How to make crockpot chicken fajitas

  • First, make the chicken fajitas marinade. In a small mixing bowl, whisk oil, chili powder, garlic powder, onion powder, smoked paprika, cumin, juice of one lemon, zest of one lemon, black pepper, and kosher salt.
  • Next, marinate the chicken. Place the chicken breasts into a large resealable plastic bag and add the marinade mixture over the chicken. Seal the bag tightly, then stir through to evenly coat the chicken with the marinade. Marinate in the fridge for at least one hour or overnight.
  • Prep the veggies. Cut the onion and peppers into 1/2 inch thick slices.

  • Add to slow cooker. In a 6 quart crockpot, add the marinated chicken. Then pour orange juice on top. Next, add chopped onion and bell peppers on top of the chicken. If you prefer the peppers more on the firm side, hold off on adding the peppers until 30 minutes before the final cook time.
  • Then, cook. Cover the pot with the lid and cook on HIGH for 4 – 5 hours or until the internal temperature reads 165 degrees F.

  • Garnish and serve. Add a squeeze of half a lime juice and garnish with fresh cilantro leaves and lime wedges. Serve fajitas in tortillas with your desired toppings.

Tips and substitutions

  • Seasonings: These fajitas get all their flavor from the seasonings, so we don’t suggest skipping any. If you need to use regular paprika instead of smoked you can. However, the smoked will add more flavor.
  • Bell peppers: You can substitute the red peppers for yellow or orange. Do not put the peppers at the bottom under the chicken. If you prefer the peppers to be a bit on the firm side, hold off on adding them until 30 minutes before the end of cook time.
  • Onion: You can substitute the red onion for a white or yellow onion.
  • Lime juice: For best results, use freshly squeezed lime juice and fresh lime zest.
  • Gluten-free option: You can use gluten-free tortillas, or alternatively you can serve chicken fajitas over a bowl of quinoa or brown rice for a gluten-free dinner.
  • Marinate longer for more flavor: To get the most flavor, marinate the chicken overnight or for several hours before cooking.

Faqs

Can I put raw chicken in the Crockpot?

Absolutely! You put the raw marinated chicken in the slow cooker and allow it to cook for several hours until it has cooked through, or until has reached an internal temperature of 165°F.

How do I keep chicken from drying out in Crockpot?

The key to keeping the chicken tender and moist is to cook it until just cooked through, then slice. If you overcook the chicken, it will dry out.

What toppings do I serve on fajitas?

You can serve chicken fajitas with tortillas, chopped lettuce, shredded cheese, salsa, guacamole, or sour cream. Every topping is optional, so serve them however you like.

What sides do I serve with fajitas?

These chicken fajitas are plenty filling on their own, but if you want to serve them with sides we suggest this Healthy Mexican Street Corn or a simple red salsa with chips.

How long can you keep fajitas in the fridge?

Stored in a sealed container, these slow cooker chicken fajitas should last 5-7 days. You can reheat them in the microwave or oven, then serve with toppings.

      Yes. You can. I guess it would be best to slice the chicken first and add everything into the instant pot. Seal and set it on manual or pressure cook on high for 5 minutes and then do a quick release

    Hi, we are making these today but it’s not clear about the lime juice and zest. I assume it’s to be added with the orange juice but the directions don’t state anything about the lime other than add a squeeze at the end which to me implies another lime? The picture then shows lime slices in the crock so you might want to clarify. The marinate was more like a paste so I added a second tablespoon of oil and a bit of water to thin it out. Looking forward to how it turns out.
