This recipe is perfect for any meal, adding a crispy and flavorful touch to your dining experience. The simplicity of the ingredients and the ease of preparation make it a go-to option for busy weeknights or casual gatherings.
Most of the ingredients for this recipe are common pantry staples. However, if you don't usually keep parmesan cheese on hand, you might need to pick some up at the supermarket.

Ingredients for Oven Roasted Parmesan Potatoes
Potatoes: The main ingredient, providing a starchy base that crisps up beautifully in the oven.
Olive oil: Helps to coat the potatoes evenly, ensuring they roast to a golden brown.
Parmesan cheese: Adds a rich, savory flavor and helps create a crispy crust on the potatoes.
Garlic powder: Infuses the potatoes with a subtle, aromatic garlic flavor.
Salt: Enhances the overall taste of the dish.
Black pepper: Adds a touch of heat and depth to the flavor profile.
Technique Tip for This Recipe
To ensure your potatoes roast evenly and achieve that perfect golden crispiness, make sure to cut them into uniform diced pieces. This allows for consistent cooking and prevents some pieces from being undercooked while others are overdone. Additionally, avoid overcrowding the baking sheet; giving each piece enough space ensures they roast rather than steam. For an extra layer of flavor, consider adding a sprinkle of fresh herbs like rosemary or thyme during the last 10 minutes of roasting.
Suggested Side Dishes
Alternative Ingredients
potatoes - Substitute with sweet potatoes: Sweet potatoes offer a slightly sweeter flavor and a different nutritional profile, adding variety to the dish.
olive oil - Substitute with avocado oil: Avocado oil has a higher smoke point and a neutral flavor, making it a good alternative for roasting.
grated parmesan cheese - Substitute with grated pecorino romano: Pecorino romano provides a similar salty and umami flavor but with a slightly sharper taste.
garlic powder - Substitute with minced fresh garlic: Fresh garlic offers a more robust and aromatic flavor compared to garlic powder.
salt - Substitute with sea salt: Sea salt can provide a more complex flavor profile and is often less processed than table salt.
black pepper - Substitute with white pepper: White pepper has a milder flavor and can be used if you prefer a less pungent taste.

How to Store or Freeze This Dish
- Allow the potatoes to cool completely before storing. This prevents condensation, which can make them soggy.
- Transfer the cooled potatoes to an airtight container. This helps maintain their crispiness and flavor.
- Store the container in the refrigerator. The potatoes will stay fresh for up to 3-4 days.
- For longer storage, place the potatoes in a single layer on a baking sheet and freeze until solid. This prevents them from sticking together.
- Once frozen, transfer the potatoes to a freezer-safe bag or container. Label with the date for easy tracking.
- When ready to reheat, preheat your oven to 375°F (190°C). Spread the frozen potatoes on a baking sheet in a single layer.
- Bake for 15-20 minutes, or until heated through and crispy. Stir halfway through to ensure even reheating.
- Alternatively, reheat in an air fryer at 350°F (175°C) for 10-15 minutes, shaking the basket occasionally for even crispiness.
- Avoid microwaving as it can make the potatoes soggy and lose their delightful texture.
How to Reheat Leftovers
- Preheat your oven to 375°F (190°C). Spread the leftover potatoes on a baking sheet in a single layer. Bake for 10-15 minutes until they are heated through and crispy again.
- Use a skillet on medium heat. Add a small amount of olive oil and toss in the potatoes. Stir occasionally for about 5-7 minutes until they are warmed up and regain their crispiness.
- For a quick method, use a microwave. Place the potatoes in a microwave-safe dish and cover them with a damp paper towel. Microwave on high for 1-2 minutes, checking and stirring halfway through. Note that this method may not retain the crispiness as well as the oven or skillet.
- If you have an air fryer, preheat it to 350°F (175°C). Place the potatoes in the basket in a single layer and cook for 3-5 minutes, shaking the basket halfway through to ensure even reheating. This method helps maintain their crispy texture.
