What You’ll Need

900 g boneless, skinless chicken breasts
410 g canned petite diced tomatoes with green chilies
3 bell peppers (1 red, 1 yellow, 1 green), cored and sliced
1 large yellow onion, halved and sliced
4 garlic cloves, minced
6 g chili powder (2½ teaspoons)
4 g ground cumin (2 teaspoons)
2 g paprika (1 teaspoon)
1.5 g ground coriander (¾ teaspoon)
5 g salt (1 teaspoon)
3.5 g pepper (¾ teaspoon)
30 ml fresh lime juice (2 tablespoons)
15 ml honey (1 tablespoon)

For Serving:

12 flour tortillas (15 cm)
Optional toppings: cilantro, sour cream, salsa, guacamole, or sliced avocados, shredded Mexican cheese

How to Make Slow Cooker Chicken Fajitas

Pour half of the diced tomatoes into the bottom of a 6-quart (5.7-liter) slow cooker, spreading them out.
Layer half of the sliced bell peppers and onions over the tomatoes, then sprinkle the minced garlic.
Place the chicken breasts on top.
In a small bowl, mix the chili powder, cumin, paprika, coriander, salt, and pepper. Sprinkle half the seasoning mix over the chicken, flip it, and sprinkle the rest.
Add the remaining diced tomatoes, peppers, and onions on top.
Cover and cook on high for 2–3 hours or low for 4–6 hours until chicken is cooked and veggies are soft.
Remove the chicken and slice or shred it.
Discard about 240 ml (1 cup) of the broth.
Whisk the lime juice and honey, then stir them into the slow cooker along with the chicken. Add more salt to taste and cilantro if you like.
Serve warm in tortillas with your favorite toppings.

Foolproof Tips for Flavorful Fajitas

Want more charred flavor? Give the sliced peppers a quick sauté before adding them to the slow cooker.
Don’t skip the honey and lime—they’re the secret to that crave-worthy tangy-sweet balance.
Using frozen chicken? Just add extra cook time and be sure it’s cooked through before serving.

My Fajita Epiphany

This recipe came to life during a week when I had zero bandwidth but still wanted something that tasted like love in a tortilla. I tossed everything in the slow cooker before a busy workday, and when I got home? Pure magic. The aroma alone had my kids racing to the table, and it quickly became our “any night is a fiesta” dinner. Trust me, these chicken fajitas will become a regular in your rotation.

Serving Suggestions for the Perfect Fajita Night

Pile the shredded chicken and veggies into warm flour tortillas. Add your favorite toppings: creamy guac, a dollop of sour cream, a sprinkle of shredded cheese, and a few cilantro leaves if you’re feeling fancy. Want to skip the tortilla? Try it over a bed of rice, stuffed into a baked sweet potato, or on top of a crisp salad for a healthy slow cooker dinner that’s still full of flair.

How to Store and Reheat Like a Pro

Store leftovers in an airtight container in the fridge for up to 4 days. This dish also freezes well for up to 2 months. Just reheat on the stove or in the microwave with a splash of the reserved broth to keep things juicy. It’s perfect for meal prep lunches or quick weeknight repeats.

Is this a healthy slow cooker dinner?

Yep! It’s packed with lean protein, veggies, and bold spices. Use whole wheat tortillas for an extra fiber boost.

Totally. Chop everything the night before and refrigerate until you’re ready to start cooking.
