Prep the Ingredients. Start by peeling and chopping the potatoes and carrots into bite-sized pieces. Dice the celery and onion, and mince the garlic. If you’re using raw turkey, cut it into chunks.
Layer the Ingredients. Add the turkey, potatoes, carrots, celery, onion, and garlic to the slow cooker. Sprinkle in the fresh thyme and add the bay leaves. Pour in the chicken broth.
Season and Cook. Add salt and pepper to taste. Cover and cook on low for 6-8 hours or on high for 3-4 hours, until the vegetables are tender and the turkey is fully cooked or heated through.
Thicken the Stew (Optional). If you prefer a thicker stew, mix cornstarch with a bit of water to create a slurry. Stir it into the stew in the last 30 minutes of cooking and let it thicken.
Serve and Enjoy. Remove the bay leaves and serve hot, garnished with fresh parsley or thyme.
