Why You'll Love This Recipe
About the Ingredients
2 lbs (900g) russet potatoes, scrubbed and thinly sliced (about 1/8 inch thick)
Russets give the crispiest results due to their high starch content. Yukon Golds also work well for a creamier texture.
3 tablespoons (45ml) olive oil
Extra-virgin olive oil adds a fruity note, but any neutral oil like avocado or canola works. For a richer flavor, try melted butter.
3 cloves garlic, minced
Fresh garlic is best, but 1/2 teaspoon garlic powder can substitute in a pinch. Adjust to taste.
1 teaspoon (2g) dried thyme
Dried thyme is convenient; use 1 tablespoon fresh thyme leaves if you have them. Rosemary or oregano are lovely swaps.
1 teaspoon (5g) salt
Use fine sea salt for even distribution. Kosher salt may require a bit more; adjust to your preference.
1/2 teaspoon (1g) black pepper, freshly ground
Freshly ground pepper adds a fragrant kick. White pepper can be used for a milder taste.
2 tablespoons (10g) grated Parmesan cheese (optional)
Parmesan adds a savory, nutty crust. For a dairy-free version, omit or use nutritional yeast.
Fresh parsley, chopped, for garnish
A handful of fresh parsley brightens the dish. Chives or dill also complement the flavors nicely.
Tips & Tricks
Slice potatoes uniformly
Use a mandoline or a very sharp knife to ensure even cooking. Aim for 1/8-inch thickness so all slices crisp at the same rate.
Don't overcrowd the pan
Arrange slices in a single layer, slightly overlapping if needed, but avoid piling them up. Overcrowding traps steam and prevents crisping.
Pat potatoes dry
After slicing, pat them with a clean kitchen towel to remove excess starch and moisture. This helps them crisp rather than steam.
Let them rest after baking
Allow the potatoes to sit for 5 minutes before serving. This lets the steam escape and the edges firm up.
Pro Tips
Step-by-Step Instructions
1. Preheat and Prep
Preheat your oven to 400°F (200°C). Lightly grease a large baking sheet or line it with parchment paper for easy cleanup.
2. Slice Potatoes Thinly
Using a mandoline or sharp knife, slice the potatoes into 1/8-inch thick rounds. Try to keep them uniform so they cook evenly.
3. Toss with Seasonings
In a large bowl, combine the potato slices, olive oil, minced garlic, thyme, salt, and pepper. Toss gently with your hands to coat every slice evenly.
4. Arrange on Baking Sheet
Lay the potato slices in a single layer on the prepared baking sheet, slightly overlapping if necessary. Sprinkle with Parmesan cheese if using.
5. Bake Until Golden
Bake for 25-30 minutes, or until the edges are golden brown and crispy, and the potatoes are tender when pierced with a fork. Rotate the pan halfway through for even browning.
6. Rest and Serve
Remove from the oven and let rest for 5 minutes. Garnish with fresh parsley and serve warm. Enjoy the satisfying crunch!
Delicious Variations
Spicy Paprika
Add 1 teaspoon smoked paprika and a pinch of cayenne to the seasoning mix for a smoky, spicy kick.
Herb Garden
Swap thyme for a mix of fresh rosemary, oregano, and chives, and finish with a squeeze of lemon juice.
Cheesy Delight
Sprinkle shredded cheddar or Gruyère over the potatoes during the last 5 minutes of baking for a melty, cheesy topping.
How to Store Thin Sliced Potatoes In Oven
Refrigerator
Store leftovers in an airtight container in the refrigerator for up to 4 days.
Freezer
Freeze in a single layer on a baking sheet, then transfer to a freezer bag for up to 2 months. Reheat directly from frozen.
Reheating
Reheat in a 375°F (190°C) oven for 5-7 minutes until crispy again. Avoid microwaving, as it makes them soggy.
Frequently Asked Questions
Q: How thin should I slice the potatoes?
Aim for about 1/8 inch thick, roughly the width of a coin. This ensures they cook through and become crispy without burning.
Q: Can I use other types of potatoes?
Yes, Yukon Gold or red potatoes work well. They are slightly waxy, so they may be less crispy but still delicious. Adjust baking time if needed.
Q: Why are my potatoes not crispy?
The most common reasons are overcrowding the pan, excess moisture on the slices, or not baking at a high enough temperature. Ensure slices are dry, spread out, and the oven is fully preheated to 400°F (200°C).
Q: Can I prepare these ahead of time?
You can slice the potatoes and store them in cold water in the fridge for up to 24 hours. Pat them dry before tossing with oil and seasonings, then bake as directed.
