Freezer Friendly Chicken Fajita Recipe

Fajita Ingredients in slow cooker

Ingredients for this recipe:

  • Chicken breast
  • Red and green bell pepper
  • Yellow onion
  • Garlic
  • Taco or fajita seasoning
  • Lime juice
  • Salsa

We really like to use green salsa in this recipe. Specifically, Trader Joe’s Hatch Chile Salsa, but any salsa will work great! 

Also, we have made this with both taco and fajita seasoning. I like fajita a little butter, but my husband prefers taco. Use whatever your family likes!

How to freeze fajitas:

This recipe makes an excellent freezer meal. We like to put all of the ingredients into a giant freezer bag BUT you can also separate it into smaller containers. 

  1. Combine the chicken, oil, lime juice, and seasoning in a gallon size freezer bag. Gently toss to combine. 
  2. Add sliced onion and peppers. 
  3. Seal, removing as much air as possible, label and freeze. 

When you are ready to cook, remove from the freezer and place in the slow cooker. Cook on low for 4 to 6 hours. 

Tips for this recipe:

  • Add the peppers and onions the last hour of cooking for a more crisp finish. Adding at the beginning gives you a softer pepper and onion.
  • No fajita seasoning? No problem! Substitute with 1 teaspoon chili powder, 1/2 teaspoon paprika, 1/4 teaspoon each onion and garlic powder.
  • I like to use Trader Joe’s Hatch Chile Salsa, but you can really use any salsa type!
