Heat a large 6-8 quart soup pot over medium heat and add the oil or butter.
Generously salt and pepper the chicken thighs on both sides and place them skin-side down in the pot.
Brown the chicken skin, then flip and cook for 3 more minutes.
Remove the chicken from the pot and set aside.
Add the chopped onions and minced garlic to the pot with the chicken fat; sauté for 3-4 minutes.
Stir in the sliced celery, carrots, and thyme; sauté for another 2 minutes.
Pour in the chicken broth, add the bay leaves and turmeric.
Return the chicken thighs to the pot, season with 3/4 teaspoon salt and 1/4 teaspoon black pepper.
Cover and simmer for 30 minutes, adjusting heat as needed.
Remove the bay leaves and chicken thighs with tongs and place chicken on a cutting board.
Stir the egg noodles into the soup and simmer for 6-9 minutes until noodles are cooked.
Remove the chicken skin and bones, shred the chicken, and stir it back into the soup.
In a small bowl, whisk together the cornstarch and lemon juice, then stir into the soup to thicken slightly.
Add the chopped parsley, taste, and adjust salt and pepper as needed.
Serve hot and enjoy your homemade comfort food.
