Step‑by‑Step Instructions for Crispy Mashed Potato Fries
Step 1: Prep Potatoes
Begin by peeling the potatoes and cutting them into even-sized cubes. In a large pot, bring salted water to a boil, then carefully add the potato cubes. Cook them for about 15 minutes or until fork-tender. You’ll know they are ready when a fork easily slides through the potatoes. Drain and set them aside to cool slightly.
Step 2: Mash
Once the potatoes have cooled, transfer them to a mixing bowl and mash until smooth, making sure there are no lumps remaining. Fold in salt, black pepper, Parmesan cheese, parsley, and potato starch, mixing thoroughly to incorporate. The consistency should be thick yet pliable, similar to soft dough. This mixture will be the base for your Crispy Mashed Potato Fries.
Step 3: Shape
Dust your work surface lightly with flour to prevent sticking, then divide the potato mixture into two equal portions. Roll each portion into a rectangular shape about ½ inch thick, ensuring even thickness for cooking. Use a sharp knife or pizza cutter to slice the rectangles into thin strips. These will be your fries, ready for frying until they are perfectly golden.
Step 4: Fry
In a deep fryer or heavy skillet, heat oil to approximately 350°F (175°C). Carefully drop the potato strips into the hot oil in small batches to avoid overcrowding, which can cool the oil. Fry for about 5 to 7 minutes, turning occasionally, until they are golden brown and crispy on all sides. Use a slotted spoon to transfer the fries to a wire rack to drain excess oil.
Step 5: Serve
Once your Crispy Mashed Potato Fries are drained and slightly cooled, serve them immediately while hot and crispy. You can further sprinkle them with more Parmesan cheese or fresh herbs if desired. Pair these fries with your favorite dipping sauces, like ketchup or ranch, for an irresistible snack everyone will love!

Expert Tips for Crispy Mashed Potato Fries
-
Avoid Overboiling: Ensure you don’t boil the potatoes too long; check for fork-tenderness to prevent them from becoming mushy.
-
Chill the Mixture: Chill the mashed potato mixture for about 30 minutes before shaping. This makes it easier to handle and helps maintain the form during frying.
-
Heat the Oil: Use a thermometer to monitor oil temperature. Adding fries to oil that’s too cool can result in soggy Crispy Mashed Potato Fries.
-
Batch Frying: Fry in small batches to keep the oil temperature high and achieve that perfect golden crunch without steam cooking the fries.
-
Herb Variations: Feel free to experiment with different herbs like thyme or rosemary to provide extra flavor dimensions to your Crispy Mashed Potato Fries.

Crispy Mashed Potato Fries Recipe FAQs
How do I select the best potatoes for mashed potato fries?
Absolutely! For the best results in your crispy mashed potato fries, I recommend using russet or Yukon gold potatoes. These varieties have the right starch content, giving you a fluffy interior while maintaining that desired crispy exterior. Look for firm potatoes free from dark spots or soft areas to ensure maximum flavor and texture.
How should I store leftover crispy mashed potato fries?
Very! Store leftover crispy mashed potato fries in an airtight container in the refrigerator for up to 3 days. Before serving again, simply reheat them in a preheated oven at 400°F (200°C) for about 10 minutes. This way, they’ll regain their crispy texture—just as delicious as the first time!
Can I freeze uncooked mashed potato fries?
Absolutely! For longer storage, you can freeze uncooked potato sticks. First, spread them out in a single layer on a baking sheet and freeze until solid. Then, transfer the frozen strips to a zip-top bag. They can be stored for up to 1 month. When you’re ready to enjoy them, fry them directly from the freezer without thawing for the best results.
What can I do if my mashed potato fries turn out soggy?
No worries! If your crispy mashed potato fries come out soggy, this could likely be due to excess moisture. To avoid this, ensure that the potatoes are entirely dry before mashing. Additionally, you can chill the mashed mixture for about 30 minutes before shaping and frying to give it more structure. If you’ve already cooked them, try reheating in a hot oven—the high heat will help restore some of that crispness.
Are crispy mashed potato fries suitable for people with dietary restrictions?
Very! These fries can be vegetarian-friendly and easily adapted for vegan diets. Simply swap the Parmesan cheese for nutritional yeast for an umami flavor without dairy. Always check for any allergies related to specific ingredients, especially if serving to guests, to ensure everyone can join in the deliciousness of these crispy mashed potato fries.
Can my pets share in the delight of crispy mashed potato fries?
It’s best to keep these fries away from pets. While potatoes themselves can be safe for dogs in moderation, the added oil, salt, and cheese can be harmful. If you want to treat your furry friends, consider giving them plain, cooked potato chunks without any seasoning instead!
