There's something magical about transforming yesterday's rotisserie chicken into a soul-warming soup that tastes like it's been simmering for hours. This recipe has become my go-to solution for those busy weeks when I need to stretch a rotisserie chicken into an extra meal. The combination of tender vegetables, rich broth, and chunks of flavorful chicken creates a soup that's far more than just leftovers.
After countless iterations, I've found that the secret lies in building layers of flavor, starting with those precious bits left on the rotisserie chicken bones.
Essential Ingredients and Selection Tips
- Rotisserie Chicken: Save every bit - meat, skin, and bones
- Yellow Onions: Choose firm onions with tight, papery skin
- Celery: Select bright, crisp stalks with fresh leaves
- Carrots: Look for firm, bright orange carrots without cracks
- Fresh Mushrooms: Choose closed caps for best flavor
- Heavy Cream: Full-fat adds silky richness
- Fresh Herbs: Add brightness and visual appeal

Detailed Preparation Steps
- Building Your Broth Base:
- Remove meat from bones carefully. Save skin and bones for stock. Chop meat into bite-sized pieces. Store meat covered in refrigerator. Place bones in slow cooker with aromatics.
- Creating the Perfect Stock:
- Cover bones with cold water. Add onion ends and celery leaves. Include a bay leaf and peppercorns. Keep temperature low and steady. Strain through fine-mesh sieve. Let cool before removing fat.
- Vegetable Preparation:
- Dice onions uniformly for even cooking. Slice celery on diagonal for visual appeal. Cut carrots into coins or half-moons. Clean mushrooms with damp paper towel. Keep pieces similar size for even cooking.
- Building the Soup Base:
- Heat oil until shimmering but not smoking. Sauté onions until translucent. Add celery and cook until softened. Incorporate mushrooms in batches. Create roux with flour for thickening.
- Final Assembly:
- Add broth gradually while stirring. Introduce carrots at right time. Simmer until vegetables are tender. Add chicken just until heated. Finish with cream off heat.
