Cook the aromatics (optional): In a large soup pot, sauté the onion in a little olive oil for 3–4 minutes.
Add the garlic and cook for 30 seconds.
Build the soup: Pour in the chicken broth.
Add the ranch seasoning, onion powder, black pepper, and smoked paprika. Stir well.
Add the chicken: Add the frozen rotisserie chicken. Bring to a gentle simmer for about 10 minutes, until heated through.
Add the broccoli: Stir in the frozen broccoli. Simmer another 8–10 minutes until tender.
Make it creamy: Cut the cream cheese into cubes. Whisk it into the hot soup until smooth. Stir in the cheddar cheese until melted.
Taste and adjust: Add more pepper or a splash of hot sauce if you like a little heat.
Serve: Top with turkey bacon, green onions, or an extra sprinkle of cheddar.
