Sliced Potatoes In Oven: How It’s Done
Step 1: Prepare the Potatoes
Start by washing the russet potatoes thoroughly under running water to remove any dirt. Once clean, pat them dry with a kitchen towel.
Step 2: Slice the Potatoes
Using a sharp knife and a cutting board, slice the potatoes into even rounds, about 1/4 inch thick. The key is to keep the slices uniform so they cook evenly.
Step 3: Season the Potatoes
In a mixing bowl, combine the sliced potatoes with olive oil, salt, pepper, garlic powder, onion powder, and dried rosemary if using. Toss everything together until the potato slices are well coated.
Step 4: Arrange on a Baking Sheet
Spread the seasoned potato slices in a single layer on the baking sheet. Make sure they are not overlapping to ensure maximum crispiness.
Step 5: Bake
Place the baking sheet in the preheated oven and bake for 25-30 minutes, flipping the potatoes halfway through. They should be golden brown and crispy when done.
Step 6: Garnish and Serve
Once out of the oven, let the potatoes cool for a few minutes. Garnish with freshly chopped parsley for a pop of color and freshness. Serve warm and enjoy!
If You’re Out Of…
- Olive oil: You can substitute it with any vegetable oil like canola or avocado oil.
- Garlic powder: Fresh minced garlic can be used instead for a stronger flavor.
- Dried rosemary: Try thyme or oregano for a different herbal note.
- Fresh parsley: Chopped green onions or chives can work as a lovely garnish.
Insider Tips
- For extra crispiness, soak the potato slices in water for 30 minutes before seasoning. This helps remove excess starch.
- Experiment with different spices and herbs to find your favorite flavor combination.
- If you want a cheesy touch, sprinkle some grated Parmesan cheese over the potatoes for the last 5 minutes of baking.
- Keep an eye on the potatoes towards the end of the baking time to prevent burning; ovens can vary.
Save for Later: Storage Tips
Leftover sliced potatoes can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply pop them back in the oven at 350°F (175°C) until warmed through and crispy again. Avoid reheating in the microwave as this will make them soggy.
