Sautéed Cod With Lentils

This elegant sautéed cod with lentils is a wonderful example of how simple, high-quality ingredients can create a deeply satisfying meal. The dish pairs flaky white fish with earthy French green lentils, which are celebrated for their ability to hold their shape and texture during cooking. Infused with caramelised onions, garlic and a bright hit of lemon juice, the lentils provide a robust and fibre-rich base that complements the delicate flavour of the pan-fried cod perfectly.

As a diabetes-friendly recipe, this meal is naturally low in sugar and high in lean protein, making it an excellent choice for those seeking a heart-healthy dinner. The combination of healthy fats from the olive oil and slow-release carbohydrates from the pulses ensures a balanced plate that feels truly indulgent. Serve with a crisp green salad or steamed seasonal greens for a complete and nutritious homemade supper.

How to make Sautéed Cod With Lentils

Cover lentils with cold water by 1 1/2 inches in a 2-quart saucepan and bring to a boil. Simmer, uncovered, until lentils are just tender, 12 to 25 minutes. Drain in a sieve set over a bowl and reserve 120ml cooking liquid.

While lentils are simmering, melt butter in a 2- to 3-quart heavy saucepan over moderately low heat, then stir in onion, garlic, and salt and cook, covered, stirring occasionally, until pale golden, about 10 minutes. Remove lid and cook, uncovered, stirring occasionally, until golden, 5 to 10 minutes more.

Stir in lentils and enough reserved cooking liquid to moisten (60 to 120ml ) and cook until heated through.

Just before serving, stir in parsley, lemon juice, pepper, and 1 tablespoon oil.

Pat fish dry and sprinkle with salt and pepper.

Heat butter and oil in a 10- to 12-inch nonstick skillet over moderately high heat until foam subsides, then sauté fish, turning over once, until browned and just cooked through, 6 to 8 minutes total.

Serve fish with lentils and drizzle with additional extra-virgin olive oil if desired.
