Irish Whiskey Flat Iron Steak

There's something special about a perfectly grilled steak that brings everyone to the table. This Irish whiskey flat iron steak is a keto-friendly twist on a classic, with a marinade that adds depth without extra carbs. I love how the whiskey and soy sauce work together to tenderize the meat and create a savory crust.

Irish Whiskey Flat Iron Steak

Ingredients

  • /3 cup extra-virgin olive oil
  • tablespoons Irish whiskey
  • tablespoons soy sauce
  • tablespoon minced green onion
  • tablespoon minced garlic
  • tablespoon ground black pepper
  • tablespoon chopped fresh parsley
  • /2 teaspoon dried thyme
  • /8 teaspoon crushed dried rosemary
  • (8 ounce) flat iron steaks

Instructions

  1. Step 1

    I start by combining the olive oil, whiskey, soy sauce, green onion, garlic, pepper, parsley, thyme, and rosemary in a large sealable plastic bag. Give it a good shake to blend everything together. Then I lay the steaks in the bag, seal it tight, and massage the marinade into the meat. Pop it in the fridge for at least an hour, or up to eight for deeper flavor. When the craving hits, pull the steaks out, discard the used marinade, and let them sit on the counter until they reach room temperature—this helps them cook evenly. Heat your grill to medium-high and lightly oil the grates to prevent sticking. Grill the steaks for about 6 to 7 minutes per side, aiming for a nice char on the outside while the inside stays slightly pink. An instant-read thermometer is handy here

  2. Step 2

    °F gives you a perfect medium-rare. Once off the heat, tent the steaks loosely with foil and let them rest for 10 minutes—this step is crucial for juicy results. Slice against the grain and serve with your favorite keto sides.

Chef's Tip

For the best crust, pat the steaks dry before they hit the grill. I also swear by letting the meat rest on a warm plate—cold plates can suck the heat right out, leaving you with a lukewarm steak.

Storage Tips

Store leftover steak in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet over medium heat to maintain tenderness.

Variation Tips

Pair this steak with roasted asparagus or a crisp arugula salad dressed with lemon vinaigrette for a complete keto meal. For a different twist, swap the whiskey for bourbon or add a teaspoon of Dijon mustard to the marinade.
