Pat the chicken dry, then season all over with salt, pepper, garlic powder, and onion powder.
Add the broth and bay leaf to a large pot or deep skillet. Nestle the chicken in a single layer.
Bring to a gentle simmer over medium heat. Cover and cook for 15 to 20 minutes, until the chicken reaches 165°F in the thickest part and is tender.
Transfer chicken to a bowl and let rest for 5 minutes. Shred using two forks or a hand mixer on low speed.
Return shredded chicken to the pot with a few spoonfuls of the cooking liquid. Toss over low heat for 2 to 3 minutes to absorb flavor.
Taste and adjust seasoning as needed. Serve or cool completely for meal prep.
Notes
For extra flavor, add a pinch of cumin or a splash of lime juice. Store in an airtight container in the refrigerator for up to 4 days or freeze up to 3 months. Reheat gently with a bit of broth to keep it moist.
