Add the turkey, veggies, seasonings, and broth to the slow cooker (WAIT TO ADD THE CORNSTARCH, WATER AND HEAVY CREAM).
Stir.
Place the lid on the slow cooker. Cook for 4 hours on HIGH or 8 hours on LOW.
When the cooking time is up, whisk together the cold water and corn starch, stir into the chowder. Stir in the heavy cream.
Cook on HIGH for 30 minutes longer or until soup thickens.
Serve and enjoy!
Stovetop Method
Add the turkey, veggies, seasonings, and broth to a large pot and bring it to a gentle simmer. Let everything cook until the potatoes and carrots are nice and tender. Stir in the cornstarch slurry and heavy cream, simmer a few more minutes until it thickens, and you’re good to go. You may need to add a little extra broth if it cooks down too much.
