How to defrost fish?
Overnight Refrigerator Method
The safest way is to defrost the fish overnight in the fridge by transferring the fish from the freezer to the refrigerator and letting it thaw out overnight. It is recommended that the fish be kept in individually sealed packaging to avoid any leaking. When ready to cook, open the packaging, rinse under cold water, pat dry with paper towels, and it's ready for use.
Quick Method
But if pressed for time, another option is to submerge the individually sealed fish packets in cold water in a shallow dish. It should take about 20 to 30 minutes to thaw out, check halfway, and change out the cold water if needed. When ready to cook, remove from packaging, rinse in cold water, pat dry. If defrosting via the quick method, use the fish immediately. I don't recommend submerging just the fish without its packaging in the water as it can absorb too much liquid.
How to cook barramundi?
Barramundi is a versatile fish that can be prepared in various ways, including baking, steaming, poaching, grilling, pan frying, or cooking in parchment paper (en papillote). My preferred method is pan-searing - it's quick and easy and creates a delicious golden crust while keeping the interior moist and flaky. An added bonus is that you can toss vegetables like broccoli, asparagus, or string beans into the same pan to complete the meal. This one-pan approach saves time and dishes!
And don't worry about stinking up the kitchen. It is a mild fish, so it will not have a strong aroma when it hits the pan.
Ingredients
This entire recipe comes together with just 5 ingredients, including the side of vegetables.
- Barramundi Fillets (I like the Australis Brand. It can be found in the supermarket's freezer section. )
- Lemon
- Butter (I prefer to use Kerrygold Salted)
- Fresh Herbs like parsley, cilantro, or dill
- Green beans or asparagus or broccoli
See the recipe card for quantities.

Step by Step
- Ensure the fish is fully thawed. Pat dry barramundi fillets and season with salt and pepper, season with salt and pepper, or use a citrus salt seasoning like Borsari Citrus Salt.
- Heat a large skillet over medium-high heat. Add avocado or olive oil, just enough to coat the pan.
- Once the pan is hot, add the fish fillets to the pan and cook undisturbed for 3 to 4 minutes. Gently flip with a fish spatula. If the fish is sticking and not easily released from the pan, give it another minute or so to cook.
- This step goes quickly, so have all your ingredients, like butter, lemon juice, and a small spoon ready. After 2 minutes on the second side, lower the heat to medium-low. Add butter and lemon juice to the pan. Tilt the pan to one side, and spoon the melting butter/lemon mixture over the fish repeatedly until fully coated.
- Transfer fish to a plate and garnish with fresh herbs like cilantro or dill.
- Optional: To make it a complete meal, prepare a quick vegetable side. Add green beans to the hot pan, mixing with the remaining lemon butter sauce. Season with salt and garlic powder (or garlic salt), then cook for 3-4 minutes or until the green beans are vibrant green. If needed, add a sliver of butter and the other half of the lemon for extra flavor. Serve the greens alongside the fish.
Recipe Tips
- Pat the fish dry before cooking for a crispy exterior.
- Have all the ingredients ready before you start cooking, as the recipe comes together quickly.
- Use a fish spatula for easier flipping
- Dont overcook - the fish should be just opaque in the center.
- For a quick defrost - submerge sealed fish packets in cold water for about 20 minutes. If unsealed, place the fish in a plastic bag first to prevent water absorption.
Choosing the right pan
The pan you use can have a significant impact on your results. I recommend using the one you are most comfortable with. If you are a novice cook, use a non-stick pan for easier handling. If you are more comfortable in the kitchen, a stainless steel pan or a cast-iron skillet works well in this recipe. whichever pan you choose, just make sure the pan is hot before adding the fish. This helps achieve a good sear and prevents sticking.
In addition, choose a skillet or pan with a large surface area bottom that can fit the fish fillets comfortably.
What to serve with Barramundi
Barramundi can be served with vegetables like green beans, asparagus, broccoli, or grilled romaine lettuce. But it is also delicious with mashed potatoes, buckwheat groats, or rice. Or, for a lighter meal, pair it up with a salad, like this refreshing fennel salad with cucumbers or a mango salsa.

Barramundi fillet in lemon butter sauce
Ingredients
Fish
- 2 Barramundi fillets, fresh or defrosted
- generous pinch of salt
- 2 teaspoon avocado oil or olive oil
- ½ lemon , juiced
- 1 tablespoon butter
- 1 tablespoon cilantro or dill, chopped
Green Beans
- salt and pepper to taste
- 1 teaspoon granulated garlic or garlic powder
- ½ lb green beans or haricots verts, trimmed
- ½ lemon (optional), juiced
- ½ tablespoon butter (optional)
Instructions
To cook fish
- Pat the fish dry with paper towels to remove moisture and season with salt on both sides.
- Heat a skillet with a large surface bottom over medium-high heat. (Use a non-stick, a cast-iron skillet, or stainless steel pan, whichever you feel most confident using.) Add avocado or olive oil, about 2 to 3 teaspoons, or enough just to coat the pan.
- Once the pan is hot, place the fish fillets in the pan and cook without touching or moving them for about 3 to 4 minutes. Using a fish spatula, gently flip the fillets to the other side. If the fish is sticking to the pan, give it another minute to cook. In general, fish is ready to flip when it easily separates from the pan.
- Cook on the other side for about 2 minutes. Add to the pan butter and juice of half a lemon. Tilt the pan to one side, and using a spoon, spoon the melting butter and lemon mixture over the fish, repeating several times. Transfer fish to a serving plate and sprinkle with fresh cilantro or dill.
To cook green beans
- In the same hot pan, add green beans. Using a spatula, mix the green beans with the butter and lemon mixture still coating the pan, season with garlic salt or salt and garlic powder. If the green beans appear dry or not coated well, add an optional sliver of butter and ½ lemon to the pan. Cook for about 3 to 4 minutes or until the beans are bright green. Remove to a serving plate and enjoy!
Notes
- Make sure the fish is fully thawed.
- Pat the fish dry before cooking for a crispy exterior.
- Ensure the pan is hot before adding the fish.
- Have all ingredients ready to go before you start cooking, as the recipe comes together quickly.
- You can substitute green beans with asparagus, snow peas, or broccolini.
