There’s nothing quite like the smell of cod baking in the oven with butter and lemon. It’s one of those dishes that seems fancy but couldn’t be easier to make. I discovered this technique a few years ago when I was trying to figure out what to do with a beautiful piece of cod I’d picked up at the market.
Cod is perfect for kosher cooking because it’s naturally mild and takes on whatever flavors you pair with it. The key to this recipe is getting the temperature just right. Too hot and you’ll end up with dry, flaky fish that falls apart. Too cool and it won’t cook through properly. I bake mine at 400°F, which gives you that perfect balance of a slightly golden top and tender, moist fish inside.
Why Cod Works So Well for This Dish
The lemon butter sauce is what really makes this dish shine. I use a good amount of fresh lemon juice mixed with butter, garlic, and a touch of white wine. The wine isn’t essential, but it adds a nice depth of flavor. You can substitute it with a little extra lemon juice and a splash of vegetable broth if you prefer. Fresh dill or parsley work beautifully here too.
The Secret to Perfect Lemon Butter Sauce
This cod pairs wonderfully with roasted vegetables like asparagus or Brussels sprouts, or keep it simple with some steamed broccoli and rice. It’s elegant enough for Shabbat dinner but easy enough for a weeknight meal. The whole thing takes about 20 minutes from start to finish, which makes it perfect when you want something that feels special without spending hours in the kitchen.

Ingredients
Method
- Preheat your oven to 400°F. Lightly grease a 9x13 inch baking dish with olive oil.
- Pat the cod fillets completely dry with paper towels. Season both sides with salt and pepper, then arrange in the prepared baking dish with space between each piece.
- In a small bowl, mix together the softened butter, lemon juice, lemon zest, minced garlic, and white wine (if using). Stir until well combined.
- Spoon the lemon butter mixture evenly over each cod fillet, making sure to get some of the mixture around the fish in the pan.
- Bake for 12-15 minutes, or until the fish flakes easily with a fork and reaches an internal temperature of 145°F. The exact time will depend on the thickness of your fillets.
- Remove from oven and immediately sprinkle with fresh dill. Spoon any pan juices over the fish before serving.
