This simple roasted cod is lovely over fluffy rice. The juices make a great sauce. Or, try it with crusty bread to soak everything up. A simple green salad completes your weeknight fish recipe perfectly. This cod and tomatoes dish is so versatile. Which would you choose tonight?

Making It Last: Fridge, Freezer & Reheating Tips
Let’s talk about keeping your lovely cod tasty for later. First, let it cool completely. Then, store it in a sealed container in the fridge. It will be good for up to two days. You can also freeze it for a month. Wrap it tightly in foil first.
I remember my first time freezing fish. I just put the whole baking dish in! What a mess. Now I wrap each piece individually. To reheat, use your oven at 300 degrees. This keeps the fish moist. A microwave can make it rubbery.
Batch cooking this recipe is a smart move. Double the butter sauce and tomatoes. Cook two dishes at once. This saves you time and energy on a busy night. Having a healthy meal ready matters. It means you can relax instead of stressing over dinner.

Simple Fixes for Common Kitchen Hiccups
We all face little problems when cooking. Here are three easy fixes. First, fish sticking to the pan? Make sure your baking dish is well-coated with that garlic butter. I once forgot this step. Let’s just say the cod lost its skin.
Second, bland food? Do not be shy with salt. Season your fish right before it goes in the oven. This matters for flavor. Salt wakes up all the other tastes. Third, soggy tomatoes? Spread them in one layer around the fish. Crowding them makes them steam.
Fixing these small issues builds your confidence. You learn that a tiny change makes a big difference. Your one pan cod with cherry tomatoes will turn out perfect every time. Cooking should feel good, not frustrating.
Which of these problems have you run into before?
Your Quick Questions, Answered
What is the best way to season cod?
For this easy baked fish recipe, season simply. Use salt and pepper right on the fillets. Then, the magic is in the sauce. The melted butter, lemon juice, garlic, and herbs will do the rest. This creates a lemon garlic herb cod that is full of flavor without being complicated. It is the perfect start to any healthy cod recipes.
How long to roast cod at 400?
Roast your cod at 400 degrees for 14 to 20 minutes. The time depends on how thick your fillets are. The fish is done when it reaches 145 degrees inside. It should flake easily with a fork. This method makes for a simple roasted cod that is perfectly tender. It is the heart of a true 30 minute cod dinner.
What herbs go best with cod?
Fresh parsley, thyme, or rosemary are wonderful with cod. Dried herbs work too. Use about one tablespoon of fresh herbs. If using dried, use one teaspoon. These herbs make a classic herb roasted cod. They pair beautifully with the garlic and lemon. *Fun fact: parsley is a great source of vitamin C!*
Can I use frozen cod for roasted cod?
Yes, you can use frozen cod. Thaw it completely in the fridge first. Pat the fillets very dry with paper towels. This step is important. Wet fish will steam instead of roast. Once dry, treat it just like fresh fish. This tip makes this weeknight fish recipe even more flexible and easy for any night.
What to serve with garlic butter cod?
This baked cod recipe is a complete meal with the roasted tomatoes. For more sides, try fluffy rice or quinoa. They soak up the delicious juices. A simple green salad or steamed green beans also work well. The cod and tomatoes are so flavorful you do not need much else. It is a balanced, satisfying plate.
How do you keep roasted cod from drying out?
Do not overcook it. Use a timer and check at 14 minutes. The butter sauce also protects the fish. It bastes the cod as it cooks. Finally, let it rest for a minute after baking. The fish will finish cooking gently. This keeps your easy baked fish recipe wonderfully moist and flaky every single time.
