Vietnamese Poached Flounder in Tomato Sauce (Cá Sốt Cà Chua)
Tender flounder fillets gently poached in a bright, savory cherry tomato and fish sauce sauce. Ready in about 30 minutes.
Ingredients
- 16 oz flounder fillets Wild Alaska Sole; thawed if frozen
- 24 oz cherry tomatoes
- ½ head garlic minced
- 1 shallot sliced
- 3 tablespoon cooking oil
Seasoning
- 1½ tablespoon fish sauce
- 1 tablespoon sugar
- ½ tablespoon chicken powder
- ½ teaspoon salt
- ½ cup water
To garnish
- green onion sliced
- cilantro
- black pepper freshly cracked
Instructions
- Thaw the fish: If frozen, submerge the fillets in their vacuum-sealed bags in warm water. They should thaw in 20-30 minutes.
- Prep the fillets: Remove the fillets from the bags, gently clean, pat dry and halve them. Set aside.
- Sauté the aromatics: Heat 3 tablespoon cooking oil in a pan and sauté the garlic and shallot until fragrant.
- Build the sauce: Add the cherry tomatoes and sauté for a few minutes. Add the salt, sugar, water, fish sauce and chicken powder. Lower the heat to a simmer and let the tomatoes soften.
- Burst the tomatoes: Once softened, pop about half of the cherry tomatoes to help build the sauce. Leave the other half whole so they keep their shape.
- Poach the fish: Gently add the fillets and make sure they are submerged in the sauce. Cook for 6-7 minutes, or until just cooked through. Don't overcook, or the fillets will turn mushy. You want the pieces to stay intact.
- Garnish and serve: Top with sliced green onion, cilantro and freshly cracked black pepper. Serve with rice and vegetables.
Notes
Gentle handling: Flounder is delicate. Move the fillets as little as possible once they're in the sauce so they stay in whole pieces.
