Hello friends! I'm writing from Virginia these past couple of weeks! While visiting my mom we made baked cod fish in foil for dinner one night and I am more than excited to share this with you! Not only because it is fabulous but incredibly easy too!
Big Chase, little Curren and I have been visiting family on the East Coast. Boy is it hot over on this side of the country! We are so not used to the humidity. It makes such a difference having the moisture in the air compared to living by west coast beaches. Kind of feels like being in a constant sauna. So I should be posting about ice cream with this heat index being so high but instead let's make baked cod fish...in foil!
Anyone else a super big seafood eater? My boys and I are for sure, freshwater seafood or saltwater seafood, we crave it. Well maybe mainly me since I hold the meal planning card in our household (hehe!)! Salmon, scallops, tuna, swordfish, shrimp and crab are among our meaty seafood favorites. For a dense flaky white fish we like cod, rainbow trout and flounder. Baked, grilled, marinated and sauteed fish... we will take it all!
One-dish meals baked in foil is all the rage lately, and for good reason. I actually bake like that often, as it is such an easy, clean way to make amazing dishes!
Why Baking Cod in Foil Works
Click to see why it works
- Lemon goes under the fish. The secret to delicious baked fish is slicing fresh lemon and placing the slices under the fish to bake. The acid slightly seeps into the filet without making it bitter.
- Less salt needed. The lemon flavors the fish just perfectly without much salt needed.
- Grape tomatoes roast sweet. Grape tomatoes are sweet and hearty with thick skin and less water than cherry tomatoes, so when they roast with fish they produce a slight sweetness.
- The broiler finishes it. Once the fish is baked, open the foil and broil it so the tomatoes crisp and burst with sweetness.
- Foil keeps it clean. One-dish meals baked in foil are such an easy, clean way to make amazing dishes.
- Cod is mild and healthy. Atlantic cod, Alaska cod and white fish in general are so healthy and mild in flavor.

Out of the herb you wanted for the foil packet? A tarragon substitute like basil or fennel fronds keeps the flavor bright with the lemon.

Expert Tips
- Lemon under, not over. The slices under the fish flavor it without turning it bitter.
- Fold the foil tight on the top and sides so the fish steams in its own juices.
- Open the foil to broil so the tomatoes crisp and burst with sweetness.
- Choose grape over cherry tomatoes. They hold their shape and roast sweeter.
- Make it ahead. Baked cod keeps in the refrigerator for up to 8 hours before serving.
My Go-To Way to Cook Fish
Ok, there is nothing fancy about baked cod fish. It is so easy this is my go-to technique for most seafood recipes. Don't tell the fishermen that get them and send them to the fisheries. They would all be appalled that I didn't fancy their fish the way they deserve. I just place it in foil. Oh the horror!
Time to fire up that oven, grab some foil and start roasting your baked cod fish! Enjoy!
