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), which is essential for achieving perfectly crispy roasted potatoes. This high temperature will help the potatoes become golden-brown while keeping their insides tender. While the oven heats, gather your ingredients and prepare for the next steps.
Step 2: Prepare the Potatoes
Wash and halve the baby potatoes, then toss them in a mixing bowl with a generous drizzle of olive oil, salt, pepper, garlic powder, and paprika. Ensure every potato is evenly coated for the best flavor. Spread the seasoned potatoes in a single layer on a baking sheet, allowing space between them for that irresistible crispiness.
Step 3: Roast the Potatoes
Place the baking sheet in the preheated oven and roast the baby potatoes for 20–25 minutes. Flip them halfway through to promote even browning. They are ready when they’re golden, crispy on the outside, and tender when pierced with a fork. This step adds hearty texture to your Easy Garlic Butter Cod dinner.
Step 4: Make the Garlic Butter Sauce
While the potatoes roast, melt the butter in a small saucepan over medium heat. Add the minced garlic, sautéing until fragrant, about 1–2 minutes. Be careful not to let the garlic brown too much—this ensures a rich, aromatic sauce. Stir in the lemon juice and thyme to elevate the flavors of the garlic butter that will coat your cod.
Step 5: Cook the Cod
Season your cod fillets with salt and pepper on both sides. In a large skillet, heat a splash of olive oil over medium-high heat, then place the seasoned cod in the pan. Cook for 3–5 minutes per side until the fish is golden and flakes easily with a fork. This step ensures your cod turns out moist and bursting with flavor.
Step 6: Combine and Infuse
Once the cod is perfectly cooked, pour the garlic butter sauce over the fillets, allowing it to infuse for about a minute. This will not only enhance the taste of the cod but also give it a beautiful glossy finish. Meanwhile, ensure your roasted potatoes are still hot and ready for serving.
Step 7: Serve and Garnish
To plate your Easy Garlic Butter Cod with Crispy Roasted Potatoes, serve the cod alongside the golden potatoes. Garnish with fresh parsley for a pop of color and added freshness, and consider adding lemon wedges on the side for an extra zing. Enjoy the warmth and comfort of this delightful dish!

Expert Tips for Easy Garlic Butter Cod
• Pat Dry for Perfection: Make sure to pat your cod fillets dry before seasoning. This will help achieve a perfect sear, avoiding excess moisture that can lead to steaming rather than cooking.
• Don’t Crowd the Pan: When cooking the cod, give each fillet enough room in the skillet. This prevents moisture build-up and ensures that your fish cooks evenly, providing that sought-after crispy exterior.
• Check the Temperature: Use a food thermometer to check that the cod reaches an internal temperature of 145°F (63°C). This ensures both safety and optimal flakiness, leaving you with perfectly cooked Easy Garlic Butter Cod.
• Let the Flavors Marry: Allow the garlic butter to infuse over the cooked cod for about a minute. This melds the flavors beautifully, delivering a rich and satisfying experience.
• Experiment with Herbs: Don’t hesitate to swap out thyme for other fresh herbs like dill or parsley for a touch of your personal flavor. Different herbs can transform this dish while keeping it delicious.
• Crispiness is Key: Ensure your baby potatoes are spread out in a single layer on the baking sheet. This guarantees they roast to golden-brown perfection without steaming, giving you the ideal crispy texture to complement your meal.
