Preheat oven to 400 degrees.
Spoon very thick mashed potatoes (or cauliflower mashed “potatoes”) into a piping bag or into a ziplock bag, then cut the corner off. Pipe onto a buttered baking sheet in whatever shape you like. Bake until golden brown.
Even quicker – scoop potatoes with an ice-cream scoop onto buttered baking sheet and bake.
Before spooning into the piping bag stir one of the following into the mashed potatoes:
- dairy or dairy-free Parmesan cheese before baking
- any pureed vegetable such as broccoli, cauliflower, celery, spinach …
- chopped vegetables
- veggie bacon bits
