Ingredients:
- 2 pounds Yukon Gold potatoes, peeled and cut into 1-inch chunks
- 1 large yellow onion, thinly sliced
- 1/4 cup olive oil
- 1 tablespoon garlic powder
- 1 tablespoon onion powder
- 1 teaspoon smoked paprika
- 1/2 teaspoon dried thyme
- 1/2 teaspoon dried rosemary, crushed
- 1/4 teaspoon cayenne pepper (optional, for a little kick!)
- Salt and freshly ground black pepper to taste
- 2 tablespoons grated Parmesan cheese (optional, for extra flavor)
- Fresh parsley, chopped (for garnish)
Preparing the Potatoes and Onions:
- Preheat your oven to 400°F (200°C). This is crucial for getting that crispy exterior we’re aiming for. Make sure your oven is fully preheated before you even think about putting the potatoes in.
- Prepare the potatoes. Peel the potatoes and cut them into roughly 1-inch chunks. Try to keep the pieces relatively uniform in size so they cook evenly. Nobody wants some potatoes that are perfectly cooked while others are still hard!
- Prepare the onions. Thinly slice the large yellow onion. I like to use a mandoline for this to get really even slices, but a sharp knife works just fine. The thinner the slices, the better they’ll caramelize in the oven.
- Combine potatoes and onions. In a large bowl, combine the potato chunks and sliced onions. Make sure you have a bowl big enough to toss everything comfortably without making a mess.
Seasoning and Coating:
- Add the olive oil. Drizzle the 1/4 cup of olive oil over the potatoes and onions. Don’t skimp on the oil it’s essential for getting that crispy, golden-brown texture.
- Add the spices. Now comes the fun part! Sprinkle the garlic powder, onion powder, smoked paprika, dried thyme, dried rosemary, and cayenne pepper (if using) over the potatoes and onions.
- Season with salt and pepper. Generously season with salt and freshly ground black pepper. Don’t be afraid to taste a potato chunk at this point to make sure it’s seasoned to your liking. Remember, you can always add more salt later, but you can’t take it away!
- Toss everything together. Using your hands (or a large spoon), toss the potatoes, onions, oil, and spices together until everything is evenly coated. Make sure every potato chunk and onion slice is glistening with oil and spices. This is key to achieving that delicious flavor and crispy texture.
The Oven-Frying Process:
- Prepare the baking sheet. Line a large baking sheet with parchment paper. This will prevent the potatoes from sticking and make cleanup a breeze. You can also use aluminum foil, but parchment paper tends to work better for preventing sticking.
- Spread the potatoes and onions in a single layer. Spread the seasoned potatoes and onions in a single layer on the prepared baking sheet. It’s important not to overcrowd the pan, as this will cause the potatoes to steam instead of roast. If necessary, use two baking sheets.
- Bake in the preheated oven. Place the baking sheet in the preheated oven and bake for 30 minutes.
- Flip the potatoes and onions. After 30 minutes, carefully remove the baking sheet from the oven and flip the potatoes and onions using a spatula. This will ensure that they cook evenly on all sides.
- Continue baking. Return the baking sheet to the oven and continue baking for another 20-30 minutes, or until the potatoes are tender and golden brown and the onions are caramelized. Keep an eye on them, as cooking times may vary depending on your oven. You want them to be nicely browned and crispy, but not burnt.
- Check for doneness. To check if the potatoes are done, pierce them with a fork. They should be tender and easily pierced. The onions should be soft and caramelized.
Optional Finishing Touches:
- Add Parmesan cheese (optional). If you’re using Parmesan cheese, sprinkle it over the potatoes and onions during the last 5 minutes of baking. This will give them a delicious cheesy crust.
- Garnish with fresh parsley. Once the potatoes are done, remove them from the oven and garnish with fresh chopped parsley. This adds a pop of color and freshness.
Serving Suggestions:
- Serve immediately. These oven-fried potatoes and onions are best served immediately while they’re still hot and crispy.
- Pair with your favorite dishes. They make a great side dish for grilled meats, roasted chicken, or even a simple veggie burger.
- Enjoy! Most importantly, enjoy your delicious homemade oven-fried potatoes and onions!
Tips for Perfect Oven-Fried Potatoes and Onions:
- Use the right potatoes. Yukon Gold potatoes are my favorite for this recipe because they have a creamy texture and hold their shape well during baking. Russet potatoes will also work, but they tend to be a bit drier.
- Don’t overcrowd the pan. As mentioned earlier, it’s crucial not to overcrowd the baking sheet. If you do, the potatoes will steam instead of roast, and you won’t get that crispy exterior.
- Adjust the seasoning to your liking. Feel free to adjust the spices to your personal preference. If you like things spicy, add more cayenne pepper. If you prefer a more savory flavor, add more thyme or rosemary.
- Use high heat. Baking the potatoes at a high temperature (400°F/200°C) is essential for getting them crispy.
- Don’t be afraid to experiment. This recipe is very versatile, so feel free to experiment with different herbs, spices, and toppings. You could try adding some chopped bacon, bell peppers, or even a sprinkle of chili flakes.
Variations:
- Spicy Oven-Fried Potatoes and Onions: Add 1/2 teaspoon of red pepper flakes to the spice mixture for a spicier kick.
- Garlic Parmesan Oven-Fried Potatoes and Onions: Add 2 cloves of minced garlic to the potatoes and onions along with the other spices. Increase the Parmesan cheese to 1/4 cup.
- Herb Roasted Potatoes and Onions: Use a combination of fresh herbs such as rosemary, thyme, and oregano instead of dried herbs.
- Sweet Potato and Onion Oven Fries: Substitute sweet potatoes for the Yukon Gold potatoes for a sweeter and slightly healthier option.
Troubleshooting:
- Potatoes are not crispy: Make sure you’re using enough oil and that you’re not overcrowding the pan. Also, ensure your oven is preheated to the correct temperature.
- Potatoes are burning: Reduce the oven temperature slightly and check the potatoes more frequently.
- Onions are burning: If the onions are browning too quickly, you can add a little bit of water to the baking sheet to prevent them from burning.
- Potatoes are sticking to the pan: Make sure you’re using parchment paper or aluminum foil to line the baking sheet.
Storage and Reheating:
- Storage: Leftover oven-fried potatoes and onions can be stored in an airtight container in the refrigerator for up to 3 days.
- Reheating: To reheat, spread the potatoes and onions on a baking sheet and bake in a preheated oven at 350°F (175°C) for 10-15 minutes, or until heated through. You can also reheat them in a skillet over medium heat.
