Before you start

Before beginning, ensure your slow cooker insert is clean and dry. Open the can of black beans and rinse them thoroughly under cold running water in a colander to remove excess sodium and starch.

If your chicken breasts are very thick, you may choose to pound them to an even thickness, though this is optional. Have your taco seasoning packet and salsa jar ready nearby to expedite the assembly process, ensuring you can get the slow cooker started in just a few minutes.

Ingredients at a glance (4)
  • 1 1/2 lb chicken breasts
  • 1 can black beans, drained and rinsed
  • 1 packet taco seasoning
  • 16 oz jar salsa

Instructions

Assembly and layering

  1. Assemble the ingredients
    Place the raw chicken breasts into the bottom of the slow cooker. If you choose to rinse the chicken, do so carefully to avoid splashing water onto surrounding surfaces, then immediately clean and sanitize the sink, colander, and any surfaces touched. Scatter the rinsed black beans over the chicken, then sprinkle the taco seasoning packet evenly across the top. Pour the entire jar of salsa over the ingredients to ensure everything is well-coated.
    Look for Ingredients should be layered evenly to ensure proper flavor distribution during the cooking process.
    Tip Ensure the chicken breasts are placed in a single layer at the bottom for even heat contact.

At this phase, the ingredients should be neatly layered in the slow cooker with the chicken at the base. The salsa should be poured over the top, creating a flavorful bath for the proteins and beans. Ensure no ingredients are left dry on top of the pile, as this could lead to uneven seasoning distribution. Everything should look ready for the slow, steady transformation that will occur over the next several hours.

Slow cooking process

  1. Slow cook the chicken
    Cover the slow cooker and set to cook on low for 4 to 6 hours, or on high for 2 to 3 hours, until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
    Look for The chicken is ready when it is completely opaque and easily pulls apart with a fork.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Avoid lifting the lid during the first few hours to maintain a consistent cooking temperature.

During the cooking phase, the slow cooker will emit a savory, spiced aroma that fills the kitchen. The chicken will slowly release its juices, which combine with the salsa to form a rich, aromatic sauce.

You should hear the soft bubbling of the liquid as the temperature rises. Avoid the temptation to open the lid frequently, as this releases essential heat and steam necessary for the cooking process to complete successfully.

Shredding and final seasoning

  1. Shred and serve
    Once cooked, remove the chicken breasts to a plate and shred them using two forks. Return the shredded meat to the slow cooker and toss with the cooking juices until thoroughly coated. Let the mixture rest for 5 minutes before serving to allow the flavors to meld.
    Look for The chicken should be glossy and fully coated in the thickened salsa and bean mixture.
    Tip If the sauce is too thin, leave the lid off for the last 30 minutes of cooking to reduce the liquid.

The final phase involves shredding the tender chicken and mixing it back into the flavorful sauce. The chicken should pull apart with minimal resistance, appearing soft and fully saturated. Once tossed, the mixture should look cohesive, with the beans and salsa clinging to the shredded meat. If the sauce appears too thin, you can leave the lid off for a short time to allow it to thicken to your desired consistency.

Common mistakes

A common mistake is overcooking the chicken, which can lead to a dry or stringy texture. While the slow cooker is forgiving, it is important to check the internal temperature once the minimum cooking time has elapsed.

Another error is not draining and rinsing the black beans, which can add a metallic taste or excessive starch to the sauce. Ensure the chicken is fully submerged or at least well-coated to prevent uneven cooking during the long heat cycle.

How to tell it’s done

The chicken is done when it is fully opaque throughout and reaches an internal temperature of 165°F (74°C). You should be able to shred the meat easily with two forks.

If the chicken still feels firm or resists being pulled apart, continue cooking for an additional 20 minutes before testing again. The final dish should appear glossy and moist, with the shredded chicken well-incorporated into the warm salsa and bean mixture.

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