They’re great as a side dish, in a salad, or as a topping for hamburgers and steaks.
Ingredients
You only need three simple ingredients to make this recipe. The exact measurements are listed in the recipe card below. Here’s an overview of what you’ll need: But onions can actually serve as a great side dish. Roasted onions are wonderful, for example. Pickled red onions are good too, although that’s indeed more of a condiment. The same thing happens when roasting garlic. The sharpness is replaced with wonderful creaminess. In both cases - onions and garlic - I’m not a fan of the raw vegetable. But the cooked version is absolutely delicious! Red onion: I haven’t tried making this recipe with white or yellow onions. You can try using yellow onions. But the white ones are quite sharp - I don’t know if they’re good candidates for this recipe. Olive oil: This is my favorite oil and I love cooking with it. But if you’re unsure about cooking with it, you can use avocado oil instead. It has a higher smoke point. Another tasty option is using melted butter. Kosher salt: If using fine salt, you might want to reduce the amount you use or the dish could end up too salty.
Instructions
Roasting red onions is easy! Scroll down to the recipe card for detailed instructions. Here are the basic steps:
Peel the onion, slice it into slices, and separate the slices into rings. The video below shows you how I do it.Now, spread the onion rings in a baking dish. Toss them with some olive oil and sprinkle them with kosher salt.Roast them at 400°F until soft and caramelized, about 20 minutes. That’s it! Super easy. And so tasty!
Expert tip
How do you slice an onion? You wash, dry, and peel it. Then slice it into ¼-inch thick slices and separate the slices into rings. You can also cut them into quarters if you prefer and roast them for a little longer.
Frequently asked questions
Variations
One way to vary this recipe is to use butter instead of olive oil. Another variation, mentioned above, is to add ½ tablespoon of aged balsamic vinegar. This will add flavor and promote caramelizing.
Serving suggestions
These onions make a delightful side to any meat dish, especially to grilled meats. I often serve them with grilled chicken tenders. They are also excellent with baked chicken thighs, and I love being able to roast both dishes in the same oven. Needless to say, they make a great topping for hamburgers!
Storing leftovers
You can keep the leftovers in the fridge, in a sealed container, for 3-4 days. They can be reheated in the microwave, and they taste great - just as good as fresh. I also like to add them the next day to an omelet, or even (cold) to a salad.
