If using frozen cod fillets, allow them to thaw in cold water before use. They defrost pretty quickly. Pat dry the cod with paper towels before seasoning and baking.
Preheat oven to 400 Fahrenheit.
In a small bowl combine olive oil, salt, black pepper and dried herbs. If you like the lemony flavor you can add 1 tablespoon of fresh lemon juice to the mix. But this is optional as we are going to add a slice for the fish later. If using garlic, add it now.
Add all the veggies in a mixing bowl and drizzle with herb oil mixture until fully coated.
Massage the cod fillets with oil mixture as well.
Prepare aluminum foil sheets enough for 1 portion of veggies and fish. Place the veggies in foil and gently fold to close the packets.
Bake the veggies in preheated oven for 15 minutes, then carefully open the foil packets and top with fish fillets, one per packet. Add a slice of butter and lemon slice on top of the fish.
Bake for another 15-20 minutes until vegetables are fork tender and fish flaky.
Serve the cod with more lemon wedges on the side and basted with generous amount of homemade chimichurri sauce.
Alternatively, this baked fish and veggies can be cooked in one single baking dish covered in foil. Follow the same steps as instructed but instead of foil packets place everything a casserole.
Depending on what veggies you’ll be using you can add everything together and bake until dish flaky and veggies tender. Unlike potatoes and carrots, vegetables such as zucchini, cherry tomatoes, green beans won’t require more than 15-20 minutes to bake in total. So, feel free to add the veggies, top with fish fillets and bake together fr 15-20 minutes. For more tips see the blog post Tip Section.
