Ingredients
Cilantro Lime Butter
- ½ cup salted butter, room temperature (1 stick)
- 1 tbsp chopped fresh cilantro
- 1 tbsp fresh lime juice (from ½ lime)
- 2 tsp lime zest (from 1 lime)
- 1 tsp finely chopped green onion
- 1 tbsp garlic paste
Grilled Flank Steak
- 1 tsp kosher salt
- ½ tsp ground black pepper
- 1 tsp mustard powder
- 1 tbsp garlic paste
- 1 tbsp olive oil
- 2 lbs flank steak, at room temperature
- Canola oil for brushing grill or grill pan
Instructions
- Make Cilantro Lime Butter: Take the softened butter and place it in a medium bowl. Stir in the chopped fresh cilantro, fresh lime juice, lime zest, green onion, and garlic paste. Use a fork or spoon to mash and fully combine all ingredients into a smooth mixture.
- Chill the Butter: Transfer the butter mixture onto plastic wrap and form it into a log shape. Wrap tightly and refrigerate for at least 1 hour, or until firm, to allow flavors to meld and for easy slicing later.
- Prepare the Grill: Brush a grill or grill pan with canola oil and preheat it to high heat. Ensure the grill is HOT to achieve a good sear on the steak.
- Make the Steak Rub: In a small bowl, combine kosher salt, ground black pepper, garlic paste, olive oil, and mustard powder. Stir well to form an even paste. Rub this paste thoroughly on both sides of the flank steak.
- Grill the Steak: Place the seasoned flank steak on the hot grill. Cook for approximately 3-4 minutes per side for rare, or 6-8 minutes per side if you prefer well done. Adjust the cooking time based on your desired doneness by referring to a meat temperature chart.
- Rest and Slice the Steak: Remove the steak from the heat and let it rest briefly. Then slice the steak thinly against the grain to ensure tenderness.
- Serve with Cilantro Lime Butter: Slice the chilled cilantro lime butter and place slices over the warm steak to melt, enhancing the flavor with its zesty, creamy goodness.
Notes
- Allow the flank steak to come to room temperature before grilling for more even cooking.
- Resting the steak after grilling lets the juices redistribute, keeping the meat tender and juicy.
- Slice against the grain of the meat to maximize tenderness.
- You can prepare the cilantro lime butter in advance to save time on the day of grilling.
- Adjust lime juice and cilantro quantity in the butter to taste, based on your preference for acidity and herb flavor.
- Use a meat thermometer for precision: 130°F for medium-rare, 145°F for medium doneness.
