Ingredients You’ll Need

The ingredient list for Cod with Tomato and Herb Butter is refreshingly short, but each element pulls its weight, contributing either delicate flavor, contrasting texture, or a burst of color. Here’s what you’ll need and why every item matters.

Cod Fillets: Choose firm, fresh fillets for the perfect mild base that soaks up all the buttery herb flavors.
Olive Oil: Adds Mediterranean richness and keeps everything moist while baking.
Salt: Unlocks the natural sweetness of the cod and sharpens every other flavor.
Black Pepper: A touch of warmth to balance the dish and tie the herbs together.
Cherry Tomatoes: These burst while baking, adding juicy acidity and eye-catching color.
Unsalted Butter: Make sure it’s softened; this is the magic element that becomes a luscious herb sauce.
Garlic: Just a single clove, finely minced, infuses every bite with aromatic depth.
Fresh Parsley: Its bright green flavor is herbaceous and refreshing—don’t skip it!
Fresh Basil: Brings a classic, slightly sweet perfume that beautifully complements the tomatoes.
Lemon Zest: Lifts the whole dish with subtle citrus zing—always use fresh zest for best results.
Lemon Wedges: Squeeze over just before serving for a pop of brightness that wakes up every bite.

How to Make Cod with Tomato and Herb Butter

Step 1: Preheat and Prep the Pan

Start by preheating your oven to 400°F (200°C), so it’s hot and ready to work its magic. Lightly grease a baking dish with a little olive oil to keep things from sticking and help the fish stay gorgeously tender underneath that bubbling butter topping.

Step 2: Season the Cod Fillets

Pat the cod fillets dry with paper towels—this helps them sear slightly in the oven and soak up flavor. Season both sides liberally with salt and black pepper. Now, nestle the fillets into the prepared baking dish, spacing them out so each piece can cook evenly.

Step 3: Scatter the Tomatoes

Take your halved cherry tomatoes and scatter them around (and between) the cod fillets. As these roast, they release their sweet juices into the pan, flavoring the fish and creating little pops of tangy goodness in each forkful.

Step 4: Make the Herb Butter

In a small bowl, mix your softened unsalted butter with the minced garlic, chopped parsley, chopped basil, and fresh lemon zest. Stir until all the herbs are evenly distributed and the butter is fragrant and flecked with green. This is where Cod with Tomato and Herb Butter gets its signature richness and garden-fresh aroma.

Step 5: Dot with Herb Butter and Drizzle Olive Oil

Divide the herb butter evenly over the cod fillets, dotting generous spoonfuls right on top. Finally, drizzle everything with two tablespoons of olive oil. This ensures both the fish and the tomatoes emerge glossy, tender, and packed with flavor.

Step 6: Bake to Perfection

Bake for 12 to 15 minutes, until the cod flakes easily when gently pressed with a fork and the tomatoes have softened and collapsed. If your fillets are especially thick, you might need another minute or two—just keep an eye out for that moment when they look pearly and just barely opaque.

Step 7: Serve Warm with Lemon

Remove your Cod with Tomato and Herb Butter from the oven and let it rest for a minute. Spoon any melted butter and pan juices over the top, and serve each fillet warm, with lemon wedges on the side for that finishing squeeze of acidity. It’s now ready to impress!

Garnishes

A handful of additional chopped parsley or basil sprinkled over the top adds a fresh, vibrant finish. Don’t forget a few more lemon wedges—some like a bigger burst of citrus with each bite! For extra flair, a drizzle of really good olive oil just before serving makes everything glisten.

Side Dishes

This cod sings alongside fluffy rice, nutty couscous, or a bowl of tender steamed green beans. You could also serve Cod with Tomato and Herb Butter with buttered baby potatoes, a leafy salad, or even herbed quinoa to soak up all those gorgeous juices.

Creative Ways to Present

For a dinner party twist, serve individual portions on top of a bed of wilted spinach or arugula—the warm herb butter will act as a ready-made dressing. Alternatively, flake the baked cod and spoon it with the tomatoes over toasted sourdough for a rustic take on bruschetta.

Make Ahead and Storage

Storing Leftovers

If you have any leftover Cod with Tomato and Herb Butter, transfer it to an airtight container and refrigerate within two hours of cooking. The cod will keep nicely for up to two days. Store any remaining pan juices separately for best flavor and to prevent the fish from getting soggy.

Freezing

While fresh is always best, you can freeze cooked portions of Cod with Tomato and Herb Butter. Let the fillets cool completely, then wrap them tightly in foil or parchment and place in a freezer-safe bag. Freeze for up to one month. Be aware that the texture may become slightly softer after freezing and thawing.

Reheating

To reheat, place the cod and tomatoes in a baking dish and warm in a 325°F (165°C) oven for about 10 minutes, until heated through. Spoon some reserved pan juices over the top to keep it moist, and finish with a fresh squeeze of lemon. Avoid microwaving, as it can dry out the delicate fish.

FAQs

Can I use frozen cod fillets for Cod with Tomato and Herb Butter?

Absolutely! Just thaw the fillets fully in the refrigerator overnight, then pat dry thoroughly before seasoning. Making sure they’re dry helps prevent excess water in the baking dish and ensures more flavorful results.

What herbs can I substitute if I don’t have fresh parsley and basil?

You can use dried herbs in a pinch—just use about one-third of the quantity (so, around 2 teaspoons parsley and 1 teaspoon basil). Dill or chives also work nicely and add their own twist on the flavor.

How do I know when the cod is perfectly cooked?

Cod is done when it’s opaque and flakes easily with a fork. Baking times might vary depending on thickness, but usually 12 to 15 minutes at 400°F is just right. If you have a meat thermometer, aim for 145°F in the thickest part.

Can I make Cod with Tomato and Herb Butter dairy-free?

Yes! Substitute the butter with a high-quality plant-based spread or olive oil-based butter alternative for a delicious dairy-free version. You’ll still get lots of rich flavor from the herbs, garlic, and olive oil.

Does this recipe work with other white fish?

Definitely. You can substitute cod with haddock, halibut, pollock, or even tilapia. Just adjust baking time slightly if your fillets are much thicker or thinner.
