Cod is one of my favorite fish options. What I love about this protein option is its mild flavor and high versatility.

But, while there are many ways to prepare cod, my favorite will always be buttered cod. It takes this simple fish into something out of this world. It combines the delicate texture of the fish with rich, creamy butter.

Cod is not only a culinary fish, it’s also a nutrition powerhouse that can provide essential nutrients, keeping your family healthy.

Choosing the right ingredients is going to be essential to make this dish delicious and memorable.

When buying cod, freshness is key. Avoid fish that smells too fishy or has a slimy texture.

And, when possible, try to get wild-caught cod since I’ve found that it has a better flavor and texture than farmed-raised cod.

Once you buy the fish, store it in the coldest part of the fridge and use it within two days of the purchase.

While you can modify the dish by adding other ingredients, it can take away from the perfect simplicity of the dish. I’ve tried adding capers to pack a punch of flavor, and it works. As well as adding some mushrooms.

However, I have to admit that I always go back to the original recipe. 

Ingredients and Substitutes

1 1/2 lbs cod fillets – You can also use other fish options, like tilapia or a fattier option, like salmon. Look for fillets that are firm to the touch and have a mild, ocean-like scent.

Unsalted butter (6 tbsp) – Always opt for unsalted butter since it makes it easier to adjust and balance the flavor. You can always add more salt, but you can never remove salt from the dish.

Garlic powder (¼ tsp) – You can also use garlic flakes. 

Onion powder (1/4 tsp) – You can also use onion flakes.

Paprika (¾ tsp) – If you don’t have paprika, you can use cayenne pepper or some chipotle powder.

Salt (½ tsp)

Ground black pepper (¼ tsp)

1/2 lemon

Fresh parsley – Don’t use dried parsley. Adding the fresh parsley adds some freshness to the meal that elevates the dish.

How to Make Lemon Buttered Cod

Step 1. Grab a small bowl and combine the garlic powder, onion powder, paprika, salt, and black pepper.

Step 2. Mix everything until it’s blended thoroughly. 

Step 3. Place the cod fillets in the bowl and coat them with the seasoning mixture. Make sure that each fillet is evenly coated.

Step 4. Grab a large skillet and place it over medium-high heat. Add 2 tbsp of butter and place the cod. It will be easy enough to do that.

Step 5. Cook the cod for 2 minutes. Then, gently flip to the other side. Add the rest of the butter and cook for 3-4 minutes.

Let the butter and the fish melt to complete the cooking. Make sure you don’t overcook the fish since it can start falling apart.

Step 6. Drizzle the skillet with some freshly squeezed lemon juice, and garnish with lemon wedges and fresh parsley.

Side Dishes for Buttered Cod

Buttered fish is a versatile dish that you can pair with a variety of sides and even beverages. Here are some of my favorite side options that I’ve found that help elevate the dish.

• Roasted vegetables. Roasted carrots, potatoes, and asparagus can complement the rich flavor of buttered cod.
• Rice pilaf. This makes a great light and fragrant option to side this amazing dish. It can also help absorb some of that buttery sauce from the cod. If you want a low-carb option, you can use cauliflower rice.
• Green salad. A fresh salad with mixed greens, cherry tomatoes, and a light vinaigrette can add some refreshing contrast to the richness of the cod.

Storage and Leftovers

If you happen to have leftovers, I know you are going to want to keep them. Storing them properly is going to ensure it remains as delicious as when you take it fresh from the pan.

For those who want to have it a couple of days after making it, place the buttered cod in an airtight container and store it in the fridge. It will stay fresh for 2-3 days.

Once you are ready to have the fish again, place the cod in a baking dish and cover it with aluminum foil. Preheat the oven to 300F and cook for 10-15 minutes, or until it’s heated through.  

While you can use the microwave, I’ve found that using it can result in rubbery and dry cod. So, it takes all the appeal from the dish.

If you need to store the cod for longer, you can also place it in the freezer. Wrap the cod in a tightly plastic wrap and place it in a freezer-safe bag or container.

You can keep it in the freezer for up to 1 month.
