Before you start
Before beginning, ensure that your slow cooker is clean and positioned on a stable, heat-resistant surface. Have all your ingredients measured and ready. Dice the onion and mince the garlic cloves ahead of time to keep the assembly process smooth.
Check that your corn tostadas are fresh and crisp, and prepare your garnishes, including dicing the avocado and mincing the cilantro, so they are ready to go the moment the chicken is finished and the cheese is melted.

- 3 lb boneless skinless chicken thighs
- 2 cups guajillo-ancho birria adobo sauce
- 1 onion, diced
- 4 garlic cloves
- 1 pinch cinnamon
- 1 tsp dried oregano

Instructions
Layering the slow cooker
- Prepare the slow cookerPlace the boneless skinless chicken thighs into the basin of the slow cooker. Pour the guajillo-ancho birria adobo sauce over the chicken. Add the diced onion, minced garlic cloves, a pinch of cinnamon, and the dried oregano. Ensure the chicken is evenly coated with the aromatics and sauce, then cover with the lid.Look for The chicken should be fully submerged or well-coated in the birria liquid.Tip Ensure the chicken thighs are trimmed of excess fat before adding them to the pot for the best texture.
The chicken should be evenly arranged in the slow cooker, fully coated by the adobo sauce and aromatics. Everything should be layered neatly, and the lid must be secured tightly to ensure consistent heat distribution. If the chicken is not fully covered by the sauce, gently shift the pieces until they are better positioned. This initial setup is vital for developing the deep, rich flavors during the long, slow simmer.
Slow-cooking and shredding
- Slow cook and shredSet the slow cooker to the LOW setting and cook for four and a half hours. Once the time is up, remove the chicken thighs from the pot and shred them thoroughly using two forks on a clean cutting board. Return the shredded chicken to the ruby broth in the slow cooker and stir to combine well, ensuring the chicken reaches a safe internal temperature of 165°F (74°C).Look for The chicken is ready when it pulls apart easily with minimal pressure from a fork.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Shred the chicken while it is still warm to allow it to absorb the maximum amount of flavor from the cooking liquid.
After four and a half hours, the kitchen should smell intensely fragrant and smoky. The chicken will look dark, tender, and saturated with the red adobo sauce. When tested with a fork, the meat should offer almost no resistance and fall apart easily. This is the moment to remove the chicken to a board, shred it thoroughly, and return it to the pot to integrate with the juices before the final step.
Melting and assembly
- Melt cheese and assembleSprinkle the shredded Oaxaca cheese over the chicken mixture in the slow cooker. Cover the lid again and allow the cheese to melt into the hot chicken mixture for about five minutes. Assemble the tostadas by piling the cheesy chicken mixture onto the crispy corn tostada shells. Garnish with diced avocado, a drizzle of Mexican crema, minced cilantro, and a squeeze of fresh lime juice just before serving.Look for The cheese should be completely melted and stretchy before you begin assembly.Tip Assemble the tostadas immediately before serving to keep the shells as crisp as possible for the best dining experience.
The mixture should look glossy and vibrant with the cheese creating long, satisfying pulls. The chicken and cheese should be thoroughly combined.
Once assembled on the tostadas, the dish should look colorful and fresh, with the bright green avocado and cilantro contrasting against the deep crimson chicken. The tostadas must be served immediately to ensure the shells remain crunchy and the cheese stays warm and soft for the best eating experience.
Common mistakes
A common mistake is overcrowding the slow cooker, which can prevent even cooking. Ensure there is enough space for the chicken to be submerged in the sauce.
Another error is failing to shred the chicken properly; taking the time to pull it into fine strands ensures that it absorbs the maximum amount of flavor. Finally, adding the cheese too early can cause it to separate or become rubbery, so always wait until the final five minutes of cooking.
How to tell it’s done
The chicken is done when it is fully cooked to an internal temperature of 165°F (74°C) and shreds easily with two forks. The broth should be rich, fragrant, and slightly thickened.
The Oaxaca cheese must be fully melted and stretchy throughout the chicken mixture, creating a uniform, indulgent consistency. If the chicken still resists shredding, continue cooking for another twenty minutes on the low setting before checking again.
