Cod with Garlic-Herb Butter
The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions; to ensure that you have all the ingredients and equipment required, and to understand the steps and timings involved.
When you’re following a a certain eating plan, but the rest of the family isn’t, it can become annoying to think of different meals to suit everyone, can’t it?
However, when serving up a simple protein such as fish, it’s easy to add side dishes for everyone else, while you stick to the base meal.
Cod is a low-fat source of protein, so great if you eat low fat (just don’t slather it in butter like this recipe!), but it’s also low-carb, which is perfect if you are Keto – with the added fat (butter).
Then simply add a veggie choice for yourself (pictured is our simple oven-roasted asparagus). Then add a side of mashed potatoes for the rest of the family. It’s like a win-win fish dinner!
The herb and garlic butter is really easy to make, and you can make a big batch of it and leave it in the fridge to add to other recipes or grilled meat.
The cod is pan-seared which helps to seal in all the juices and flavor.
The recipe will work well with a variety of white fish including grouper, haddock, pollack, hake, sea bass, mahi mahi, tilapia, or snapper. Use the fish that is most sustainable in your area.

Ingredients & Equipment Used In This Recipe
You may already have some of the basic ingredients for this recipe – the full list with measurements is found in the recipe card at the end of this post.
For your convenience, any specialized or notable ingredients and equipment needed for this recipe have been listed below and linked to Amazon or other stores if available online.
- Fresh Herbs – parsley, thyme, and basil.
- Cod Fillets – this recipe uses Atlantic cod, but of course, this may change depending on where you live in the world.
Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog! I try to give American, imperial, and metric measurements in my recipes. You can mix cup measurements with weighted measurements, but never imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).

Atlantic Cod with Garlic-Herb Butter
Ingredients
For the Garlic Herb Butter
- 6 Tbsp unsalted butter softened
- 1½ tsp garlic finely minced
- 1 tsp fresh parsley finely chopped
- 1 tsp fresh thyme leaves
- 2 tsp fresh basil finely chopped
- ¼ tsp sea salt
To Cook
- 2 Tbsp extra virgin olive oil
- 6 4 oz / 100g Atlantic cod fillets
- Sea salt and black pepper to taste
- Fresh chopped parsley for garnish
Instructions
- Prepare the garlic-herb butter by combining all ingredients in a medium-sized bowl. Stir until the garlic, herbs, and salt are evenly distributed throughout the softened butter.
- Transfer the butter mixture to the center of a sheet of plastic wrap or parchment paper and form into a log. Wrap tightly and place inside the refrigerator for 15-20 minutes to become firm.
- Heat olive oil in a large skillet over medium-high heat. Pat the cod filets dry with a paper towel and season both sides with salt and black pepper, to taste.
- Add filets to hot skillet and cook for 2-3 minutes, or until they become golden brown. Reduce heat to medium and carefully flip each fillet. Top each filet with an equal amount of herb butter and continue cooking for another 3-4 minutes. While cooking, spoon the herb butter back over the filets as it melts.
- Remove from heat and transfer fillets to individual serving plates.
- Drizzle with melted herb butter and garnish with some fresh chopped parsley, if desired.
- Serve immediately with some oven-roasted asparagus tossed with remaining herb butter from skillet or your choice of sides. Enjoy!
