Put the boneless, skinless chicken breasts in a single layer at the bottom of your Dutch oven.
1-1.5 pounds boneless skinless chicken breasts
Scatter the onion, garlic, bay leaf, salt, pepper, and other spices over the chicken breasts.
1 medium onion, 2-3 cloves garlic, 1 bay leaf, 1 teaspoon salt, 1 teaspoon whole peppercorns, 1 teaspoon dried oregano, ⅛ teaspoon red pepper flakes
Pour enough water or chicken broth into the Dutch oven to cover the chicken by about an inch.
water or chicken broth to cover
Cover and place the Dutch oven on the stove top over low heat. Slowly bring the liquid to the gentlest simmer with a goal liquid temperature of 170 to 180°. Poach until the chicken reaches an internal temperature of 165°F (74°C), about 30 to 40 minutes.
Once the chicken is fully cooked, use tongs to remove it from the poaching liquid and place it on a cutting board. Let it cool for a few minutes, then use your hands, two forks, or even a mixer to pull the chicken into bite-sized shreds.
Serve as is, or return the pulled chicken back to your Dutch oven and add your favorite BBQ or other sauce. Stir the sauce in over low heat until your chicken is coated thickly and warmed through.
