Season both sides on the chicken with liberal amounts of Cajun seasoning. Go a little lighter on the skin side (too much on the skin will make the "cracklins" too salty)
Heat oil in your large pot over medium-high heat
Once oil is hot, add seasoned chicken to the pot, skin side down.
Cook until skin is well-browned
Turn thighs over and cook until the other side is well browned.
Remove chicken from the pot.
After you remove chicken, remove the browned chicken skin from the thighs and place on a baking sheet
Reduce heat to low and add onions and bell pepper
Cook onions and bell pepper until they are nice and soft... almost like a paste
Add hot sauce and Worcestershire sauce to pot, stir well
Add water and bullion cubes and stir until cubes are fully dissolved
Add garlic and chicken back to the pot
Reduce heat to low and cook until water covers about 2/3 of the thighs
Stir and flip chicken thighs over occasionally to ensure even cooking of thighs
Cook low and slow until the "gravy" is low and has thickened a little. This usually takes 1 - 1.5 hours.
Broil the chicken skin, skin side down, for about 1.5 to 2 minutes
Enjoy!
