How to Make Cajun Garlic Butter Cod
This is a fast one skillet dinner, check it out. We start by rubbing the cod fillets with Cajun seasoning and sear them in oil and butter. We sweat garlic and shallot in that flavorful base, add spices and pour in chicken broth. We add butter and stir until melted it melt into that mixture, this will emulsify the sauce, while adding richness and sheen.
Next, we add the asparagus and let them simmer in the garlic butter sauce just until they start to soften. Finally we return the cod fillets to the skillet, let them simmer for a couple of minutes. Add a sprinkle of lemon juice and we’re ready to serve.
Ingredients, Tips & Substitutions
The Fish
- Cod Fillets: Use cod fillets of the same size and thickness so they can cook evenly. If you want to try this recipe with an other type of white fish, use haddock, hake, pollock, snapper or bass.
- Seasoning: A mix of salt, black pepper, garlic powder.
- Cajun seasoning: You can use store-bought or make your own to get the right balance of flavors. You can find my favorite blend in the recipe notes.
- Unsalted Butter and Olive Oil: For searing the cod fillets. We would never get the same crispy sear with only oil, and butter alone would burn.
Butter Garlic Sauce
- Asparagus: Try to use baby green asparagus. If you only can find the larger ones, you’ll need to cut them halfway lengthwise for a faster cooking time. Swap asparagus for broccolini, green peas, spinach or zucchini.
- Garlic: Freshly minced garlic is the way to go in this recipe, try not to use pre-chopped store bought garlic. It has substantially less flavor, fresh garlic always tastes better.
- Shallot: An aromatic to lift up the flavor.
- Seasonings: A mix of salt, black pepper, dried sage, chili pepper and smoked paprika. If you want to swap sage, try it with dried thyme.
- Chicken Broth: To deglaze the skillet and create the base for the sauce. You can also use vegetable broth.
- Butter: Obviously, we can’t have a butter sauce without butter. I highly recommend to pick a good quality butter.
- Parsley: To add a little freshness.
- Lemon Juice: Adds a nice level of acidity and zing to the sauce and fish.
Recipe Notes
- Serve over rice, spoon the sauce over pearl couscous, toss it with pasta, orzo, creamy polenta or buttery mashed potatoes.
- Pair with a leafy salad or roasted vegetables.
- Swap cod fillets for chicken fillets, shrimp or cauliflower steaks.
- Make your own Cajun spices: 2 tbsp smoked paprika, 2 tsp each onion powder + garlic powder, 1 tsp each dried thyme + dried oregano + salt + black pepper + cayenne pepper + chili powder + ground cumin.

Can you please tell me what that other ingredient is? Looks like barley or couscous???
The recipe looks great!
Hi Holly, it’s pearl couscous. Enjoy the recipe!
How do you keep the cod from falling apart while searing? It’s sooo flakey
Hi Jess, I typically purchase cod loin as it is thicker and firmer. When cooked, it remains flaky and does not easily break apart. Let me know if you have any more questions. Happy cooking!
Hello how do you do your couscous as a side? Anything special or just plain? Thanks!!
Hi, just plain, you’ll have plenty of sauce to serve over couscous. Enjoy the recipe!
It tasted great! It’s just annoying that cod loins have become so expensive.
Hey Reiner, love to hear that you enjoyed this recipe! Thank you so much for making it and your comment. Have a great day!
This was ok, it was incredibly salty. I will have to omit the added salt next time.
Thank you for your feedback Joanna! Some Cajun seasonings do contain salt, so it’s a great idea to either use no extra salt or taste the seasoning beforehand to adjust accordingly. Thanks for taking the time to share your experience!
