What are Fingerling Potatoes?
Fingerling potatoes are small “finger-shaped” potatoes that are sometimes mistaken for new potatoes. They are perfect for roasting because their skin is super thin, so there is no need to peel them. You can substitute fingerling potatoes for any roasted potato side dish recipe that you find.
New Potatoes Vs. Fingerling Potatoes
Both new potatoes and fingerling potatoes are tiny, have thin skin, and are great for roasting but there are some big differences. First of all, new potatoes aren’t actually a variety at all. They are simply immature potatoes that have been picked from the fields before they are fully grown.
Another major difference is that because new potatoes are not fully matured, their skin is far more delicate therefore limiting the shelf life. By comparison, fingerling potatoes have a much longer shelf life.
While we prefer fingerling potatoes, new potatoes make an excellent substitute and can often be easier to find at the grocery store.
Ingredients in Rosemary and Parmesan Fingerling Potatoes
- Fingerling Potatoes - find potatoes that are firm and roughly the same size. You can also substitute new potatoes or Yukon golds.
- Avocado Oil - we love using avocado oil for roasting veggies, but you can also substitute olive oil if you prefer.
- Seasoning - this recipe calls for seasoning with garlic powder, onion powder, Italian seasoning, salt and pepper. You can always feel free to adjust quantities and add or remove spices as desired.
- Fresh Rosemary - if you don’t have, or can’t find, fresh rosemary you can either skip or substitute with fresh thyme.
- Parmesan Cheese - freshly grated tastes and melts best.
How to Make Rosemary and Parmesan Fingerling Potatoes
- Prep potatoes. Place potatoes in a large bowl, or a ziplock bag, and drizzle them with 3 tablespoons of avocado oil. Toss the potatoes until evenly coated, then add the fresh rosemary, garlic powder, onion powder, Italian Seasoning, Parmesan cheese, salt and pepper. Toss again until the potatoes are evenly coated.
- Place potatoes onto a baking sheet. Grease a large baking sheet with another 3 tablespoons of avocado oil, spreading it evenly. Remove potatoes from the bowl or ziplock bag onto the prepared baking sheet, squeezing out as much of the seasoning from the inside of the bag as possible. Spread out the potatoes in a single layer on the baking sheet.
- Roast. Bake fingerling potatoes in oven, preheated to 425 degrees, for about 20 minutes, or until the edges of the potatoes begin to brown. Using a spatula, turn the potatoes and cook for another 15-20 minutes so the other side can brown.
- Serve. Once the potatoes are golden brown, remove from the oven and season with additional salt and pepper to taste. Serve immediately and enjoy!
Tips for Cooking Fingerling Potatoes
- Be sure to rinse the potatoes before cooking, and rub them between your fingers to be sure the dirt has been removed.
- There is no need to peel fingerling potatoes because their skin is so thin and soft.
- Some more delicious seasoning ideas include fresh herbs (thyme, oregano, dill), minced fresh garlic, cumin and paprika. Freshly squeezed lemon juice tastes great, too.
- You can also cook fingerling potatoes in a cast-iron skillet, or non-stick skillet. It’s a little quicker, but you do need to be close-by while cooking them. Add a few tablespoons of avocado or olive oil to the bottom of the skillet and cook over medium heat to crisp them up, just like you would with hash browns. Season about halfway through the cooking, then finish with grated Parmesan and a squeeze of lemon juice.
- To boil fingerling potatoes, add to boiling water and cook for 20-30 minutes, depending on the size. To test it they are done, poke a fork into one and it shouldn’t stick.
Frequently Asked Questions
What are the best potatoes for roasting?
Honestly, we haven’t found a potato that won’t work in this recipe. You can use large Russet potatoes, red potatoes, tri-color potatoes, small potatoes or even a mix of them. Just be sure they are all cut into roughly the same size pieces.
Why aren’t my Rosemary and Parmesan Potatoes crispy?
Most likely, your oven wasn’t hot enough. We like to roast them at 425 degrees because it’s hot enough to make sure they don’t completely dry out, but not so how that they completely burn on the outside.
How Long should I roast potatoes?
Cook times will always vary depending on how hot the oven is, how much you are cooking at once, how large the pieces are, how often you open the oven door and even your individual oven.
This recipe calls for cutting your potatoes in half and setting the oven at 425 degrees, which typically takes between 30-40 minutes total to roast.
How long do leftover roasted potatoes last?
Roasted potatoes will always taste best if eaten shortly after roasting. If you do have leftovers, cool them completely and store in the fridge in an airtight container. They can be added to salads, soups, breakfast scrambles, and more.
