Easy Step-by-Step Guide
- Douse the Steak with Chimichurri:
- Spoon loads of the green sauce over the sliced meat laid out on a plate. Try to spread it so every slice is covered in tangy herby goodness.
- Let the Steak Rest:
- Once you’re done grilling, set the steak aside for five minutes. This lets the juices settle back in and keeps it moist when you slice.
- Get Grilling:
- Slap your steak onto those hot grates. Leave it alone for about four or five minutes to get a nice crust, then flip for another four to five minutes for medium rare. Pressing down isn’t needed—this keeps every drop of juice inside.
- Heat Your Grill Up:
- Start your grill or grill pan on medium high. Aim for around four hundred degrees if you have a thermometer. Give the grates a quick brush with some oil so nothing sticks.
- Dress Up the Steak:
- Put the steak on a cutting board and sprinkle both sides with lots of salt and black pepper. Let it hang out at room temp for about thirty minutes. This helps the flavors get all the way in and keeps the steak even as it cooks.
- Whip Up That Chimichurri:
- Chuck parsley, garlic, vinegar, oregano, salt, pepper, and crushed red pepper into a food processor. Blitz until everything’s chopped small but not mushy. Pour the olive oil in slowly while it’s running so the sauce stays a bit chunky and light. Scrape the sides and give it another quick mix to blend everything together.

I love the way those bits of parsley and garlic stick to every juicy piece of steak. When we made this for a backyard party, our buddies were already demanding the details before we even sat down to eat.
Storing Leftovers
If you have steak left, stash it in a sealed container in the fridge—it’ll be good for two to three days. Toss leftover chimichurri in a jar with a lid and keep it chilled for tomorrow’s sandwiches or as a marinade. Want to freeze the steak? Wrap tightly and let it thaw in the fridge before warming it up.
Switch-Ups for Ingredients
Mix curly and flat parsley for some cool texture. Hate parsley? Swap in cilantro or go half and half for a twist. No red wine vinegar? White wine vinegar or even lemon juice will do—just taste as you go to get it right.

Serving Ideas
Pair your steak with grilled veggies, roasted potatoes, or grab some crusty bread to scoop up all that green sauce. Or keep it chill by tucking slices into tortillas with avocado and lettuce for a tasty taco.
Where It Comes From
This classic Argentinian sauce has always been the star at barbecue feasts called asados. Every group puts their own twist—sometimes more garlic, other times extra oregano. It’s all about bringing everyone together and having a good time.
