Flavorful, and an easy side dish to prepare, roasted potatoes and onion are perfect to complement any entree.
Why these are great
I can't get enough of this dish. The potatoes are perfectly tender with a delicious brown sear where they rested on the pan during roasting, while the onions transform into tender and sweet strips of heaven. If you love onion flavor, you will love these potatoes because the onions really infuse every bite with pungent perfection.
Ingredients you'll need
- Potatoes - I recommend Yukon gold, they are tender and creamy, but reds can just as easily be substituted.
- Onion - A sweet onion is my personal recommendation, as the sweetness really intensifies during roasting.
- Olive oil - Regular olive oil is better for baking than extra virgin, because it can withstand higher temperatures.
- Red wine vinegar - A generous splash of vinegar adds a subtle tangy bite to brighten the flavor.
- Pepper - Fresh ground pepper is preferable. It has a noticeably better flavor.
- Salt - I recommend table salt over kosher salt because the smaller granules will give you better coverage.
How to make crispy potatoes
The secret to crispy potatoes is tossing them in oil. The oil lightly fries them as they roast, crisping the exterior. However, if you are craving crispy potatoes, Yukon golds aren't the best. Waxy potatoes like Yukons and reds will hold their shape well and have a wonderfully creamy texture, but they will never get as crispy as starchier potatoes like Russets.

How to make them
Chop the potatoes into 1" chunks and do the same with the onion. Add these to a large bowl along with oil, vinegar, and seasoning. Toss to evenly coat then spread of a baking sheet.
Tip: I line my baking sheet with foil for easy cleanup. The potatoes also release from the foil easily after baking.
Roast the potatoes and onions at 400 degrees for 45 minutes. There is no need to flip them during roasting.
How to reheat them
It is best to reheat them in the oven, 10 minutes at 400 degrees will do the trick. Otherwise, you can use the microwave instead, but the texture will not be as good. The length of time needed will vary depending on how many leftovers you are reheating.
Ways to customize this recipe
This recipe is easy to customize with you favorite seasonings and herbs. Fresh thyme in particular would be a great addition. Alternatively, you could add additional seasonings such as garlic powder or paprika. You could even swap out the oil for a more flavorful fat like bacon grease or duck fat.
