Season chicken with salt, pepper, and Italian seasoning. Heat olive oil in soup pot over medium-high heat. Add chicken and cook for 3 to 4 minutes per side until browned. Remove and set aside.
Let chicken rest for 10 minutes, then shred into bite-sized pieces, discarding bones.
Melt butter in the same pot over medium heat, scraping up browned bits from the bottom.
Add diced onions, carrots, and celery. Cook for 5 minutes until softened.
Add minced garlic, Worcestershire sauce, hot sauce, and all dried herbs and spices. Cook for 1 more minute until fragrant.
Add chicken broth and shredded chicken. Bring to gentle bubble, then reduce to simmer. Cover partially and simmer for 15 minutes.
Add refrigerated tortellini and simmer uncovered for about 3 minutes until tortellini floats and is tender.
Taste and adjust seasoning with salt and pepper. Serve hot.
Notes
Bone-in chicken adds most flavor but boneless chicken or rotisserie chicken works. Rotisserie chicken reduces cook time.
Use RANA refrigerated cheese-filled tortellini for best results.
Hot sauce, Worcestershire sauce, and mustard powder enhance flavor without making soup spicy.
Add parmesan rind when adding broth for extra depth.
Frozen peas, corn, or green beans can be added 10 minutes before serving.
Store in airtight container in refrigerator for up to 3 days. Store tortellini separately to prevent over-absorption.
Soup base freezes well for up to 3 months. Cook tortellini fresh when serving if freezing.
