Set a pan on the stove top and set to medium-high heat. Add the cooking oil and swirl coat the bottom of the pan. When the oil is hot, brown the chicken on both sides, you don't need to cook the meat through.
Add the diced potatoes and green beans to the bottom of the slow cooker, toss them together to combine them.
Add the chicken thighs on top of the potatoes and green beans. Add the garlic. Drizzle over the tomato sauce, then sprinkle over the salt, pepper, thyme, and rosemary. Take a spatula and smear around the sauce trying to combine the seasoning into the sauce.
Cover and cook on HIGH for 4.5 hours. Do no open the lid during the cooking time or the potatoes will not get tender.
Serve and enjoy!
If you desire to use boneless skinless chicken add a cup of chicken broth. Any type of potato can be used in place of the Yukon gold potatoes.Nutritional Values are approximate. Please use your own calculations if you require a special diet. The values below are for 1/4 of the recipe.
