Grilled flank steak with salsa criolla is a delicious grilled meat dish that is so full of flavor and really easy to make. The criolla sauce is Argentinian and it is so amazing and really big on flavor.

About this steak with salsa criolla:
If you like to grill steaks with just salt and pepper, the criolla sauce added to the top when serving will take care of the rest! This Argentinian steak recipe with salsa criolla has a step by step guide for flavoring the meat along with making the criolla sauce that goes on the meat after cooking.
Origins of Argentinian Salsa Criolla:
This flank steak and salsa criolla recipe comes from my sister in law who is a wonderful chef and someone who has studied the history of food extensively, especially regarding the countries of South America. While this dish is used all over Argentina to this day, the exact origins is believed to have come about during the time of the Spanish colonization many years ago.
From studying the Peruvian culture (which was greatly intertwined with other South American countries at the time) what was learned was that many countries in South America called foods that were invented in the new world, but that were made with old world ingredients (and eaten mostly by Europeans) creole or "criolla," as opposed to indigenous."
I love learning about the different foods we eat and how they came about!
Two other sauces that come from the Argentinian region are chimmichuri and rojo chimichurri. Those are full of parsley and garlic and both are equally delicious!
Ingredients for the steak and salsa criolla:
Most of the items for the salsa criolla, you will probably have in your refrigerator or pantry making this a great recipe to have on hand. The items you will need for this flank steak recipe are:
Salsa Criolla
- red pepper
- tomatoes
- shallot or Spanish onion
- White vinegar
- dried or fresh thyme
- olive oil
- salt and pepper
Flank Steak
- flank steak (or skirt steak)
- garlic

- chili powder
Another thing that I really love about this dish is it is really fool proof! This will never come out bland and it will always be a hit! The criolla sauce can be used on many different items too.
I love using it on chicken or as a dip for french fries. You could even scoop it up with tortilla chips. I love any type of salsa to be honest!
Make it Ahead of time
Flank steak with salsa criolla can be made the night before and will actually taste even better that way. The salsa criolla will have time for the flavors to all marry together.
If you are using the rub recipe for the steak, that will also need a bit of time to absorb into the meat.
As I mentioned above, I often skip the rub and just make the salsa criolla and then season the meat with salt and pepper before grilling. No matter what your schedule allows for, it will come out great.
