Before you start

Before you start, slice the bell peppers into strips and the red onion into thin wedges. Juice the limes to get 2 tablespoons of fresh juice.

Measure out the salsa, sour cream, and shredded cheese. Have your slow cooker ready and plugged in. There’s no need to preheat it; just place the ingredients inside in the order given.

Ingredients at a glance (7)
  • 6 boneless skinless chicken thighs
  • 3 mixed bell peppers (red, yellow, orange), sliced
  • 1 red onion, sliced into strips
  • 2 tbsp fresh lime juice
  • 1/2 cup sour cream
  • 1 1/2 cups shredded Monterey Jack cheese
  • 1 cup salsa (red or your favorite)

Instructions

Layer and Set

  1. Layer the Ingredients
    Place the chicken thighs in the bottom of the slow cooker in a single layer. Scatter the sliced bell peppers and red onion strips over the chicken. Drizzle with the lime juice.
    Look for The chicken should be mostly covered by the vegetables, but it's okay if some edges peek through.
    Tip For even cooking, try to arrange the chicken thighs so they aren't overlapping too much.
  2. Add the Salsa
    Pour the salsa evenly over the chicken and vegetables, spreading it gently with a spoon to coat everything. The salsa will create a braising liquid as it cooks.
    Look for The salsa should be evenly distributed, with some visible on the top.
    Tip Use a salsa you enjoy eating — its flavor will infuse the whole dish.
  3. Top with Cream and Cheese
    Dollop the sour cream over the top of the mixture, then sprinkle the shredded Monterey Jack cheese over everything. Do not stir; the layers will meld as they cook.
    Look for The sour cream and cheese should form a thick, creamy layer on top.
    Tip Leaving the sour cream and cheese on top prevents them from curdling or separating.

After this phase, the slow cooker contains a colorful mosaic: chicken thighs nestled under a pile of peppers and onions, with salsa, sour cream, and cheese piled on top. The ingredients are raw and separate, but the sour cream and cheese should form a neat layer, ready to melt into a sauce as the heat works its magic.

Slow Cook and Shred

  1. Cook on Low
    Cover the slow cooker and cook on low for 6 to 7 hours, or on high for 3 to 4 hours, until the chicken is tender and easily shreds with a fork. The sauce will be bubbling and the cheese melted.
    Look for The chicken should be cooked through and the sauce should be thick and creamy, with no raw flour or cheese lumps.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip If the sauce looks too thin at the end, remove the lid and cook on high for an additional 20-30 minutes to reduce.
  2. Shred the Chicken
    Using two forks, shred the chicken thighs directly in the slow cooker. Stir to combine the shreds with the peppers, onions, and creamy sauce. Taste and adjust seasoning if needed.
    Look for The chicken should shred easily and be coated in the creamy sauce.
    Tip If you prefer larger chunks, skip the shredding and serve the thighs whole.

The slow cooker has been bubbling away for hours. The aroma is rich and savory, with a hint of lime. The chicken is fork-tender, the peppers are soft, and the sauce has turned into a creamy, cheesy, salsa-infused gravy. The cheese is fully melted, and the sour cream has blended in, creating a glossy, cohesive sauce.

Serve and Savor

  1. Serve and Enjoy
    Spoon the hot fajita chicken mixture onto a serving plate or into bowls. Serve with warm flour tortillas, if desired. Enjoy immediately.
    Look for The dish should be steaming hot, with a rich, creamy sauce clinging to the chicken and vegetables.
    Tip Warm the tortillas in a dry skillet or microwave before serving for the best texture.

The shredded chicken and vegetables are coated in a thick, creamy sauce. When spooned onto a plate, the mixture holds together slightly, and steam rises from the surface.

The colors are vibrant: golden chicken, red and yellow peppers, and a creamy orange sauce. It’s ready to be wrapped in warm tortillas or served over rice.

Common mistakes

One common mistake is stirring the sour cream and cheese into the raw ingredients. This can cause the dairy to curdle and create a gritty texture. Another is overcooking the chicken, which can make it dry and stringy.

Stick to the recommended cooking times and use a meat thermometer to ensure accuracy. Also, avoid lifting the lid too often during cooking, as this lets out heat and extends the cook time.

How to tell it’s done

The dish is done when the chicken reaches an internal temperature of 165°F (74°C) and shreds easily with a fork.

The peppers should be tender but still have a little bite, and the sauce should be thick and creamy, with the cheese fully melted and smooth. If the sauce is too thin, remove the lid and cook on high for 20-30 minutes to reduce.

  • Poultry: 165°F (74°C) in the thickest part
