Step‑by‑Step Instructions for Crispy Mashed Potato Fries
Step 1: Prepare the Potatoes
Peel and cube 2-3 medium-sized potatoes before placing them in a pot of salted water. Bring the water to a boil over medium-high heat, then cook the potatoes for about 15-20 minutes, or until fork-tender. Drain the potatoes in a colander and let them sit for a few minutes to remove excess moisture before mashing.
Step 2: Mash and Mix
In a mixing bowl, mash the cooked potatoes until they are smooth and creamy. Stir in ½ cup of grated Parmesan cheese, a sprinkle of black pepper, and a handful of fresh parsley. To build a crispy outer layer, add in ¼ cup of potato starch and mix until everything is well combined, creating a uniform mixture for your Crispy Mashed Potato Fries.
Step 3: Shape the Fries
Divide the potato mixture into portions and roll each portion into ½-inch thick rectangles. Use a sharp knife to cut them into strips, resembling traditional fries. If the mixture feels sticky, consider chilling it in the refrigerator for about 15 minutes to make it easier to handle and shape.
Step 4: Heat the Oil
In a deep, heavy-bottomed pan, pour in enough oil for frying—about 2-3 inches deep—then heat it over medium-high heat until it reaches 350°F (175°C). To test if the oil is ready, drop a small piece of the potato mixture into the oil; it should sizzle immediately if it’s properly heated.
Step 5: Fry the Strips
Carefully add the potato strips to the hot oil in small batches, ensuring not to overcrowd the pan. Fry the strips for about 5-7 minutes, turning occasionally, until they are golden brown and crispy on all sides. Once done, use a slotted spoon to remove the fries from the oil and let them drain on a wire rack.
Step 6: Serve and Enjoy
Once the Crispy Mashed Potato Fries have drained, serve them hot, either plain or garnished with additional grated Parmesan cheese and fresh parsley for a pop of flavor. Pair with your favorite dipping sauces like ketchup, ranch dressing, or garlic sauce, and enjoy this delightful twist on traditional fries!

Expert Tips for Crispy Mashed Potato Fries
-
Choose the Right Potatoes: Starchy potatoes like Russets yield the best texture, while waxy types can result in a gummy fry.
-
Avoid Overcooking: Boil potatoes until fork-tender but not too soft; overcooked potatoes will lead to mushy fries.
-
Chill for Easy Handling: For better shaping, chill the mashed potato mixture in the fridge before forming into strips to decrease stickiness.
-
Maintain Oil Temperature: Fry in small batches to keep the oil hot; this ensures crispiness and even cooking for your crispy mashed potato fries.
-
Use a Wire Rack: After frying, let the fries cool on a wire rack rather than paper towels to prevent moisture and retain that desirable crunch.
How to Store and Freeze Crispy Mashed Potato Fries
Fridge: Store leftover crispy mashed potato fries in an airtight container for up to 3 days to keep them fresh and flavorful.
Freezer: For longer storage, freeze uncooked potato strips by laying them out on a baking sheet until firm, then transfer to a freezer bag for up to 1 month.
Reheating: To reheat fries, bake them at 400°F (200°C) for about 10-15 minutes until crispy again. This ensures they maintain their delicious texture after storage.
Tip: Enjoying these crispy mashed potato fries fresh is best, but with proper storage and reheating, they’re still a delightful treat!

Crispy Mashed Potato Fries Recipe FAQs
What kind of potatoes should I use for crispy mashed potato fries?
Absolutely! For the best results, I recommend using starchy potatoes like Russets or Yukon Golds. They create a fluffy interior that pairs perfectly with the crispy exterior. If you’re feeling adventurous, you can substitute sweet potatoes for a sweeter, healthier twist!
How long can I store crispy mashed potato fries in the fridge?
You can store leftover crispy mashed potato fries in an airtight container in the refrigerator for up to 3 days. To keep them as fresh as possible, it’s best to reheat them in the oven rather than the microwave, as this helps regain some of that delightful crispiness.
Can I freeze uncooked mashed potato fries?
Very much! To freeze uncooked fries, first lay them out in a single layer on a baking sheet and place them in the freezer until firm, about 1-2 hours. Then transfer the fries to a zip-top bag and keep them frozen for up to 1 month. This method helps prevent them from sticking together!
What should I do if my mashed potato fries aren’t crisping up when frying?
If your crispy mashed potato fries aren’t getting that golden, crispy exterior, it could be a few things. First, ensure your oil is hot enough (350°F or 175°C) before frying. Fry in small batches to keep the temperature consistent. If you’ve followed these steps and they’re still not crisping, try adding a bit more potato starch to the mixture, as this helps achieve that perfect crunch!
Can pets have any of the ingredients in crispy mashed potato fries?
Moderation is key! While potatoes themselves are safe for most dogs, avoid giving them fries with added salt, cheese, or spices. Plain mashed potatoes can be a treat, but it’s best to skip the melting cheese and seasonings for your furry friends. Always consult your vet if you’re unsure about new foods for your pets.
How can I make my fries healthier?
If you’re looking for a healthier option, try baking or air-frying the crispy mashed potato fries instead of deep frying. Simply preheat your oven to 425°F (220°C), arrange the fries in a single layer on a baking sheet, and bake for about 20-25 minutes, flipping halfway through. This method uses far less oil while still delivering a satisfyingly crispy texture!
