Tender and juicy London broil with a cilantro parsley chimichurri sauce. So easy to make and full of flavor!
I wanted to experiment with London broil since I had never cooked with it before. The first time I had London broil was many moons ago at my best friend's house. Her dad made it on a regular basis.
Since the London broil was on sale at the grocery store, I decided to give it a go.
I paired it with a chimichurri sauce because my garden is full of parsley, cilantro, and oregano and I needed to find a way to use it up!
Although London broil is typically broiled, I grilled it for a smoky flavor and char.
This recipe also works well with flank steak.
Cilantro Chimichurri Sauce Ingredients & Substitutions
This sauce is super flavorful and made with fresh ingredients. A couple of substitutions can be made:
- More parsley instead of cilantro.
- Shallot instead of red onion.
- Apple cider vinegar or white wine vinegar instead of red wine vinegar.
- Finely chop parsley, cilantro, oregano, garlic and red onion. Mix in remaining sauce ingredients until just combined. If using a food processor, pulse until the herbs are chopped and be careful not to over process. The sauce should be chunky.
- Cover the steak with half of the chimichurri and marinade for 2 hours or overnight.
- Bring the steak to room temperature for 30 minutes. Grill the steak on medium high heat for 6-8 minutes on each side or until desired doneness. Cover and let it rest for 15 minutes.
- Cut the steak into thin slices against the grain and serve with chimichurri sauce.
Tips for Perfect Steak
- Let the steak come to room temperature for 30 minutes before cooking.
- Use a meat thermometer to ensure you reach your desired doneness and prevent overcooking the steak. The timing will depend on the thickness. I cooked a one inch London broil to 120°F as the temperature continues to rise as the steak rests.
- Let it rest for 15 minutes to let the juices redistribute.
- Slice thin slices against the grain for a tender steak.
