Step‑by‑Step Instructions for Easy 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, golden roasted potatoes. While the oven heats up, you can prepare the potatoes, ensuring they are ready for roasting once the oven is hot and ready.
Step 2: Season the Potatoes
In a large mixing bowl, toss the halved baby potatoes with olive oil, garlic powder, paprika, salt, and pepper. Make sure they are well coated for maximum flavor. The vibrant colors of the spices will provide a visual signal that your potatoes are ready to crisp up in the oven.
Step 3: Roast the Potatoes
Spread the seasoned baby potatoes evenly on a baking sheet, ensuring they have space to roast properly. Place the baking sheet in the preheated oven and roast for 20–25 minutes. Halfway through, take a moment to flip the potatoes, allowing them to achieve that desired crispy texture on all sides.
Step 4: Prepare the Garlic Butter Sauce
While the potatoes are roasting, melt butter in a saucepan over medium heat. Once melted, add minced garlic and sauté for about 1–2 minutes or until it becomes fragrant and just starts to turn golden—this prevents the garlic from burning. Stir in fresh lemon juice and thyme, letting the flavors meld beautifully.
Step 5: Cook the Cod Fillets
Next, season your cod fillets with salt and pepper, ensuring each piece is well seasoned. In a skillet over medium-high heat, add a drizzle of olive oil, then carefully place the seasoned fillets in the pan. Sear them for about 3–5 minutes per side, cooking until they are golden and flake easily with a fork.
Step 6: Combine Cod and Sauce
Once the cod is cooked and has that perfect golden crust, pour the delectable garlic butter sauce over the fillets. Make sure each piece gets a generous amount, allowing the sauce to soak into the fish and enhance its flavor beautifully.
Step 7: Plate and Garnish
To serve your Easy Garlic Butter Cod with Roasted Potatoes, arrange the crispy potatoes on a plate alongside the cod. Drizzle any remaining garlic butter sauce over the plate, then finish with a sprinkle of fresh parsley for a pop of color. This harmonious presentation is not only visually appealing but also incredibly inviting.

Expert Tips for Easy Garlic Butter Cod
-
Pat Dry First: Make sure to pat the cod fillets dry before cooking. This enhances the sear and keeps your fish flaky instead of soggy.
-
Season Generously: Don’t skimp on seasoning! A proper amount of salt and pepper is crucial for bringing out the natural flavors of the cod.
-
Avoid Overcrowding: When roasting the baby potatoes, spread them out evenly on the baking sheet. Overcrowding them can lead to steaming rather than achieving that perfect crispy texture.

Easy Garlic Butter Cod with Crispy Roasted Potatoes Recipe FAQs
What type of cod should I use for the best flavor?
I recommend using fresh, high-quality cod fillets for the best taste. If you can’t find cod, haddock or tilapia are excellent substitutes, each offering a unique flavor profile that will still shine in this recipe.
How should I store leftovers?
Store any leftover Easy Garlic Butter Cod in an airtight container in the refrigerator. It will stay fresh for up to 2 days. For the best flavor, gently reheat in a skillet. You can also store roasted potatoes in the fridge for 3-4 days and reheat them in the oven for optimal crispiness.

Overcooking cod can lead to a dry texture. If you find yourself in this situation, I recommend soaking the cod in a bit of the leftover garlic butter for a few minutes before serving. This can help reintroduce moisture and enhance the flavor.
Are there any dietary concerns I should be aware of?
Yes, if you or someone in your household has seafood allergies, substitutions like chicken or even a firm tofu can work beautifully! For those with dairy restrictions, feel free to use plant-based butter in place of regular butter for the garlic sauce.
