Chimichurri is quickly becoming one of my favorite ways to add flavor to a dish, whether it’s Grilled Chimichurri Chicken or Zesty Chimichurri Burgers. But for today, let’s focus on this grilled flank steak with avocado chimichurri! It’s super simple to make, gluten free, and fits into the paleo diet—and best of all, it packs a HUGE punch of flavor.
Why This Is My Favorite Way to Do Flank Steak
Flank steak has always been a favorite in our household, but this method takes it to a whole new level. Here’s why we love it:
- Tender and juicy. The thing about flank steak is that it can be tough if not cooked properly. Grilling is perfect for it because when you cook the steak quickly over high heat, you get tender and juicy results. (Looking for more delicious ways to cook flank steak? Try this Best Marinated Grilled Flank Steak Recipe or this Asian Grilled Flank Steak recipe.)
- Big flavor. The grilled flank steak is nice and simple, with just salt and pepper to season. The flavor comes from the chimichurri! It’s packed with fresh herbs, lime juice, tangy vinegar, and some heat from the red pepper flakes. Then I mixed this chimichurri base with creamy avocado and whoazer! It totally puts this dish over the top.
- A 20-minute dinner. And did I mention it’s done in less than 20 minutes? You’ll have a delicious, impressive dinner on the table in practically no time at all!
What You’ll Need
Here’s a list of the ingredients you’ll need to make this flavorful grilled flank steak recipe. Scroll down to the recipe card to find the ingredient quantities and recipe instructions.
Flank Steak:
- Flank steak – This lean cut of beef is ideal for grilling!
- Olive oil – Or another oil you like to use for grilling, like avocado oil.
- Salt and black pepper – All you need to season your grilled steak!
Avocado Chimichurri:
- Avocados – The creamy base for the chimichurri.
- Cilantro – This makes the sauce fabulously herbaceous. If you think cilantro tastes like soap, swap in parsley.
- Red wine vinegar – For a tangy kick.
- Lime juice – This adds a nice, zippy flavor. You can make your chimichurri extra citrusy by adding some zest from the lime too.
- Red pepper flakes – Adds a hint of heat, but you can skip it or add less for a milder sauce.
- Garlic – Because garlic and steak are a match made in heaven!
- Salt – To balance the flavor.
How to Make Grilled Flank Steak With Avocado Chimichurri
Here’s how easy it is to make this grilled flank steak recipe!
- Prepare. Preheat your grill to high and allow the steak to come to room temperature. Season both sides with salt and pepper.
- Grill the steak. Set the steak on the grill and cook for 4 to 6 minutes per side, or until the internal temperature reaches 130ºF. Let the steaks rest for 5 minutes.
- Make the chimichurri. Toss all of the ingredients in a bowl.
- Serve. Slice the steak against the grain and serve it with the avocado chimichurri.
Tips and Variations
These tips will help you make sure your grilled flank steak and avocado chimichurri turn out perfect!
- Monitor the internal temperature. Yeah, it’s a bit of a hassle, but it is SO WORTH IT. You will never over-cook your steak again and it will always be tender and juicy.
- Marinate the steak. If you’ve got the time, marinate the steak in a mixture of olive oil, lime juice, garlic, and cumin for 30 minutes before grilling.
- Top with crumbled queso fresco. Sprinkle it over the steak after adding the chimichurri. It has an awesome salty flavor and adds a little more richness!
Serving Suggestions
For a complete meal, serve the steak with warm tortillas taco-style or over a bed of rice or cauliflower rice. It would also be fantastic with a side of Air Fryer Asparagus or Crispy Garlic Herb Roasted Potatoes.
How to Store and Reheat Leftovers
- Refrigerator: Any leftover grilled flank steak can be stored in an airtight container and kept in the refrigerator for up to 3 days. The chimichurri will last about a day in the fridge, but it will start to oxidize and turn brown.
- To reheat: Warm leftover steak in the microwave or heat in a skillet over medium heat until warmed through.

I came for the recipe but stayed because of what you shared in this post. Thank you. 💝
Awe.. 🙂 thank you!
I just tried this recipe and it was delicious. My dad loved it too! And I love Chris Tomlin songs. Friends at church tease me sometime for having a lot of his songs on my playlist. Haha
Love him!! So glad your Dad loved the recipe!
This was fantastic! We’ve started planning on what else to use the Chimichurri recipe with other than flank steak. So good.
I am so glad you enjoyed it! You won’t be disappointed if you give the Zesty Chimichurri Burger a try! So good!
What is the nutrition facts for each serving? Im keto and track all my meals
I just updated the post to reflect nutritional information.
Hello! Do you know if the chimichurri sauce will keep for several days (in case I wanted to make batch meals from this recipe)?
Thanks!
Yes, I’ve kept it up to a week before and it’s been fine
This looks so good! Can I make this if I don’t have access to a grill though?
Sure, just sear it on a cast iron skillet Anna!
This recipe looks wonderful and I love what you said about the song inspiring you–that God loves us always and we are perfect exactly as we are, not by how well we “perform!”
ohh thank you so much Lisa! That means the world! I hope you get a chance to try this recipe. 🙂
Yum!! I’m going to try this 🙂
You’re going to love it!
This is delicious!! I frequent a Mexican restaurant where they serve a chimichurri sauce exactly like this! I even tried to duplicate it at home but wasn’t quite as good. This recipe is perfect! Thank you so much for sharing this!
Ohhh yeah! So glad Heidi! I’m obsessed with Chimichurri sauce, I’d put it on everything if I could. Glad you finally have a recipe to make at home! 🙂
Hey this is cool. I’ve never heard of Chimichurri before. (Love it when you find something new!) I’ll definitely add this to my list of steak condiments. Do you think it will go well with pork also?
Oh man Will! You are missing out! It is a game changer for sure! And honestly, it goes well with any protein so you’re good if you’re pairing it with pork!
I made the avocado chimichurri sauce tonight and it was so delicious! I also served it with flank steak but made it a bit differently (the store had a pre-marinated version). Husband loved the avocado chimichurri sauce too and he’s super picky! yay!
Awesome! So glad it hear it Jennifer! This recipe is one of our favorites. And way to go on the pre-marinated option, I bet it added so much flavor! You just need to be sure to look at the ingredients, a lot of times on the pre-marinated they add way more salt to help it “keep”. 🙂
I’m sensitive to olive oil, what oil can I use instead and not change the flavor?
You could use grape seed oil or canola oil
I’m going to try this tomorrow sounds delicious..I hope it’s good with new York strip, because that’s what I’m fixing.. I love your blog God always knows what we need and when we need it. Keep up the good work God has your back😀
Oh yeah, it will be good with new york strip, really any steak! 🙂
Thanks so much for the encouragement Karen, so appreciate it! Hugs!
This recipe was ridiculously delicious!! There was not one morsel left after my family got through with it. And the chimichurri with avocado was so tangy and yum that I’ve been making it repeatedly to try with different meats and salads. Glad I found this one, it’s a keeper! Thank you!
Oh hurray! So pumped to hear it Stacy! And gurl, you are so right! I would bathe in that avocado chimichurri sauce if I could. heaven in a bit! 😉

Words of wisdom, Krista! For a while a had a piece of paper taped to the wall above my desk that said “my blog stats do not define me”. It’s good to remember where my worth comes from.
Yes! Such a good idea love the note thing! Great reminder!
It’s hard not to focus on the numbers! I just read a quote yesterday that said “Don’t compare your inside with someone else’s outside.” I think it can apply to blogs as well. Your grilled flank steak sounds fantastic!
Soooo true! Love that quote! And thank you on the grilled steak front. 🙂
I could have written this post myself – this is EXACTLY how I have been feeling lately – totally discouraged and letting my numbers dictate my worth – NOT anymore!! thank you for this and the delicious recipe 🙂
Your welcome sweet friend! Keep your head up and your eyes straight… we are doing what we love and thats all that matters! 🙂
