Ingredients
For the Steaks
-
2 flank steaks (1–1½ inches thick, about 1½ lb each)
-
2 tbsp olive oil
-
1½ tsp kosher salt
-
1 tsp freshly ground black pepper
For the Irish Herb Marinade
-
¼ cup olive oil
-
2 tbsp Irish whiskey (optional, adds depth)
-
2 cloves garlic, minced
-
1 tbsp fresh parsley, finely chopped
-
1 tsp fresh thyme leaves
-
1 tsp fresh rosemary, chopped
-
1 tsp lemon zest
-
½ tsp crushed red pepper flakes (optional)
Step-by-Step Instructions
1. Prepare the Marinade
-
In a small bowl, whisk together olive oil, whiskey, garlic, parsley, thyme, rosemary, lemon zest, and red pepper flakes.
-
Taste and adjust seasonings if desired.
2. Marinate the Flank Steaks
-
Place steaks in a shallow dish or zip-top bag.
-
Pour the Irish herb marinade over the steaks, making sure they are evenly coated.
-
Cover and refrigerate at least 2–4 hours, preferably overnight for maximum flavor and tenderness.
🔑 Longer marination allows the herbs and citrus to penetrate the lean meat.
3. Preheat the Grill
-
Heat grill to high heat (450–500°F / 230–260°C).
-
Oil the grates lightly to prevent sticking.
4. Grill the Flank Steaks
-
Remove steaks from the marinade and pat dry to achieve a proper sear.
-
Grill 4–6 minutes per side for medium-rare, depending on thickness.
-
Optional: Rotate 45° halfway through each side for professional crosshatch marks.
-
Use an instant-read thermometer:
-
Medium-rare: 130–135°F (54–57°C)
-
Medium: 140–145°F (60–63°C)
-
5. Rest and Slice
-
Transfer steaks to a cutting board and tent loosely with foil for 5–10 minutes.
-
Slice thinly against the grain for maximum tenderness.
6. Serve
-
Serve with Irish-inspired sides such as mashed potatoes, roasted root vegetables, or buttered green beans.
-
Optional: Garnish with extra parsley or a squeeze of lemon juice for brightness.
