My niece Kara and I came up with this recipe for Roasted Barramundi with Tomato and Olive Relish after I discovered Barramundi at Costco, and when we first made it, this recipe was so good that Kara made it at home (and sent me the photos) before I managed to get it up on the blog!
This was the first time Kara or I had cooked or eaten Barramundi, and we both loved the flavor and texture of the fish. I first bought Barramundi to try it when I saw a promotion for it at Costco. Since then I’ve noticed Barramundi showing up on blogs, restaurant menus, and in stores a lot more. If you’re a Barramundi fan, let me know in the comments!

How to make Roasted Barramundi with Tomato and Olive Relish:
(Scroll down for complete printable recipe including nutritional information.)
- Australis Barramundi is the brand I got at Costco, and with a coupon a whole bag of fish pieces was about $12.00! (And for the record, I never accept money to write about products on this blog, and I bought the Barramundi myself!)
- I did think it was odd the way each piece of fish had a thin flap on the side, and I trimmed those ultra-thin pieces off and discarded them when I cooked it. (They would be perfect to save for fish stock, if you’re into making that.)
- I rubbed the fish on both sides with olive oil and seasoned it with my favorite Szeged Fish Rub (affiliate link). (Use any fish rub you like if you don’t have this brand.)
- Let the fish come to room temperature while you warm up the oven (or toaster oven) and chop up equal amounts of cherry tomatoes, black olives, and green olives.
- You’ll also need a tablespoon or so of lemon zest, a couple of tablespoons of chopped parsley, and 2 tablespoons of fresh-squeezed lemon juice. (Zest the lemon first and then squeeze the juice. Just freeze the extra lemon juice if you have some.)
- Mix the chopped tomato, chopped black olives, chopped green olives, lemon zest, chopped parsley, lemon juice, and a tablespoon of olive oil to make the relish. Season the relish with a tiny bit of salt and fresh-ground black pepper. (If you don’t like some of those ingredients, feel free to improvise with what appeals to you.)
- Roast the fish about 10-12 minutes, or until it’s barely firm to the touch.
- Serve Roasted Barramundi hot, with a generous serving of tomato and olive relish spooned over.
More Tasty Ideas with Fish:
- 2 fillets Barramundi, about 5-6 oz. each (see notes)
- 2 tsp. olive oil, for rubbing fish
- 2 tsp. Szeged Fish Rub, for rubbing fish (see notes)
- 1/4 cup finely chopped cherry tomatoes
- 1/4 cup finely chopped black olives
- 1/4 cup finely chopped green olives
- 1 T lemon zest
- 2 T fresh-squeezed lemon juice (see notes)
- 2 T finely chopped fresh parsley
- 1 T olive oil
- salt and fresh ground black pepper to taste (I didn’t use much of either)
- Let fish thaw overnight or all day in the refrigerator (or in a pinch you can thaw in cold water, but thawing in the fridge is best.)
- If your fillets have a flap of very thin fish on the side, I would trim that off because it will get overcooked by the time the thicker parts are done. (Or cook the thin pieces separately and take them out of the oven as soon as they’re done.)
- Turn on the oven or toaster oven to 400F/200C to pre-heat.
- Rub both sides of the fish with olive oil and sprinkle with Szeged Fish Rub (affiliate link), rubbing it into the fish, and put fish on a roasting sheet. Let the fish come to room temperature while the oven heats and while you prepare the relish.
- Finely chop the cherry tomatoes, black olives, and green olives.
- Zest the lemon and then squeeze the juice and measure out 2 tablespoons lemon juice. (Just freeze the extra lemon juice if you have some.)
- Chops 2 tablespoons of flat or curly parsley.
- Stir together the tomatoes, black olives, green olives, lemon zest, lemon juice and olive oil and season the relish with a tiny amount of salt and fresh-ground black pepper. (I used just a tiny bit of salt and pepper.)
- When the fish is room temperature, put it into the oven or toaster oven and roast 10-12 minutes, or just until it’s barely firm to the touch. Serve hot, with a generous serving of the tomato and olive relish spooned over.
