This foolproof roasted potatoes and onions recipe transforms humble ingredients into a side dish that steals the show at every dinner table. This dish delivers restaurant-quality results with minimal effort and maximum flavor.
Ingredients
- 2 pounds baby potatoes or Yukon Gold potatoes, cut into 1-inch chunks
- 2 large yellow onions, cut into thick wedges
- 3 tablespoons olive oil
- 1 teaspoon kosher salt
- ½ teaspoon freshly ground black pepper
- 1 teaspoon garlic powder
- 1 teaspoon dried rosemary (or 2 tablespoons fresh rosemary, chopped)
- ½ teaspoon smoked paprika
- 2 tablespoons fresh parsley, chopped (for garnish)
- Optional: 2 cloves fresh garlic, minced
Cooking Instructions
Preheat your oven to 425°F (220°C) and position the rack in the center.
This high temperature is crucial for achieving that perfect crispy exterior while keeping the inside fluffy and tender. Line a large rimmed baking sheet with parchment paper or lightly grease it with cooking spray to prevent sticking.
Prepare the potatoes by washing them thoroughly and cutting them into uniform 1-inch pieces.
If using baby potatoes, you can halve or quarter them depending on size. The key is maintaining consistent sizing so everything cooks evenly. Pat the cut potatoes completely dry with paper towels – this step is essential for achieving maximum crispiness.
Cut the onions into thick wedges by slicing each onion in half from root to tip, then cutting each half into 4-6 wedges.
Keep the root end intact on each wedge to help them hold together during roasting. The onions will shrink significantly as they cook, so don’t worry if the pieces seem large initially.
In a large mixing bowl, combine the prepared potatoes and onions with olive oil, ensuring every piece is well-coated.
Use your hands to toss everything together – this gives you the best control over even distribution. The oil not only promotes browning but also helps the seasonings adhere to the vegetables.
Season the mixture with kosher salt, black pepper, garlic powder, rosemary, and smoked paprika.
Toss everything together again until the seasonings are evenly distributed. If you’re using fresh minced garlic, add it now, but be aware that it can burn easily, so consider adding it halfway through cooking instead.
Spread the seasoned potatoes and onions in a single layer on your prepared baking sheet.
Avoid overcrowding – the vegetables should have space around them to allow proper air circulation.
If necessary, use two baking sheets rather than cramming everything onto one. Overcrowding leads to steaming instead of roasting, resulting in soggy rather than crispy vegetables.
Roast in the preheated oven for 35-45 minutes, stirring once halfway through cooking.
The exact timing depends on the size of your potato pieces and your desired level of crispiness. Look for golden-brown edges and tender interiors when pierced with a fork.
The onions should be caramelized and slightly charred at the edges.
Remove from the oven and immediately sprinkle with fresh chopped parsley for a pop of color and freshness.
Taste and adjust seasoning with additional salt and pepper if needed. Serve immediately while hot and crispy for the best texture and flavor experience.

Balsamic Glazed Version

The vinegar will caramelize and create a beautiful glaze. Add some red onion for color variation and finish with toasted pine nuts and fresh basil leaves for a gourmet presentation.
FAQs
Can I make this recipe ahead of time?
While roasted potatoes and onions are best served immediately for optimal crispiness, you can prep the vegetables up to 24 hours in advance.
Cut and season them, then store covered in the refrigerator. When ready to cook, let them come to room temperature for 15-20 minutes before roasting. For reheating leftovers, use a 400°F oven for 10-15 minutes rather than the microwave to restore some crispiness.
What’s the best type of potato for roasting?
Yukon Gold potatoes are ideal for roasting because they have a perfect balance of starch and moisture, creating fluffy interiors with crispy exteriors.
Baby potatoes also work wonderfully and look elegant when halved. Avoid russet potatoes for this recipe as they can become too fluffy and may fall apart during the stirring process.
Why aren’t my potatoes getting crispy?
The most common culprits for soggy potatoes are overcrowding the pan, not drying the potatoes thoroughly after cutting, using too low an oven temperature, or not using enough oil.
Make sure your oven is fully preheated to 425°F, pat the potatoes completely dry, use adequate oil to coat all surfaces, and give the vegetables plenty of space on the baking sheet.
Can I add other vegetables to this recipe?
Absolutely! Root vegetables like carrots, parsnips, and turnips work beautifully with similar cooking times. Add Brussels sprouts, bell peppers, or zucchini during the last 20 minutes of cooking since they require less time.
Keep in mind that different vegetables have varying cooking times, so you may need to add them at different stages for even cooking.
How do I store and reheat leftovers?
Store leftover roasted potatoes and onions in the refrigerator for up to 4 days in an airtight container. For the best results when reheating, spread them on a baking sheet and warm in a 400°F oven for 10-15 minutes until heated through and crispy again. You can also reheat them in a skillet with a little oil over medium-high heat, stirring occasionally until warmed and re-crisped.
