Pro Tips

• For a deeper flavor, use chicken thighs instead of breasts. They contain more fat and will result in an even more tender, juicy shred.
• Don’t skip the final sauté step! This is key to toasting the spices and ensuring the chicken is coated in flavor rather than just sitting in liquid.
• Make a double batch for meal prep. The shredded chicken stores beautifully in an airtight container in the refrigerator for up to 4 days.
• Elevate your tostadas with toppings like fresh cilantro, sliced avocado, cotija cheese, a dollop of sour cream, or a generous squeeze of lime juice.
