Place CHICKEN THIGHS in the Crockpot. Generously season their surface with SALT and PEPPER. Add POTATOES, CELERY, CARROTS, ONION, GARLIC, BAY LEAF, THYME, and CHICKEN BROTH.
Cover the cooker and cook on HIGH for 3-4 hours or LOW for 8 hours. *see recipe footnote
Check the chicken for doneness by inserting a meat thermometer into the thickest part. It should read 165°F.
Transfer chicken thighs to a plate and shred with two forks. Stir the shredded chicken back into the soup. Add the PEAS and continue heating until warmed through.
Remove the bay leaf. Add more SALT and PEPPER, to taste. Serve warm, garnished with chopped PARSLEY.
To store, cool the soup completely. Refrigerate in an airtight container up to 5 days or freeze up to 3 months (or longer if vacuum sealed). Thaw overnight in the refrigerator.

Notes
If using rotisserie chicken: I recommend adding it near the end of the cook cycle to ensure that it stays moist and tender.Cut vegetables evenly: When dicing your potatoes, carrots, and celery, cut them into consistent-sized pieces to ensure even cooking.No need for precooking: Save time by skipping the stove. Everything goes straight into the crockpot.Frozen peas: If you're using frozen peas, there's no need to thaw them. Add them in during the last 30 minutes to prevent them from getting too soft.Slow cooker timing: Crockpot models may vary, so your soup may cook faster or slower than the stated recipe time. Adjust accordingly.Adjust the salt before serving: This soup has very simple seasonings, so it's crucial to add more salt to taste once it is fully cooked.STOVE INSTRUCTIONS: Season the chicken thighs with salt and pepper and add them to a large soup pot. Add the potatoes, celery, carrots, onion, garlic, bay leaf, thyme, and chicken broth. Bring to a boil, then reduce to a simmer, cover, and cook 25–30 minutes, until the chicken is cooked through and the vegetables are tender. Remove the chicken, shred, and return it to the pot. Add the peas and simmer 5 minutes, just until heated through.
