Turn Leftover Mashed Potatoes into Crispy Mashed Potato Fries
I love this mashed potato fries recipe because it turns simple mashed potatoes into crispy mashed potato fries that feel like a real treat. The bit of cornstarch makes these mashed potato fries with cornstarch extra crisp, while the soft, garlicky center keeps them comforting. My family loves the golden crunch outside and the smooth mashed potato interior. These mashed potato French fries are pure comfort food fun, easy to make from scratch or with leftover mashed potatoes.
This mashed potato fries recipe is always a hit, golden, crunchy, and full of flavor. I love serving them with cane's sauce and watching how quickly they disappear. These crispy potato sticks are tender inside, crisp outside, and a delicious way to use up boiled potato leftovers.

🧾Ingredients
You'll find the exact measurements in the recipe card, but here's a closer look at a few of the ingredients and why I use them.
- Potatoes: I like using them as the base because they create a creamy interior that makes the fries special.
- Garlic & Butter: Cooking garlic gently in butter gives a warm, rich flavor that melts perfectly into the dough.
- Flour & Cornstarch: I mix the two to keep the fries light while still holding their shape when fried.
- Spring Onions: I love stirring these in at the end for a fresh pop of color and mild onion bite.

1. Boil & Mash Potatoes: Peel, chop, and boil potatoes until tender (about 20 minutes). Drain and mash until smooth.
2. Cook Base Mixture: Sauté garlic in butter, then add water, salt, pepper, and flour. Cook until thick and dough-like.

🍽 What to Serve with Mashed Potato Fries
These fries go well with just about anything; pair them with roasted chicken, grilled meats, or even a fresh tomato salad. I also love serving them with a simple dipping sauce like pepper mayonnaise or ketchup for snacking.
💭My Tips for Recipe Success
Keep the Oil Hot: I've found that maintaining medium-high heat keeps the fries crisp without making them greasy.
Cut Evenly: I always take a moment to keep the sticks roughly the same size; it helps them fry evenly and look neat when served.
Reheat in the Oven: If you have leftovers, I always pop mashed potato fries into a hot oven for a few minutes to bring the crunch back.

Recipe
Mashed Potato Fries
Ingredients
- 450 g Russel Potatoes - Peeled, cut, and boiled until fork tender
- 9 Cloves Garlic - Minced
- 20 g Unsalted Butter
- 100 ml Water
- 1 teaspoon Salt
- ½ teaspoon Black Pepper - Freshly ground
- 40 g Flour
- 80 g Cornstarch
- 40 g Spring Onions - Chopped
Instructions
- Peel the potatoes and cut them into even pieces. Add them to a pot of water and boil for about 20 minutes, or until fork-tender. Drain well, then transfer to a large bowl and mash until smooth. Set aside.
- In a medium pan, melt the butter over low to medium heat. Add the minced garlic and cook for about 1 minute, just until fragrant. Pour in the water, season with salt and black pepper, and stir well to combine the flavors.
- Stir in the flour and cook for about 2 minutes, mixing constantly until it forms a thick, dough-like paste. Add the mashed potatoes and stir until everything blends together smoothly, then turn off the heat. Mix in the cornstarch and chopped spring onions until fully incorporated.
- Transfer the mixture onto a wooden board and roll it out to about 1 cm (½ inch) thick. Trim the edges to form a neat 20 × 20 cm (7.9 × 7.9 inch) square. Cut the square in half, then slice into sticks about 1.5 cm (0.6 inch) wide. Gently roll each stick to smooth the sides and arrange them on a sheet of parchment paper.
- Heat the oil in a deep pan over medium-high heat. Fry the sticks in batches until they turn golden and crisp. Remove with a slotted spoon, drain on paper towels, and serve hot.
