Before you start

Before starting, verify that the slow cooker is clean and properly positioned on a heat-resistant surface away from any edges. Ensure the chicken breasts are thawed completely if they were previously frozen, as cooking from frozen can lead to uneven temperatures.

Prepare the bell peppers by washing them thoroughly, removing the seeds and stems, and slicing them into uniform strips. Having all ingredients measured and ready before beginning the assembly process will ensure a smooth, efficient cooking experience from start to finish.

Ingredients at a glance (4)
  • 1 1/2 lb boneless, skinless chicken breasts
  • 2 cups bell peppers, sliced
  • 1 packet fajita seasoning
  • 1 cup salsa con queso dip

Instructions

Layering the ingredients

  1. Prepare the slow cooker
    Place the raw chicken breasts into the bottom of the slow cooker, ensuring they are spread out in an even layer to promote consistent cooking throughout the process.
    Look for Chicken is arranged on the bottom.
    Tip Avoid overcrowding the slow cooker to ensure the heat circulates properly around the meat.

The raw chicken sits flat on the base of the slow cooker, completely covered by a colorful layer of sliced bell peppers. The spices should be evenly distributed across the surface, preparing the dish for seasoning during the subsequent cooking phases.

Simmering to tenderness

  1. Add aromatics and seasonings
    Scatter the sliced bell peppers over the chicken breasts. Sprinkle the fajita seasoning evenly over the peppers and chicken to ensure every piece is well-coated with the spices.
    Look for Peppers are distributed over the chicken.
    Tip Uniformly slicing the peppers helps them cook at the same rate as the chicken.

The chicken releases its natural juices into the melting queso sauce, creating a rich, fragrant aroma of toasted spices and peppers throughout the kitchen. A steady, gentle simmer should be visible beneath the glass lid without excessive bubbling or steam loss.

Shredding and finishing

  1. Add sauce and cook
    Pour the salsa con queso dip over the top of the ingredients. Cover and cook on low for 4 to 6 hours or high for 2 to 3 hours until the chicken reaches 165°F (74°C). Shred the chicken directly in the pot, stir to combine with the creamy sauce, and let it rest for 5 minutes before serving.
    Look for Chicken is tender and pulls apart easily with a fork.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Use two forks to shred the chicken directly in the pot for easier cleanup.

The meat pulls apart effortlessly into tender shreds that quickly absorb the warm cheese sauce, creating an evenly coated, creamy mixture. The bell peppers should be tender yet intact, providing bright visual contrast throughout the thick, savory sauce.

Common mistakes

A common mistake is failing to verify the internal temperature of the chicken, which can lead to undercooked or overcooked meat.

Avoid lifting the lid frequently during the cooking process, as this releases heat and moisture, significantly extending the required cooking time.

Additionally, ensure the chicken is not packed too tightly, which allows for even heat distribution and prevents the cheese sauce from scorching at the bottom of the slow cooker.

How to tell it’s done

The chicken is fully cooked when it reaches an internal temperature of 165°F (74°C) measured with a food thermometer at the thickest part of the breast.

At this point, the meat should be opaque throughout and shred easily with a fork. It is important to confirm this temperature to ensure safety and quality, as the chicken should be succulent and tender rather than dry or rubbery.

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