Pistachio Crusted Halibut with Blood Orange Beurre Blanc Tips, FAQ & printable recipe

Tips for success

For an even more intense flavor, toast the shelled pistachios in a dry skillet for two minutes before pulsing them. This step deepens the nutty aroma and enhances the crunch of the final crust.

Allow the nuts to cool completely before processing them to ensure they stay crunchy and do not release their natural oils prematurely.

If you find the sauce is not thickening as expected, ensure the blood orange juice has reduced sufficiently before adding the butter. The reduction process is key to concentrating the sugars and acids in the juice.

If the sauce still appears too thin, continue to simmer it for another minute on low heat before beginning the butter incorporation process.

Variations

• Almond and Lime Crust: Replace the pistachios with toasted slivered almonds and use lime zest instead of lemon. This variation offers a slightly more delicate nut flavor and a sharper, more tropical acidity that works beautifully with the blood orange sauce.
• Walnut and Herb Crust: Use finely chopped walnuts mixed with fresh rosemary and thyme for an earthier, more robust crust. This version pairs exceptionally well with the citrus sauce, creating a sophisticated profile that is perfect for a more formal dinner setting.

Storage and make-ahead

Fridge

Store in the refrigerator in an airtight container for up to 2 days.

Reheat

Reheat the fish in a 300°F oven for 5 to 8 minutes until warmed through. The sauce should be gently warmed in a small saucepan over low heat.

If you have leftovers, allow the fish to cool to room temperature for no more than two hours before placing it in an airtight container. Keep the sauce in a separate, smaller container to prevent it from soaking into the crust, which will cause it to lose its crunch. Store both in the refrigerator for up to two days.

You can prepare the pistachio crust mixture up to one day in advance and store it in an airtight container in the refrigerator. The blood orange juice can also be reduced with the shallots ahead of time; simply keep the mixture in the fridge and reheat gently before whisking in the cold butter just before serving.

Serving ideas

To serve, place a single halibut fillet in the center of each plate, ensuring the crust is facing upward. Drizzle the warm blood orange beurre blanc around the base of the fish, rather than directly over the crust, to preserve the crunch.

Garnish with a few fresh parsley leaves or a thin wedge of blood orange to highlight the vibrant colors of the dish.

This dish pairs beautifully with simple sides that do not compete with the delicate flavor of the halibut. Consider serving it with steamed asparagus, roasted baby potatoes, or a light fennel and arugula salad.

The goal is to provide a refreshing, balanced accompaniment that allows the nutty, buttery, and citrusy flavors of the main course to remain the star of the meal.

Pistachio Crusted Halibut with Blood Orange Beurre Blanc

Prep 10 minCook 10 minTotal 20 minServes 4

Ingredients

• 1 cup shelled roasted pistachios
• 2 tbsp fresh parsley, chopped
• 1 tsp lemon zest
• 2 tbsp olive oil
• 4 halibut fillets (6 ounces each)
• 2 tbsp Dijon mustard
• 1/2 cup blood orange juice
• 1 tbsp shallots, minced
• 1 stick cold butter, cubed

Instructions

1. In a food processor, pulse the shelled roasted pistachios, fresh parsley, lemon zest, and two tablespoons of olive oil until the mixture resembles a coarse, vibrant green meal. Be careful not to over-process, as this will turn the nuts into a paste rather than a crunchy topping. Transfer the mixture to a shallow bowl for easy application.
2. Pat the four halibut fillets dry with paper towels to ensure the mustard adheres well. Using a pastry brush, coat the top of each fillet evenly with the Dijon mustard. Firmly press the pistachio mixture onto the mustard-coated side of each fillet, ensuring a thick, even layer that covers the entire surface.
3. Place the crusted halibut in a skillet and roast in a 400°F oven for approximately 8 minutes, or until the fish reaches an internal temperature of 145°F (63°C) and flakes easily with a fork. Meanwhile, in a small saucepan, simmer the blood orange juice and minced shallots until reduced by half. Remove from heat and whisk in the cold butter one cube at a time until the sauce is velvety and emulsified.
