Hey, Hi!! Let’s have a Fajita Thursday!!!

Steak Fajitas with Chimichurri and Cucumber Salsa | @hbharvest

Okay, so I may be a little overly excited about these here steak fajitas but I just can’t help it. Something about fajitas just screams Fiesta! They’re such a fun food to make and to eat! 🙂

Ever since traveling to San Diego last year, I’ve been slightly fajita OBSESSED. In San Diego, they sure do know how to do fajitas right. Meaning they’re served on a sizzling hot cast iron skillet where you can still see the heat coming off the peppers. It’s kind of amazing, and completely delicious! One thing I noticed were all the different salsas and sauces that were served with each and every fajita we ordered. Anyone who reads regularly knows how much I love my salsas and my sauces, so clearly I was in Mexican food La La Land. Today I am recreating my San Diego fajita experience with these steak fajitas, complete with a Mexi inspired chimichurri and a super fresh cucumber salsa.

The great thing about fajitas is that they are so simple and FAST. Just marinate the steak, sear it along with peppers, make your salsa and chimichurri, warm up your Old El Paso flour tortillas, stuff everything inside…add a little cheese…a little guacamole…and EAT.

Not gonna lie, these fajitas are kind everything… and with Cinco de Mayo right around the corner, I could not think of a better dish to get your Cinco on! So bring on fajita night, I am so ready!

Okok and speaking of Cinco de Mayo?!?!

Are you guys ready? It’s exactly two weeks from today and while I know it may be a tad early to be chatting about it, I am pumped. That will become very clear over the next fourteen days. I take my holidays pretty dang seriously around here. I am not really into any foodie holidays, but Christmas, Easter, Halloween, Thanksgiving, 4th Of July and Cinco de Mayo are all my favorites, I just have a lot of fun creating holiday inspired recipes.

Cinco de Mayo though, yeah, that’s an especially loved holiday, and for a few reasons…

ONE: um hello?!? It’s a holiday that’s all about Mexican food and culture and when could that ever be a bad thing? I think If I had to eat one type of food for the rest of my life it might be Mexican. It’s bright, fresh, spicy and just full of all my favorite foods and flavors…mangos, pineapples, jalapenos, corn, cilantro, lime, etc…I could go on an on. 🙂

TWO: unlike Halloween, Thanksgiving and Christmas, Cinco de Mayo recipes can be enjoyed year-round. They aren’t so specific that you’d only want them on Cinco de Mayo. Like I only make Christmas cookies during Christmas, but you know I’m making tacos, salsa, guacamole and fajitas year-round!

THREE: for the most part, Mexican recipes tend to be pretty fresh. Full of produce, lean meats…tequila…and cheese. Double YESSSS.

So you see? Clearly Cinco de Mayo rules. And because of this we’ll be talking a lot of Mexican over the next couple of weeks.

Bring it on.

Alright, so let me tell you about these here Steak Fajitas with Chimichurri and Cucumber Salsa. First, I actually made a recipe that all of my brothers would eat and love. Granted they wouldn’t touch the chimichurri or the salsa, but they would for sure be into the meat and the peppers.

The steak is simply seasoned, marinated and then cooked, sliced and stuffed into warm tortillas. The tortillas are then topped off with a Mexi inspired chimichurri sauce. Then topped again with a little cucumber salsa – complete with a little mango and lots of lime, and then finished up with a sprinkle of cheese!! Of course.

I mean, really could there be anything better?!?

Thinking no.

Sooo, fajita Thursday? Can we make that a thing??

  • 1/2 teaspoon cumin
  • Zest + juice of 2 limes
  • Salt + pepper
  • 1 1/2 pound flank steak cut into 2-3 three smaller pieces

Cucumber Salsa

  • 1 cucumber diced
  • 1 mango peeled + diced
  • Juice of 2 limes
  • 1/3 cup fresh cilantro chopped
  • 1-2 leave jalapenos seeded + chopped ( some seeds in for more heat if desired)
  • Pinch of salt to taste


  • In a large gallon size zip-top bag, combine the olive oil, chili powder, smoked paprika, cumin, lime juice and a good pinch of salt + pepper. Add the steak and rub the marinade into the steak, making sure the steak has been well seasoned. Place in the fridge for 1 hour or up to 12 hours (the longer you marinate the steak, the more flavor it will have).
  • Meanwhile, combine on the ingredients for the chimichurri in a bowl and toss to combine. Season with salt, taste and adjust as needed. Cover and keep in the fridge until ready to serve.
  • For the cucumber salsa, combine all the ingredients in a bowl and toss to combine. Taste and add salt as needed. Cover and keep in the fridge until ready to serve.
  • When ready to cook the steak, heat a large cast iron skillet or grill pan over medium-high heat. Add a tablespoon of olive oil and once hot, add the peppers and a pinch of salt and pepper. Stir-fry the peppers for 4-5 minutes. Remove the peppers from the pan. Return the pan to medium-high heat. Sear the steak for 3-4 minutes and then flip and continue cooking for another 4-5 minutes or until the steak reaches your desired doneness. Cooking times will vary depending on the size and thickness of your steak. Remove from the heat and allow to rest 5-10 minutes, then slice against the grain.
  • To serve, divide the steak and peppers among warm tortillas and drizzle with chimichurri sauce. Add a scoop of salsa and crumble on the cheese. EAT!


*Chicken can easily be used in place of the steak. *Pineapple will work just a great as mango in the salsa!

    Hoping to make this tomorrow. Is 1-2 “leave jalapeños” a typo? I’m assuming it should be 1-2 jalapeños. Please advise! Many thanks.

    1. Hi Maura,
      Yes, that is correct, 1-2 jalapeños. I hope you love the recipe, please let me know how it turns out!! xTieghan

  2. Hi! I accidentally sliced the steak into strips first instead of 2-3 large pieces. How would you adjust the cooking time/ technique?


    1. Hey Marilyn,
      You can still follow the recipe as is. Let me know if you give it a try, I hope you love the recipe! xTieghan

    Made these last night and they were delicious!! I didn’t have mango or pineapple for the cucumber salsa but I had a ripe pear and it was a great substitute! Thanks for continuing to provide these fantastic recipes!

    The chimichurri for this recipe was RIDICULOUS……in the best way! Wow, eating it by the spoonful. The steak marinade was perfect. My mango wasn’t quite ripe so the cucumber salsa wasn’t as good as I hoped but a good recipe and added a nice crunch. It’s the mangoes fault ?.

    Perfection!!! Everyone was humming at dinner. As always a home run with flavor and simplicity… used the left overs and made breakfast burritos.

  6. I made these for my mom and sisters and everyone loved them! I added some mesquite seasoning and cumin to the steak, I also put the bell peppers on the grill! So amazing!

  7. Wow triple yum! Had to google a couple of ingredients as different names in Australia but the end result was more please and can you cook it again!
    The only trouble with your recipes is I never have leftovers!
    Keep on cooking my goal is to try all your recipes!

  8. One word … YUM. Made these last night and I couldn’t believe how fresh and vibrant it all was , and how well it married together! The chimi is out of this world! We didn’t have any mango, so I added tomato and a little agave to the cucumber relish and it was amazing as a topping. I layered all of the leftovers onto some greens for lunch today and I’m already excited about it. I have saved / pinned so many of your recipes and look forward to this email every day! Thank you for all flavor that you pack into each recipe! Next up is the Salmon burgers this weekend! Love your work!

    1. AWESOME!! So happy you liked it!! Perfect substitutions!!
      Thank you for trying the recipes!! And commenting(:

  9. I was a little unsure on how all those strong flavours from each component would go together, but woweeee. Those were the most delicious fajitas! Going in the recipe vault.
