What is Oven Fried Potatoes & Onions?

Quick Overview

This recipe is easy because it relies on simple prep and high oven heat to do the work. The potatoes become tender inside while the outside crisps up; onions roast down and caramelize, adding sweet depth. The standout element is the crispy finish you get without deep frying. Total time: about 40 minutes (10 minutes prep, 30 minutes roast). Minimal hands-on time and maximum flavor.

Ingredients

4 medium russet potatoes, peeled and diced into 1/2-inch cubes
1 large yellow onion, chopped
3 tbsp olive oil (or melted butter for a richer flavor)
1 tsp garlic powder
1/2 tsp smoked paprika
1 tsp salt (or to taste)
1/4 tsp black pepper
2 tbsp chopped fresh parsley (for garnish)

Directions

Preheat the oven to 425°F. Prepare a baking sheet by lining it with parchment paper or lightly greasing it with oil or cooking spray for easy cleanup and crispier edges.
In a large mixing bowl, add the diced potatoes and chopped onion. Pour 3 tablespoons olive oil (or melted butter) over the vegetables.
Sprinkle 1 teaspoon garlic powder, 1/2 teaspoon smoked paprika, 1 teaspoon salt, and 1/4 teaspoon black pepper over the potatoes and onions. Toss thoroughly so every piece is coated in oil and seasonings.
Spread the potato and onion mixture in a single layer on the prepared baking sheet. Make sure pieces aren’t piled on top of each other — overcrowding causes steaming instead of roasting. Use two pans if needed.
Roast in the preheated oven for 30 minutes. At the 15-minute mark, stir or flip the pieces to encourage even browning.
For extra crispiness and deeper color, switch the oven to broil for the last 3 to 5 minutes, keeping a close eye to prevent burning. Remove once edges are golden and potatoes are fork-tender.
Transfer to a serving dish and immediately sprinkle with 2 tablespoons chopped fresh parsley to add brightness. Serve hot.

What to Serve With:

Roasted or grilled proteins: chicken thighs, baked salmon, pork chops, or a simple roast chicken.
A leafy green salad with lemon vinaigrette to add acidity and freshness.
Creamy sauces: a dollop of sour cream, chimichurri, or garlic aioli pairs beautifully for dipping.
Eggs for breakfast or brunch: top with a fried egg or serve alongside scrambled eggs and bacon for a hearty morning plate.
Drinks: a crisp white wine, a light beer, or sparkling water with lemon complements the rich roasted flavors.

Top Tips for Perfecting:

Cut uniform pieces: Dice potatoes into consistent 1/2-inch cubes so they cook evenly.
Don’t overcrowd the pan: Give each piece space to brown. Use two baking sheets if necessary.
Swap the fat: Use melted butter for a richer, deeper flavor; olive oil keeps the dish lighter.
Boost the flavor: Add a teaspoon of dried thyme or rosemary with the spices, or a pinch of cayenne for heat.
Watch the broil: The broiler can go from perfect to burnt in seconds. Stay nearby during those final minutes.
Make it extra crispy: After roasting, place potatoes on a wire rack for a few minutes to hold crispness if serving later.

Storing and Reheating Tips:

Refrigeration: Store leftover potatoes in an airtight container in the refrigerator for up to 3 to 4 days.
Freezing: You can freeze roasted potatoes, but texture may change. Freeze in a single layer on a tray first, then transfer to a freezer bag for up to 2 months. Thaw in the fridge before reheating for best results.
Reheating: The oven or a skillet keeps texture best. Reheat at 400°F on a baking sheet for 8–10 minutes or sauté in a skillet over medium heat with a splash of oil until warmed through and crisp. Microwaving will warm them but make them softer, so use that only for convenience.

FAQs

Can I use a different type of potato?
Yes. Yukon gold or red potatoes work well and hold their shape. Russets get crispier edges due to higher starch content.

Can I add other vegetables?
Absolutely. Bell peppers, carrots, or parsnips can be added—cut them similar in size to the potatoes for even cooking.

How do I make them extra crispy?
Use two baking sheets to avoid crowding, toss halfway through, and finish with a 3–5 minute broil while watching closely.

Is this recipe gluten-free?
Yes. The ingredients listed are naturally gluten-free. Always double-check spice labels if you have severe allergies.

Can I prepare this ahead of time?
You can chop potatoes and onions a few hours ahead and keep them in cold water to prevent browning. Drain and dry thoroughly before seasoning and roasting.

What if I only have fresh garlic instead of garlic powder?
Use 1 to 2 cloves of finely minced fresh garlic, added halfway through roasting to avoid burning and to preserve flavor.
