Ingredients You Need
- Purple potatoes: You'll use one pound. Rinse and scrub them before roasting.
- Olive oil: Use this or another neutral oil.

- Parmesan cheese: You can use shredded or grated cheese.
- Garlic: Mince fresh garlic.
- Butter: Melt it.
Instructions to make Garlic Parmesan Roasted Purple Potatoes:
Slice and Season
Preheat the oven to 375°. Spray a 9x13 baking dish with nonstick cooking spray.
Cut your potatoes in half lengthwise then place them in a large bowl. Drizzle the olive oil over the potatoes. Add all of the seasonings including the seasoned salt, garlic powder, onion powder, and black pepper.
Stir the potatoes around with the seasonings and olive oil until they are all evenly coated.
Add Parmesan and Garlic
Add the parmesan cheese and minced garlic into a separate bowl, and pour the melted butter over it. Then mix it up with a spoon until it forms a thick paste-like consistency.
Roast
Place the baking dish in the oven and roast the potatoes for 30 minutes. The cheese should be golden brown and slightly hardened.
Use a spatula to remove the potatoes from the dish, ensuring to get it under the cheese so it is coating the potato. Serve immediately and enjoy!
Pro-Tips:
- Cut the potatoes uniformly so they roast evenly.
- The skin of purple potatoes is thin, like red potatoes, so there is no need to peel them.
- Potatoes are naturally gluten-free, making them a great base for a gluten-free side.
What are Purple Potatoes?
Purple potatoes are fingerling potatoes that originated in the Andes mountains of South America. There are many types including All Blue, Michigan Blue, Purple Sweet Potatoes, Purple Eyes, Purple Peruvian, Adirondack Blue, and the Purple Majesty potato.
All Blue are one of the more popular varieties that you're likely to find in the grocery store.
Why are purple potatoes purple?
They range in color from a deep blue-purple hue to a brilliant violet. Their distinct vibrant color comes from a natural pigment known as anthocyanin. Anthocyanins are also an antioxidant.
Spread the parmesan garlic mixture into the bottom of the baking dish in one even layer. Firmly press the flat side of the potatoes into the cheese mixture in the dish.
Storing and Reheating:
Store leftover potatoes in an airtight container in the fridge for up to 5 days. To freeze, store them in a freezer-safe bag for up to 3 months. When you're ready to enjoy them, reheat them in the oven. There's no need to thaw them.
FAQ:
Are purple potatoes healthier than white?
Yes! Purple potatoes have more antioxidants than white and yellow potatoes. And baking them instead of frying them makes them a healthier choice too. The glycemic index is lower than other potatoes so they are better for your blood sugar levels.
Do purple potatoes taste different than regular potatoes?
They taste similar to Russet potatoes but they're moister with less starch. Purple potatoes are denser with a nutty, earthier flavor than most white potatoes. They are slightly sweet but not nearly as much as sweet potatoes.
When are purple potatoes in season?
You can find them throughout the year but they harvest in the fall. Most farmer's markets carry them throughout the year too.
How do you eat purple potatoes?
Aside from roasting, they can be used just like any other potatoes to make mashed potatoes, potato salad, and even French fries.

Yes it is dried parsley. It is optional, but great for a little Razzle Dazzle 😉
