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!

Make Ahead Options
These Crispy Mashed Potato Fries are an excellent meal prep option for those busy weeknights! You can prepare the mashed potato mixture up to 24 hours in advance. Simply mash the potatoes, incorporate the Parmesan cheese, black pepper, parsley, and potato starch, then chill the mixture in an airtight container. This helps maintain the flavor and texture, preventing browning. When you’re ready to cook, shape the fries and fry them directly from the refrigerator. For longer storage, you could freeze the formed fries and cook them directly from frozen, ensuring you have a quick, delicious snack ready whenever the craving strikes!

Expert Tips for Crispy Mashed Potato Fries
