The Secret to Perfectly Seasoned Fajitas
The magic in this fajita recipe crockpot method comes down to the spice blend. Chili powder, cumin, and smoked paprika create that classic smoky, earthy fajita flavor, while a splash of fresh lime juice at the end brightens everything up. Garlic and a little chicken broth keep the chicken from drying out during the long cook time, and the natural juices from the peppers and onions mingle right in to create a light, flavorful sauce.
Chef's Tip: Resist the urge to add extra liquid. Chicken and vegetables release a surprising amount of moisture as they cook low and slow, so too much broth can leave you with watery fajitas instead of that rich, concentrated flavor you want.
Low Carb and Customizable
