Before you start
Before starting, ensure your slow cooker is placed on a stable, heat-resistant surface away from the edge of the counter. Prepare the onion by slicing it into thin half-moons, which helps them soften and melt into the sauce during the cooking process.
Keep the chicken refrigerated until you are ready to assemble the slow cooker to maintain proper food safety standards. Have your measured spices and broth ready to go so that assembly is quick and efficient.

- 3 lb boneless skinless chicken thighs
- 1 medium yellow onion, sliced into half-moons
- 2 tbsp birria spice blend
- 2 cups red chile broth
Instructions
Preparation and Layering
- Prepare the Slow CookerPlace the boneless skinless chicken thighs into the bottom of the slow cooker, arranging them in a single layer so they cook evenly. Scatter the onion half-moons over the chicken, ensuring they are distributed to provide aromatic depth during the long, slow braising process.Look for Chicken thighs are tiled edge to edge in the insert.Tip Ensure the chicken is raw and cold from the refrigerator for food safety.
At the end of this phase, the chicken thighs should be arranged neatly in the slow cooker with the onions distributed on top. The ingredients should look organized and ready for the seasoning. Ensure that the slow cooker is plugged in and ready to be set to the appropriate heat level before moving on to the seasoning stage.
Slow Braising
- Season and BraiseEvenly dust the birria spice blend over the chicken and onions. Pour the red chile broth over the top of the ingredients. Cover the slow cooker and cook on low for 6 to 8 hours, or on high for 3 to 4 hours, until the chicken reaches an internal temperature of 165°F (74°C).Look for The broth is poured over the spices and chicken.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Do not remove the lid during the cooking process to maintain the internal temperature.
During this phase, the kitchen will begin to fill with the savory aroma of the spices and onions. The chicken will gradually transform from raw to tender as it braises in the red chile broth.
By the end, the meat should look opaque and the onions should be soft and translucent, indicating that the flavors have successfully melded together.
Shredding and Finishing
- Shred and ServeOnce the chicken is fully cooked, carefully remove the thighs from the slow cooker and shred them using two forks. Return the shredded chicken to the sauce to coat thoroughly before serving warm on a plate. Let the dish rest for 5 minutes before portioning.Look for The chicken is falling apart and coated in thick red sauce.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Check the internal temperature again if you are unsure of the doneness.
After shredding, the chicken should be completely coated in the thick, flavorful sauce. The texture should be uniform, with no large chunks of meat remaining. The final dish should be steaming hot and ready to be served immediately, having reached the required internal temperature for safe consumption.
Common mistakes
A common mistake is using chicken breasts instead of thighs; breasts are leaner and will likely dry out during the long cook time, resulting in a stringy texture.
Another error is failing to ensure the chicken is arranged in a single layer, which can cause uneven cooking. Do not open the slow cooker lid frequently, as this causes significant heat loss and extends the cooking time, which can lead to a less consistent final result.
How to tell it’s done
The chicken is considered done when it reaches an internal temperature of 165°F (74°C). At this point, the meat should be extremely tender and easily pull apart with the pressure of a fork.
The sauce will have thickened slightly and will be a deep, vibrant red color. If the chicken still feels firm or resists shredding, continue cooking for an additional 30 minutes, as the connective tissue needs more time to break down properly.
