Ingredients You’ll Need
Don’t be fooled by the simplicity of this ingredient list; each component is essential to achieving the irresistibly crispy, cheesy delight that makes this dish a winner. From the earthy potatoes to the nutty Parmesan, every ingredient plays a role in building flavor and texture.
- 4 medium yellow potatoes: These hold their shape beautifully and offer a creamy texture inside.
- 3 tablespoons olive oil: For a luscious crispness and a subtle fruity richness to the slices.
- ¼ teaspoon garlic powder: Adds a gentle savory note without overpowering the potatoes.
- ¼ teaspoon onion powder: Enhances the depth of flavor and sweetness.
- ¼ teaspoon black pepper: For just a whisper of heat and complexity.
- ½ teaspoon dried parsley: Brings a fresh, herbaceous touch to brighten each slice.
- ½ teaspoon salt (or to taste): The seasoning that elevates every other ingredient.
- 4 tablespoons shredded Parmesan cheese, divided: This layers in a sharp, nutty, crispy crust that makes these potato slices unforgettable.
How to Make Oven Baked Potato Slices with Parmesan Recipe
Step 1: Prepare Your Oven and Equipment
First things first, get your oven preheated to a toasty 450 degrees Fahrenheit. Line a rimmed baking sheet with parchment paper—this step ensures your potato slices won’t stick and cleanup will be a breeze. Trust me, this small prep makes all the difference in the final texture.
Step 2: Slice and Season the Potatoes
Grab a mandoline or a sharp knife and slice those beautiful yellow potatoes into thin, even ¼-inch rounds. Consistency here means even cooking and crispiness across the board. Toss the slices gently but thoroughly in olive oil, then sprinkle on garlic powder, onion powder, black pepper, dried parsley, salt, and half the Parmesan cheese. This mixture coats each slice with a flavorful blanket that will crisp up nicely in the oven.
Step 3: Bake Until Golden and Crispy
Arrange the potato slices in a single layer on your prepared baking sheet. It’s important they don’t overlap—crowding them will cause soggy spots instead of that delicious crisp. Bake them for 20 to 25 minutes, flipping halfway through around the 10-minute mark. You’re aiming for a gorgeous golden hue and edges that have just begun to brown.
Step 4: Add the Final Cheese Touch
Once the slices look perfectly browned, sprinkle on the remaining Parmesan cheese. Return the baking sheet to the oven for another 3 minutes. This last step melts the cheese into bubbling, golden brown little crowns atop each slice, sealing in flavor and adding irresistible crunch.
How to Serve Oven Baked Potato Slices with Parmesan Recipe
Garnishes
These slices are fantastic served plain, but a sprinkle of fresh herbs like chopped chives, rosemary, or even a little extra parsley can give a refreshing lift. A light drizzle of lemon-infused olive oil or a dab of sour cream on the side adds a lovely creamy contrast to the crisp potatoes.
Side Dishes
Oven Baked Potato Slices with Parmesan Recipe pairs wonderfully with grilled chicken or fish for a balanced meal. They’re also an amazing side for a juicy burger or alongside a fresh green salad for a comforting lunch. The cheesy, crispy texture complements countless dishes, adding a satisfying crunch every time.
Creative Ways to Present
Tired of the usual chip bowl? Try stacking the slices with alternating layers of marinara sauce and fresh basil leaves for a fun take on crispy potato “lasagna.” Or serve them on a platter with dollops of garlic aioli or your favorite dipping sauces to turn snack time into a mini party.
Make Ahead and Storage
Storing Leftovers
If you happen to have any leftovers (though it’s hard to believe), store them in an airtight container in the refrigerator for up to 3 days. To keep the best texture, try reheating in the oven or a toaster oven rather than the microwave to revive that crispiness.
Freezing
Freezing Oven Baked Potato Slices with Parmesan Recipe is not ideal due to the crisp texture, but if you want to save them, flash freeze the slices on a baking sheet first, then transfer to a sealed container. They will keep for up to one month, though reheating may not bring back the original crunch completely.
Reheating
To bring leftover slices back to life, spread them out on a baking sheet and warm in a preheated oven at 375 degrees Fahrenheit for about 10 minutes. This helps restore their crunchy exterior better than any microwave method.
FAQs
Can I use a different type of potato for this recipe?
Absolutely! While yellow potatoes work best for their creamy texture and flavor, russets or red potatoes can also be used. Just keep in mind that the texture may vary slightly, with russets becoming crispier and red potatoes holding a firmer bite.
Is it necessary to peel the potatoes?
Not at all! Leaving the skin on adds extra texture, color, and nutrition to the dish. Just be sure to scrub the potatoes well before slicing to remove any dirt or debris.
Can I add other spices or herbs to the recipe?
Definitely! This recipe is very adaptable. Feel free to experiment with smoked paprika, cayenne pepper for heat, or fresh herbs like thyme and rosemary for added aromatic layers.
What’s the best way to get the slices evenly crispy?
Uniform ¼-inch slices are key, along with arranging them in a single layer without overlapping on the baking sheet. Flipping halfway through baking gives both sides the chance to crisp evenly.
Can I make this recipe vegan-friendly?
Yes! Simply omit the Parmesan cheese or substitute it with a vegan cheese alternative or nutritional yeast to maintain that cheesy flavor without dairy.
Final Thoughts
This Oven Baked Potato Slices with Parmesan Recipe is one of those simple pleasures that never fails to bring joy to the table.
