What Ingredients You Will Need

This garlic butter baked cod recipe keeps things simple, but every ingredient plays its part in creating that irresistible flavor and texture. Here’s what you’ll need to make the magic happen:

• Fresh Cod Fillets (4 pieces, about 6 oz/170g each) – Look for boneless, skinless fillets. Fresh or thawed-from-frozen both work great. I like to use wild-caught cod for the best flavor and texture.
• Unsalted Butter (4 tablespoons/56g, melted) – Butter is the heart of this recipe. I always go for unsalted so I can control the seasoning. If you prefer, you can use a dairy-free alternative like vegan butter.
• Fresh Garlic (4 cloves, finely minced) – Garlic brings the bold flavor. Don’t skimp! If you’re in a pinch, jarred minced garlic works, but fresh is best for that punchy aroma.
• Lemon Juice (2 tablespoons/30ml, freshly squeezed) – A little acidity brightens the dish. Roll your lemon on the counter before cutting to get the most juice out.
• Fresh Parsley (2 tablespoons/8g, finely chopped) – For a burst of color and freshness. You can swap in dill or chives if you’re feeling adventurous.
• Paprika (1/2 teaspoon/1g) – I use smoked paprika for a hint of depth, but regular sweet paprika works too.
• Salt (1/2 teaspoon/3g, or to taste) – I like kosher salt for its gentle flavor, but sea salt works too.
• Black Pepper (1/4 teaspoon/1g, freshly ground) – Gives a little bite to balance the butter.
• Olive Oil (1 tablespoon/15ml) – For greasing the baking dish and adding a touch of richness. You can use avocado oil as a substitute.
• Lemon Wedges (for serving) – Slice up a lemon and serve alongside. It’s optional, but it really does make each bite pop.

Optional add-ins:

• Red Pepper Flakes – For a little heat, sprinkle 1/4 teaspoon over the cod before baking.
• Capers – Scatter a tablespoon over the fish for briny, tangy notes.
• Bread Crumbs – For a crispy top, toss 1/4 cup (20g) of panko with a teaspoon of olive oil and sprinkle before baking.

Substitution notes:

• If you can’t find cod, swap in haddock, pollock, or tilapia.
• For gluten-free, skip the optional bread crumbs or use gluten-free panko.
• Dairy-free? Use a plant-based butter—Earth Balance works great in my experience.

I’ve tested this with both fresh and frozen fish (just thaw completely and pat dry), and both turn out great. The beauty of this recipe is how flexible it is—use what you have, and it’ll still shine.

Equipment Needed

You don’t need fancy gadgets for this garlic butter baked cod recipe. In fact, the right basics will get the job done beautifully:

• Baking Dish (9×13-inch/23x33cm or similar) – Glass or ceramic both work. If you’re doubling the recipe, two smaller pans work fine.
• Small Mixing Bowl – For melting and mixing the garlic butter sauce. A microwave-safe bowl is handy for melting the butter quickly.
• Basting Brush or Spoon – To spread the garlic butter evenly over the fish. If you don’t have a brush, the back of a spoon or even clean hands work in a pinch.
• Measuring Spoons and Cups – For accurate amounts. I’m a stickler for measuring, especially with bold flavors like garlic and lemon.
• Sharp Knife and Cutting Board – For mincing garlic and chopping herbs.
• Paper Towels – For patting the fish dry before baking. This ensures the butter sticks and the cod turns out flaky, not watery.

Honestly, I’ve even baked this on a sheet pan lined with parchment when my casserole dish was in the dishwasher—no shame, it works! For clean-up, a quick soak of your pans in warm, soapy water makes life easier. If you use nonstick pans, avoid metal utensils to keep them scratch-free. And if you’re on a budget, supermarket basics get the job done just as well as pricier brands.

How to Make Garlic Butter Baked Cod

1. Preheat your oven and prep the dish:
   
   Set your oven to 400°F (200°C). Lightly grease a 9×13-inch (23x33cm) baking dish with 1 tablespoon (15ml) olive oil. This helps prevent sticking and adds a little extra richness.
2. Prepare the cod:
   
   Pat the cod fillets dry with paper towels. This step is crucial! If there’s excess moisture, the fish won’t bake up flaky. Lay the fillets in a single layer in the greased baking dish.
3. Make the garlic butter:
   
   In a small microwave-safe bowl, melt 4 tablespoons (56g) unsalted butter. Stir in 4 cloves minced garlic, 2 tablespoons (30ml) fresh lemon juice, 2 tablespoons (8g) chopped parsley, 1/2 teaspoon (1g) smoked paprika, 1/2 teaspoon (3g) salt, and 1/4 teaspoon (1g) black pepper.
   
   Tip: Letting the garlic sit in the hot butter for a minute or two infuses the butter with extra flavor.
4. Coat the fish:
   
   Pour the garlic butter mixture evenly over the cod fillets. Use a basting brush or the back of a spoon to make sure every bit is covered. If you’re adding bread crumbs or capers, sprinkle them on now.
5. Bake:
   
   Slide the dish into the preheated oven and bake for 15-18 minutes. The cod is done when it flakes easily with a fork and is opaque throughout. If your fillets are thicker than 1 inch (2.5cm), add 2-3 extra minutes. Don’t overbake or the fish can turn dry.
   
   Sensory cue: The kitchen will smell amazing, with buttery garlic and a hint of lemon in the air.
6. Finish and serve:
   
   Remove from the oven. Let the cod rest for 2-3 minutes—this helps the juices settle. Sprinkle on more fresh parsley and serve with lemon wedges for an extra zing.

Troubleshooting tips:

• If your garlic is browning too much, your oven might run hot—tent loosely with foil next time.
• Fish sticking? Try using parchment paper under the fillets or a silicone baking mat.
• If the sauce looks thin, spoon it over the fish again after baking to soak up the goodness.

Honestly, it’s hard to mess up. The most important tip? Don’t overbake the cod. Check at 15 minutes—if it flakes easily, you’re golden. This recipe is forgiving, but a minute or two can make all the difference between moist, flaky fish and something less memorable.

Cooking Tips & Techniques

Getting that perfect flaky texture with baked cod isn’t as intimidating as it seems, but I’ve learned a few tricks along the way to make it even easier. First, always pat your cod fillets dry before baking—this helps the butter stick and ensures the fish bakes up tender, not soggy. Moisture is the enemy of crisp, flavorful results!

When it comes to the garlic butter, melting the butter first, then adding the garlic, lets the flavors meld without burning the garlic. I once rushed and tossed raw garlic over the fish before melting the butter—it ended up uneven and a bit harsh. Lesson learned: Let the garlic infuse in warm butter for that mellow, rich taste.

Don’t be tempted to overbake! Cod is a lean fish, and just a couple of extra minutes can make it dry. I always check for doneness at the minimum bake time—poke the thickest part of the fillet with a fork. If it flakes easily and is opaque, it’s ready. If you’re multitasking, set a timer. Trust me, I’ve gotten distracted and slightly overdone it before. The difference between perfect and “just okay” is about 90 seconds!

If you want a golden top, switch your oven to broil for the last 2 minutes. Keep a close eye on it—broilers work fast. For extra flavor, sprinkle a pinch of flaky sea salt and fresh herbs right after baking. And here’s an unexpected trick: let the cod rest for a couple of minutes out of the oven. This helps all those buttery juices soak back into the fish instead of pooling in the dish.

For consistency, try to use fillets of similar thickness so they cook evenly. And always taste your butter mixture before pouring—sometimes lemons are super tart, and you might need to add a pinch of sugar to balance it out. Cooking is all about adjusting as you go!

Variations & Adaptations

One of the best things about this garlic butter baked cod recipe is how easy it is to tweak for different tastes and dietary needs. Here are some of my favorite adaptations:

• Low-Carb/Keto: Skip the bread crumbs and use extra butter or a sprinkle of almond flour for a crunchy topping that’s still carb-friendly.
• Dairy-Free: Use a good vegan butter. I’ve tried this with Earth Balance, and it’s still buttery and flavorful. You can also use olive oil, but the flavor will be lighter.
• Herb Swap: Change up the fresh parsley for dill, basil, or even cilantro for a whole new twist. In summer, I love tossing in fresh chopped chives from the garden.
• Spicy: Add 1/4 teaspoon of cayenne pepper or a sprinkle of red pepper flakes to the garlic butter for a gentle kick.
• Different Fish: If cod isn’t handy, this recipe works just as well with haddock, pollock, or even tilapia. Thinner fillets may need less time in the oven, so keep an eye out.
• Allergen Swap: For gluten-free, ensure you use gluten-free panko or skip the crumbs altogether. For nut allergies, avoid almond flour and stick to the basics.

My personal favorite twist? I sometimes add a handful of cherry tomatoes to the baking dish. They roast up sweet and juicy, soaking up the garlic butter and making a built-in side dish. Play around, and don’t be afraid to make it your own!

Serving & Storage Suggestions

This garlic butter baked cod is at its best fresh from the oven, with the top still sizzling and the lemony aroma wafting through the kitchen. I like to serve it piping hot, straight from the baking dish onto warmed plates. Garnish with extra parsley and a squeeze of fresh lemon for a little pop of color and brightness.

For a complete meal, pair with fluffy rice, roasted potatoes, or a crisp green salad. Steamed veggies like asparagus or green beans are perfect for soaking up those buttery juices. If you’re feeling fancy, a glass of chilled white wine (like Sauvignon Blanc) makes a lovely match.

Leftovers? Let the cod cool completely, then transfer to an airtight container and refrigerate for up to 2 days. To reheat, cover loosely with foil and warm in a 325°F (160°C) oven for 8-10 minutes, or microwave in 30-second bursts until just heated through (don’t overdo it, or the fish can dry out). You can also enjoy it cold, flaked over salads or tucked into wraps for a quick lunch.

If you want to freeze, wrap individual baked fillets tightly in plastic wrap and then foil. Freeze for up to 1 month. Thaw overnight in the fridge before reheating gently. The flavors deepen as it sits—sometimes, the leftovers are even better the next day!
