I know you’re no stranger to this, but easy crockpot meals are just the way we do life here.

  • In the summer, when life is crazy and the oven heats up the house too much.
  • In the winter, when we love how the smell and coziness of a slow cooker dinner cooking away all day.
  • On a busy weeknight, when you have 5 minutes to throw something in the slow cooker before the kids burst in the door, or during the baby’s nap time, or for your family on your way out of the house for the night shift.

We have many favorite slow cooker meals here, and these fajitas are just the tip of the iceberg.

This Crock Pot Pulled Pork is loaded with flavor and the leftovers are also amazing! This Crockpot Mac and Cheese is also one of our favorites — just dump, stir and go! It’s ultra creamy and cheesy!

And this Slow Cooker Chicken Breast is so ridiculously flavorful and juicy thanks to one special ingredient 😉

  • They’re loaded with flavor — we’ll get to that homemade spice blend later.
  • They’re multi-purpose — got leftovers? Make a chicken taco salad the next day for lunch, or fry up some quesadillas, or use it to top a pizza. The options are endless!

How to make Slow Cooker Chicken Fajitas:

  1. Pour the chicken broth into your crockpot and add your chicken breasts. Season well with the homemade fajita seasoning
  2. Add your vegetables and sprinkle with remaining seasoning
  3. Top with your salsa — try to spread it in a thin even layer to keep everything moist.
  4. Cover and cook — the exact time will depend on your preferences and how how your slow cooker cooks. I’ve found 4 hours on low to be lots, and you could also cook for 2 hours on high. If you need to leave it longer, be sure that your slow cooker switches to keep warm once the cook time is over.

      It could, but I think the peppers would be very soft by the time the chicken is cooked. If that is an issue for you, I would recommend the slow cooker, skillet or oven
