In a large mixing bowl, add ground turkey, rice, eggs, Italian seasoning, salt and pepper. Using your hands, mix just enough to combine.
Form 10 large meatballs a size just a bit shy of a tennis ball’s size. Or you can make 20 or so smaller meatballs.
Place in a single layer on a bottom of large slow cooker. Meatballs will fit snuggly. Just pack them gently and tight. Pour broth gently over the meatballs.
Slow cook on Low for 7-8 hours or on High for 3-4 hours.
In a small bowl, whisk cold water with cornstarch. Pour slurry over the meatballs, cover and cook on High for 10-20 minutes or until sauce has thickened. Serve warm.
Notes
Store:Refrigerate leftovers in an airtight container for up to 5 days.
Freeze: Fully cook, cool completely, and freeze in an airtight container for up to 3 months. Thaw in a refrigerator overnight. Reheat in a microwave or in the oven at 375 F for 10 minutes.
In Instant Pot: Pressure cook on High pressure for 15 minutes in 8 quart Instant Pot or for 20 minutes in 6 quart Instant Pot. Release pressure right away and separate meatballs. Press Saute, whisk in a slurry and cook until sauce has thickened a bit.
In the oven: Bake porcupine meatballs in a baking dish while covered in preheated oven to 375 degrees F oven for 45 minutes. Check for doneness and if rice is ready, uncover and pour the slurry into the liquid spots. Bake for another 5 minutes or until sauce has thickened.
