• 3 cloves garlic, minced
• 2 tbsp olive oil
• 1/4 cup chicken broth or water
• 1/4 cup fresh lime juice, about 2 limes
• 2 tsp chili powder
• 1 tsp ground cumin
• 1 tsp smoked paprika
• 1 tsp onion powder
• 1/2 tsp garlic powder
• 1/2 tsp dried oregano
• 1 tsp kosher salt, or to taste
• 1/4 tsp black pepper
• 1/4 tsp crushed red pepper flakes or cayenne, optional but nice
• 8 to 12 small flour or corn tortillas (6 to 8 inch)
• 1/2 cup chopped fresh cilantro for serving
• 2 to 3 limes for serving
• 1 cup shredded cheddar or Mexican blend cheese, optional
• 1/2 cup sour cream or Greek yogurt, optional
• 1 to 2 avocados or 1 cup guacamole, optional
• Salsa, to taste, optional

How to Make this

1. Prep everything: thinly slice the 3 bell peppers and the large yellow onion, mince the 3 garlic cloves, juice 2 limes (reserve 1 for serving), chop the cilantro, and have the tortillas ready to warm later.

2. In a small bowl mix 2 tsp chili powder, 1 tsp cumin, 1 tsp smoked paprika, 1 tsp onion powder, 1/2 tsp garlic powder, 1/2 tsp dried oregano, 1 tsp kosher salt, 1/4 tsp black pepper and 1/4 tsp crushed red pepper flakes if using.

3. Put the 2 lb chicken breasts in the slow cooker, drizzle with 2 tbsp olive oil, pour in 1/4 cup chicken broth or water and 1/4 cup fresh lime juice, add the minced garlic and the spice mix, then rub everything over the chicken so it’s well coated.

4. Pile the sliced peppers and onion on top of the chicken, you dont need to stir, theyll steam down and flavor the chicken.

5. Cook on LOW for 4 to 6 hours or on HIGH for 2 to 3 hours, until the chicken reaches 165F and is falling apart tender.

6. Remove the chicken to a board, shred with two forks, then return the shredded chicken to the crock pot and stir into the juices and softened peppers so it soaks up the flavor; taste and add more salt or squeeze in the reserved lime if you want it brighter.

7. Warm 8 to 12 tortillas: heat them in a dry skillet 20 to 30 seconds per side, wrap in foil and keep warm, or stack and microwave covered with a damp paper towel for 30 to 45 seconds. If using cheese sprinkle about 1 cup shredded cheddar or Mexican blend on the hot tortillas or on the chicken so it melts.

8. Build the fajitas: spoon chicken and peppers into each tortilla, top with chopped cilantro, a squeeze of lime, and any of the optional toppings you like such as 1/2 cup sour cream or Greek yogurt, 1 to 2 sliced avocados or 1 cup guacamole, and salsa to taste.

9. Serve right away with extra lime wedges, more cilantro if you want, and enjoy. If you want more charred flavor next time, quickly sear the breasts in a hot skillet 1 minute per side before putting them in the crock pot, but it works great without that too.

Equipment Needed

1. Slow cooker (4 to 6 qt crock pot) for the chicken to cook falling-apart tender
2. Cutting board — big enough for peppers and the onion
3. Sharp chef’s knife for slicing and mincing (dont skimp on sharpness)
4. Measuring spoons + 1/4 cup liquid measure (for spices, oil, broth and lime juice)
5. Small bowl and spoon to mix the spice blend
6. Two forks (for shredding) and a pair of tongs to move the chicken/veggies
7. Large skillet or griddle to heat tortillas (or a microwave-safe plate and a damp paper towel)
8. Aluminum foil or a clean kitchen towel to wrap and keep tortillas warm, plus a large spoon to stir shredded chicken back into the juices

FAQ

Crock Pot Chicken Fajitas Recipe Substitutions and Variations

• Chicken breasts
  • Chicken thighs — juicier and more forgiving, you wont dry them out as easily; use same cook time and shred if you want.
  • Rotisserie or leftover cooked chicken — shred and stir in during the last 30 to 60 minutes so it warms through without getting rubbery.
  • Firm tofu or tempeh — cube and add in the last hour; tofu soaks up the fajita juices and tempeh gives a bit more texture.
  • White beans like cannellini or chickpeas — great if you want a vegetarian option, add for the last 30 to 45 minutes so they heat through.
• Bell peppers
  • Frozen pepper and onion mix — perfect for convenience, add frozen straight to the slow cooker; they’ll release extra water so drain a bit if you want.
  • Poblano or anaheim peppers — milder and earthy, good if you want a less sweet flavor.
  • Zucchini or summer squash — slice and add in last hour for a lighter veg option that wont get soggy.
  • Extra onion plus a splash of soy sauce — if peppers are out, onion gives sweetness and soy adds umami to balance.
• Chicken broth or water
  • Vegetable broth — keeps it vegetarian friendly and adds more flavor than plain water.
  • White wine — use a splash for bright acidity, but only a quarter cup and add with the lime so it cooks off a bit.
  • Beer such as a light lager — gives a subtle malt note that pairs well with smoked paprika and cumin.
  • Tomato sauce or salsa — swap part or all for salsa to make it saucier and more Mexican in flavor, reduce added salt accordingly.
• Fresh lime juice
  • Fresh lemon juice — very similar bright acid, just a slightly different citrus note.
  • Apple cider vinegar — use sparingly about half the amount for acid without extra citrus flavor.
  • Store bought lime juice — ok in a pinch, but taste first because strength varies, you might need a little more.
  • Lime zest plus a splash of water — if you ran out of juice, the zest adds aroma and a bit of tang when combined with a little water.

Pro Tips

– Sear the chicken first if you want extra flavor. Pat the breasts dry so they brown, heat a skillet very hot, and give them about 45 to 90 seconds per side. It adds a nice crust and more depth to the slow cooker juices, but dont leave them in the pan until cooked through.

– If you like your peppers with a bit more bite wait to add them. Toss them in for the last 30 to 60 minutes of cooking instead of putting them on top at the start, that way they keep some texture and bright color.

– Shred fast with a stand mixer when the chicken is hot. Put the warm pieces in the bowl, use the paddle on low for 15 to 30 seconds and stop when you like the size. Saves time and gives more consistent shreds than two forks.

– Always finish by tasting and adjusting. Warm the shredded chicken with a splash of the cooking liquid, then squeeze the reserved lime and add salt if it needs it. Tortillas heat better when wrapped in foil or a damp towel so they stay soft, and cheese melts much nicer on something piping hot.
