- 4 cod fillets: Choose fresh or thawed fillets for the best texture and flavor.

- 4 cloves garlic, minced: Garlic brings a fragrant, savory depth that elevates the dish.
- 1 tablespoon Cajun seasoning: Adds that perfect blend of spices that make this cod irresistibly flavorful.
- 1 teaspoon smoked paprika: Gives a subtle smoky undertone to balance the heat.
- 1/2 teaspoon salt: Enhances and balances the flavors perfectly.
- 1/2 teaspoon black pepper: Adds gentle heat and peppery notes to the mix.

How to Make Baked Garlic Butter Cajun Cod Recipe
Step 1: Prepare the Oven and Pan
Start by preheating your oven to 400°F (200°C). This temperature is just right to cook the cod quickly while locking in moisture. Line a baking sheet with parchment paper or lightly grease it to prevent sticking, setting the stage for an easy cleanup and perfectly crisp edges.
Step 2: Create the Flavorful Garlic Butter Sauce
While the oven heats, combine your melted butter, minced garlic, Cajun seasoning, smoked paprika, salt, and black pepper in a bowl. This blend is where all the magic happens. The butter melts everything together, garlic amplifies the savoriness, and the Cajun spices give a tantalizing kick that makes this recipe unforgettable.
Step 3: Coat the Cod Fillets
Place your cod fillets evenly spaced on the prepared baking sheet. Use a brush or spoon to generously coat each fillet with the garlic butter mixture. Don’t be shy here—the more flavor, the better! This coating not only seasons the fish but also keeps it moist during baking.
Step 4: Bake to Perfection
Pop the baking sheet into your preheated oven and let the cod cook for 12 to 15 minutes. You’ll know it’s done when the fillets turn opaque and flake easily with a fork. This short baking time ensures the fish remains tender without drying out.
Step 5: Garnish and Serve
Once out of the oven, sprinkle with fresh parsley for a pop of color and freshness. Serve immediately with lemon wedges on the side—squeezing a bit of lemon over each piece just before eating brightens the whole dish and balances the buttery, spicy flavors beautifully.
How to Serve Baked Garlic Butter Cajun Cod Recipe

Garnishes
A simple sprinkle of fresh parsley provides a lovely contrast both visually and flavor-wise, lending a fresh herbaceous note. Lemon wedges are essential here, too, as their acidity perfectly cuts through the richness of the garlic butter and amplifies the dish’s brightness.
Side Dishes
This dish pairs wonderfully with light, complementary sides. Think fluffy rice to soak up any extra buttery sauce, steamed or roasted veggies for a wholesome balance, or even crispy roasted potatoes to add a comforting crunch. A crisp green salad with a tangy vinaigrette also pairs well by adding freshness.
Creative Ways to Present
For a fun twist, serve your Baked Garlic Butter Cajun Cod over a creamy polenta or alongside buttery garlic mashed potatoes. You can also plate the fillets on a bed of sautéed greens like spinach or kale for a restaurant-worthy presentation that’s sure to impress your guests every time.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Baked Garlic Butter Cajun Cod in an airtight container in the refrigerator for up to 2 days. The flavors intensify slightly overnight, making for a tasty next-day meal, but it’s best enjoyed fresh to appreciate the flaky texture fully.
Freezing
If you want to store this dish longer, freeze the cooked cod in an airtight container or heavy-duty freezer bag for up to 1 month. To avoid texture loss, freeze it without garnishes like parsley or lemon wedges, which are best added fresh after reheating.
Reheating
Reheat gently in a low oven (about 300°F/150°C) for 10-15 minutes to keep the cod moist and tender. Microwaving is quicker but risks drying out the fish, so if you’re short on time, add a little extra butter or a splash of water to keep things from drying out.
FAQs
Can I use a different type of fish for this recipe?
Absolutely! While cod is excellent for its flaky texture and mild flavor, other firm white fish like haddock, tilapia, or halibut can substitute well while still absorbing the garlic butter and Cajun spices beautifully.
How spicy is this Baked Garlic Butter Cajun Cod Recipe?
The Cajun seasoning gives a noticeable but moderate spice level that you can easily adjust by using more or less seasoning. If you prefer milder flavors, use a smaller amount or substitute with a mild paprika blend.
Is this recipe suitable for meal prepping?
Yes, it is! Because the cod reheats well while maintaining its flavor, this recipe is a fantastic option for preparing meals ahead. Just store portions separately and reheat gently when you’re ready to enjoy.
Can I make this recipe dairy-free?
If you want to avoid butter, you can swap it out for olive oil or a dairy-free margarine. While it changes the richness slightly, the garlic and Cajun spices still shine through and make a delicious dish.
What’s the best way to check if cod is cooked?
The cod is perfectly cooked when it turns opaque and flakes easily with a fork. Avoid overcooking, as this makes the fish dry. Time and visual cues together help nail the ideal texture every time.
Final Thoughts
With its unbeatable combination of buttery richness, garlicky goodness, and spicy Cajun flavor, the Baked Garlic Butter Cajun Cod Recipe is a true gem that’s easy to throw together yet feels special every time. Whether you’re feeding family or impressing guests, it’s a dish that brings warmth and excitement to the table. Give it a try—you might just find your new favorite weeknight dinner!
