I take tender spice-rubbed chicken breasts and slow cook them in a flavorful marinade along with peppers and onions. While these fajitas may not sizzle like the ones you get in a restaurant, they certainly do satisfy!

Grab the tortillas, because it’s time to dig into some homemade chicken fajitas! Everyone knows the best part about ordering fajitas from a restaurant is hearing the sizzle approach your table. But what if I told you that you could still get that flavor without having to fire up the grill?
I know, a sizzle-less fajita night doesn’t sound overly exciting. But trust me when I say that these slow-cooked chicken fajitas are nothing short of mouthwatering. The chicken is rubbed with a spice mix including chili powder, garlic powder, and more. Then, I cook it with the peppers and onions in a super flavorful marinade. These chicken fajitas are one of my favorite meals for Cinco de Mayo or as a change of pace for Taco Tuesday.
