Very quick to prepare and good for those watching their weight! This entree is ideal for Mondays when you would prefer to be on the couch rather than cooking in the kitchen.
Preheat your oven to 180°C (350°F), or set a large lidded pan over a gentle heat if using the stovetop method
Pat cod fillets dry with kitchen paper and set aside on a plate
Strip the thyme leaves from the sprigs and set aside
Peel and finely chop the onion
In a large nonstick pan, heat the olive oil over medium heat
Add the chopped onion to the pan and sauté gently for 3-4 minutes until softened but not colored
Pour the canned chopped tomatoes into the pan with the onion
Stir in the brown sugar, soy sauce, and reserved thyme leaves
Bring the tomato mixture to a gentle simmer and cook for 8-10 minutes, stirring occasionally
Taste and adjust seasoning if necessary (note: soy sauce adds salt)
While the sauce simmers, line a shallow ovenproof dish (or use the pan if ovenproof) and lay the cod fillets in a single layer
Spoon the hot tomato and thyme sauce evenly over each cod fillet
Cover the dish with foil or a lid
Bake in the preheated oven for 15-18 minutes until cod is opaque and flakes easily, or gently cook covered on the stovetop over low heat for 12-15 minutes
Check doneness by inserting a fork into the thickest part of the fillet; it should separate in large moist flakes
Plate each cod fillet with a generous layer of tomato and thyme sauce
Garnish with a small pinch of fresh thyme leaves if desired
Serve immediately, optionally with a side of steamed green beans or sautéed spinach
Enjoy your light, protein-rich Tomato and Thyme Cod
