Step‑by‑Step Instructions for Lemon Garlic Butter Baked Cod
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures that your Lemon Garlic Butter Baked Cod will cook evenly and develop a beautiful golden color. Set your timer for 15 minutes, allowing ample time for the oven to reach the desired temperature while you prepare the rest of the dish.
Step 2: Prepare the Lemon
Slice half of a fresh lemon into thin rounds and juice the other half to collect about 1 tablespoon of zesty lemon juice. The lemon slices will serve as a flavorful base for your cod, while the juice enhances the garlic butter mixture. Set these aside to infuse the fish with bright citrus notes as it bakes.
Step 3: Arrange Lemon Slices
Place the lemon slices in a single layer at the bottom of a casserole dish. These slices will create a fragrant bed for the cod to rest on while baking, imparting their tangy goodness. Make sure they are spread evenly to maximize the flavor infusion throughout the fish during the baking process.
Step 4: Mix the Garlic Butter
In a small bowl, combine melted unsalted butter, minced garlic, and the freshly squeezed lemon juice. Whisk these ingredients together until well blended. This aromatic garlic butter will be drizzled over the cod, ensuring each bite of your Lemon Garlic Butter Baked Cod is infused with irresistible flavor.
Step 5: Season the Cod
Pat the cod loins or fillets dry with paper towels, then sprinkle them generously with lemon pepper seasoning and dried dill. Place the seasoned fish directly on top of the lemon slices in the casserole dish, ensuring the cod is well-coated. This step enhances the dish's zesty and savory profile, creating a delightful seafood experience.
Step 6: Pour the Garlic Butter
Carefully pour the prepared garlic butter mixture over the seasoned cod, making sure it covers the fish evenly. This rich layer will melt into the fish as it bakes, ensuring a luscious, moist texture. The mixture will create a beautiful glaze that adds both flavor and visual appeal to your Lemon Garlic Butter Baked Cod.
Step 7: Bake the Cod
Transfer the casserole dish to your preheated oven and bake for 15-20 minutes. Keep an eye on the cod; it’s ready when it turns opaque and flakes easily with a fork. This quick baking step allows the flavors to meld beautifully while keeping the fish moist and tender, making for a sumptuous dinner.
Step 8: Garnish and Serve
Once baked, remove the Lemon Garlic Butter Baked Cod from the oven and garnish with a sprinkle of chopped fresh parsley. This final touch not only enhances the dish's visual appeal but also adds a burst of freshness. Serve immediately alongside your choice of sides, enjoying the delightful flavors and aromas of this easy seafood dinner.

Make Ahead Options
