I melt butter in a large pot. I add onion, carrots, and celery. I cook them until soft. The kitchen already smells amazing. You will notice the veggies turn tender and glossy.

I stir in garlic and cook for a few seconds. Then I pour in chicken broth. I bring everything to a gentle boil. This builds the base flavor of the soup.

I add the rice to the pot. I lower the heat and let it simmer. I stir occasionally so the rice cooks evenly and does not stick.

I add shredded chicken, salt, pepper, and thyme. I simmer the soup until the rice is soft and the chicken is heated through.

I taste the soup and adjust the seasoning. Once done, I turn off the heat. Your soup is ready to serve warm.
