Sand Dabs with Brown Butter Caper Sauce, Basil-Dressed Roasted Vegetables & Corn
Delicate sand dabs get a golden crust and a generous spoonful of nutty brown butter, briny capers, lemon, and parsley. Roasted broccoli and sweet tomatoes take a bright basil-caper dressing, while juicy corn on the cob keeps this firmly in summer-dinner territory.

Golden Pan-Seared Sand Dabs
A very light cassava coating helps these delicate flatfish brown without turning them into heavily breaded fish. Ghee tolerates the searing heat while the brown butter is prepared separately.
Ingredients
- 8 small dressed sand dabs, heads and guts removed, about 2½–3 lb total
- ⅓ cup cassava flour, for a light dusting
- 3 tablespoons ghee, divided
- ¾ teaspoon kosher salt, or to taste
- ¼ teaspoon freshly ground black pepper
Instructions
- Pat the sand dabs thoroughly dry, including the cavities. Season lightly with salt and pepper.
- Heat a large nonstick or well-seasoned skillet over medium-high heat. Add enough of the ghee to thinly coat the bottom.
- Immediately before cooking each batch, dust the fish lightly with cassava flour and shake off all excess. Lay them in the skillet without overlapping.
- Cook for 2–3 minutes on the first side until golden and releasing easily. Turn carefully with a wide fish spatula and cook another 1–3 minutes, depending on thickness.
- Remove when the flesh is opaque, lifts easily from the backbone, and reaches 145°F in the thickest flesh without touching bone. Transfer to a warm platter, uncovered.
- Repeat with the remaining fish and ghee, wiping out scorched flour between batches. Spoon over the brown butter caper sauce just before serving.
Notes
- Have the fishmonger clean and trim the sand dabs. Serve bone-in and lift the cooked flesh from the central skeleton at the table.
- If using boneless fillets, allow about 1½ lb total and shorten cooking to roughly 1–2 minutes per side.
Brown Butter Caper Sauce
Browned milk solids provide the nutty depth; lemon and capers keep the butter lively rather than heavy. Parsley goes in off heat to retain its freshness.
Ingredients
- 6 tablespoons unsalted butter
- ¼ cup brined capers, drained, rinsed, and patted dry
- 2 tablespoons fresh lemon juice
- ¼ cup roughly chopped flat-leaf parsley
- to taste kosher salt and freshly ground black pepper
Instructions
- Melt the butter in a small, light-colored saucepan over medium heat. Swirl frequently as it foams.
- Cook until the milk solids are hazelnut brown and smell toasted, about 3–5 minutes. Add the dry capers carefully and cook for 30 seconds.
- Remove from the heat. Carefully stir in the lemon juice; it will sputter. Let the bubbling settle, then stir in the parsley.
- Taste before adding salt, since the capers contribute plenty. Add pepper and spoon over the fish while warm, including the browned solids.
Notes
- If the sauce tastes too sharp or salty, stir in a tablespoon of warm water. If the milk solids turn black or smell acrid, start again.
Roasted Broccoli & Summer Tomatoes
Large broccoli pieces develop crisp, deeply browned edges while their stems stay juicy. Adding tomatoes partway through roasting keeps them sweet and blistered rather than completely collapsed.
Ingredients
- 1½ lb broccoli, cut into large florets, thick stems peeled and sliced into ½-inch batons
- 1 pint red and yellow cherry tomatoes
- 6 oz cremini mushrooms, halved or quartered, optional
- 3 tablespoons extra-virgin olive oil
- ¾ teaspoon kosher salt, or to taste
- ¼ teaspoon freshly ground black pepper
Instructions
- Heat the oven to 425°F. Dry the broccoli well so it roasts rather than steams.
- Toss the broccoli and optional mushrooms with 2 tablespoons olive oil, salt, and pepper. Spread across a large rimmed sheet pan, with flat surfaces against the metal; use a second pan if crowded.
- Roast for 15 minutes. Turn the broccoli and add the tomatoes tossed with the remaining tablespoon of oil.
- Roast another 10–15 minutes, until the broccoli has dark golden edges and tender stems and the tomatoes are blistered.
- Transfer to a serving bowl and toss gently with the basil caper vinaigrette while still warm.
Notes
- Keep the vegetables in a single layer; crowded pans produce softer vegetables with much less browning.
Basil Caper Vinaigrette
A chopped rather than puréed dressing leaves fresh basil, briny capers, and little bites of shallot throughout the roasted vegetables.
Ingredients
- 1 small shallot, finely minced
- 1½ tablespoons red wine vinegar
- 2 tablespoons brined capers, drained and roughly chopped
- 3 tablespoons extra-virgin olive oil
- ½ cup loosely packed basil leaves, roughly chopped just before mixing
- to taste kosher salt and freshly ground black pepper
Instructions
- Combine the shallot and vinegar in a bowl and let stand for 5–10 minutes to soften the shallot's bite.
- Stir in the capers and olive oil. Fold in the freshly chopped basil just before dressing the vegetables.
- Season with pepper and only as much salt as needed. Toss with the warm roasted vegetables, starting with two-thirds of the dressing and adding more to taste.
Notes
- If the tomatoes release plenty of juice, fold that into the dressing rather than adding extra oil.
Steamed Corn on the Cob
Brief steaming preserves fresh corn's sweetness and plump texture. A simple finish leaves room for the rich fish sauce and herb-dressed vegetables.
Ingredients
- 4 ears fresh bicolor sweet corn, husks and silk removed
- 1 tablespoon unsalted butter
- to taste kosher salt
Instructions
- Bring an inch of water to a boil in a wide pot fitted with a steamer basket.
- Add the corn, cover, and steam for 6–8 minutes, until the kernels are hot, glossy, and crisp-tender.
- Remove from the pot, rub lightly with the butter, and season with salt. Serve hot.
Overall Timing / Workflow
The vegetables can wait briefly, but the fish is best straight from the skillet. Preparing the dressing and sauce ingredients early keeps the final minutes manageable.
Instructions
- 0:00 — Heat the oven to 425°F. Cut the vegetables, shuck the corn, and measure both sauces' ingredients.
- 0:15 — Put the broccoli and optional mushrooms in the oven. Macerate the shallot for the vinaigrette and pat the fish dry.
- 0:30 — Turn the broccoli and add the tomatoes. Bring the corn's steaming water to a boil and begin searing the fish in batches.
- 0:35 — Steam the corn. Finish the vinaigrette and brown the butter in a separate saucepan, either between fish batches or once the last batch is underway.
- 0:45–0:50 — Dress the roasted vegetables, finish the sauce with lemon and parsley, and plate immediately.
Notes
- Two skillets shorten the fish cooking time. Otherwise, keep the first batch on a warm platter, uncovered, and avoid stacking it.
Plating
Keeping the corn and vegetable dressing beside the fish preserves the golden crust while allowing the caper butter to pool around it.
Instructions
- Arrange two small sand dabs on each warm plate, slightly overlapping.
- Spoon warm brown butter, whole capers, and parsley along the center of the fish, leaving some crisp edges exposed.
- Add the basil-dressed vegetables beside the fish and place an ear of corn along the other side.
- Provide a small plate for fish bones.
Leftover Path
Removing the bones before storing makes delicate leftover fish easier to use. Corn and roasted vegetables also make a good next-day salad without another full cooking session.
Instructions
- Lift leftover fish from the bones. Refrigerate fish, vegetables, and corn in separate airtight containers within 2 hours.
- Use the fish within 1–2 days and the vegetables and corn within 3–4 days.
- For a cold lunch, cut the kernels from the cob and toss with the roasted vegetables and any reserved vinaigrette. Add the flaked fish gently at the end.
- For a hot meal, reheat the fish covered in a low oven with a splash of water until it reaches 165°F; avoid prolonged heating. Warm leftover brown butter gently and stir before spooning over.
