Before you start
Before beginning, ensure all ingredients are ready and measured. Take the chicken out of the refrigerator just before you are ready to assemble the pot. Have your slow cooker placed on a stable, heat-resistant surface near an electrical outlet.
Ensure you have two forks ready for the final shredding step, as this is the most efficient way to achieve the desired texture. Keep your serving plates warm if possible, and have your chosen sides, such as cooked rice or tortillas, prepared or warming while the chicken finishes its final stage of the cook.

- 1.5 lb chicken breasts
- 2 cups sliced peppers and onions
- 1 packet taco seasoning
- 14.5 oz crushed tomatoes
Instructions
Assembly Phase
- Prepare the Slow CookerPlace the raw chicken breasts into the bottom of the slow cooker. Scatter the sliced peppers and onions evenly over the top of the chicken to ensure even cooking and flavor distribution throughout the cooking process.Look for Chicken is arranged in a single layer at the base.Tip Ensure the chicken is raw and cold from the refrigerator.
During this phase, ensure the chicken is placed flat at the bottom of the slow cooker. The peppers and onions should be scattered evenly to provide uniform coverage. Once the seasoning and tomatoes are added, the pot should look full but not overflowing. Check that the lid is placed securely to create an airtight seal, which is essential for the slow cooking process to begin effectively without losing steam or moisture.
Cooking Phase
- Add Seasoning and TomatoesSprinkle the taco seasoning packet over the layer of peppers and onions. Pour the crushed tomatoes over the top, covering the ingredients completely to create a flavorful braising liquid while the chicken cooks slowly.Look for The tomatoes should cover most of the ingredients.Tip Do not stir the pot; let the ingredients layer as instructed.
As the cooking progresses, you will notice a pleasant, savory aroma filling the kitchen. The crushed tomatoes will begin to break down, releasing their juices to mix with the spices. The peppers and onions will soften and become translucent.
Check the slow cooker periodically to ensure it is maintaining a steady heat. The liquid level should be sufficient to keep the chicken moist without completely submerging the top layer, which helps maintain the integrity of the vegetable texture.
Shredding and Finishing
- Cook and ShredCover and cook on low for 4 to 6 hours or high for 2 to 3 hours until the chicken is tender. Ensure the chicken reaches an internal temperature of 165°F (74°C) before shredding the meat directly in the pot with two forks. Let the meat rest for 5 minutes before serving.Look for Chicken shreds easily with a fork.Safe temperature 165°F (74°C) internal temperature (poultry)Tip If the sauce is too thin, you can simmer it on high with the lid off for 15 minutes.
Once the cooking time is complete, the chicken should be very tender and easily pulled apart. The sauce should be thickened and aromatic, clinging to the meat. Shred the chicken thoroughly with two forks, ensuring the juices and seasonings are well incorporated into every strand. The final result should be a cohesive, saucy mixture that is hot and ready to serve immediately over your chosen base, with the chicken appearing moist and succulent throughout.
Common mistakes
A common mistake is overcrowding the slow cooker, which can prevent even cooking. Ensure the chicken is in a single layer at the bottom. Another error is lifting the lid too frequently during the cooking process; every time you open the lid, heat escapes, significantly increasing the total cook time.
Avoid adding unnecessary liquids like extra broth or water, as the tomatoes and vegetables provide sufficient moisture. Finally, ensure the chicken is completely thawed before starting, as cooking frozen poultry in a slow cooker can keep it in the food danger zone for too long.
How to tell it’s done
To confirm the chicken is done, use a digital meat thermometer inserted into the thickest part of the breast. The chicken must reach an internal temperature of at least 165°F (74°C). The meat should be opaque throughout and shred easily with the gentle pressure of a fork.
If the chicken still feels firm or resists shredding, continue cooking for another 20 minutes before checking again. Always allow the meat to rest for 5 minutes before serving to ensure the juices redistribute for optimal tenderness and flavor.
- Poultry: 165°F (74°C) in the thickest part
