Ingredients for steak fajitas including flank steak, bell peppers, onion, spices, olive oil, and citrus marinade components on gray surface.

Steak: I’m using flank steak. It’s lean and excellent for marinating. Plus, flank steak cooks very quickly, so you’ll get your meal ready in a flash!
Marinade: This consists of olive oil, orange juice, lime juice, white wine vinegar, garlic cloves, and fresh ginger. The spices that we’ll be using are dried oregano, chili powder, ground cumin, smoked paprika, and ground cloves. We’ll also add both chipotle peppers in adobo sauce along with adobo pepper paste.
Vegetables: I’m using a variety of peppers, including poblano, red and yellow bell peppers. We’ve also got sliced white onions here.
Salt and pepper: Necessary seasoning to taste.

How to Make Steak Fajitas

Combine all marinade ingredients in a bowl or zip-top bag. Add the flank steak, ensuring it’s well coated. Marinate for at least 4 hours, preferably overnight.

While the steak cooks, heat a separate pan over medium heat with a bit of oil. Add the peppers and onions, cooking until softened and slightly charred. Optionally, add 2–3 teaspoons of the leftover marinade for extra flavor. Season with salt and pepper to taste.

Tips for Restaurant-Style Fajitas at Home

Use flank or skirt steak for the best texture and flavor. These cuts absorb marinade well and become super flavorful when cooked quickly over high heat.
Marinate for at least 4 hours, but overnight gives the best flavor and tenderness. Acidic ingredients like orange juice, lime juice or vinegar help tenderize the meat.
Preheat your pan/grill fully. A screaming-hot cast iron pan or grill gives the steak that caramelized, smoky char—just like restaurant-style fajitas.
Don’t overcook the steak. Aim for medium-rare to medium (130–135°F internal temp). Overcooking makes flank steak tough.
Let the steak rest before slicing. Resting for 10 minutes locks in juices. Skipping this can lead to dry steak.
Slice against the grain. Crucial for tenderness. Look at the muscle fibers and slice perpendicular to them.
Cook the peppers and onions separately. They’ll caramelize better and won’t get steamed from steak juices. Add a splash of the marinade for extra flavor.
Offer a toppings bar. Let people customize with lime wedges, salsa, guac, sour cream, pickled onions, shredded cheese, or cilantro.

How to Store Fajitas▼

Fajitas are definitely at their best when fresh, but if you are looking to use this recipe as a meal prep recipe or have leftovers, then all you need to do is transfer the contents into an airtight container and place in the refrigerator. These steak fajitas will stay fresh in the fridge for 3-4 days. You can easily reheat this in the microwave for a minute or two or until fully warm. Keep in mind that the veggies may get a little soft when reheating.

Toppings for Fajitas

How to Serve Steak Fajitas

Self-serve: This is a fun way to enjoy fajitas, and definitely my favourite way to get that restaurant experience! You’ll have a spread with tortillas, toppings, and the fajitas in the pan for you and your party to serve and assemble your own tortillas!
In a bowl: You can pair these steak fajitas with some rice. Some perfect options here would be Steamed Basmati Rice, Chipotle-Style Cilantro-Lime Rice, or Mexican Red Rice.
On its own: If you follow a low carb diet, then you can enjoy the steak and veggies on their own if you would like for a high protein meal!
