“Fluff the couscous. Keep the beans bright and the cod moist.”
Tomatoes warm only briefly, keeping their shape beside the flaky fish.
The cod is seared for color and then set aside while the vegetables and broth build a shallow braise, and that braise is what actually cooks it through. Covered and gentle is the only route to fish that stays in flakes.
🐟 The promise: Cod reaches 145°F (63°C), couscous separates under a fork, and beans are crisp-tender.


“Prepare the base” starts Cod Lemon Herb Couscous in the large nonstick skillet and lidded saucepan: bring 2 cups chicken broth to a boil in the saucepan; stir in the couscous, cover, remove from heat, and rest for 8 minutes before fluffing with half the lemon zest. During “Return cod fillets safely,” nestle the cod into the vegetables, cover, and cook 4–7 minutes, until every fillet reaches 145°F (63°C) and flakes under gentle pressure.
“Finish with dill and parsley” closes Cod Lemon Herb Couscous: fluff the couscous with the remaining lemon juice, dill, and parsley; spoon the green beans and tomatoes over it and set the cod on top; keep the dill for this step so Cod Lemon Herb Couscous reaches the table with its fresh aroma and texture intact.
Bring 2 cups (480 ml) of the chicken broth to a boil in a saucepan. Stir in the couscous, cover it, pull the pan off the heat, and rest 8 minutes before forking it up with half the lemon zest.

Pat the cod portions dry and season them with the kosher salt, black pepper, the remaining lemon zest, and half each of the dill and parsley. Sear in 1 tablespoon (15 ml) of the oil, 2 minutes a side, then set aside.

Add the remaining oil and the diced onion to the skillet and cook 3 minutes. Stir in the green beans for 4 minutes, then the halved cherry tomatoes for 2 minutes, until several skins split and weep their juice.

Pour in the last of the chicken broth with half the lemon juice, scraping the fond from the pan floor. Simmer 3 minutes, so the green beans turn crisp-tender while keeping their color instead of going drab.

Nestle the cod portions down among the vegetables, cover the pan, and cook 4–7 minutes. Each fillet is ready when it reads 145°F (63°C) and the flesh separates into opaque flakes under gentle pressure from a fork.

Fluff the couscous with the remaining lemon juice and the rest of the dill and parsley. Spoon the green beans and tomatoes over it with their pan juices, then lay a cod portion on each plate.

The cod flakes cleanly at 145°F (63°C), the couscous separates under a fork, and the beans stay crisp-tender and green. After “Prepare the base,” if couscous remains firm, add hot liquid in small amounts; if the sauce is thin, move cod fillets to a clean plate and reduce it.
Divide dill between the cod seasoning and the finished couscous for savory depth and a fresh final note.
