Slow Cooker Chicken Fajitas

We take Mexican night very seriously at our house, and these Slow Cooker Chicken Fajitas are my idea of perfection. The chicken is deliciously seasoned in a punchy marinade, topped with onion and peppers, and finished off with salsa for a simple meal you will make time and again.

My life is pretty crazy these days! 

That means now, more than ever, I am relying on super-easy recipes. If it is something I can throw together in 15 minutes or less that the whole family will enjoy, it is a winner in my book!

I have long loved my slow cooker, and these Slow Cooker Chicken Fajitas are one of my go-to recipes. I marinate the chicken overnight and then throw everything in the Crock-Pot a few hours before serving. It couldn't be easier.  

Ingredients for Making Crockpot Chicken Fajitas

• Chicken: I used chicken breast, but if you prefer thighs, that works as well.
• Lime Juice:  This adds a nice pop of acid to the marinade.
• Oil: Either olive oil or avocado oil will work here. Though I don't typically use olive oil for cooking, it is fine in the slow cooker.
• Garlic: Fresh minced garlic adds a big pop of flavor. Adjust the amounts to your liking.
• Seasonings: I used a blend of garlic powder, ground cumin, salt, and pepper. If you would like, you could use a packet of fajita seasoning instead.
• Peppers: Try using different colors for a pretty presentation.
• Onions: I typically use yellow or white onions, but red works too.
• Salsa: Fresh salsa from the produce section adds a pop of flavor.
• Fixings: You will want tortillas, shredded cheese, sour cream, and possibly more salsa.

Tips & Tricks

• If you would like to use a packet of taco seasoning in place of the seasonings in the recipe, feel free to do so.
• If you prefer your meat browned, you can drain it from the marinade and saute it in a skillet until browned before transferring it to your slow cooker.
• Mexican seasoned diced tomatoes may be used in place of the salsa.
• Short on time? You can often find pre-cut vegetables in the produce section of your grocery store.

Serving Suggestions

Between the fajitas, tortillas, and fixings, this makes a delicious meal on its own. If you would like to serve it with a side, try this Spanish Cauliflower Rice, Spanish Brown Rice, or Cilantro Lime Slaw.
