For the Fries:

4 large russet potatoes, cut into matchsticks
2 tablespoons olive oil
2 teaspoons garlic powder
½ teaspoon smoked paprika
Salt and pepper to taste
¼ cup grated Parmesan cheese
1 tablespoon truffle oil (white or black, depending on preference)
Fresh parsley, chopped (optional for garnish)

For the Cheese Sauce:

2 tablespoons butter
2 tablespoons all-purpose flour
1 cup whole milk
1 cup sharp cheddar cheese, shredded
¼ teaspoon garlic powder
Salt and pepper to taste

Optional add-ins: pinch of cayenne, splash of cream for richness, or a mix of cheeses like Monterey Jack and Gruyère for a more complex flavor.

Step-by-Step Instructions

Total Time: ~45 minutes

️ Serves: 4–6

Step 1: Prep the Potatoes

Wash, peel (optional), and cut russet potatoes into ¼-inch fries.
Soak them in cold water for 30 minutes to remove excess starch—this helps them become extra crispy.
Drain and pat dry thoroughly with paper towels.

Step 2: Bake or Fry the Fries

Oven-Baked Version:

Preheat oven to 425°F (220°C).
Toss dried fries with olive oil, garlic powder, paprika, salt, and pepper.
Spread in a single layer on a parchment-lined baking sheet.
Bake for 30–35 minutes, flipping halfway, until golden and crispy.

Air Fryer Version:

Preheat air fryer to 375°F (190°C).
Cook fries in batches for 18–20 minutes, shaking occasionally.

Deep-Fried Version:

Heat oil in a deep pot to 350°F (175°C).
Fry in batches for 3–4 minutes or until golden. Drain on paper towels.

Step 3: Make the Cheese Sauce

In a medium saucepan, melt butter over medium heat.
Whisk in flour to form a roux. Cook for 1 minute until slightly golden.
Gradually whisk in milk, stirring constantly until thickened.
Stir in shredded cheese, garlic powder, and season to taste.
Keep warm on low heat until ready to serve.

Step 4: Finish and Assemble

Once the fries are crispy, toss them with truffle oil and grated Parmesan.
Plate the fries, drizzle with cheese sauce, and garnish with fresh parsley or additional Parmesan.

Expert Tips for Perfect Results

Soak and dry: Always soak potatoes and dry them completely for maximum crispness.
Don’t overcrowd the baking sheet or fryer.
Use high-quality truffle oil; a little goes a long way.
Serve immediately—the cheese sauce thickens as it cools.
