Set Ninja Foodi to Sauté (high) setting and allow it to heat up.
Heat olive oil and butter (or margarine). Add onion and garlic, and cook for 1-2 minutes or until softened and fragrant.
2 tablespoon extra virgin olive oil, 1 tablespoon butter or margarine, 4 cloves garlic, 1 medium-sized onion
Add celery, carrots, red bell pepper, and potatoes, then mix well.
2-3 celery ribs, 2 large carrots, 5 medium-sized potatoes, 1 medium red bell pepper
Add the chicken thighs and top with most seasonings - red pepper flakes, dried parsley, Italian seasoning, salt, black pepper, and chicken bouillon - then stir to combine.
600g bone-in, skinless chicken thighs, 1 teaspoon red pepper flakes, ½ teaspoon dried parsley, 1 teaspoon Italian seasoning, 1 teaspoon salt, 2 chicken bouillon cubes , black pepper
Add bay leaves, thyme, and chicken stock, then stir. Let the chicken simmer for 10-15 minutes.
1 teaspoon dried thyme, 3-5 bay leaves, 5 cups chicken stock
Add the water and rice then stir to combine. Turn the valve of your Ninja Foodi lid (or Instant Pot, or electric pressure cooker -see notes) to the sealing position and set it to pressure cook on High for 2-3 minutes if you like the rice to have a bite, otherwise pressure cook for 4 minutes.
4 cups water, ¾ cup long-grain white rice - uncooked
While the chicken soup is cooking, whisk together the milk and starch (or tapioca or arrowroot flour) until smooth.
½ cup milk, 1 teaspoon cornstarch,tapioca flour, or arrowroot flour
Once the pressure cooking time is over, allow it to release pressure naturally for 5 minutes.
Turn the valve to the Venting setting to quickly release the remaining pressure.
Remove the chicken pieces, shred them, and then return them to the pot. Discard the bay leaves.
Add the milk-starch mixture to the soup and stir until well incorporated. Add water or broth if you prefer a lighter soup, and check for salt and pepper.
Ladle into bowls, garnish with some freshly chopped parsley, then serve.
