Shopping for White Fish Fillets

Fish may not be cheap to buy, but you can still find great quality fillets at a good price. When shopping for white fish fillets, your best bet is to use a flaky fish such as Cod and Snapper or on the cheaper end, Perch or Bass fillets. In fact, this recipe has been passed down to me by my brother, who is a chef by trade, and he personally uses Perch or Bass as he finds it cooks perfectly and the light flavour, allows the sauce to shine.

If however, you prefer an Australian fish, I have also cooked this recipe using Barramundi fillets, which is a sweet and slightly stronger flavoured fillet, and it has also turned out deliciously perfect.

Watch How To Make It

How do you make Lemon and Garlic Butter Fish

  1. Pre-heat oven: First begin by pre-heating the oven and preparing all the ingredients needed, including the fish, butter, minced garlic, thyme leaves, lemon juice, and seasoning.

  2. Place fish into baking tray: Pat dry the fish and place it into a baking tray that has been lined with baking paper. This makes the cleaning-up process so much easier!

  3. Melt the butter and combine the garlic, lemon, and thyme: Next in a small pan melt the butter and then reduce the heat to add the garlic and thyme. Once fragrant, turn off the heat and add the lemon juice.

  4. Pour over the fish: Pour the lemon and garlic butter sauce over the fish. Using tongs, turn the fish over to dip and coat all sides with the butter sauce. Season generously.

  5. Bake: Place into the oven for 15 minutes and in the meantime, steam rice, and vegetables or make a salad.

  6. Serve: Remove from oven and serve! It's that simple.

Lemon and Garlic Butter Baked Fish

Serves 4

Prep 5 minutes

Cook 15 minutes


Baked Fish:

4 White Fish Fillets* (approximately 180g each fillet)

2 tablespoons butter, dairy-free optional

1 tablespoon freshly minced garlic

1 tablespoon fresh thyme leaves

¼ cup fresh lemon juice

Sea salt and freshly ground pepper

To Serve:

Steamed Rice or Quinoa

Rocket or Green Salad


1. Preheat the oven to 200°C fan forced / 220°C conventional oven / 425°F. Line a baking dish with baking paper.

2. Melt the butter in a small frying pan and then add the garlic, thyme, and lemon juice. Combine well.

3. Place fish fillets into a baking dish and pour lemon garlic sauce over the fillets. Using tongs turn fillets over to coat both sides. Season with sea salt and pepper (optional to add a thin slice of lemon on each fillet).

4. Place in the oven and bake for 15 minutes or until cooked through. In the meantime, prepare a side dish of your choice.

5. Remove from oven and serve hot. Garnish with fresh parsley leaves.

*Personal preference for fish choice is Barramundi fillets; however, Perch fillets or Bass fillets are perfect to use. Keep in mind, if you use Barramundi, they are thicker and may need an extra 3 minutes of cooking time.
