I'm always looking for another new way to cook this delicious fish. We've tried
Swai Chowder and
Baked Swai Tacos, but could we make this into an elegant dish suitable for guests? With a little research we found just the right recipe, it just needed a little tweeking!
This recipe was originally prepared using Sole fillets and lots of butter, but we found the Swai fillets are just as good if not better. Another change was to reduce the amount of butter in the sauce by half, and use a little cornstarch and water to thicken, if needed.
The easy Citrus Beurre Blanc sauce can be used on many dishes. For the citrus juice you can substitute orange, but the tangerine is a real treat.
1 1/2 TB Unsalted Butter, melted
2 TB Minced Shallots
4 - 6 Strips Lime or Tangerine Zest
1 lb Fresh Asparagus Spears
4 - 5 Swai Fillets (or use Flounder) about 5 oz each
1/4 Cup Water
1/4 cup Dry White Wine
1/2 cup Fresh Tangerine Juice
1 TB Finely Minced Shallot
3 TB Cold Unsalted Butter
1/4 tsp Salt
Pinch of Cayenne
1/2 tsp Lime or Lemon Juice
** Optional: 1 TB Cornstarch blended with 1 tsp cold water can be used to thicken sauce, if needed
Place oven rack in the middle position and preheat oven to 450.
To prepare pan: Using a 13 x 9 inch baking dish, brush bottom of pan with melted butter and sprinkle the minced shallots and the zest into the butter.
Trim asparagus to about 6 inches, cutting away the tough ends. Using a potato peeler, peel the spears from about 2 inches below the tip. Using a large pot, heat about 2 inches of lightly salted water. When the water boils, add asparagus and blanch for 3 - 5 minutes (depending on thickness) until spears are tender but not fully cooked. Remove asparagus from the pan and quickly rinse under cold water to stop the cooking process. Set aside to cool until needed.
Lay fillets on a cutting board and season with salt and pepper. Next place 4 - 5 asparagus spears across each fillet and roll up to create a bundle. Place bundles in baking dish, add the water and wine to the bottom, cover tightly with foil and bake for about 20 minutes until fish is cooked through.
Make Beurre Blanc Sauce:
In a heavy 2-quart saucepan, boil the tangerine juice over medium heat until reduced to 2 tablespoons, about 5 minutes. Reduce heat to medium-low, then whisk in 1 TB butter. Add the remaining butter, 1 TB at a time, whisking constantly, and occasionally pulling the pan off of the heat to cool the mixture slightly. This will prevent the sauce from cracking. If sauce is a bit too thin, increase the heat and slowly add the cornstarch and water mixture while whisking. Remove the sauce from the heat and stir in salt, cayenne and lime or lemon juice.
Transfer fish with a slotted spatula to a platter and reserve pan juices. Cover fish with foil. Discard the zest and pour the pan juices into a 10-inch skillet. Bring the juices to a boil over medium-high heat until reduced to about 2 tablespoons, about 2-3 minutes. Gradually whisk in the Beurre Blanc and stir to the desired consistency.
Place one fish/asparagus bundle on each plate and top with a spoonful of the Beurre Blanc, plus extra sauce on the plate for dipping. Serve with Jasmine Rice.
Enjoy!
