    ✔️ Why should you try it?

    • Only 10 minutes of prep time
    • Leave it cooking all day on a low setting
    • Perfect for busy school nights

    🥘 Ingredients

    • Chicken Breasts - 1kg of boneless, skinless chicken breasts cut into bite sized pieces.
    • Onion - 1 white onion, sliced thinly.
    • Garlic - 4 cloves, peeled and chopped.
    • Peppers - I used a mixture of red and yellow peppers, sliced thinly.
    • Tomato Puree - helps create the smoky fajita sauce.
    • Fajita Seasoning - I make a homemade fajita seasoning combining chilli, cumin, smoked paprika, oregano, cinnamon and ground coriander.
    • Thickening Granules - so much easier than thickening with cornflour. If you can't get hold of thickening granules then use a cornflour paste. However, as the cornflour needs to reach boiling point to start thickening, you will need to transfer the fajitas to a saucepan on the hob for the final part of cooking.
    • To serve - lime juice, tortilla wraps, grated cheddar, salsa.

    🔪 Instructions

    The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post

    One: Place the sliced onions, peppers and chopped garlic in a slow cooker basin.

    Two: Place the chicken breast pieces on top.

    Three: Sprinkle over the fajita spices and spoon in the tomato puree. Season with salt

    Four: Give everything a mix and cook on low for 6 hours. Thicken the sauce by sprinkling in 2-3 tablespoons of the thickening granules and stir into the sauce until it thickens to your desired consistency.

    💭 Top tips

    • If you prefer you can use a ready-mixed pack of fajita seasoning. For 1 kg of chicken you will need to use 2 of the standard supermarket sachets.
    • Up the nutritional content of the dish by adding 1 tin of drained black beans.
    • If you like things spicy, double the quantity of chilli (see recipe card for amounts).
    • For shredded chicken (rather than chicken pieces), place whole chicken breasts into the slow cooker basin and shred with forks at the end of cooking.

    🍴 Serving suggestions

    I usually serve the slow cooker chicken fajitas with warm tortilla wraps, grated cheddar, guacamole, salsa, soured cream, lime wedges, and a side of baked carrot fries or air fryer sweet potato fries.

    Any leftover chicken can be served on a bed of rice the following day.

    🥡 Storage

    The cooked fajita chicken mix can be stored in the fridge for up to 3 days. It can also be frozen for up to 3 months. Once cooled, place the leftovers in a freezer-safe container with a plastic microwave safe lid.

    ❓ FAQS

    Can you put raw chicken breast in the slow cooker?

    Yes! I very rarely brown meat before putting it in the slow cooker, although some people do prefer to seal chicken in a frying pan first to allow excess moisture to escape. If you're using thickening granules at the end of cooking, this isn't really an issue. If however you can't get hold of thickening granules, and don't want to use cornflour to thicken the sauce at the end of cooking, then you might benefit from sealing the chicken first.

    What toppings do you put on fajitas?

    Traditionally, soured cream, salsa, guacamole and grated cheese are used as fajita toppings. I sometimes add sliced red onion and chopped coriander too.

    • Measuring Spoons

    Ingredients

    Metric - US Customary
    • 1 kg Chicken Breasts cut into bite size pieces
    • 1 Onion sliced
    • 4 Garlic Cloves peeled and chopped
    • 3 Red and or Yellow Peppers sliced
    • 2 tablespoon Tomato Puree
    • 3 tablespoon Thickening Granules

    Fajita Seasoning

    • 1 teaspoon Chilli Flakes
    • 1 tablespoon Cumin

    • 2 teaspoon Oregano
    • ½ teaspoon Cinnamon
    • 2 teaspoon Ground Coriander

Bring to the boil on the hob and allow to thicken. I suggest using 2 tablespoon of cornflour with just enough water to make a paste.
