Oven roasted potatoes and onions are delightfully crispy and so very tasty. It’s an easy recipe, too: the oven does all the work!
These oven roasted potatoes and onions are a delicacy. They are so flavorful and crispy!
My husband and I are on a low carb diet and don’t eat potatoes anymore (cauliflower is such a wonderful substitute). But our growing kids do eat them, so I make them quite often.
Roasted potatoes are obviously delicious. But add sliced onions, allowing them to slowly caramelize as they roast, and you’ve elevated those roasted potatoes into a whole new level of deliciousness!
It’s such an easy recipe, too. Quickly prep the vegetables, mix with olive oil and spices, then let the oven do all the work.
How do you make crispy potatoes?
It’s all about adding enough fat (olive oil or butter), and about how long you roast them. The recipe below suggests roasting for 45 minutes. But if your oven is not as hot as mine, it might take 5-10 minutes longer.
It’s also important to stir the roasted potatoes and onions after about 20 minutes in the oven. Otherwise, they tend to stick to the bottom of the pan.
If you prefer, you can use melted butter in these oven roasted potatoes and onions. I made it with both olive oil and butter, and both versions were excellent, so it’s really up to you.
What to serve with roasted potatoes and onions?
It’s such a versatile side dish, you can serve it with anything. I like to serve it with something that I can bake in the same oven. So I often serve this side dish with crispy oven baked chicken legs, with baked parmesan chicken or with baked salmon.
Are roasted potatoes and onions healthy?
It depends on your dietary needs. If you need to limit your carbs, then potatoes are probably not the best choice for you. But if you metabolize carbs okay, then yes, I believe this is a healthy recipe. It is made with a short list of real-food ingredients.
It’s also quite nutritious. In addition to the basic nutrition info provided below, a serving has 40% of your daily vitamin C needs, 20% b6, and 11% manganese.
Potatoes can be healthy when eaten in moderation (unless you have a specific issue that requires you to limit carbs), and onions are rich in flavonoids.
What about leftovers?
If you have leftover roasted potatoes and onions, you can keep them, covered, in the fridge for 3-4 days. Gently reheat them in the microwave. Although they won’t be as good as when freshly roasted.
