Chard-Wrapped Fish with Lemon and Olive

This elegant chard-wrapped fish with lemon and olive is a vibrant addition to any heart-healthy diet. By wrapping delicate fillets of white fish, such as cod or halibut, in earthy Swiss chard leaves, the moisture and flavour are locked in during the cooking process. The Mediterranean-inspired sauce, featuring zesty lemon, salty olives, and fresh coriander, provides a bright and savoury lift that perfectly complements the mild fish.

Ideal for a nutritious mid-week dinner or a light weekend meal, this recipe is as visually impressive as it is wholesome. The addition of cherry tomatoes adds a touch of sweetness, while the chard stems ensure nothing goes to waste, providing a lovely texture to the sauce. Serve this dish over a bed of fluffy couscous or basmati rice to soak up the delicious juices for a complete, balanced meal.

How to make Chard-Wrapped Fish with Lemon and Olive

Finely zest and juice both lemons. Reserve the juice and half the zest. In a small bowl, combine the remaining zest with the olives, 1 tablespoon of the olive oil, 2 tablespoons of the chopped coriander leaves, 1 teaspoon garlic, and the red pepper flakes until incorporated.

Bring a small pot of water to a boil over medium-high heat. Use a knife to separate the leaves from the chard stems so you have 2 leaves from each stem. Thinly slice the stems crosswise. Dip the chard leaves in the boiling water for 10 seconds to soften; drain, cool slightly, and pat dry. Cut the fish into 8 equal-sized pieces, season with salt and pepper, and spread 2 teaspoons of the olive mixture on each piece of fish.

Place 1 piece of fish on a piece of chard and roll it up; use the extra 2 leaves to patch any parts that need extra wrapping. Heat the remaining 45ml olive oil in a large skillet over medium heat. Add the onion and cook, stirring, until tender and lightly golden, 8 to 9 minutes. Add the chard stems with the remaining 3 teaspoons garlic and cook, stirring, until softened, 3 to 4 minutes. Add the flour and cook, stirring, until absorbed, 1 minute. Add the reserved lemon zest and juice with the stock, salt, and pepper and cook, stirring, until the liquid thickens and bubbles, 2 to 3 minutes. Stir in most of the remaining coriander.

Nestle the fish in the skillet, scatter the tomatoes and whole olives over the fish, reduce the heat to medium-low, cover, and cook until the fish is opaque and the chard can be cut easily, 10 minutes. Serve over the grain of your choice with sauce spooned over the top; garnish with coriander.
