SIMPLE INGREDIENTS YOU NEED FOR THE EASY CHICKEN FAJITAS

You will need the full ingredient list below to make the crock pot chicken fajitas (the exact measurements, nutrient information and full recipe are in the printable recipe card at the bottom of this post):

• Boneless, skinless chicken breasts 
• Fresh bell peppers – green bell pepper, red bell pepper, orange, or yellow.
• Large red onion – can also use a yellow onion if desired
• Can diced tomatoes with green chilies
• Garlic cloves
• Packet fajita seasoning mix – store-bought or my Homemade Taco Seasoning Recipe.
• Olive oil
• Fresh lime
• Sea salt and black pepper to taste
• Flour tortillas or corn tortillas 
• Your favorite toppings – such as sour cream, salsa, black beans, more green chiles, freshly squeezed lime juice, avocados or guacamole, fresh cilantro, etc.

HOW TO MAKE THE DELICIOUS CHICKEN FAJITAS

1. Start by adding a little olive oil to the bottom of your slow cooker to prevent sticking. Layer in the sliced bell peppers and onions, creating a colorful bed of veggie goodness.
2. Place the chicken breasts on top of the veggies. This way, they’ll absorb all those delicious flavors as they cook. Season with salt, pepper, and your fajita seasoning mix.
3. Pour the diced tomatoes with green chilies over the chicken and sprinkle with the minced garlic. Squeeze the juice of one lime over the top for a little zing. Drizzle with the remaining olive oil for that extra juiciness.
4. Cover and cook on low for 6-8 hours or high for 3-4 hours.
5. Once the chicken is tender and cooked through, remove it from the slow cooker and shred it using two forks. Return the shredded chicken to the slow cooker and mix everything together so the chicken soaks up all those incredible juices.
6. Warm tortillas and get ready to build your fajitas. Load up each tortilla with a generous scoop of chicken and veggies, then top with your favorite fixings—guacamole, salsa, shredded cheese, sour cream, fresh cilantro, you name it!
7. Wrap it up, take a big bite, and let the fiesta begin! These slow cooker chicken fajitas are juicy, flavorful, and seriously addictive. You might want to make extra because everyone’s going to want seconds.

TIPS AND TRICKS FOR BEST RESULTS

• Use Fresh Ingredients: Fresh bell peppers, onions, and garlic bring out the best flavor in your fajitas. Choose vibrant, firm veggies for the tastiest results.
• Layer for Even Cooking: Place the sliced peppers and onions at the bottom of the slow cooker, and the chicken breasts on top. This helps the chicken cook evenly and keeps the veggies from getting too soggy.
• Don’t Overcrowd the Slow Cooker: Make sure there’s enough room for the ingredients to cook evenly. If you’re doubling the recipe, consider using a larger slow cooker or two smaller ones.
• Homemade Fajita Seasoning: For maximum flavor, make your own fajita seasoning with chili powder, cumin, paprika, garlic powder, onion powder, and a pinch of cayenne. You can adjust the spice levels to your liking!
• Go Low and Slow: For the juiciest chicken, cook on the low setting for 6-8 hours. If you’re in a hurry, the high setting for 3-4 hours works too, but low and slow is the way to go for the best texture.
• Shred the Chicken: For easier eating, shred the chicken with two forks before serving. This helps soak up all the delicious juices and makes it perfect for wrapping in tortillas.
• Add Lime Juice Last: Squeeze fresh lime juice over the fajitas just before serving. This brightens up the flavors and adds a zesty kick that ties everything together.
• Warm Tortillas: Heat your tortillas before serving for the best texture. Wrap them in foil and pop them in the oven, or warm them individually over a stovetop flame for a slight char.

FAQS

CAN I USE CHICKEN THIGHS INSTEAD OF CHICKEN BREASTS FOR THIS SLOW COOKER RECIPE?

Absolutely! Skinless chicken thighs are a great option for a juicier result. They’re also less likely to dry out during the long cooking time, making them a perfect choice for this easy chicken recipe.

WHAT’S THE BEST COOKING TIME FOR THIS SLOW COOKER CHICKEN FAJITA RECIPE?

Cook on low for 4-6 hours or on high for 2-3 hours. The chicken should reach an internal temperature of 165°F. The longer cooking time on low heat helps the flavors develop and the chicken to become tender.

Yes! This is a perfect meal prep recipe. Cook a big batch and use it throughout the week for fajita bowls, wraps, salads, or even on top of cauliflower rice for a low-carb option. It’s a versatile complete meal that’s quick and easy.

ARE THERE ANY ALTERNATIVES TO USING A SLOW COOKER FOR THIS RECIPE?

If you don’t have a slow cooker, you can make sheet pan chicken fajitas by spreading the ingredients on a baking sheet and roasting at medium heat (around 400°F) for 20-25 minutes, stirring halfway through.

HOW CAN I CUSTOMIZE THE SPICE LEVEL OF THIS DELICIOUS RECIPE?

For milder fajitas, use a mild fajita seasoning and skip the green chilies. To turn up the heat and satisfy your taste buds, add a few sliced jalapeños, a pinch of cayenne pepper, or serve with your favorite hot sauce.

WHAT’S THE BEST WAY TO REHEAT LEFTOVER CHICKEN FAJITAS?

Reheat leftovers in a skillet over medium heat until warmed through, or microwave in short intervals. Add a splash of chicken broth if needed to keep the chicken and veggies moist.
