Ingredients:
- 3 large Russet or Baking Potatoes (approx. 680 g)
- Cold Water, as needed (for soaking)
- 2 Tbsp Extra Virgin Olive Oil or Neutral Oil (30 ml)
- 1 tsp Fine Sea Salt, or to taste (5 g)
- 1/2 tsp Freshly Ground Black Pepper (Optional)
Instructions:
- Preheat oven to 375°F (190°C). Line two large baking sheets with parchment paper or silicone mats.
- Wash the potatoes thoroughly. Using a mandoline, slice the potatoes into razor-thin rounds (aim for 1.5 mm thickness). Uniformity is vital for crispness.
- Immediately place the slices into a large bowl filled with cold water. Swish gently until the water turns cloudy with starch. Drain, refill, and repeat 2-3 times until the water runs mostly clear.
- Drain the potatoes one last time. Spread the wet slices in a single layer over clean kitchen towels. Layer another towel on top and press firmly to wick away as much moisture as possible. This meticulous drying step is critical.
- Transfer the very dry potato slices to a clean, dry bowl. Drizzle with the 2 Tbsp of oil and toss gently until every slice is just coated. Season generously with salt and pepper.
- Arrange the potato slices on the prepared baking sheets in a single layer. They must not overlap.
- Place the sheets into the preheated oven. Bake for 10 minutes.
- After 10 minutes, use tongs to carefully flip each chip (or toss the pan). Reduce the oven temperature slightly to 350°F (175°C) and continue baking for another 15-20 minutes.
- Monitor the chips closely. Remove the chips that are golden brown and firm (due to natural variations, some will cook faster) and place them on a wire rack.
- Allow the baked chips to cool completely (5-10 minutes). They will firm up and become shatteringly crisp as they cool before serving.
