Ingredients

• Leftover French fries (any cut or brand)

• Optional:

  • Spray oil (for extra crispiness)

  • Salt, garlic powder, or parmesan for finishing

  • Dipping sauces for serving

Instructions

Step 1: Preheat the Air Fryer

Set air fryer to 375°F (190°C) and preheat for 2–3 minutes.

Step 2: Spread the Fries

Arrange fries in a single layer in the air fryer basket. Avoid stacking so they reheat evenly and get crispy.

Step 3: Reheat to Perfection

• Air fry at 375°F for 4–6 minutes, shaking halfway through

• Thin fries (shoestring or fast food style) may take just 3–4 minutes

• Thick-cut or loaded fries may need 6–7 minutes

• Check for hot centers and crisp edges

Step 4: Season & Serve

Toss with a pinch of salt or any finishing seasoning. Serve hot with dips or main dishes.

Helps restore crunch, especially for thicker fries or older leftovers.

Shake the Basket Halfway Through

Perforated parchment keeps your air fryer tidy, especially if reheating cheesy or saucy fries.
