Step‑by‑Step Instructions for Easy Garlic Butter Cod With Roasted Potatoes
Step 1: Preheat Oven
Begin by preheating your oven to 425°F (220°C). This high temperature is essential for achieving those crispy, golden-brown baby potatoes that will complement your Easy Garlic Butter Cod beautifully. While the oven heats up, get ready to prepare your potatoes.
Step 2: Prepare Potatoes
In a large mixing bowl, toss halved baby potatoes with olive oil, garlic powder, paprika, salt, and pepper until well-coated. The olive oil ensures that each piece gets crispy as it roasts. Transfer the seasoned potatoes to a baking sheet in a single layer for even cooking, making sure they aren’t overcrowded.
Step 3: Roast Potatoes
Place the baking sheet with the potatoes in the preheated oven and roast for 20-25 minutes. Flip the potatoes halfway through to ensure they get nicely crispy on all sides. When they are golden and tender, you’ll know they are ready to come out and wait for the cod to shine.
Step 4: Make Garlic Butter
While the potatoes are roasting, melt unsalted butter in a small saucepan over medium heat. Add freshly minced garlic and sauté for about 1-2 minutes until fragrant, being careful not to let it burn. Take it off the heat, then stir in freshly squeezed lemon juice and chopped thyme for an aromatic garlic butter sauce that elevates your cod.
Step 5: Cook Cod
Season your cod fillets generously with salt and pepper. Heat a drizzle of olive oil in a skillet over medium-high heat. Carefully place the cod into the hot skillet, cooking for about 3-5 minutes on each side until it develops a golden crust and is flakey when tested with a fork, ensuring that it reaches an internal temperature of 145°F (63°C).
Step 6: Combine Cod and Sauce
Once your cod is beautifully cooked, turn off the heat and pour the rich garlic butter sauce over the fillets in the skillet. This step will infuse all the garlicky goodness deep into the fish, creating a luscious flavor profile that will delight your taste buds.
Step 7: Serve
To plate your dish, serve a generous portion of the Easy Garlic Butter Cod alongside the crispy roasted potatoes. Drizzle any remaining garlic butter from the skillet over the top, and finish with a sprinkle of freshly chopped parsley for a pop of color. Enjoy the wonderful flavors you’ve created!
