How to Bake Cod
This method marinates the cod briefly in lemon juice while you sauté the vegetables, then finishes everything in the oven so the fish cooks gently in the tomato-fennel mixture. The steps below summarize the technique; see the full recipe card for exact measurements and nutrition details.
- Preheat and season: Preheat the oven to 400°F (204°C). Season cod fillets on both sides with lemon juice, a pinch of salt, black pepper, and a sprinkle of fresh thyme. Set the fillets aside to rest while you prepare the vegetables.
- Sauté the vegetables: Heat extra virgin olive oil in a large skillet over medium-high heat. Add sliced onion, thinly sliced fennel, halved cherry tomatoes, and thin garlic slices. Sauté about 10 minutes until the vegetables soften and the tomatoes begin to release their juices. Stir in drained and chopped capers, the vegetable broth, and the remaining salt; cook for another 4 minutes to meld the flavors.
- Bake: Transfer the tomato-fennel mixture to a baking dish and arrange the seasoned cod fillets on top, tucking lemon slices around the fish. Bake in the center rack of the oven for about 15 minutes, or until the fish is opaque and flakes easily with a fork. Garnish with chopped parsley and serve immediately with lemon wedges.

Variations
- Fish choices: Substitute any firm white fish such as branzino, red snapper, halibut, or tilapia depending on availability and preference.
- Onions: Use shallots or red onion for a slightly different sweetness.

Serving Suggestions
This baked cod is delicious on its own for a light meal, but it also pairs nicely with starchy or green sides:
- Starchy sides: Serve with steamed rice, pasta, or crusty bread to soak up the lemony tomato sauce.
- Greens: A peppery arugula salad, simple mixed greens, or roasted asparagus make bright, fresh accompaniments.
Storage and Reheating
- Refrigerate leftovers in an airtight container for up to 3 days.
- Reheat gently in a skillet over low heat or in the microwave until warmed through; avoid overcooking to keep the fish tender.
