Heat olive oil in a large pot over medium heat. Add chopped onion and cook for 4-5 minutes until softened. Add minced garlic and cook for 1 minute until fragrant.
Pour in chicken broth and bring to a simmer.
Add egg noodles and cook for 6-8 minutes until al dente, stirring occasionally.
Reduce heat to low. Add shredded chicken, cubed cream cheese, shredded cheddar cheese, bacon bits, and ranch seasoning mix.
Stir continuously for 3-4 minutes until cheeses are fully melted and soup is smooth and creamy.
Season with salt and pepper to taste. Simmer gently for 2-3 minutes to meld flavors.
Ladle into bowls and garnish with fresh chopped chives. Serve hot.
Notes
Don’t boil soup after adding cream cheese to prevent separation. Keep heat on low and stir constantly.
Rotisserie chicken saves time and adds great flavor. For best texture, shred rather than dice the chicken.
Soup thickens as it cools. Add chicken broth when reheating to restore creamy consistency.
