Instructions
Let’s dive into the steps to create this decadent dish:
Crack the Peppercorns: Using a mortar and pestle or the back of a knife, coarsely crack the black peppercorns. You want them chunky for that signature crust.
Season the Swordfish: Pat the swordfish steaks dry and season generously with salt and cracked black pepper on both sides. Press the pepper into the fish to help it stick.
Sear to Perfection: Heat olive oil in a skillet over medium-high heat. Sear the swordfish for 3-4 minutes per side until golden brown and just cooked through. Remove from the pan and set aside.
Make the Butter Sauce: In the same pan, reduce the heat to medium. Add butter and minced garlic, letting it sizzle until fragrant.
Deglaze the Pan: Pour in the brandy or white wine, scraping up any browned bits for extra flavor. Let it simmer for a minute.
Finish the Sauce: Stir in the heavy cream (if using) and a squeeze of fresh lemon juice. Simmer until slightly thickened.
Serve & Enjoy: Pour the luscious sauce over the swordfish, garnish with fresh parsley, and serve immediately.
How to Serve Buttery Swordfish Au Poivre
- With Mashed Potatoes: The creamy texture pairs beautifully with the rich butter sauce.
- Over Roasted Vegetables: Serve with asparagus, Brussels sprouts, or carrots for a well-rounded meal.
- With a Light Salad: A crisp green salad with a lemon vinaigrette adds a refreshing contrast.
- Over Rice or Risotto: A bed of rice or creamy risotto soaks up the incredible sauce.

Additional Tips
Use Fresh Swordfish: For the best texture and flavor, get fresh, high-quality swordfish steaks.
Don’t Overcook: Swordfish can dry out quickly, so aim for a slightly pink center when cooking.
Let It Rest: Allow the fish to rest for a few minutes after searing to keep it juicy.
Control the Heat: If you prefer a milder spice, use a mix of black and white peppercorns.
Substitutions: If you don’t have brandy, swap it for white wine, chicken broth, or even a splash of balsamic vinegar.
