¾ cup prepared salsa
4 teaspoons chili powder
2 teaspoons salt
2 teaspoons paprika
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon sugar
1 teaspoon cumin
¼ teaspoon oregano
2 pounds boneless, skinless chicken breasts or tenders
1 medium onion, sliced
1 medium red bell pepper, sliced
1 medium green bell pepper, sliced
Juice of 1 lime
Flour or corn tortillas
Optional toppings: pico de gallo, cilantro, shredded cheese, sour cream, guacamole

Directions

Mix the seasoning:
In a small bowl, combine the salsa, chili powder, salt, paprika, garlic powder, onion powder, sugar, cumin, and oregano. Stir well and set aside.
Assemble in the slow cooker:
Place chicken in the bottom of a 6-quart slow cooker. Pour the salsa-spice mixture over the chicken. Add the sliced onion and bell peppers on top.
Cook:
Cover with lid and cook on low for 4–6 hours or high for 3–4 hours, until chicken is fully cooked and tender. Note: chicken breasts may take longer than tenders.

Shred the chicken:
About an hour before finishing, stir everything gently to distribute the peppers and onions. Once done, remove the chicken and shred it with two forks.
Finish:
Return the shredded chicken to the crockpot, add lime juice, and stir to combine. Taste and adjust seasoning if needed.
Serve:
Use a slotted spoon or tongs to serve the chicken mixture in warmed tortillas. Add your favorite toppings and enjoy.

FAQs

Can I use frozen chicken in this recipe?

Yes, but it’s best to thaw it first for even cooking. Using frozen chicken directly can affect the cook time and texture.

Can I make this with chicken thighs?

Absolutely. Boneless, skinless thighs will be even more tender and flavorful.

Do I have to use salsa?

Salsa adds moisture and flavor, but you could substitute with crushed tomatoes or tomato sauce with added spices if needed.

Can I cook it longer?

Yes, you can cook on low up to 6 hours, but avoid overcooking or the chicken may become dry.

How do I keep the veggies from getting mushy?

For crisper vegetables, add the bell peppers halfway through cooking instead of at the beginning.

What kind of tortillas work best?

Both flour and corn tortillas work well—choose based on your preference. Warm them before serving for best texture.

Can I add beans or corn?

Yes, you can add a drained can of black beans or corn during the last hour of cooking for extra bulk and texture.

How do I serve the chicken if I don’t have tortillas?

Try it over rice, quinoa, salad greens, or in a burrito bowl with your favorite toppings.

Is this recipe gluten-free?

Yes, as long as you use gluten-free corn tortillas and check that your salsa is gluten-free.

Can I double the recipe?

Yes, you can double everything for a crowd. Just be sure your slow cooker is large enough to handle the extra volume.
