Caper-Mustard Butter

Dijon helps bind butter and cooking liquid into a light sauce, while capers and lemon cut the richness and season the mild fish.

Ingredients

• 3 tablespoons water
• 2 tablespoons drained capers, rinsed if very salty
• 2 teaspoons gluten-free Dijon mustard
• 1 tablespoon fresh lemon juice, plus more to taste
• 5 tablespoons cold unsalted butter, cubed
• 2 tablespoons finely chopped flat-leaf parsley
• to taste kosher salt and freshly ground black pepper

Instructions

1. In a small saucepan, simmer the water and capers for 1 minute. Reduce the heat to low and whisk in the mustard and lemon juice.
2. Add the cold butter a few cubes at a time, whisking continuously and lifting the pan off the heat as needed. Keep the sauce warm but below a simmer until glossy and lightly thickened.
3. Stir in the parsley. Taste before adding salt, then adjust the lemon and pepper.
4. If too thick, whisk in warm water a teaspoon at a time. Spoon over the fish just before serving.

Notes

• Do not boil after adding the butter. If the sauce separates, whisk it gradually into a teaspoon of cool water in a clean pan over very low heat.

Spicy Roasted Cauliflower with Olives and Herbs

Large florets develop dark, nutty edges while retaining some bite. Chile, briny accents, and fresh herbs keep the roasted cauliflower lively rather than heavy.

Ingredients

• 1 large head cauliflower, about 2 pounds, cut into 1 1/2–2-inch florets
• 3 tablespoons olive oil
• 1/2 teaspoon red chile flakes, or to taste
• 1/2 teaspoon kosher salt, plus more to taste
• 1 clove garlic, finely grated
• 1/3 cup pitted green olives, halved
• 1 tablespoon drained capers
• 2 scallions, thinly sliced
• 1/4 cup roughly chopped flat-leaf parsley
• 1 tablespoon fresh lemon juice

Instructions

1. Heat the oven to 425°F. Toss the cauliflower with 2 tablespoons of the olive oil, the chile flakes, and salt. Spread on a large sheet pan with flat cut surfaces against the metal.
2. Roast for 25 minutes, then turn the florets. Continue roasting for 5–15 minutes, until deeply browned at the edges and just tender through the stems.
3. Mix the remaining tablespoon of olive oil with the garlic. Toss with the hot cauliflower, olives, and capers, then return to the oven for 2 minutes to mellow the garlic.
4. Transfer to a bowl and fold in the scallions, parsley, and lemon juice. Taste and adjust the salt and chile.

Notes

• Use a second pan if necessary; crowded cauliflower steams instead of browning.

Roasted Sunchokes

Roasting skin-on chunks on a hot metal pan caramelizes the cut faces while leaving the centers creamy and earthy.

Ingredients

• 1 1/2 pounds sunchokes
• 2 tablespoons olive oil
• 1/2 teaspoon kosher salt
• 1/4 teaspoon freshly ground black pepper

Instructions

1. Heat the oven to 425°F. Scrub the sunchokes thoroughly, trim damaged areas, and dry well; leave the skins on.
2. Cut into roughly 1-inch chunks, halving small ones and quartering larger ones. Toss with the olive oil, salt, and pepper.
3. Spread on a metal sheet pan in one layer, with a cut face down. Roast for 20–25 minutes without disturbing.
4. Turn and roast for another 15–20 minutes, until richly browned and easily pierced through the center. Taste and adjust the salt.

Notes

• Sunchokes can cause digestive discomfort for some people; serve a modest portion alongside the cauliflower and fish.

Overall Timing / Workflow

The vegetables roast first, leaving the final stretch for the delicate cod and butter sauce.

Instructions

1. 0:00 — Heat the oven to 425°F with racks in the upper and lower thirds. Scrub and cut the sunchokes, then start roasting them.
2. 0:10 — Prepare the cauliflower and put it in the oven on a separate pan. Chop the herbs and scallions; measure the sauce ingredients.
3. 0:25 — Turn the sunchokes. Pat dry and season the cod.
4. 0:35 — Turn the cauliflower and check the sunchokes. Remove the sunchokes when tender and browned, then place the cod on the freed rack. Rotate the remaining vegetable pan if browning unevenly.
5. 0:40 — Finish the cauliflower with garlic, olives, and capers. Remove when ready and toss with its fresh herbs and lemon.
6. 0:45 — Make the butter sauce while checking the cod. Keep the vegetables loosely covered and the sauce warm, not simmering.
7. 0:50–0:55 — As soon as the fish reaches 145°F, plate everything and serve.

Notes

• Allow about 1 hour total; thick cod portions or a crowded oven may need a few extra minutes.

Plating

Separate clusters preserve the vegetables' browned edges while allowing the caper-mustard butter to pool around the cod.

Instructions

1. Place a cod portion toward one side of each warm plate.
2. Arrange the spicy cauliflower beside the fish and mound the roasted sunchokes in the remaining space.
3. Spoon the caper-mustard butter over the cod, distributing the capers and herbs evenly. Let a little sauce run toward the cauliflower, but keep most of the sunchokes uncovered.

Leftover Path

Keeping the fish, vegetables, and sauce separate allows gentle reheating for the cod and hotter reheating for the roasted vegetables.

Instructions

1. Refrigerate leftovers in separate airtight containers within 2 hours. Eat the fish and sauce within 2 days and the vegetables within 3–4 days.
2. Reheat vegetables in a 400°F oven for 10–15 minutes, until hot and their edges regain some crispness.
3. Reheat the cod covered in a 275°F oven with a small splash of water until it reaches 165°F; avoid a hot skillet, which can toughen the flakes.
4. Warm the sauce very gently with a teaspoon of water, whisking to bring it together. Alternatively, flake cold cod into a salad with the leftover cauliflower, olives, and lemon.
