Ingredients

  

• 2 –3 tablespoons avocado oil or olive oil
• 1 lb top sirloin steak cut into thin strips
• 1 lb boneless skinless chicken breast cut into thin strips
• 1 packet fajita seasoning or 3 tablespoons taco seasoning
• 1 red bell pepper sliced
• 1 green bell pepper sliced
• 1 large yellow onion sliced
• Flour tortillas or whole wheat tortillas
• Optional toppings: shredded cheddar or Mexican blend cheese sour cream, salsa or pico de gallo, guacamole, shredded lettuce, hot sauce

Method

 

1. Wrap your tortillas in aluminum foil and place in the oven at 250°F to warm while you cook the fajitas.
2. Heat a large skillet or sauté pan over medium-high heat. Add 1–2 tablespoons of oil.
3. Add the steak strips to the pan. Season with fajita or taco seasoning. Cook for 1–2 minutes to your desired doneness, then remove from the pan and set aside.
4. Add another drizzle of oil to the pan if needed. Add the chicken strips and season with fajita or taco seasoning.
5. When the chicken is about halfway cooked, add the sliced bell peppers and onion to the pan. Stir and cook together until the chicken is cooked through and the peppers and onions are tender and slightly caramelized, about 5–7 minutes.
6. Add the steak back into the pan and stir everything together for about 1 minute to warm the steak through.
7. Serve immediately with warm tortillas and your choice of toppings.

Notes

You can use steak only, chicken only, or add shrimp as a third protein — the seasoning and method work for all three. If adding shrimp, cook it first (1–2 minutes per side), set aside with the steak, and add back at the end.

Don’t skip warming the tortillas. Wrapping them in foil in a 250°F oven for the duration of cooking makes a noticeable difference — warm, soft tortillas hold everything together so much better.

For a bigger crowd, double the recipe and cook in two batches. Crowding the pan causes the meat to steam rather than sear, which changes the texture.

Top sirloin is Stephanie’s preferred cut for the steak — tender, affordable, and it slices easily into thin strips. Flank steak or skirt steak also work well.

Why These Chicken and Steak Fajitas Work

The thing that makes this recipe different from a lot of fajita recipes is that we cook the steak and chicken separately — and in that order. The steak goes in first to get a good sear, comes out, and then the chicken goes in with the peppers and onions so they all soften and caramelize together. When you add the steak back at the end, everything is cooked perfectly and nothing is overcooked or dried out. I have made this for just our family of seven and I have made it for a crowd of twenty — it scales beautifully either way.

The other trick I swear by is warming the tortillas in the oven. Wrap them in aluminum foil, slide them in at about 250°F while everything is cooking, and by the time the fajitas are done, your tortillas are warm and soft and ready to go. It is such a simple step and it makes such a difference in the final result. Nobody wants a cold, stiff tortilla under a pile of hot sizzling fajita filling.

One thing I love about chicken and steak fajitas is that they are completely customizable. I use top sirloin for the steak because it is tender, affordable, and holds up well to high heat. For the chicken, boneless skinless chicken breast cut into thin strips is perfect. You can absolutely do just steak, just chicken, or — like we often do — add shrimp for a third protein option. The seasoning works equally well on all three. A packet of fajita seasoning or about 3 tablespoons of taco seasoning is all you need for two pounds of meat total.

Chicken and Steak Fajitas FAQ — The Questions I Get Every Time

Do I really need to cook the steak and chicken separately for chicken and steak fajitas?

Yes — and it makes a real difference. Steak needs high heat and a fast sear to get that caramelized crust without overcooking. If you add the chicken at the same time, the pan cools down and you lose the sear. Cook the steak first over medium-high heat for a minute or two to your desired doneness, set it aside, and then cook the chicken with the peppers and onions. Add the steak back at the very end just to warm through. Everything finishes at the right texture.

What cut of steak is best for chicken and steak fajitas?

Top sirloin is my go-to — it is tender, affordable, and easy to slice into thin strips. Flank steak and skirt steak are also classic fajita choices if you can find them. The key with any cut is to slice it thin, across the grain, so every bite is tender rather than chewy. Amazon Fresh Flank Steak (Shop on Amazon) is a great option if you want to order ahead.

Can I make chicken and steak fajitas ahead of time?

You can slice all the meat and vegetables ahead of time and store them in the fridge for up to 24 hours before cooking. I do not recommend cooking the full recipe ahead and reheating — fajitas are at their best fresh off the pan, and reheated chicken can dry out quickly. If you need to get ahead, the prep work is where to focus. Then cooking only takes about 15 minutes when you are ready.

What toppings do you recommend for chicken and steak fajitas?

Our standard spread is shredded cheddar or Mexican blend cheese, sour cream, salsa or pico de gallo, shredded lettuce, and guacamole. Hot sauce is always on the table for whoever wants it. The beauty of fajitas is that everyone builds their own, so you can put out as many or as few toppings as you like. For a crowd, I like to set everything out in small bowls so people can go down the line and load up their tortilla.

Can I add shrimp to this chicken and steak fajitas recipe?

Absolutely — shrimp works beautifully with this recipe. Cook the shrimp exactly the same way as the steak: in the pan first with oil and seasoning, just 1–2 minutes per side until pink and curled, then set aside while you cook the chicken and vegetables. Add everything back together at the end. Shrimp cooks fast, so keep a close eye on it. If you are making all three proteins for a big crowd, cook in this order: steak, shrimp, then chicken with peppers and onions.

What kind of pan should I use for chicken and steak fajitas?

You want a large, wide pan that can hold everything without crowding. A 12-inch skillet or sauté pan is ideal. I use my SENSARTE Nonstick Ceramic Saute Pan (Shop on Amazon) — it is PFOA-free, induction compatible, and distributes heat beautifully. A cast iron skillet also works wonderfully if you want that classic sizzle. Whatever you use, make sure it is fully preheated before the meat goes in — that is how you get the sear.

How many people does this chicken and steak fajitas recipe serve?

Using 1 lb steak and 1 lb chicken (2 lbs total), this recipe serves 6–8 people. My family of seven eats this comfortably with a full toppings spread. If you are feeding a larger crowd — say 12–15 people — simply double the recipe and cook in two batches rather than crowding everything into one pan. A crowded pan steams the meat instead of searing it, and you lose the whole texture of a great fajita.
