Storage Tips
The Best Way to Store Leftovers
Store leftovers in an airtight container in the fridge for 3-4 days, with toppings and tortillas stored separately.
Use leftovers to make Chicken Fajita Bowls or Chicken Fajita Salad! Perfect for meal prep.
Recipe Tips
- Caldo de Tomate – This is tomato bouillon, which you can typically find in the Hispanic section of the grocery store. You can also substitute with chicken bouillon or omit it completely.
- Chicken Breasts vs. Thighs – I use chicken breasts in this recipe because they always come out so juicy and tender! You can also use chicken thighs if you prefer; they give the fajitas a great flavor.
- Don’t Overcook – Use an instant-read thermometer to check the chicken for doneness (165°F), and don’t overcook the chicken as it can come out dry.
- Serve with Toppings – Toppings are a must for a fabulous fajita dinner! Sour cream is a staple, as is pico de gallo and shredded cheese. Try the Cilantro Lime Sour Cream from my Chipotle Chicken Tacos recipe for something extra special.

I agree with allergies and one who doesn’t use packets it’s wonderful to have the seasoning ingredients. You have 2 limes listed but don’t see where it says to add is this for garnish or are we adding to the he slow cooker thanks!
Add the juice after shredding the chicken.
Thank you for making this from scratch! So many of the pinners used packs of season mix, and that’s fine, but when some of us who can’t for allergy reasons need measurements, it’s nice to have them!
