Heat olive oil in a large pot or Dutch oven over medium heat. Add chicken and cook until browned and cooked through. Remove chicken from pot and set aside.
1 tablespoon olive oil, 1.5 pounds boneless, skinless chicken breasts
Add onion, carrots, and celery to the pot and cook until softened, about 5-7 minutes. Stir in the frozen peas and corn.
1 cup chopped onion, 1 cup chopped carrots, 1 cup chopped celery, 1 cup frozen peas, 1 cup frozen corn
Add the orzo to the pot and pour in the chicken broth. Bring to a boil, then reduce heat, cover, and simmer for 10-12 minutes, or until the orzo is tender and the liquid is mostly absorbed.
1 cup orzo pasta, 4 cups chicken broth
While the orzo is cooking, melt butter in a saucepan over medium heat. Whisk in the flour and cook for 1 minute. Gradually whisk in the milk and heavy cream until smooth. Bring to a simmer, stirring constantly.
1/4 cup butter, 1/4 cup all-purpose flour, 1 cup milk, 1/2 cup heavy cream
Stir in the salt, pepper, thyme, and garlic powder. Cook for 2-3 minutes, or until the sauce has thickened.
1/2 teaspoon salt, 1/4 teaspoon black pepper, 1/4 teaspoon dried thyme, 1/4 teaspoon garlic powder
Stir the cooked chicken and creamy sauce into the orzo and vegetable mixture. Mix until well combined.
