Ingredients You’ll Need

This Baked Garlic Butter Cajun Cod comes together from a short list of pantry and fridge staples, each one pulling its weight to deliver bright color, aromatic flavor, or melt-in-your-mouth texture. Here’s what you’ll need to make this delicious, crowd-pleasing main course.

• Cod fillets: The star of the show! Look for firm, white fillets about 6 ounces each for perfect baking; frozen cod works well, as long as you thaw and pat dry thoroughly.
• Unsalted butter (melted): Butter infuses the fish with richness and ensures every bite is moist and delicious; using unsalted butter lets you control saltiness.
• Garlic (minced): Fresh garlic is a must for its pungent, mouthwatering aroma and savory bite—don’t skimp here!
• Cajun seasoning: The magical blend that gives this dish its smoky, slightly spicy southern flavor; feel free to adjust the heat to your taste.
• Lemon juice: A splash of lemon keeps flavors bright and adds just the right acidity to balance the richness.
• Olive oil: Just a bit helps the butter sauce cling to the fish and brings a subtle, fruity taste.
• Smoked paprika: This ups the color and introduces deep, earthy undertones with a hint of smokiness.
• Salt: A small but essential seasoning that enhances all the other flavors—taste your Cajun blend first to avoid over-salting.
• Fresh parsley (chopped): Adds a pop of color and a fresh, clean herbal note to finish the dish.
• Lemon wedges (for serving): Extra lemon brings the whole meal to life—squeeze to taste just before digging in.

How to Make Baked Garlic Butter Cajun Cod

Step 1: Preheat the Oven and Prep Your Baking Dish

Start by heating your oven to 400°F (200°C). This temperature is ideal for coaxing the cod into flaky tenderness without drying it out. Lightly grease a baking dish with olive oil or a spritz of cooking spray—this prevents sticking and makes cleanup a breeze. Place your cod fillets in the dish with a bit of space between each so they cook evenly.

Step 2: Mix the Garlic Butter Cajun Sauce

In a small bowl, combine the melted butter, minced garlic, Cajun seasoning, lemon juice, olive oil, smoked paprika, and salt. Stir gently to blend all those robust flavors into one fragrant, spice-speckled sauce—this is what transforms mild cod into Baked Garlic Butter Cajun Cod that’s bursting with personality.

Step 3: Brush and Coat the Cod Fillets

Generously brush the garlic butter Cajun mixture all over the cod fillets, making sure to coat every surface. The sauce will seep into the fish as it bakes, infusing it with buttery, garlicky, and zesty kick. Don’t worry if some of the sauce pools in the baking dish—that’s perfect for spooning over the finished fillets.

Step 4: Bake the Cod

Slide the baking dish into your preheated oven, and bake for 12 to 15 minutes. You’ll know the fish is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C). The top should glisten with melted butter and be tinged with golden Cajun spice.

Step 5: Garnish and Serve

As soon as the Baked Garlic Butter Cajun Cod emerges from the oven, sprinkle over the freshly chopped parsley for brightness and scatter lemon wedges around the dish. The pop of green and hint of citrus tie the whole meal together, making it beautiful and utterly irresistible.

Side Dishes

Pairing is easy—this cod is so versatile! Fluffy white rice or savory rice pilaf soaks up all the luscious pan sauce, while roasted vegetables (think asparagus, broccoli, or bell peppers) add vibrant color and nutrition. A crisp green salad is another fabulous way to round out your meal and keep things light.

Creative Ways to Present

For entertaining, try plating each fillet over a bed of herbed quinoa and finishing with microgreens and a lemon twist. Or, turn your Baked Garlic Butter Cajun Cod into tacos: flake the fish and serve in warm tortillas topped with slaw and avocado for a memorable twist. The flavorful sauce even makes this dish perfect for scooping over garlic mashed potatoes or creamy polenta if you’re craving comfort.

Make Ahead and Storage

Storing Leftovers

If you have any Baked Garlic Butter Cajun Cod left, let it cool to room temperature before transferring to an airtight container. Store in the fridge for up to two days for best flavor and texture—the fish stays moist, and the Cajun spices continue to mingle.

Freezing

Baked Garlic Butter Cajun Cod can be frozen, though the texture of cod may become slightly more delicate after thawing. Wrap portions individually, place them in a freezer-safe bag or container, and store for up to two months. Thaw overnight in the fridge before reheating.

Reheating

To warm up leftovers, gently reheat fillets in a low oven (about 300°F) for 10 minutes or until heated through. Add a drizzle of melted butter or a spritz of lemon juice before serving to refresh the flavors. Avoid the microwave if you can, as it can make the fish tough or rubbery.

FAQs

Can I use frozen cod fillets for Baked Garlic Butter Cajun Cod?

Absolutely! Just be sure to thaw the cod completely in the refrigerator, then pat it dry with paper towels before seasoning and baking. This step is key to achieving that flaky, restaurant-quality texture.

Is there a way to make Baked Garlic Butter Cajun Cod less spicy?

You bet—simply dial back the Cajun seasoning or use a mild version, and consider omitting the smoked paprika if you’re extra sensitive to spice. You can also add a little honey or maple syrup to the butter for a touch of sweetness to balance the heat.

What other fish can I substitute for cod?

If cod isn’t available, try haddock, pollock, or even tilapia—each will soak up the garlic butter Cajun flavors beautifully. Adjust baking time as needed, since fillet thickness can vary between types.

Can I make Baked Garlic Butter Cajun Cod dairy-free?

Yes! Swap the butter for your favorite plant-based alternative or use extra olive oil. The dish will still deliver that signature punchy Cajun profile, with just a slightly different richness.

How do I prevent my cod from being dry?

Keep an eye on the baking time and check for doneness at the lower end of the suggested range. Cod cooks quickly, so it’s best to pull it from the oven as soon as it flakes easily and appears opaque—overcooking is the usual culprit for dry fish.
