Ingredients You’ll Need
- 600g cod fillets (fresh or frozen, thawed)
- 60g grated Parmesan cheese
- 40g unsalted butter, melted
- 3 cloves garlic, minced
- 1 tablespoon lemon juice
- 1 teaspoon dried parsley
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ teaspoon paprika
- 1 tablespoon olive oil
Tip: For the best value, buy frozen cod fillets in bulk — they’re often half the price of fresh and work perfectly here once thawed overnight in the fridge.
How to Make Garlic Parmesan Baked Cod
- Preheat your oven to 200°C (400°F). While it heats, line a 9×13 inch baking dish with aluminium foil and brush lightly with olive oil — you’ll hear a faint sizzle as the oil meets the warm dish.
- Pat the cod fillets completely dry using kitchen paper. You want them dry to the touch, with no visible moisture; this ensures the topping clings properly and the fish doesn’t steam.
- In a small mixing bowl, combine the melted butter, minced garlic, lemon juice, dried parsley, salt, pepper, and paprika. Stir until the mixture is uniform — it should smell fragrant and look like a glossy, golden sauce.
- Arrange the cod fillets in the prepared dish in a single layer, leaving a small gap between each piece. Spoon the butter mixture evenly over the fish, using a brush to coat every surface until the fillets glisten.
- Sprinkle the grated Parmesan over the top, pressing gently so it adheres. The cheese should form a thick, even crust — you’ll see it clump slightly as you pat it down.
- Bake uncovered for 15 to 18 minutes. At the 15-minute mark, check for doneness: the cod should flake easily with a fork, the Parmesan crust will be deep golden brown, and the edges of the fillets will look slightly crispy. If you want a darker crust, switch to the grill for the final 2 minutes — watch closely so it doesn’t burn.
- Remove from the oven and let rest for 5 minutes. During this time, the juices redistribute, and the fish firms up slightly. You’ll notice the aroma of garlic and butter filling your kitchen — that’s your cue it’s ready.
Tips From My Kitchen
- Pat the fish dry religiously: Moisture is the enemy of a good crust. If the fillets are wet, the Parmesan mixture slides off and you end up with soggy fish. Spend an extra thirty seconds blotting them — it makes all the difference.
- Use freshly grated Parmesan: Pre-shredded cheese contains anti-caking agents that prevent melting and browning. Grate your own block, and you’ll get a crispier, more flavourful topping that clings to the cod.
- Don’t skip the rest time: Five minutes off the heat allows the fish to finish cooking gently and the butter mixture to set. If you cut into it immediately, the juices run out and the texture turns mushy.
- Double the batch for meal prep: This recipe scales perfectly. Cook two trays at once (rotate them halfway), then portion into airtight containers. It saves time and keeps your weekly lunches sorted for pennies per serving.
- Adjust garlic to your taste: Three cloves give a bold but not overpowering flavour. If you love garlic, add one more clove; if you prefer a milder touch, reduce to two. The butter base carries the flavour beautifully either way.
Equipment You’ll Need
- 9×13 inch baking dish
- Aluminium foil
- Mixing bowls
- Sharp knife
- Kitchen paper
- Pastry brush (optional but helpful)
Common Mistakes to Avoid
- Overcrowding the pan: If fillets are too close together, they steam instead of bake, resulting in a wet, pale crust. Always leave at least 2cm between pieces for air circulation and even browning.
- Wrong temperature: Baking at too low a temperature (below 190°C) makes the fish release moisture before the crust sets, leading to a soggy topping. Stick to 200°C — it’s the sweet spot for a golden finish.
- Skipping the rest time: Resting isn’t optional; it’s essential for texture. Without it, the cod breaks apart when you try to lift it, and the topping slides off. Give it those five minutes — you’ll thank yourself later.
What to Serve With Garlic Parmesan Baked Cod
- Steamed green beans tossed with lemon zest

Frequently Asked Questions
Can I use frozen cod without thawing it first?
I recommend thawing the cod completely in the fridge overnight before baking. Cooking from frozen increases the bake time unevenly, often leaving the centre undercooked while the topping burns. For consistent results, always thaw first.
How do I store and reheat leftovers?
Place cooled portions in an airtight container and refrigerate for up to three days. To reheat, warm them in a 180°C oven for 8 to 10 minutes — this preserves the crispy crust far better than a microwave, which tends to soften it.
Can I freeze this Garlic Parmesan Baked Cod?
Absolutely. Once baked and cooled, wrap each fillet individually in cling film, then place in a freezer-safe bag. Freeze for up to two months. Thaw overnight in the fridge and reheat in the oven for the best texture.
What other fish can I use instead of cod?
Haddock, pollock, or halibut work beautifully as substitutes because they share a similar flaky texture. Avoid oily fish like salmon, as the butter and Parmesan topping can become greasy rather than crisp.
Is this recipe suitable for a gluten-free diet?
Yes, this recipe contains no flour, breadcrumbs, or gluten-containing ingredients. Just double-check your Parmesan cheese label, as some pre-grated brands add anti-caking agents that may contain gluten — opt for a block of Parmesan to be safe.

Notes
For a darker, extra crispy crust, switch to broil (grill) for the final 2 minutes, watching closely to prevent burning. Patting the cod dry is essential for the topping to adhere properly.
