The moment this steak hits a hot skillet, grill, or Blackstone, you’ll understand why people couldn’t stop talking about it. The sizzle, the aroma of garlic and citrus, and those beautifully charred edges create the kind of anticipation that has everyone asking, “When is the steak ready?” Long before dinner was served, guests were already gathering around to see what smelled so incredible. Tender, juicy, and packed with bold Tex-Mex flavor, this fajita steak delivers everything you want in a restaurant-quality meal right from your own kitchen.
I made this recipe for a build-your-own Tex-Mex bar where guests could create tacos, burritos, burrito bowls, nachos, and fajita plates exactly the way they liked them. It quickly became one of the most talked-about dishes of the night, and the compliments didn’t stop when the party ended. The next day, I received text messages from guests asking about the steak and telling me how much they loved it. Thanks to a vibrant marinade loaded with fresh citrus, garlic, herbs, and achiote, every bite is savory, juicy, and unforgettable—the kind of recipe people remember long after the last bite is gone.

- 3 lb top sirloin steak (1360g) (or skirt steak or flank steak)
Marinade
- 6 tbsp orange juice (90g)
- 2 tbsp plus 2 tsp fresh lime juice (50g)
- 1/4 cup avocado oil or vegetable oil (55g)
- Garlic & Aromatics
- 5 cloves garlic (15g)
- 1/2 medium white onion 75g, roughly chopped
- 2 tbsp plus 2 tsp fresh cilantro (10g)
- 1 tbsp kosher salt (15g)
- 1 1/2 tsp black pepper (3g)
- 1 1/2 tsp ground cumin (3g)
- 1 tsp smoked paprika (2g)

- 1 tsp garlic powder (2g)
- 1 tsp Mexican oregano (1g)
- 0.75 oz achiote paste (21g)
Instructions
- Slice Against the Grain: Trim only large hard pieces of fat from the steak. Slice into thin fajita strips against the grain to ensure every bite stays tender and juicy.
- Blend the Marinade: Add orange juice, lime juice, oil, garlic, onion, cilantro, kosher salt, black pepper, cumin, smoked paprika, onion powder, garlic powder, Mexican oregano, and achiote paste to a blender. Blend until completely smooth.
- Check the Flavor: Taste the marinade before adding it to the steak. It should taste bold, savory, garlicky, and slightly salty since toppings and sides will mellow the final flavor.
- Marinate the Steak: Place the sliced steak into a large bowl or zip-top bag. Pour the marinade over the meat and massage thoroughly to coat every piece. Cover and refrigerate for 8-20 hours.
- Prepare for Cooking: Remove the steak from the refrigerator 30 minutes before cooking to encourage better browning and more even cooking.
- Heat the Cooking Surface: Preheat a grill, Blackstone, cast iron skillet, or stainless-steel skillet over high heat until very hot.
- Cook in Batches: Add steak in a single layer and cook in batches if necessary. Avoid overcrowding the pan to ensure proper searing and caramelization.
- Sear to Perfection: Cook for 2 to 4 minutes total, stirring occasionally, until browned with charred edges while remaining juicy inside.
- Avoid Overcooking: Remove the steak once it is browned and cooked through but still tender. Slight pinkness is acceptable depending on preference.
- Rest the Steak: Let the steak rest for 5 to 7 minutes before serving to help retain its juices.
- Finish the Steak: Lightly toss the steak with the butter mixture to add shine, moisture, and an extra layer of savory flavor.
- Serve and Enjoy: Serve immediately in tacos, burritos, burrito bowls, nachos, fajita plates, salads, or alongside rice and beans.
