Ingredients You’ll Need
The beauty of Oven Fried Potatoes & Onions lies in their simplicity—each ingredient brings its own magic to the party, building layers of flavor, texture, and aroma. Here’s what you’ll need and why each one matters:
- Russet potatoes: Their starchy texture turns perfectly crispy on the outside while staying soft inside. Yukon Golds also work beautifully for a buttery bite!
- Onion: Sliced thin, they caramelize and sweeten as they roast, mingling with the potatoes for maximum flavor.
- Olive oil: Ensures everything roasts up golden and helps the seasonings stick.
- Garlic powder: Adds a mellow, savory depth without overpowering the dish.
- Paprika: Brings a gentle smokiness and gorgeous color.
- Salt: Essential for bringing out the flavors of both potatoes and onions—don’t be shy, but taste as you go!
- Black pepper: For a little kick and balance.
- Dried thyme or rosemary (optional): Just a sprinkle takes the aroma to a new level. Use whichever you prefer for an herby lift.
- Fresh parsley (optional): This bright green garnish adds color and a hint of freshness to the finished dish.
How to Make Oven Fried Potatoes & Onions
Step 1: Prep the Oven and Pan
Start by getting your oven nice and hot—preheat to 425°F (220°C). For easy cleanup and to prevent sticking, line a large baking sheet with parchment paper or a silicone mat. This sets the stage for the potatoes and onions to roast evenly and get that coveted crispy edge.
Step 2: Toss Potatoes & Onions with Oil
In a spacious bowl, combine your sliced potatoes and onions. Drizzle in the olive oil and toss everything together, making sure every slice is lightly coated. This not only helps them brown but also gets them ready for an even seasoning.
Step 3: Season Generously
Sprinkle in the garlic powder, paprika, salt, pepper, and dried thyme or rosemary if you’re using it. Toss once more (your hands work great here!) until every piece is dusted with those fragrant spices. The more evenly you coat, the better your Oven Fried Potatoes & Onions will taste.
Step 4: Arrange on the Baking Sheet
Spread your seasoned potatoes and onions out in a single layer on the prepared baking sheet. Try to avoid overlapping too much—this is key for achieving maximum crispiness! If things are crowded, use a second sheet to give them room to breathe.
Step 5: Bake Until Golden and Crisp
Pop the tray in the oven and bake for 30-35 minutes. About halfway through, use a spatula to flip the potatoes and onions—this helps both sides brown up beautifully. Keep an eye out for those deeply golden, crispy edges, which are the hallmark of perfect Oven Fried Potatoes & Onions.
Step 6: Finish with Fresh Parsley
Once everything is roasted to perfection, pull the tray from the oven and, if you like, scatter fresh parsley over the top. It adds a pop of color and a touch of freshness that brightens the whole dish.
Step 7: Serve Hot and Enjoy
Dish up your Oven Fried Potatoes & Onions while they’re still piping hot and irresistibly crispy. They’re a fantastic side for just about any meal—watch them disappear in no time!
How to Serve Oven Fried Potatoes & Onions

Garnishes
Fresh parsley is a classic choice for topping, but don’t be afraid to get creative. A sprinkle of chopped chives or a dusting of parmesan cheese can add extra flair and flavor to your Oven Fried Potatoes & Onions. Even a squeeze of lemon brightens everything up!
Side Dishes
These potatoes pair with just about anything. Serve them alongside roast chicken, grilled steak, or even a veggie-packed omelette. For a brunch spread, they’re unbeatable with eggs and bacon, while at dinner, they soak up gravy from pot roast like a dream.
Creative Ways to Present
While a big platter is always inviting, try piling your Oven Fried Potatoes & Onions into individual ramekins for a dinner party, or nestle them into wraps with grilled sausage for a hearty lunch. They’re even delicious tucked into sandwiches or scattered over a salad for extra crunch!
Make Ahead and Storage
Storing Leftovers
If you find yourself with extra Oven Fried Potatoes & Onions (lucky you!), simply let them cool to room temperature, then transfer to an airtight container. They’ll keep in the fridge for up to 3 days, ready to reheat for another meal.
Freezing
While best enjoyed fresh, you can freeze Oven Fried Potatoes & Onions if needed. Arrange cooled potatoes and onions on a baking sheet and freeze until solid, then transfer to a freezer bag. This way, they don’t stick together and can be reheated straight from the freezer.
Reheating
To bring back maximum crispiness, reheat leftovers in a 400°F (200°C) oven for 10-15 minutes, flipping halfway through. You can use the microwave in a pinch, but the oven or a skillet yields far better texture and flavor.
FAQs
Can I use different types of potatoes for Oven Fried Potatoes & Onions?
Absolutely! While russet potatoes are classic for their crispy texture, Yukon Golds or red potatoes also work well and add a slightly different flavor and creaminess. Just aim for similar thickness when slicing so everything cooks evenly.
Can I add other veggies to this recipe?
Definitely! Feel free to toss in sliced bell peppers, zucchini, or even mushrooms with your potatoes and onions. Just keep the pieces about the same size so they roast at the same rate, and you’ll have a delicious, colorful twist.
What’s the best way to slice potatoes for Oven Fried Potatoes & Onions?
For even cooking, slice your potatoes into 1/4-inch rounds. Using a sharp knife or a mandoline ensures uniform thickness, which is key for that signature crispy texture without burning any pieces.
How do I keep the potatoes from sticking to the pan?
Lining your baking sheet with parchment paper or a silicone mat is the best trick for easy release and cleanup. Also, make sure the potatoes and onions are well coated in oil before baking.
Can I make Oven Fried Potatoes & Onions ahead of time?
You can prep the potatoes and onions, toss them with oil and seasoning, and refrigerate for several hours before baking. For best results, roast them just before serving so they’re at their crispiest!
