Cod is a great fish to cook since it’s low in fat, a good source of omega-3, vitamins and protein. I enjoy its mild flavor and how light, tender and flaky it is after cooking. The biggest plus is that this is one of the easiest fish to prepare.

What’s The Best Type Of Cod To Buy?

The two best types of cod are Pacific and Atlantic. Pacific cod (also known as true cod or gray cod) can be found near Alaska, in the Pacific Ocean. It is also in Japan and Canada. Atlantic Cod, which is a larger fish, can be found in the coldest water areas of the North Atlantic.

If you want to dive deeper (no pun intended) into the specifics of the best choice of cod, I highly recommend going to the Monterey Bay Aquarium Seafood Watch website. There you’ll find their recommendations on what’s the best fish to buy in order to have less of an impact on the environment. They also have a great phone app that you can use at the market when you’re trying to choose what fish to buy.

What’s the difference in taste between Pacific and Atlantic Cod?

Atlantic cod may have a slightly sweeter flavor than Pacific cod. For this recipe, I used Pacific cod.

What Should You Look For When Buying Cod Fillets?

With white fish, you want the flesh to look translucent. The fish should look wet and shiny. If the fish looks opaque, dry or smells funny, it’s not fresh. Don’t buy it!

How Long is Cod Good For After Purchasing?

Refrigerated cod is good for 1 to 2 days if properly stored. If you want to freeze the cod, place it in the freezer immediately after purchasing. Be sure to wrap in an air-tight freezer storage bag or paper. Remember to write the purchase date on the outside of the bag or paper.

How Long is Frozen Cod Good For?

Frozen cod is best used within 6 to 8 months for the best quality. After thawing and defrosting cod in the refrigerator, you have about 1 to 2 days to use it. Keep it refrigerated until use.

How Long Does Cod Last After It’s Cooked?

Cod will stay good for about 3 days after its cooked.

Tips To Make Cooking This Recipe Easier

slicing cherry tomatoes in half with a knife

The Tomatoes

Prep the cherry tomatoes by cutting them in half lengthwise. I used a cherry tomato medley with different colored tomatoes. You can use just one color (red, yellow, etc.). I like making my dishes as colorful as possible, which is why I chose the medley.

The Mushrooms

I sautéed the mushrooms in a nonstick skillet and cooked them just enough to soften the texture. They will continue to cook in the oven when they are added to the fish.

The Basil

Basil adds a fresh, peppery, slightly sweet flavor to this dish. The leaves are delicate, so you want to be gentle with them when you cut (chiffonade) them.
