Easy Chicken Fajitas made in the slow cooker are great for busy days where you can come home to dinner ready to eat! This easy recipe has the same yummy taste as traditional fajitas, but half the work! Skip the marinading and sauteing, this recipe allows you to combine all ingredients to either freeze for later, or dump directly into the slow cooker to start cooking. The slow cooker can take it from there! Cooking in the slow cooker will make the chicken tender, and it will absorb a lot of flavors. We created our own fajitas seasoning blend in the recipe because the pre-mixed packets tend to contain a lot of sodium. This way, we cut the sodium way down while keeping traditional chicken fajitas spices.

Chicken Fajitas is a low carb, high protein main dish that is perfect if you are new to meal prepping or a beginner cook. It can also be a great recipe to use for gatherings because it is gluten-free, dairy-free, nut-free, and diabetes-friendly. So, it can accommodate a lot of conditions!

Using chicken breasts lowers the total fat and saturated fat in the meal because chicken breast is a lean protein. You can also use chicken tenderloins which are still lean. Chicken tenderloins tend to be priced a little cheaper than chicken breasts. Chicken thighs may be even cheaper than tenderloins, but they tend to be naturally higher in saturdated fats compared to chicken breast or tenderloinds.
