Roasted Crispy Polenta Potatoes With Garlic and Rosemary

Crispy Polenta Potatoes Pin 3

These roasted crispy polenta potatoes are so incredibly delicious, they’re practically addicting. They do use a fair amount of oil, so I try to save these for special occasions. They’re absolutely perfect as a holiday side dish or for anytime you want to take your roasted potatoes to the next level. The smashed garlic cloves roast with the potatoes and make the very best bites – if you love garlic, I’d definitely think about adding way more cloves!

Recipe Notes

*I used Pamela’s gluten free flour blend. If you don’t want to use a store bought blend, the homemade mixture I would use is: 1 Tablespoon white rice flour, 1/2 Tablespoon potato starch, and 1/2 Tablespoon tapioca starch.
