Ingredients for Chimichurri marinated flank steak

The recipe below is enough for 4 oz of steak. I like to make this in the summer when parsley and cilantro are growing in my garden. I mix up the chimichurri sauce in the blender and then put the steak and the sauce in a ziplock bag to marinate in the fridge for a day. Since I often make enough for 1lb of meat or more, I scale the ingredients to match*.

If we’re not eating it right away, this is great for meal prep because it can go right into the freezer so it is ready for when I want a taste of South America's answer to pesto sauce.

*There has been some discussion about scaling the salt in doubled/multiplied recipes. A decent rule of thumb is to start with 1.5x the salt for a doubled recipe, and half of the multiplied amount for larger scales and then adjust (so 4x the recipe would have 2x the salt of the single batch). Go light so you can taste and see where you are. You can always add more, but you can't take it out.

Chimichurri marinade for flank steak

Chimichurri sauce is an herb, oil, and garlic base. Some call it a South American sauce. Others get more specific and say an ​​Argentine sauce. Chimichurri on steak is exceptional, but chimichurri ingredients go well on just about everything. As I mentioned before, chimichurri feels and tastes like South America’s answer to pesto.

Flank steak vs skirt steak

Flank steak is often considered a tough cut of meat because it contains less fat than other cuts. But this doesn’t mean it’s tasteless. On the contrary, flank steak is flavorful and tender when cooked properly.

Flank steak is often used for making fajitas, tacos, burgers, and other dishes that require marinating. It’s also great in stir-fries, stews, and soups.

Flank steak is sometimes called London broil or skirt steak, but they are actually different cuts of meat. Flank steak is cut from the abdominal muscles of the animal. Skirt steak can be substituted for flank steak. However, it can also be a tougher piece of meat and become chewy if not cooked correctly. Both cuts do best with marinades and quick cooking on high heat. So which will be your choice? Flank steak vs skirt steak?

What makes flank steak so special? Here's why you should start eating more of this delicious cut.

Flank steak has a lot going for it!

  1. It's inexpensive. This means you can buy a whole flank steak for much less money than many other steaks.
  2. Easy to prepare. Season it with salt and pepper, then sear it on the stovetop or grill until browned, about 3-5 minutes per side.
  3. Full of flavor. Flank steak is known for its rich taste.
  4. A rich source of protein. Protein is essential for muscle growth and recovery. A 4 oz. serving contains over 20 grams of protein.
  5. It’s lower in fat than many more expensive and just as tasty steak options.
  6. Flank steak is a good source of iron.
  7. Also a good source of zinc.
  8. Naturally gluten-free.
  9. Low in saturated fat compared to other steak types.
  10. It has over 45% of your daily vitamin B3 in one serving.
  11. Chimichurri on steak is one of the best grilled beef combinations.

So which steak should you buy? The answer depends on what you’re looking for

Flank steak is usually sold as skirt steak, which is actually a different cut. Flank steak comes from the flat muscle at the bottom of the cow, while skirt steak comes from the top part of the cow. Both are delicious, but flank steak is leaner and more tender.

When my youngest son graduated from high school, I served flank steak fajitas. It was the first time I had marinated flank steak. WOW! Was it phenomenal! We had so many compliments and people taking seconds and even thirds. I am more of a chicken fajita person, and I was eating the flank steak over the chicken option. At that time, I realized that flank steak was going to be a part of our marinating and grilling meal planning

As a green sauce fan, chimichurri marinated flank steak is a welcome addition to our family's favorites.

What is the best method to cook flank steak?

This steak is best when cooked on high heat for a short time. I prefer to grill or pan sear flank steak. If it has been marinated, the grill is my first choice.

I am curious how flank steak tastes broiled, which is an option. Or in the air fryer. Please comment below if you have tried any of these methods or one I didn't mention.

Remember the last time you had a conversation with another person and thought, “Wow, what we were talking about really moved me.”

Many times, it is not the topic that makes the conversation meaningful, it’s the feelings that surround it. Like knowing you are being heard and that what you have to say is important to the other person. Offering that same safe, open and comfortable environment for others who are speaking leads to moving and memorable communication.
