Mashuai is Oman's coastal celebration dish: a whole kingfish rubbed with turmeric, garlic, ginger, lemon and coriander, roasted on a spit over coals until the skin crisps, and served over lemon rice with daqoos, a garlicky tomato-chile sauce. Our version keeps the flavors and changes the method: thick fish fillets get the same rub and roast on a sheet pan in a very hot oven, while the rice cooks with turmeric, lemon zest and juice until yellow and sharp. It is a light, bright dinner with a little warmth from the sauce.

Why it's on our list

Oman has a long coastline and a cooking tradition shaped by Indian Ocean trade, and mashuai is the dish that puts its fish and its lemons at the center of the plate. The adaptation is big: a whole spit-roasted kingfish is a weekend-with-a-grill project, and this is a weeknight sheet-pan dinner that borrows its spice rub and its rice, which is why the title says "inspired." It is feasible because the fish roasts in 12 minutes while the rice finishes. What I expect to learn is the Omani lemon rice, which uses both zest and juice and is tangier than any I have made. Heat lives entirely in the daqoos, so my son's plate will be fish and rice with the sauce left off.

Field notes · Origin & culture

Mashuai (from the Arabic for "roasted" or "grilled") is a dish of Oman's coast, traditionally made with kingfish, the local name for a large Indo-Pacific mackerel that is Oman's most prized eating fish. The fish is marinated in turmeric, garlic, ginger and lemon, roasted whole on a spit over an open fire, and served with lemon rice. Omani cooking sits at a crossroads: centuries of Indian Ocean trade brought spices, rice and methods from India, Persia and East Africa, while the interior kept a Bedouin tradition of dates and slow-cooked meat. Oman is also the historic source of the dried limes used across the Gulf and Iran, where they are still called "Omani limes."

Noteworthy ingredients

  • Fish: King mackerel is the real thing and is sold in Gulf Coast and Atlantic states; elsewhere, thick fillets of mahi-mahi, halibut, swordfish or cod take the rub well. Choose pieces at least 1 inch thick so they stay moist.
  • Turmeric: The rub's color and earthy base. Fresh turmeric, grated, is wonderful if you find it; ground is standard.
  • Lemons: Three, for zest and juice in the rice and the rub. A pierced dried lime cooked in the rice is a good addition if you have one.
  • Daqoos: A quick tomato sauce with garlic and chile, the standard companion to Omani rice dishes. Seed the chile or use half to keep it mild.

Prep — 15 min

  1. Rinse the rice until the water runs clear and soak it in cold water while you prep.
  2. Zest 2 lemons and juice all 3.
  3. Make the rub: grate 4 garlic cloves and the ginger, and mix with 1 teaspoon turmeric, the coriander, cumin, cardamom, 1 teaspoon salt, 2 tablespoons lemon juice and 1 tablespoon oil into a paste. Pat the fish dry and coat it on all sides.
  4. For the daqoos, chop the tomatoes and mince the remaining 2 garlic cloves; seed and mince the chile (half for a milder sauce).
  5. Slice the red onion thin and the cucumber into half-moons; toss with 1 tablespoon lemon juice and salt. Chop the cilantro.

Cook — 35 min

  1. Heat the oven to 450°F with a rack in the upper third.
  2. Lemon rice: heat 1 tablespoon oil in the rice pot over medium heat, add the lemon zest and remaining 1/2 teaspoon turmeric and stir 30 seconds. Add the drained rice, stir to coat, then add 2 1/4 cups water, 3/4 teaspoon salt and the dried lime if using. Bring to a boil, cover, and cook on the lowest heat 15 minutes; rest 10 minutes, then stir in 3 tablespoons lemon juice and fluff.
  3. Daqoos: heat 1 tablespoon oil in a small saucepan over medium heat, cook the garlic and chile 1 minute, add the tomatoes, tomato paste, 1/4 teaspoon salt and 1/4 cup water, and simmer 10 minutes until saucy.
  4. When the rice has 12 minutes left, lay the fish on an oiled sheet pan and roast 10–14 minutes depending on thickness, until the rub has darkened at the edges and the fish flakes at the thickest point (about 140°F). Do not turn it.
  5. If you have a grill, cook the fish over medium-high direct heat instead, 4–5 minutes per side, for the char the dish deserves.

Serving

Spread the yellow rice on a platter, lay the fish on top, and scatter cilantro over everything with lemon wedges around. The daqoos and salad go in bowls on the side; the adults will spoon the sauce over, and my son's plate gets fish, rice and cucumber with the sauce kept off until he asks. Leftovers keep two days; the rice reheats with a splash of water, and cold fish flaked into it with lemon makes a good lunch.
