For the Whiskey Cream Sauce
- 1 tablespoon unsalted butter
- 2 garlic cloves, minced
- 2 shallots, finely chopped
- 1/2 cup Irish whiskey
- 1 cup heavy cream
- 1 cup beef stock
- 1 tablespoon whole-grain mustard
- Salt and freshly ground black pepper, to taste
For the Colcannon Potatoes
- 2 1/4 pounds Russet potatoes, peeled and diced
- 3 cups kale, chopped
- 1/2 cup green onions, sliced
- 1/3 cup unsalted butter
- 1 cup whole milk
- Salt and pepper, to taste
Instructions
Step 1: Marinate the Steaks
In a large resealable bag, combine the melted butter and Irish whiskey.
Add the steaks and coat thoroughly.
Refrigerate for at least 3 hours or overnight for maximum flavor.
Step 2: Prepare the Colcannon Potatoes
Place the diced potatoes in a large pot and cover with cold water.
Season with salt and bring to a boil.
Cook until fork-tender, about 15–20 minutes.
Meanwhile, melt butter in a skillet over medium heat.
Add the kale and cook until softened, about 3–4 minutes.
Stir in the green onions and remove from heat.
Drain the potatoes and return them to the pot.
Add the milk and mash until smooth and creamy.
Fold in the kale mixture and season with salt and pepper.
Cover and keep warm.
Step 3: Cook the Steaks
Remove the steaks from the refrigerator and allow them to sit at room temperature for 30 minutes.
Preheat the oven to 400°F (200°C).
Heat a cast-iron skillet over high heat.
Add a tablespoon of oil.
Pat the steaks dry and sear for 2–3 minutes per side until a deep golden crust forms.
Transfer the steaks to a baking sheet.
Finish cooking in the oven for 2–6 minutes, depending on desired doneness.
Step 4: Make the Whiskey Cream Sauce
Using the same skillet, reduce the heat to medium-low.
Add butter, shallots, and garlic.
Cook until softened and fragrant.
Carefully add the whiskey and allow it to reduce.
Pour in the beef stock, heavy cream, and mustard.
Season with salt and pepper.
Simmer gently for 8–10 minutes until the sauce thickens enough to coat the back of a spoon.
Step 5: Assemble and Serve
Spoon a generous serving of colcannon potatoes onto each plate.
Top with a perfectly cooked steak.
Drizzle generously with whiskey cream sauce.
Serve immediately while hot.
Tips for Success
- Let the steaks come to room temperature before cooking.
- Use a cast-iron skillet for the best crust.
