Pro Tips Before You Start
Pat the cod dry before seasoning so it bakes evenly and does not release too much moisture.

If your fillets are thick, add a few extra minutes of baking time while checking for doneness.
How to Make Baked Cod with Tomato Herb Butter
Step 1 – Prepare the tomato herb butter
Melt unsalted butter in a small saucepan over low heat. Add minced garlic and cook gently until fragrant, then stir in halved cherry tomatoes and fresh herbs.
Step 2 – Finish the sauce
Cook the tomatoes just until they begin to soften. Add fresh lemon juice, then remove the sauce from the heat.
Step 3 – Season the cod
Pat the cod fillets dry with paper towels. Season both sides lightly with salt and pepper.
Step 4 – Arrange in the baking dish
Place the cod fillets in a lightly greased baking dish in a single layer. Pour the tomato herb butter evenly over the fish.
Step 5 – Bake until flaky
Bake uncovered at 400°F (200°C) for 12 to 15 minutes, or until the cod is opaque and flakes easily with a fork.
Step 6 – Garnish and serve
Top with extra fresh herbs, lemon zest, or cracked black pepper. Serve immediately while warm and tender.
What to Serve Them With
Serve this baked cod with roasted potatoes, rice, or creamy mashed potatoes for a comforting meal.
For a lighter option, pair it with steamed green beans, asparagus, or a crisp side salad.
Crusty bread is also perfect for soaking up the tomato herb butter sauce.
Variations / Substitutions
Use haddock, halibut, or tilapia if cod is not available.
Swap cherry tomatoes for grape tomatoes or chopped Roma tomatoes.
Add a pinch of red pepper flakes if you want a little heat.
Use dill or oregano instead of thyme for a different herb flavor.
Storage & Leftovers
Store leftover baked cod in an airtight container in the refrigerator for up to 2 days.
Reheat gently in the oven at a low temperature or in a covered skillet to avoid drying out the fish.
Freezing is not recommended because cooked cod can become watery and delicate after thawing.
