Add salsa and spices: Pour the salsa over everything, then add the minced garlic, paprika, cumin, salt, and black pepper. This is where all the flavor comes from.

Cook low and slow: Cover the slow cooker and cook on high for 3 to 4 hours or low for 6 to 7 hours, until the chicken shreds easily with a fork. The chicken should be tender and falling apart, and the peppers and onions should be soft.

Serve: Pile the shredded chicken fajitas into warm tortillas and top with your favorite toppings like guacamole, cilantro, pico de gallo, and cheese. Serve immediately while everything is hot and flavorful.

Serving Suggestions
In warm tortillas. Flour or corn tortillas both work beautifully. Warm them in a skillet or microwave before serving.
Over rice. Skip the tortillas and serve the fajitas over cilantro lime rice or plain white rice for a bowl-style meal.
In a salad. Pile the chicken and vegetables over lettuce, add some black beans, corn, and a drizzle of ranch or chipotle dressing.
As fajita bowls. Layer rice, Crockpot Chicken Fajitas, black beans, cheese, guacamole, and salsa in a bowl for a build-your-own fajita bar.
Top Tip
Don't overcook the chicken. Check it at the minimum cooking time. Overcooked chicken can get dry and stringy, even in a slow cooker.
Slice the vegetables evenly. This helps them cook at the same rate and ensures everything is tender at the same time.
Use fresh lime juice. The bottled stuff just doesn't have the same bright, fresh flavor. Squeeze it right before serving for the best taste.
Check your slow cooker's heat. Slow cookers vary a lot in how hot they run. If yours tends to cook fast, check the chicken earlier. If it's slower, give it extra time.
Let the chicken rest before shredding. If you pull it out and shred it immediately, it'll hold together better. If you wait too long, it can dry out.
Save the juices. Don't drain the liquid at the bottom. It's packed with flavor and keeps everything moist. Spoon it over the fajitas when you serve them.
