Ingredients

All you need are a few simple ingredients and your slow cooker!

• 1 ½ to 2 pounds boneless, skinless chicken breasts (or thighs)
• 3 bell peppers, sliced (mix of red, green, and yellow for color)
• 1 medium onion, thinly sliced
• 1 can (14.5 oz) diced tomatoes, drained (fire roasted, plain, or with green chilis)
• Homemade Fajita Seasoning
• Juice of 1 lime (optional)
• Fresh cilantro (optional)

Optional toppings: avocado, cilantro, Greek yogurt or sour cream, shredded cheese, salsa, fresh lime wedges.

Instructions

1. Layer the veggies: Place sliced bell peppers and onions at the bottom of the slow cooker.

2. Add the chicken: Lay the chicken breasts on top of the veggies.

3. Season generously: In a small bowl, mix the fajita spices together. Sprinkle evenly over the chicken.

4. Top with tomatoes: Pour the can of diced tomatoes over everything.

5. Cook: Cover and cook on low for 5-6 hours or high for 3–4 hours, until the chicken is tender and easily shreddable.

6. Shred the chicken: Remove the chicken, shred it with two forks, and return it to the slow cooker. Stir everything together.

7. Add lime juice: Just before serving, squeeze fresh lime juice over the mixture to enhance flavor.

Variations and Add-Ins

• Add beans or corn: For extra fiber and flavor, stir in a can of black beans or corn after cooking.

• Make it creamy: Mix in a few tablespoons of cream cheese or sour cream at the end for a creamy fajita filling.

• Try different proteins: Swap chicken for sliced flank steak or shrimp (adjust cooking time for shrimp).

• Make it spicy: Add extra cayenne, a diced jalapeño, or a splash of hot sauce to the slow cooker.

How to Serve Crockpot Chicken Fajitas

• Traditional: Serve in warm tortillas with your favorite toppings — avocado, sour cream, shredded cheese, cilantro, salsa, or jalapeños.

• Low-carb: Spoon over cauliflower rice or wrap in lettuce cups.

• Fajita bowls: Build a bowl with rice or quinoa, beans, greens, and the fajita mixture.

• Stuffed peppers: Use leftovers to fill bell peppers and bake for a second delicious meal.

Frequently Asked Questions

Can I use frozen chicken?

Yes — you can use frozen chicken breasts but be sure to increase the cooking time slightly. Make sure the chicken reaches an internal temperature of 165°F.

Can I make this ahead of time?

Absolutely! This is a great meal prep recipe. You can chop all the veggies and mix the spices in advance or even freeze everything raw in a zip-top bag to dump into the slow cooker later.

Do I have to sauté the vegetables first?

Nope! The slow cooker takes care of everything. The peppers and onions will soften and sweeten as they cook.

How do I store and reheat leftovers?

Store in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or on the stovetop until warmed through. The mixture also freezes well for up to 3 months.

What if I don’t have diced tomatoes?

You can use fresh tomatoes, tomato sauce, or even salsa as a substitute — just make sure there’s some moisture to help the chicken stay tender.

Is this recipe spicy?

Not by default! It’s mildly spiced for flavor but not heat. If you like things spicy, add jalapeños, extra chili powder, or hot sauce when serving.
