See recipe card below for quantities.
Instructions
Clean and prepare the whole flounder
- To prepare the whole flounder, make sure it is gutted and cleaned and that the gills are removed. Your fishmonger may have done this already and you can ask them to clean it for you.
- With a pair of sharp kitchen scissors trim the tail and fins off the flounder.
- Then place the flour on a large dinner plate and season with a good pinch of salt and pepper.
- Dust both sides of the prepared flounder in the seasoned flour.
How to cook a whole flounder
- Preheat the oven to 180 °C (356 °F) fan bake.
- Heat a large oven-proof dish (see our notes about equipment) over medium-high heat. Add half the oil and a third of the butter. Let the butter foam and when it stops foaming add the fish head side down.
- Cook for 2-3 minutes until golden, then carefully turn the flounder over in the pan. Then place in the preheated oven for about 6 minutes. (Cooking time will vary depending on the size of the fish)
- Once cooked, remove from the oven and carefully turn the fish back over in the pan and allow to rest.
A note from the chef - use an instant-read food thermometer to check the cook of the fish. The internal temperature of cooked fish should reach 63°C (145°F) at its thickest part. The flesh should also be opaque and flake apart easily with a fork.
How to make the tomato, lemon and basil butter sauce
While the flounder is baking in the oven time to prepare your delicious sauce.
- Heat a pan on a medium-high heat. Add the cherry tomatoes and allow the skins to charr.
- Once charred add the remaining oil and a third of the butter. Add the chopped garlic and baby capers. Allow to fry for about a minute.
- Add the white wine bring to a boil and reduce the liquid slightly.
- Remove the sauce from the heat, and stir through the remaining third of the butter. Squeeze in the juice of half a lemon, tear up the basil leaves and add to the sauce and stir well.
To serve
- Place the rested whole baked flounder on a serving dish.
- Pour the tomato, lemon and basil sauce over the fish.

Wine pairings
When it comes to pairing wine with whole baked flounder, we recommend selecting a light and refreshing wine that won't overpower its subtle taste.
Try a crisp, dry white wine such as Sauvignon Blanc or Chardonnay, that will compliment the mild flavour of the fish. Or select a sparkling wine like Prosecco or Champagne which will cut through the richness of the fish and cleanse your palate between bites.
Equipment
For this recipe, you will need a large oven-proof pan. We recommend using a skillet or cast iron dish that is large enough to fit the whole flounder but also fits in your oven. Remember this recipe starts at the cooktop and finishes in the oven so select a dish that works for both.
A tip from the chef
Start the cooking process at the right temperature - For the perfect cook of the flounder, allow the butter to foam and then stop foaming before adding the fish to the pan. Once the butter has stopped foaming, it indicates that the water content of the butter has evaporated and the pan is at the perfect temperature for cooking the fish.
This whole baked flounder recipe is a simple and delicious way to enjoy whole fish. Follow our chef tips for cooking whole flounder to perfect and pair it with our lemon and herb sauce for deliciously balanced flavours.
