The Key Ingredients for Flawless Lemon Butter Baked Cod
The true charm of this dish is its elegant simplicity. You only require a handful of excellent ingredients to craft something utterly delicious. Here is what we need to have ready.

- Cod Fillets: Four portions, totalling around 680g (1.5 lbs). We find that thicker, centre-cut fillets yield the most succulent results.
- Unsalted Butter: About 85g (6 tablespoons), melted. Using unsalted butter gives us complete control over the final seasoning.
- Garlic: 3 to 4 cloves, minced very finely. Nothing beats the aromatic punch of fresh garlic.
- Lemon: One large, juicy lemon. We’ll be using both its zest and juice for a full, bright citrus flavour.
- Fresh Parsley: A small bunch, chopped finely, to garnish and add a final touch of freshness.
- Salt and Black Pepper: To your preference. We recommend sea salt flakes and freshly cracked black pepper.
- Optional: A little pinch of red pepper flakes for a subtle background warmth.
A Quick Word on Your Ingredients
For the very best texture and taste, we always suggest opting for fresh cod fillets. Search for pieces that are firm to the touch, with a translucent appearance and no overly fishy aroma. If frozen cod is what you have, that works wonderfully too! Simply ensure it is fully defrosted in the fridge overnight, then pat it very dry with kitchen roll to wick away any excess water before you begin.
Step-by-Step Guide: Let’s Begin Cooking!
Are you ready to make a little kitchen magic? This method is so wonderfully simple that you’ll have it committed to memory after just one go. Follow our easy steps to achieve perfectly flaky, flavourful cod every single time.
- Preheat and Prep: First, let’s get the oven preheating to 200°C (400°F / Gas Mark 6). Find a baking dish large enough to accommodate the cod fillets in a single layer with a little space between them and give it a light greasing.
- Season the Fish: Take your cod fillets and pat them completely dry with a paper towel. This is a vital step, as it helps the fish to bake to perfection rather than steam. Season both sides liberally with salt and pepper, then place them in your prepared dish.
- Mix the Wonderful Sauce: In a small bowl, whisk together the melted butter, finely minced garlic, lemon zest, and the juice from half of your lemon. This is your lemon butter sauce for fish, and it is simply divine! Give it a good stir to combine all the flavours.
- Pour and Arrange: Gently pour this beautiful butter sauce over each cod fillet, making sure some of the garlic sits on top of the fish. Cut the remaining lemon half into slices and arrange them on top of or around the fillets in the dish.
- Time to Bake: Pop the baking dish into your hot oven and let it bake for 12 to 15 minutes. The precise time will vary based on the thickness of your fillets. The cod is perfectly cooked when it turns opaque and flakes away easily with the gentle pressure of a fork.
- Garnish and Dish Up: Carefully take the dish out of the oven. Scatter over a generous amount of freshly chopped parsley for colour and freshness. We highly recommend spooning some of the delicious pan juices over the fish right before serving. Serve hot and enjoy!
Our Top Tips for Perfect Baked Cod
We want your every attempt at this dish to be a resounding success. Here are a few of our trusted tips to make sure your Lemon Butter Baked Cod is absolutely perfect.
Selecting the Finest Cod Fillets
The quality of your fish truly is paramount. When purchasing fresh cod, aim for fillets that are around 1 to 1.5 inches in thickness. These chunkier pieces are more forgiving and will stay beautifully moist during cooking. If you are using frozen cod, do remember to thaw it completely and pat it exceptionally dry.
The Secret to an Exquisite Lemon Butter Sauce
The real magic happens in the sauce! For the most vibrant flavour, you must use freshly squeezed lemon juice; the bottled variety simply doesn’t have the same zest. Also, take care not to let the garlic brown. For a milder garlic taste, you can gently warm the butter and garlic in a small saucepan for a minute to soften its flavour before you add the lemon juice.
How to Tell When Your Cod is Cooked to Perfection
The most common pitfall when cooking fish is overdoing it. To check if it’s ready, take a fork and insert it into the thickest part of a fillet, then give a gentle twist. The fish should flake apart effortlessly and have lost its translucent look in the centre. For complete accuracy, a digital food thermometer should read approximately 63°C (145°F).
Tempting Variations to Explore
While we believe this recipe is delightful just as it is, we encourage you to make it your own! Here are a few variations that we particularly enjoy:
- Aromatic Herbs: Introduce another layer of flavour by adding a tablespoon of freshly chopped dill or thyme into the butter sauce.
- A Touch of Spice: A small pinch of red pepper flakes or a dash of cayenne pepper will lend a lovely, subtle warmth to the sauce.
- One-Pan Wonder: Transform this into a complete meal by adding some quick-cooking vegetables. Asparagus spears, cherry tomatoes, or thinly sliced courgettes are all excellent additions. Simply toss them in a little olive oil before adding them to the dish.
What to Serve with Your Lemon Butter Baked Cod
This wonderfully versatile dish pairs beautifully with a wide array of side dishes. You can keep the meal light and simple or make it more substantial, depending on what you fancy. Here are some of our favourite accompaniments:
- Potatoes: Crispy roasted new potatoes, velvety mashed potatoes, or even simple boiled potatoes tossed with butter and herbs are all brilliant pairings.
- Grains: A bed of fluffy quinoa, nutty wild rice, or delicate orzo provides a healthy and filling foundation.
- Vegetables: Tender-stemmed broccoli, steamed green beans, or a crisp green salad with a light vinaigrette will round off the meal perfectly.
- Bread: Don’t forget a few slices of good, crusty bread. It’s essential for soaking up every last drop of that amazing lemon butter sauce!

Frequently Asked Questions (FAQ)
Can I use frozen cod for this recipe?
Yes, of course! Frozen cod is a great option. The most important thing is to ensure it has thawed completely before you begin cooking. We find the best method is to let it defrost overnight in the fridge. Once it’s thawed, use kitchen roll to pat it thoroughly dry to remove any excess moisture, which ensures the fish bakes rather than steams.
How should I store and reheat any leftovers?
Any leftover baked cod can be stored in an airtight container in the fridge for up to two days. When it comes to reheating, we suggest warming it gently in an oven preheated to 140°C (275°F) for 10-15 minutes, or until just heated through. This gentle approach helps the fish stay moist. We would advise against using a microwave, as it can make the texture of the fish a bit tough.
Can this recipe be made with other fish?
Absolutely! This lemon and butter sauce is wonderfully adaptable and tastes delicious with many other white fish. Feel free to try it with haddock, pollock, halibut, or even tilapia. You may just need to alter the baking time slightly to suit the thickness of the fillet you are using.
Is this recipe gluten-free?
Yes, this recipe is naturally gluten-free as written. The core ingredients—cod, butter, lemon, garlic, and fresh herbs—do not contain any gluten. As always, it is wise to double-check the labels on any packaged seasonings just to be certain.
The Wonderful Health Benefits of Cod
Aside from being incredibly tasty, cod is a superb choice for a healthy, balanced diet. It is an excellent source of lean protein, which our bodies need for growth and repair. Cod is also packed with vital nutrients like Vitamin B12 and iodine. Moreover, it provides heart-healthy omega-3 fatty acids, which are celebrated for supporting brain function and reducing inflammation. As the NHS points out, including fish in a balanced diet can play a key role in maintaining a healthy heart and good circulation.
