Slow Cooker Chicken Fajitas

There’s nothing like walking into the house after a long day and being greeted by the aroma of fajitas slow cooking away.

There's nothing like walking into the house after a long day and being greeted by the aroma of fajitas slow cooking away.

Whether it’s Mexican Monday or Taco Tuesday, slow cooker chicken fajitas are always a good idea. Granted, fajitas aren’t technically tacos. I get it… BUT they do make a great alternative. You can have Mexican-style slow cooker meals several nights of the week if you add Chicken Burrito Bowls and Chicken Carnitas to the lineup. Meals that are easy and packed with flavor every night of the week? Yes, please!

Making chicken fajitas in the slow cooker is a set-it-and-forget-it kinda meal. And who wouldn’t love that! I love leaving my slow cooker on low while I’m away from home. Before you know it, dinner’s ready and you didn’t waste time standing over a stove all day. We really love this slow cooker because it’s programmable, making it easier than ever to have dinner ready when you get home.

These chicken fajitas are so juicy and flavorful and your house will smell amazing. Loaded with bell peppers, onions, diced tomatoes and a hint of lime, just one whiff and your mouth will be watering for dinner. They’re a hit with the whole family. I bet you have most of the ingredients in your house as we speak. Here’s how easy it is to bring these bad boys to life.
