Ingredients

For the Steak

  • 1 lb Sirloin Steak – A quality cut is essential for rich flavor and tenderness.
  • 1/2 cup Irish Whiskey (e.g., Jameson) – Adds depth and smokiness.
  • 2 tbsp Butter – Brings richness and enhances the marinade.

For the Cream Sauce

  • 2 tbsp Shallots – Provides a mild onion aroma; substitute onions if needed.
  • 1 cup Cream – Use heavy cream for a luxurious sauce.

For the Colcannon

  • 2 cups Potatoes (Russets preferred) – For mashing and creaminess.
  • 1 cup Kale – A heartier twist; spinach can also be a substitute.

Seasoning

  • Salt, to taste – Essential for enhancing flavor.
  • Pepper, to taste – Essential for enhancing flavor.

Instructions

  1. Marinate the Steak: In a bowl, combine melted butter and Irish whiskey. Immerse the sirloin steak fully in this mixture and cover. Refrigerate and let it marinate for at least 3 hours to absorb the flavors and tenderize the meat.
  2. Sear the Steak: Preheat a cast iron pan over medium-high heat until hot. Remove the steak from the marinade, allowing excess liquid to drip off. Sear the steak in the pan for about 3-4 minutes on each side until a golden-brown crust forms, locking in juices.
  3. Bake the Steak: Preheat your oven to 350°F (175°C). Transfer the seared steak to an oven-safe dish or leave in the cast iron pan if oven-safe. Bake for approximately 10 minutes or until desired doneness is reached (medium rare to medium preferred).
  4. Prepare Colcannon: While the steak is baking, boil the potatoes in salted water until tender (about 15-20 minutes). Drain and mash them. Lightly sauté the kale until wilted, then fold it into the mashed potatoes. Season with salt and pepper to taste for a creamy, flavorful side.
  5. Make the Whiskey Cream Sauce: In the same cast iron pan used for searing, reduce heat to medium. Sauté the shallots until translucent and fragrant, about 2-3 minutes. Deglaze the pan with a splash of Irish whiskey, scraping up browned bits. Stir in the heavy cream and simmer the sauce until it thickens to a creamy consistency, about 5 minutes.
  6. Serve: Place the baked steak on a plate atop a generous serving of colcannon. Drizzle the whiskey cream sauce over the steak and around the plate. Serve immediately for the best taste and texture.

Notes

  • Marinating overnight can enhance flavor further.
  • Rest steak for 5 minutes after baking to retain juices.
  • Use heavy cream for the best sauce texture.
  • Russet potatoes yield the creamiest colcannon; Yukon Gold can be a substitute.
  • Adjust whiskey quantity in sauce carefully to prevent overpowering alcohol flavor.
