Catfish Fillets in White Wine and Mushroom Sauce

The aroma of white wine simmering with earthy mushrooms always transports me back to my first apprenticeship in Lyon, France. Our “poisson du jour” was often a simple, yet elegant preparation, highlighting the freshness of the local catch. This recipe reminds me of those early days, the hustle of the kitchen, and the satisfaction of creating something truly delicious from humble ingredients. Though we used local river fish then, the principles remain the same: quality ingredients, careful technique, and a touch of love make all the difference.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 20 minutes
• Total Time: 35 minutes
• Servings: 6
• Dietary Type: Pescatarian

Ingredients

• 6 catfish fillets (about 2 lbs)
• 5 tablespoons butter, divided
• 1/2 cup dry white wine
• 8 ounces mushrooms, thinly sliced
• Salt and pepper, to taste
• 2 tablespoons flour
• 1/2 cup milk
• 1/2 lemon, juice of
• 2 tablespoons Parmesan cheese, freshly grated
• 2 tablespoons parsley, finely chopped

Equipment Needed

• Baking dish (large enough to hold the fillets in one layer)
• Saucepan
• Whisk

Instructions

1. Preheat your oven to 400°F (200°C).
2. Wash the catfish fillets and pat them completely dry with paper towels. This step is crucial for achieving a nice sear and preventing the fish from steaming.
3. Take your baking dish and rub the bottom with 1 tablespoon of the butter. Ensure the entire surface is lightly coated to prevent sticking.
4. Arrange the catfish fillets in the baking dish in a single layer. Avoid overcrowding, as this can lead to uneven cooking.
5. Pour the dry white wine evenly over the fish fillets. The wine will infuse the fish with flavor and help keep it moist during baking.
6. Scatter the thinly sliced mushrooms over the fish. Distribute them evenly for consistent flavor in each bite.
7. Season generously with salt and pepper, to taste. Don’t be shy with the seasoning; it’s essential for bringing out the flavors of the fish and mushrooms.
8. Place the baking dish in the preheated oven and bake for 10 minutes.
9. While the fish is baking, prepare the sauce. In a saucepan, melt the remaining 4 tablespoons of butter over medium heat.
10. Add the flour to the melted butter and immediately use a whisk to blend completely. This creates a roux, the base for your white sauce. Cook for about 1 minute, stirring constantly, to cook out the raw flour taste. Be careful not to brown it.
11. Gradually add the milk to the roux, whisking continuously to prevent lumps from forming. Cook, whisking all the while, until the sauce has thickened and is smooth. This should happen pretty quickly.
12. After the catfish fillets have baked for 10 minutes, carefully remove the pan from the oven.
13. Very carefully pour the liquid from the baking dish into the white sauce in the saucepan. Try to get as much of the liquid as possible, but don’t worry about getting every last drop. This liquid is packed with flavor and will enhance the sauce.
14. Bring the contents of the saucepan once again to a gentle boil over medium heat, then reduce the heat to low and simmer for 5 minutes, stirring as needed to prevent sticking. I find that whisking almost constantly helps to keep the sauce smooth and prevents burning.
15. After simmering for 5 minutes, remove the saucepan from the heat.
16. Stir in the lemon juice. The acidity of the lemon juice will brighten the sauce and balance the richness of the butter and cream.
17. Pour the sauce evenly over the catfish fillets in the baking dish.
18. Return the fish to the oven and bake for an additional 10 minutes, or until the fish is cooked through and flakes easily with a fork. The internal temperature should reach 145°F (63°C).
19. To serve, sprinkle the top of each serving with freshly grated Parmesan cheese and finely chopped parsley.

Expert Tips & Tricks

• Don’t Overcook the Fish: Catfish can dry out easily if overcooked. Watch it closely during the final 10 minutes of baking. The fish is done when it flakes easily with a fork.
• Enhance the Mushroom Flavor: Sauté the mushrooms in a separate pan with a little butter and garlic before adding them to the baking dish for a richer, more intense mushroom flavor.
• Make-Ahead Tip: You can prepare the white sauce ahead of time and store it in the refrigerator for up to 24 hours. Reheat gently before pouring it over the fish.
• Thickening the Sauce: If your sauce is too thin, whisk in a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) while it’s simmering.
• Salt your fish! This is important, as it brings out the flavor of the fish!

Serving & Storage Suggestions

Serve the Catfish Fillets in White Wine and Mushroom Sauce immediately after baking for the best flavor and texture. It pairs beautifully with steamed asparagus, roasted potatoes, or a simple green salad.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently in a saucepan over low heat or in the microwave. The sauce may thicken upon refrigeration, so you may need to add a splash of milk or white wine when reheating. Freezing is not recommended as the sauce may separate upon thawing.
