Add shredded turkey, pumpkin puree, chopped onion, minced garlic, chicken broth, cinnamon, thyme, black pepper, and a pinch of salt into your slow cooker. Stir everything together until well combined, ensuring the spices and pumpkin are evenly distributed.
Cover the slow cooker with its lid and cook on low for 6 hours, allowing the flavors to meld and the broth to thicken slightly. The stew will start to fragrant fill your kitchen with warming spices and pumpkin aroma during this time.
After cooking, open the lid and give the stew a gentle stir. The mixture should be velvety and thickened, with the pumpkin and turkey integrating seamlessly into the broth. Adjust seasoning with additional salt if needed.
For a smoother, silkier texture, you can ladle the stew into a blender and blend until smooth, or use an immersion blender directly in the slow cooker—this step is optional, depending on your preference.
Once the stew reaches your desired creaminess, serve it hot in bowls. Garnish with a sprinkle of thyme or a dash of cinnamon if you like, and enjoy the cozy, velvety soup that’s perfect for fall evenings.
