Remove the skin from the chicken thighs, then cut the thighs into halves. One half will be boneless and the other will be bone-in. You do not need to cut through the bones.
Season the thighs with green seasoning, salt, black pepper, paprika, cassareep and tomato paste and dried thyme (if using) and let marinade for at least 30 mins before cooking.
When ready to cook heat a large pot on medium heat. When the hot is hot add the oil and when the oil is hot add the onions. Cook for a minute or two or until the onions become a little see through. Then add the garlic and the brown sugar. Stir to combine and cook until the sugar starts to caramelize and the onions get brown.
Next add the diced tomatoes and cook until they are soft and mushy (about 3-5 minutes). The add the marinaded chicken. Stir to combine. Then increase the heat to high. Cook on high heat for 10 to 15 minutes stirring often to avoid burning. Continue to cook until all of the liquids cook off.
Then add in the potatoes and carrots. Mix to combine and continue to cook for another 5 minutes, stirring every often to avoid sticking.
Next, add 4 cups of water or chicken stock if you like, cover, reduce the heat to medium and cook until the potatoes are soft, this can take up to 30 minutes, depending on how long it takes for your potatoes to cook to a fork tender stage.
Once the potatoes cook you may reduce the heat to low and continue to simmer until the stew thickens or if you are in a rush, increase the heat to high to quickly reduce the sauce, but keep on eye on it before it burns.
