How to Make Oven Baked Potato Slices
Step 1: Prepare the Potatoes
Slice 2 medium Russet potatoes into ¼-inch thick rounds using a sharp knife or mandoline.
Step 2: Prepare the Ice Bath
Soak the slices in cold water for 30 minutes to remove excess starch. This helps them crisp up in the oven instead of becoming soggy.
Step 3: Season the Potatoes
Drain and pat dry the potatoes with a towel. Toss them with 1 tablespoon olive oil, ½ teaspoon garlic powder, salt, and pepper.
Arrange them in a single layer on a parchment-lined baking sheet (no overlapping for even crisping).
📌 Pro Tip: Spray parchment paper lightly with olive oil so potatoes won't stick.
Step 4: Bake the Potatoes
Bake at 425°F (220°C) for 25-30 minutes, flipping halfway through. The edges should turn golden brown and crispy.
Remove the potatoes from the oven and top each slice with a mix of 1 cup shredded cheese and ⅓ cup crumbled bacon. Return to the oven and bake for 5-7 minutes until the cheese is fully melted. Add chopped green onions and serve immediately.

✔️ DO Soak the potatoes in cold water and pat them dry thoroughly before baking.
✔️ DO Use freshly shredded cheese instead of pre-shredded to avoid clumping.
✔️ DO Make sure to have an even distribution of cheese and toppings when layering potatoes.
✔️ DO Broil the potato slices for a couple of minutes at the end to achieve a brown and bubbly cheese topping.
Storage
Store any leftover nachos in an airtight container in the refrigerator for up to 3 days. This dish is not freezer-friendly. Reheat in a 400°F oven until warmed through, about 10-15 minutes, to maintain the crispy texture.
Recipe FAQs
Yes, you can prepare the potato slices and toppings in advance. Store the sliced potatoes in a bowl of water in the refrigerator for up to 24 hours to prevent browning. Assemble and bake the nachos just before serving to ensure they remain crispy and fresh.
Popular toppings for potato slices include crispy bacon, sour cream, green onions, jalapeños, pico de gallo, and various types of cheese like cheddar and Monterey Jack. You can also add black beans, diced tomatoes, or avocado slices for extra flavor and texture.
To achieve extra crispy potato nachos, soak the potato slices in cold water for at least 30 minutes, then drain and pat them dry thoroughly. Toss them in olive oil and seasonings before baking at a high temperature, such as 425°F (220°C), and flip them halfway through the baking time to ensure even crisping.
