Let frozen shredded potatoes slightly thaw then mix everything together in a large bowl.
Once thawed, coat the waffle maker with non-stick cooking spray.
Working in batches, evenly distribute the shredded potato mixture on the preheated waffle maker. I typically use a little less than 1 cup per batch.
Close the waffle maker completely and cook until browned and crispy, about 10-15 minutes.
Enjoy immediately or let cool on a wire rack until ready to eat or store.
Notes
Cooking time and serving size may vary depending on the type of waffle maker you have. It's okay to give your hash brown waffles a peek to ensure they're getting cooked through and perfectly golden brown.Store in an airtight bag or container in the refrigerator for up to 1 week or freezer for up to 3 months.Reheat in a toaster oven or standard toaster until warm and crispy.
