Add the garlic cloves and sauté for about a minute until fragrant.
Transfer the chicken mixture to your slow cooker. Add the carrots, celery, broth, lemon, ground coriander, and fresh dill to the pot. Stir to combine.
Cook on high for 3-4 hours or on low for 6-8 hours until the veggies are soft.
About 10 minutes before serving, cook your rotini pasta according to the package directions.

Serve with extra dill sprinkled on top and lemon wedges on the side if desired, and enjoy!
