Every recipe has a surprisingly tasty twist, which is so fun and so delicious. Kelly has come up with some fantastic recipes. We have loved cooking our way through the book and I know you will too! So what is the secret ingredient in this recipe? Let’s find out!

Chimichurri Sauce

The secret ingredient is used in the chimichurri sauce and it really makes the sauce come to life. Any guesses? Shishito Peppers! YES!! Shishito peppers have a fresh, peppery, citrus flavor similar to a green pepper but they are a little sweeter. They aren’t normally hot, except for that 1 in 10 chance, so the peppers don’t make the sauce super spicy. They add SO much GOOD flavor! Blister the shishito peppers in a hot pan before adding them to the sauce to bring out the best flavor. Once the peppers cool off, remove the stems. The rest of the ingredients are classic!

Herbs– Italian parsley, cilantro, and oregano. Make sure you use FRESH herbs! Shallot– look for shallot by the garlic and onions in the grocery store. Garlic– peel first! Red wine vinegar– it adds a robust and vibrant flavor with a little bit of tang. Lime juice– use fresh lime juice, not bottled lime juice. You want the freshest taste. Honey– the honey adds the perfect amount of sweetness to balance out the vinegar and lime juice. Olive oil– a must for bringing the sauce together.

You make the chimichurri sauce in a food processor or blender and it comes together in just a few minutes. The sauce really makes the steak, so don’t skip it! You can also use the sauce on chicken, fish, vegetables, bread, and more! The sauce will keep in the fridge for a few days, so you can make it in advance if you want.

How to Make Grilled Flank Steak

Once you have the chimichurri sauce made, it is grilling time. You can grill outside on a grill or inside using a grill pan.

Preheat a grill or heat a stovetop grill pan over medium-high heat. If using a grill, lightly oil the grate.Season the steak generously with salt and pepper. Place the steak on the grill and cook undisturbed for 6 minutes. Flip it once and continue cooking until it reaches your desired level of doneness. For medium-rare, cook the steak until it reaches an internal temperature of 130 degrees F.Transfer the steak to a cutting board, cover loosely with foil, and let rest for 10 minutes.With a sharp knife, slice the steak against the grain into thin strips. Top the steak with the delicious chimichurri and serve immediately.
