Juicy marinated Flank Steak is grilled to perfection and topped with zesty homemade Chimichurri sauce! This low-carb recipe is perfect for cookouts, parties, or a delicious weekend meal!
Combine the marinade ingredients in a large bowl or gallon ziplock bag. Add the steak and toss to coat. Refrigerate overnight, or for at least 8 hours.
Add all chimichurri ingredients to a food processor or high-speed blender and pulse until smooth and well combined. Transfer to a jar or container and refrigerate until ready to use.
Oil a grill pan or outdoor grill, and preheat to medium-high heat. Grill the flank steak for 8-9 minutes on each side.
Remove the steak and set it on a cutting board for at least 10 minutes to rest. Slice the steak against the grain, then top with chimichurri sauce and serve!
Notes
The chimichurri sauce is zesty and pairs perfectly with this marinated flank steak!
I was able to find a flank steak that was 3 lbs. Many supermarkets cut up flank steaks into smaller pieces. You can use 2 or 3 flank steaks that total up to 2 1⁄2 or 3 lbs for this recipe, that’s no problem!
