- 1 teaspoon salt: Essential for enhancing all the natural flavors and balancing the sweetness of the onions.

How to Make Crispy Oven Fried Potatoes and Onions: A Classic Side Dish Recipe
Step 1: Preheat the Oven and Prepare Your Baking Sheet
Begin by heating your oven to 425°F (220°C). This high temperature is key for getting that sought-after crisp on the potatoes. If you want to avoid sticking and make for easier cleanup, line a large baking sheet with parchment paper. It’s a simple step that can make your life so much easier.
Step 2: Toss Potatoes and Onions with Oil and Seasonings
In a big bowl, combine the thinly sliced or cubed red potatoes and finely chopped onions. Drizzle over the vegetable oil and sprinkle the salt, black pepper, and your choice of optional spices like garlic powder or paprika. Give everything a good toss until every piece is gleaming with oil and seasonings are evenly distributed. This helps ensure that each bite will be bursting with balanced flavor and that gorgeous golden color you’re aiming for.
Step 3: Arrange the Potatoes and Onions on the Baking Sheet
Spread the coated potatoes and onions out in one even layer on your prepared baking sheet, making sure to leave a little space between each piece. Crowding the pan too much can make the potatoes steam instead of crisping up, so give them room to breathe for the best texture.
Step 4: Bake Until Crispy and Caramelized
Pop the baking sheet in the oven and bake for 45 to 50 minutes. Halfway through, give the potatoes and onions a stir or toss to make sure they crisp evenly on all sides. By the time they’re done, the potatoes will have a beautiful golden crust, and the onions will be soft, sweet, and caramelized. Your kitchen will smell incredible!
Step 5: Final Seasoning and Serve Hot
Once out of the oven, taste and adjust the seasoning if needed, adding a pinch more salt or pepper to bring everything into perfect harmony. Serve these Crispy Oven Fried Potatoes and Onions: A Classic Side Dish Recipe hot, straight from the pan, to enjoy that fresh crunch and sweet onion flavor at its peak.

Garnishes
To elevate your crispy side, consider sprinkling fresh herbs like chopped parsley, thyme, or chives right before serving.

A little grating of Parmesan cheese or a squeeze of fresh lemon juice can also add unexpected yet delightful layers of flavor.
Side Dishes
This Crispy Oven Fried Potatoes and Onions: A Classic Side Dish Recipe pairs wonderfully with roasted meats, grilled fish, or even vegetarian mains like sautéed mushrooms or a fresh green salad.

Creative Ways to Present
Try serving these potatoes and onions in a rustic cast-iron skillet for a charming, homey vibe that keeps the dish warm at the table.

For a fun twist, toss in some chopped bell peppers or cherry tomatoes before baking for pops of color and extra sweetness.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers (and often there are!), let the potatoes cool completely before transferring them to an airtight container. Stored in the refrigerator, they will keep well for up to 3 days while maintaining most of their delicious texture.
Freezing
While this dish is best enjoyed fresh, you can freeze leftovers by flash-cooling the potatoes and onions, then sealing them in a freezer-safe container or bag. Frozen leftovers should ideally be eaten within one month for the best taste and texture.
Reheating
To bring back that unbeatable crispness when reheating, spread the leftovers on a baking sheet and pop them into a preheated 400°F oven for about 10-15 minutes. Avoid the microwave if you want to retain maximum crunch and flavor.
FAQs
Can I use other types of potatoes?
Absolutely! While red potatoes work wonderfully here due to their balance of creaminess and firmness, Yukon Gold or Yukon Gold-red potato blends are also excellent choices, offering a buttery taste and good texture for roasting.
Do I need to peel the potatoes?
No peeling necessary! The skins add extra flavor and texture once roasted, plus they’re packed with nutrients. Just make sure to wash the potatoes thoroughly before slicing or cubing them.
Can I make this recipe gluten-free?
Yes! This Crispy Oven Fried Potatoes and Onions: A Classic Side Dish Recipe is naturally gluten-free as long as your seasonings and optional spices are gluten-free. Always check labels if you’re adding any pre-mixed or packaged ingredients.
Is it possible to make this dish spicy?
Definitely! Add a pinch of cayenne pepper, smoked paprika, or chili flakes when tossing your potatoes and onions in oil and seasoning. It gives the dish a lovely warm heat that pairs beautifully with the crispy potatoes.
How do I get the potatoes extra crispy?
The key is to use enough oil to coat everything well and to avoid crowding the baking sheet. Also, flipping or stirring the potatoes about halfway through baking helps them brown evenly on all sides for maximum crispness.
