Catfish Courtbouillon
A rich, spicy tomato-based stew from Louisiana, featuring tender catfish fillets simmered in a deeply seasoned roux-thickened gravy. The holy trinity of onion, celery, and bell pepper melds with Creole spices, creating layers of flavor that develop as the pot bubbles low and slow. Perfect over steamed rice for a comforting bayou classic.

- prep
Season the catfish.
Pat the catfish chunks dry with paper towels. Sprinkle lightly with salt and pepper, set aside.
TIPKeeping the fish dry helps it hold its shape when it hits the hot gravy later. - fry · ~20 min
Make the roux.
1.Heat vegetable oil in the pot over medium heat.2.Once shimmering, whisk in the flour slowly.3.Cook, stirring constantly, until the roux turns a deep reddish-brown (15-20 min).TIPA dark roux looks like milk chocolate. Don't walk away — constant stirring prevents burning, and burnt roux means starting over. - saute · ~9 min
Sweat the holy trinity.
1.Add chopped onion, celery, and bell pepper to the roux immediately.2.Stir and cook until softened (6-8 min).3.Add minced garlic and cook 1 minute more.TIPAdding the vegetables stops the roux from darkening further and locks in the color. - simmer · ~5 min
Build the gravy base.
1.Stir in the diced tomatoes and tomato paste, mixing well to combine.2.Pour in the water and add bay leaves, dried thyme, and cayenne.3.Season with the remaining salt and pepper.4.Bring to a gentle boil, then reduce heat to low. - simmer · ~30 min
Simmer the gravy until rich.
Cover partially and let the gravy bubble gently for 25-30 minutes, stirring occasionally. The tomatoes should break down and the sauce will thicken.
TIPIf the gravy gets too thick, add a splash of water. You want it to coat the back of a spoon. - simmer · ~10 min
Poach the catfish in the gravy.
1.Gently nestle the catfish chunks into the simmering gravy.2.Cover the pot and cook on low heat until the fish flakes easily with a fork (8-10 min).TIPDo not stir once the fish is in — catfish is delicate and will break apart. Spoon gravy over the top instead. - garnish · ~5 min
Finish and serve.
1.Remove the bay leaves.2.Drizzle lemon juice over the top and let it rest off heat for 5 minutes.3.Ladle into bowls over steamed rice and scatter with green onion and parsley.TIPA little acidity from the lemon brightens the whole dish. Taste and adjust salt right before serving.
What to keep in mind.
8 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the catfish very dry before seasoning to help it sear and stay intact in the gravy.
- 2Cook the roux to a deep reddish-brown color, about the shade of milk chocolate, for authentic flavor.
- 3Stir the roux constantly; burnt roux cannot be saved and will ruin the dish.
- 4Add the holy trinity immediately after the roux is ready to stop it from darkening further.
- 5Simmer the gravy until it coats the back of a spoon; add water if it becomes too thick.
- 6Nestle the catfish gently into the gravy and do not stir; spoon gravy over the fish instead.
- 7Let the courtbouillon rest off heat for 5 minutes after adding lemon juice to meld flavors.
- 8Leftover courtbouillon keeps well for 2 days in the fridge and tastes even better reheated.

Omit the fish and double the vegetables, adding 200 g of okra and 1 can of drained chickpeas for a hearty meat-free version.
low oilLow-oil
Make a dry roux by toasting flour in a dry pan, then whisk in half the oil to reduce fat while keeping the caramelized flavor.
