Ingredients
* 4 cod fillets (6 oz each, skinless & boneless)
* 3 Tbsp unsalted butter, melted (sub with ghee or vegan butter)
* 2 cloves garlic, minced (or 1 tsp garlic powder)
* 2 Tbsp fresh lemon juice (about 1 medium lemon)
* 1 tsp lemon zest (from the same lemon)
* 1 Tbsp fresh dill, chopped (or 1 tsp dried dill)
* 1 Tbsp olive oil (brand pick: California Olive Ranch)
* Salt and freshly ground black pepper, to taste
* Lemon slices, for garnish (optional)
Directions
1. Preheat the Oven
Preheat your oven to 400°F (200°C) and line a baking sheet or shallow dish with parchment paper or lightly brush with olive oil—this helps prevent sticking and makes cleanup a breeze.
- Season the Cod
Pat each fillet dry with paper towels, then season generously with salt and pepper. Dry fish means better sauce adhesion and flakier texture. - Whisk the Lemon‐Butter Sauce
In a small bowl, whisk melted butter with minced garlic, lemon juice, and lemon zest until you have a smooth, fragrant lemon-butter emulsion. Tip: let the butter cool slightly before adding juice to prevent separation. - Arrange Fillets and Drizzle Sauce
Place cod fillets skin‐side down (if skin on) on the prepared pan. Brush or spoon half of the lemon-butter sauce over each fillet, reserving the rest for basting later. - Bake to Perfection
Slide the pan into the oven and bake for 12–15 minutes, or until the fish is opaque and flakes easily with a fork (internal temperature of 145°F). For a lightly golden top, switch to broil for the last 1–2 minutes—watch closely to avoid burning. - Baste and Garnish
Remove from oven, baste fillets with the reserved sauce, and sprinkle with fresh dill. Garnish with lemon slices or a twist of lemon peel for color. - Serve Immediately
Transfer to warmed plates and serve with your favorite sides—steamed asparagus, quinoa, or a simple green salad are winners.

Storage & Reheating
Refrigerate leftovers in an airtight container for up to 2 days. To reheat, preheat oven to 350°F, place fillets in a baking dish, cover loosely with foil, and warm for 8–10 minutes until heated through. Microwave on medium power for 1–2 minutes if you’re in a rush—watch so the fish doesn’t overcook. Freeze unused sauce separately in a small container for up to 1 month, thaw overnight in the fridge.

A: Yes—prepare up to 2 days in advance, store in the fridge, and warm slightly before drizzling.
Q: What sides pair best with Lemon Butter Baked Cod?
A: Light grains like couscous, roasted root veggies, or a crisp arugula salad complement the zesty sauce.
Q: Is this recipe gluten-free?
A: It is naturally gluten-free—just double-check your butter (no additives) to be sure.
Q: Can I increase the recipe for a dinner party?
A: Easily—scale ingredients in proportion and bake in a larger pan; you may need an extra 2–3 minutes of cook time.
Q: What if my fish is overcooked?
A: Drizzle with a bit more melted butter and lemon juice to moisten, or serve with a creamy yogurt or aioli on the side.
