    First of all, anything Mexican I am a fan of and chicken fajitas is definitely one of them.  This is another meal I find helpful when mothering around :0  My new favorite word to use when you barely have enough time to eat, let alone cook a meal! That is why I am a big fan of slow-cooker meals. Set it and forget it!

    These chicken fajitas are made with clean simple ingredients. I like using different colored bell peppers as well because it makes the finished product look more appetizing.

    Ingredients for crockpot chicken fajitas

    Here is a list of ingredients you will need for this healthy dinner recipe.

    A photo of all the ingredients you will need to make this recipe with labels included.
    • chicken breast - fat cut off, I prefer the breasts because they cook more evenly than any other part of the chicken.
    • bell peppers - any color, stem, and seeds removed and sliced into julienne cuts.
    • one 14.5 oz can of diced tomatoes - no salt added, I prefer to be in charge of the amount of sodium that goes into my food.
    • white onion - sliced, I prefer white onions for this recipe because their flavoring is mild which doesn't overpower the rest of the ingredients.
    • minced garlic - minced, this is an ingredient I usually cut corners with buy Spice World's Minced Garlic and just leave it in my fridge.
    • chili powder - this spice has a savory, aromatic flavor that I use in most of my chili recipes.
    • cumin - has a warm earthy, and slightly nutty flavor and happens to be one of my favorites.
    • oregano - has a strong pungent flavor with a little earthy tone.
    • salsa - adds flavor and heat.
    • smoked paprika - has a smoky woodsy flavor with a hint of sweetness.
    • lime - the juice from half a lime. Love using a handheld juice squeezer for this.
    • pure honey - cuts the acidity of the tomatoes and adds a tint of sweetness.

    How to make chicken fajitas in the Crockpot

    Step-by-step directions on how to make healthy chicken fajitas in the slow cooker.

    Step 1 - Pour half of the can of diced tomatoes into the bottom of the crockpot. Top with sliced peppers and onions.

    Step 2 - Place chicken on top of vegetables and coat evenly with the oregano, cumin, chili powder, smoked paprika, and minced garlic.

    Steps one and two of the cooking process to make this recipe.

    Step 3 - Then top evenly with salsa and the remaining half of the can of diced tomatoes. Set the slow cooker on high for 2 - 3 hours or on low for 3 - 4 hours.

    Step 4 - Mix the honey and lime juice in a small mixing bowl and pour into the slow cooker. Using 2 forks shred the chicken.

    Steps 3 and 4 in the cooking process to make this recipe.

    Step 5 - Assemble your fajitas. I love my panini press so I use that to make my fajitas, but you don't need one. You can easily roll the chicken mixture inside a tortilla with some cheese or your choice of topping.

    Substitutions and Variations

    Here are some ingredient recommendations in case you don't have all the ingredients on hand.

    Chicken Breast - you can also use chicken thighs, but the cooking time might be longer because they have more fat.

    White Onion - if you don't have a white onion on hand you can also use yellow onions for fajitas or red onions, but be aware red onions have a much stronger taste.

    Diced Tomatoes - can omit this ingredient or replace it with more salsa.

    Smoked Paprika - can use regular paprika here.

    Lime - can swap out lime for lemon juice if you prefer.

    Cookware

    To make healthy slow-cooker chicken fajitas you will obviously need a crockpot. I also LOVE my panini press. I take the fajita mix and press it between the whole wheat tortilla with the cheese and it's a game changer. You don't need a panini press, but it enhances the dish for sure.

    How can the kids help

    I love love love including my kiddos in helping me make my meals. Here are some ways you can have your child help you make this dish.

    • Using a kid-friendly knife have them cut your peppers into julienne pieces. I took a cooking class in college so I am an expert in the types of cuts a vegetable can be cut into. A julienne cut slices food into thin, uniform strips.
    • They can help you measure all the ingredients and add them to the slow cooker.
    • Show them how to use a handheld juice squeezer to extract the lime juice. They can also squeeze one using their hands.

    Tips and FAQ's

    Can you use frozen chicken in the crockpot?


    Yes, you can! The cooking time will just be longer.

    How do you store the leftovers?


    Store your leftovers in an airtight container in the fridge for up to 5 days. They can easily be reheated in the microwave.

    What is the comparison of using plain Greek yogurt to sour cream as a topping?


    You can't have chicken fajitas without that sour cream taste to smear all over each piece.  When I first decided that I wanted to become a health nut I discovered that plain Greek yogurt tastes exactly like sour cream. 

    The comparisons of the two are as follows - 4 ounces of plain Greek yogurt has only 130 calories, 5 grams of carbs, 11 grams of fat, and 4 grams of protein.  As opposed to only 1 tbsp of sour cream which has 208 calories, 6 grams of carbs, 19 grams of fat, and only 2 grams of protein.

    • 1 container plain greek yogurt topping/optional
    • ⅓ cup salsa
