Start by chopping the onion into small, translucent pieces and slicing the carrots thinly. Mince the garlic cloves and set everything aside.
Place the chopped onion and minced garlic into the crockpot and set it on low. Let them cook gently for about 10-15 minutes until fragrant and softened, with the onion turning translucent.
Add the sliced carrots and any other leftover vegetables you have to the crockpot. Pour in the chicken broth, which will serve as the flavorful base of your soup.
Stir in the shredded rotisserie chicken, spreading it evenly throughout the broth. This adds richness and protein to your soup.
Cover the crockpot and let everything simmer on low for about 4 to 6 hours. This slow cook melds the flavors and tenderizes the vegetables and chicken.
Halfway through, check the soup and give it a gentle stir. If it’s thickening too much, add a splash more broth or water to keep it soupy and fragrant.
Once the vegetables are tender and the broth is flavorful, taste and adjust seasoning with salt, pepper, or fresh herbs. If you like, add greens or extra vegetables during the last 30 minutes.
Turn off the crockpot and let the soup rest for about 10 minutes, allowing the flavors to settle and the broth to thicken slightly.
Use a ladle to serve the hot, fragrant soup into bowls. Garnish with chopped fresh herbs for a bright, fresh finish.
Enjoy your comforting bowl of leftover magic—warm, nourishing, and perfect for cozy evenings.
