Heat olive oil in a large pot over medium heat.
Add diced onion, carrots, and celery, sautéing until the onion is translucent and fragrant.
Stir in the minced garlic and cubed chicken breast, cooking until the chicken is lightly browned on all sides.
Add the cubed sweet potatoes, sea salt, black pepper, and dried thyme, stirring to coat the vegetables.
Pour in the chicken broth and bring the mixture to a gentle boil.
Reduce heat to low, cover, and simmer for 20 minutes or until the sweet potatoes are tender and the chicken is cooked through.
Serve warm in a bowl, ensuring a balance of chicken and vegetables in every scoop.
