Garlic Butter Cod with Roasted Potatoes Ingredients
For the Cod
- Cod – A lean protein source rich in omega-3 fatty acids; if cod is unavailable, consider using haddock or tilapia.
- Butter – Essential for creating the rich garlic butter sauce; using unsalted butter offers better seasoning control.

- Lemon Juice – Adds a bright acidity that complements the fish; lime juice makes a great alternative for a different twist.
- Fresh Thyme – Enhances the flavor profile with earthy notes; if dried thyme is on hand, use 1/3 of the fresh amount.
- Salt and Pepper – Basic seasonings that pack flavor; adjust according to taste.
For the Roasted Potatoes
- Baby Potatoes – Provide a delightful texture and are a good source of potassium; halving or quartering ensures even cooking.

Step‑by‑Step Instructions for Garlic Butter Cod with Roasted Potatoes
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). This temperature is perfect for achieving crispy roasted potatoes while keeping the cod tender and juicy. It’s essential to let the oven reach this temperature before you place the potatoes inside, ensuring they begin roasting immediately.
Step 2: Prepare the Potatoes
While the oven is heating, prepare the baby potatoes by halving or quartering them for even cooking. In a large bowl, toss the potatoes with a drizzle of olive oil, salt, pepper, and garlic powder until they’re well-coated. Spread them out in a single layer on a baking sheet for optimal roasting.
Step 3: Roast the Potatoes
Place the baking sheet in the preheated oven and roast the potatoes for about 20-25 minutes. Halfway through, give them a stir or flip them to promote even browning and crispiness. They should emerge golden and tender—try piercing one with a fork to ensure it’s just right.
Step 4: Create the Garlic Butter Sauce
While the potatoes are roasting, melt unsalted butter in a saucepan over medium heat. Once melted, add the minced garlic and sauté for about 1-2 minutes, just until fragrant; be careful not to let it brown, as burnt garlic can taste bitter. Remove from heat and stir in fresh lemon juice and thyme, setting aside the garlic butter sauce.
Step 5: Cook the Cod
In a skillet over medium-high heat, add a little oil and let it heat up. Season your cod fillets with salt and pepper, then place them in the hot skillet. Cook the cod for 3-5 minutes on each side, or until it turns golden brown and flakes easily when tested with a fork.
Step 6: Combine Cod and Sauce
After the cod is cooked, pour the garlic butter sauce over the fillets in the skillet, allowing it to soak in for about a minute. This step enhances the flavor of the cod, making it even more delicious and aromatic.
Step 7: Serve the Dish
To serve your Garlic Butter Cod with Roasted Potatoes, plate the crispy potatoes alongside the garlic-buttered cod. Drizzle with any remaining sauce from the skillet, and garnish with fresh parsley and lemon wedges for a bright, fresh touch. Enjoy the delightful flavors and textures of your meal!
Expert Tips for Garlic Butter Cod with Roasted Potatoes
-
Perfectly Preheated Oven: Make sure your oven is preheated to 425°F (220°C) before roasting for the best texture in your potatoes.
-
Dry Before Cooking: Pat the cod fillets dry with a paper towel before seasoning to achieve a better sear and prevent sticking during cooking.
-
Mind the Garlic: Sauté garlic just until fragrant; overcooking can lead to bitterness, ruining the rich flavor of the garlic butter sauce.
-
Watch the Cod: Cook cod until it’s opaque and flakes easily with a fork. Aim for a final internal temperature of 145°F (63°C) to ensure it’s safely cooked.

Storage Tips for Garlic Butter Cod with Roasted Potatoes
Fridge: Store leftovers in an airtight container for up to 2 days to maintain freshness. Reheat gently on the stovetop to preserve texture and flavor.
Freezer: If you want to store this dish longer, freeze cooked cod and potatoes in separate airtight containers for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating: Reheat in the oven at 350°F (175°C) for about 10-15 minutes to retain the cod’s moisture and the potatoes’ crispness. Avoid microwaving, as it can make the fish rubbery.
Avoiding Storage Issues: Ensure that both the garlic butter cod and roasted potatoes are completely cooled before sealing to prevent condensation, which can lead to sogginess.

Garlic Butter Cod with Roasted Potatoes Recipe FAQs
What kind of cod should I use for the best flavor?
Use fresh cod fillets for superior taste and texture. If fresh isn’t available, frozen cod works well too—just ensure it’s properly thawed before cooking. My personal favorite is wild-caught cod, as it tends to be more flavorful and sustainable.
How do I store leftovers of Garlic Butter Cod with Roasted Potatoes?
After enjoying your meal, be sure to cool the leftovers completely before placing them in an airtight container. They can last in the refrigerator for up to 2 days. For the best texture upon reheating, warm the cod gently on the stovetop or in an oven set to 350°F (175°C) for 10-15 minutes.
Can I freeze this dish, and what’s the best method?
Absolutely! To ensure the best quality, freeze the cooked cod and roasted potatoes separately in airtight containers for up to 3 months. When you’re ready to enjoy, simply transfer them to the fridge to thaw overnight, and then reheat in the oven for that crispy finish.
What should I do if my cod isn’t browning properly?
To achieve that lovely golden crust, make sure your skillet is fully preheated before adding the fish. Pat the cod fillets dry before seasoning them, as moisture can prevent browning. If your cod releases too much moisture while cooking, ensure not to overcrowd the pan, allowing each piece enough space for proper searing.
Can I make this dish gluten-free or dairy-free?
Yes! For a gluten-free version, double-check your seasonings to ensure there’s no hidden gluten. For dairy-free, simply substitute the butter with a plant-based alternative like vegan butter or olive oil, and use a splash of lemon instead of butter to maintain that rich flavor.
What’s the best way to tell if my cod is fully cooked?
Once cooked, the cod should be opaque and flake easily when tested with a fork. Using a food thermometer, check that the internal temperature reaches 145°F (63°C) for safe consumption. I often slice the thickest part of the fillet to check for doneness!
