Whiskey steak with creamy colcannon

This elegant Irish-inspired dinner combines succulent whiskey-marinated sirloin steaks, velvety smooth whiskey cream sauce, and buttery kale colcannon potatoes for an unforgettable meal. Each component builds upon traditional Irish flavors while elevating them to new heights. The steaks develop incredible tenderness and depth from their whiskey-butter marinade, while the luxurious sauce adds richness with every bite. Paired with the comforting colcannon – creamy mashed potatoes studded with vibrant kale and green onions – this meal strikes the perfect balance between rustic comfort food and sophisticated dining.

I was looking for a way to celebrate my Irish heritage beyond the typical corned beef and cabbage when I created this recipe. The first time I served it for a family gathering, my grandfather – who rarely offers compliments – took a bite, set down his fork, and declared it "properly Irish, but better than anything I had growing up." The combination of tender steak, whiskey-laced sauce, and buttery potatoes has since become our new tradition for St. Patrick's Day and special celebrations.

Essential Ingredients and Selection Tips

• Sirloin Steaks: Choose well-marbled, thick-cut steaks of equal size for consistent cooking. Quality matters here.
• Irish Whiskey: Jameson works beautifully, but any Irish whiskey will do. The distinct mellowness of Irish whiskey is key to the flavor profile.
• Kale: Curly kale holds its texture better than other varieties in the colcannon. Remove tough stems before chopping.
• Russet Potatoes: Their high starch content creates the fluffiest mashed potatoes. Choose potatoes of similar size for even cooking.
• Shallots: These provide a milder, more refined flavor than onions in the sauce. Don't substitute regular onions.

The quality of your whiskey makes a significant difference in this dish, though you needn't use your finest bottle. I've found that a mid-range Irish whiskey like Jameson offers the perfect balance of flavor without overwhelming the other ingredients.

Detailed Cooking Instructions

Step 1: Prepare The Tenderizing Marinade

Place 7 six-ounce sirloin steaks in a large ziplock bag. Combine 1 cup melted unsalted butter with 1/4 cup Irish whiskey and pour over the steaks. Seal the bag, removing as much air as possible, and turn several times to coat the steaks evenly. Refrigerate for at least 3 hours, preferably 6-8 hours, turning occasionally for maximum flavor penetration.

Step 2: Create The Perfect Colcannon

Peel and dice 2 1/4 pounds of russet potatoes into uniform pieces. Place in a large pot, cover with cold water, add a generous pinch of salt, and bring to a boil. Cook until easily pierced with a knife, about 15-20 minutes. Meanwhile, in a sauté pan over medium-low heat, melt 1/3 cup unsalted butter and add 3 cups chopped curly kale. Cook for 3-4 minutes until wilted but still vibrant, then add 1/2 cup diced green onions and remove from heat. Drain the potatoes thoroughly, return them to the pot, add 1 cup warm whole milk, and mash to your preferred consistency. Fold in the kale mixture, season generously with salt and pepper, then cover to keep warm.

Step 3: Master The Steak Sear

Remove marinated steaks from the refrigerator 30 minutes before cooking to take the chill off. Preheat oven to 400°F and heat a cast iron pan over high heat for 3-4 minutes until smoking hot. Add 1 tablespoon of high-heat oil to the pan. Pat the steaks dry with paper towels (crucial for a good sear), then sear for 2-2 1/2 minutes on the first side until deeply caramelized. Flip and cook for 1-2 minutes on the second side. Transfer to a baking sheet and continue with remaining steaks. Place in the preheated oven to finish cooking to your desired doneness, about 2-6 minutes depending on thickness and preference.

Step 4: Create The Luxurious Whiskey Sauce

Return the steak pan to medium-low heat. Add 1 tablespoon unsalted butter, 2 minced garlic cloves, and 2 finely minced shallots. Cook for 1-2 minutes until softened but not browned. Turn off the heat before carefully adding 1/2 cup Irish whiskey (it may flame briefly). Return to low heat and cook until the whiskey is mostly evaporated. Add 1 cup heavy cream, 1 cup beef stock, and 1 tablespoon whole grain mustard. Season with salt and freshly cracked pepper. Simmer gently for 8-10 minutes until the sauce coats the back of a spoon, indicating it has reached the perfect consistency.

Step 5: Bring It All Together

Remove steaks from the oven and let rest for 5 minutes. Place a generous scoop of colcannon on each warmed plate, top with a steak, and drizzle with the whiskey cream sauce. Garnish with additional green onions or a sprinkle of fresh parsley if desired. Serve immediately while everything is hot.

I learned the importance of properly resting steaks the hard way. During my first attempt at this recipe, I was so eager to serve that I skipped the resting period. When I cut into the steaks, all those flavorful juices ran out onto the plate instead of redistributing throughout the meat. Now I always allow 5 minutes of resting time, which makes a remarkable difference in the final texture and juiciness.

Creating The Perfect Steak Crust

The signature crust on these steaks isn't just about appearances – it's a crucial flavor component created through the Maillard reaction. After extensive experimentation, I've discovered several key techniques. First, thoroughly patting the steaks dry after marinating is non-negotiable; any moisture on the surface creates steam instead of sear. Second, the cast iron pan must be preheated until it's smoking hot before adding oil and steak. When I rush this step, the difference is immediately noticeable in both color and flavor. Finally, resist the urge to move the steaks during searing – letting them develop that crust undisturbed makes all the difference. My father-in-law, a dedicated steak enthusiast, declared these "the best steaks he'd ever had outside a steakhouse" once I perfected this technique.

Mastering The Whiskey Cream Sauce

The velvety whiskey cream sauce is arguably the crown jewel of this dish, transforming great steaks into an unforgettable meal. The key to its success lies in proper reduction and temperature control. I've found that allowing the whiskey to reduce almost completely before adding the cream and stock creates the most complex flavor. Too much haste here results in a thinner sauce with harsh alcohol notes. Low, gentle heat during the final reduction prevents breaking or curdling while allowing the flavors to concentrate perfectly. For special occasions, I sometimes add 2 tablespoons of aged Irish whiskey off the heat just before serving for an extra layer of flavor. This sauce has become so popular in our household that I now make double batches – it's wonderful the next morning over scrambled eggs or as a dipping sauce for good bread.

Colcannon Variations Worth Trying

While this kale-based colcannon is delicious, I've experimented with several variations that honor the spirit of the dish while offering different flavor profiles. For a more traditional version, substitute an equal amount of finely shredded savoy cabbage for the kale. During spring celebrations, I sometimes add 1/4 cup of fresh chopped herbs like parsley, chives, and thyme to the mixture. For a heartier version that my husband particularly loves, I fold in 4 slices of crispy, crumbled bacon along with the kale. The most luxurious variation, reserved for very special occasions, incorporates 1/2 cup of crumbled Irish blue cheese, which melts beautifully into the warm potatoes. Each version complements the whiskey-infused steaks wonderfully while offering a slightly different experience.

Perfect Wine Pairings

While an Irish whiskey seems the natural pairing for this meal (and it is excellent), I've found that certain wines complement these flavors beautifully. A robust Cabernet Sauvignon stands up nicely to the richness of the steak and sauce, while a Syrah with peppery notes creates interesting counterpoints to the whiskey flavors. For white wine enthusiasts, a full-bodied, oaked Chardonnay has enough structure to work surprisingly well. When hosting a dinner party centered around this meal, I sometimes offer small pours of both wine and Irish whiskey, allowing guests to discover their preferred pairing. The conversations that ensue about flavor combinations add an extra dimension to the dining experience, making the meal not just delicious but memorable.

Frequently Asked Questions

→ Can I substitute the Irish whiskey with something else?

Yes, though it will change the authentic flavor profile. For an alcohol-free version, you can use apple juice mixed with a splash of apple cider vinegar and a drop of vanilla extract to mimic some of the whiskey's complexity. For an alcoholic alternative, bourbon can work well, though it will have a sweeter profile than Irish whiskey.

→ How do I know when my steaks are cooked to the right temperature?

For best results, use a meat thermometer. For medium-rare, cook to an internal temperature of 135°F (57°C); for medium, aim for 145°F (63°C); for medium-well, 150°F (66°C); and for well-done, 160°F (71°C). Remember that the temperature will rise slightly during resting, so you can remove the steaks when they're about 5°F below your target temperature.

→ Can I make any components of this dish ahead of time?

Yes! The colcannon can be made up to 2 days ahead and reheated with a splash of milk or cream. The steaks should be marinated for at least 3 hours, but you can extend this to overnight for deeper flavor. The whiskey cream sauce is best made fresh while the steaks are resting, but it can be made ahead and gently reheated (though it may need additional cream to thin it out).

→ Can I use cabbage instead of kale in the colcannon?

Absolutely! Traditional Irish colcannon is often made with cabbage. You can substitute an equal amount of finely shredded green cabbage or savoy cabbage for the kale. Cook it the same way, until wilted and tender.

→ What can I serve with this meal besides the colcannon?

While the colcannon is a perfect accompaniment, you could also add sautéed mushrooms, roasted root vegetables like carrots or parsnips, or a simple green salad with a light vinaigrette to balance the richness of the steak and sauce. A side of Irish soda bread would also be authentic and delicious.

→ Is it safe to cook with alcohol if there will be children at the table?

The alcohol in both the marinade and sauce will cook off during the cooking process, leaving only the flavor behind. After the 8-10 minutes of simmering the sauce, virtually all the alcohol will have evaporated, making it safe for everyone to enjoy, including children.
