The cod fillets with leeks are a simple, tasty, and delicate main dish. These are fish fillets baked in the oven with a very easy leek-based sauce. The combination of cod, a lean and versatile fish, with leeks, which have a flavor similar to garlic and onion but much more delicate and slightly sweet, creates a particularly pleasant taste balance for the palate! A delicious dish that is ready on the table in less than 30 minutes.
The preparation is very simple: we cook the leeks in a pan with butter, adding the cream 5 minutes before the end of cooking. We season with salt and pepper. Pour the leeks into a buttered baking dish and place the cod fillets on top. Cover with wine and vegetable broth and bake for 20 minutes at 392°F. Transfer the fillets to a serving dish and reduce the leek sauce with the juice of half a lemon, then add the butter. Serve the fillets with the leek sauce and lemon zest.
