Clean the chicken thighs and layer in a single layer for seasoning.
Combine the seasoning in a bowl and apply liberally over the chicken thighs.
Add the onion slices and garlic to the bottom of a baking dish.
Layer the chicken thighs in the dish on top of the onions and garlic.
Add the chicken stock, cover tightly with aluminum foil, and put in the oven.
Cook in the oven for 1 hour to 1 hour 10 minutes. If you test the chicken, it should break apart easily when you press a fork on it.
Remove the cooked chicken from the baking dish with tongs, leaving the onions, garlic, and stock in the baking dish. Place it in a rimmed baking pan and shred with 2 forks.
Either serve hot and enjoy or allow to cool and store in the refrigerator for up to a week.
