Roasted Red Onions
Description
This recipe uses thinly sliced large red onion rounds tossed evenly with avocado oil and seasoned with kosher salt, crushed black pepper, and garlic powder. The slices are spread evenly in a baking dish or cast iron skillet and roasted at 400°F. The heat gently softens and caramelizes the onions while edges crisp, developing a rich sweetness characteristic of roasted red onions.
The use of avocado oil is intentional for its high smoke point allowing baking at 400°F without burning, though olive oil can be substituted with an adjusted lower temperature and longer roasting time. Using a cast iron skillet can promote crisper edges when oiled sufficiently to prevent sticking.
These onions can serve as a side dish, topping for burgers or salads, or a savory snack, bringing layers of flavor with minimal effort.
Ingredients
- 1 red onion large, sliced into thin circles
- 1 tablespoon avocado oil
- 1 teaspoon kosher salt
- ½ teaspoon black pepper crushed
- ½ teaspoon garlic powder
Instructions
- Wash and peel one large red onion. Slice off the root edges, and cut them into two halves. Then, slice each half into ¼-inch thick slices. Use your fingers or a fork to separate the slices into thin rings.
- Preheat the oven to 400°F. While the oven is heating, spread the onion slices / rings evenly, neatly spaced out in an oven-proof baking dish or a cast iron skillet. Toss the slices with avocado oil, and toss to coat. Then, add a teaspoon of salt, and ½ teaspoon each of black pepper and garlic powder and use your hands or a fork to toss them and spread them out evenly.
- Roast the onions for about 10 minutes. Then, stir once and then continue roasting for another 10 or so minutes, until the onions are tender and caramelized, and starting to get crispy on the sides! Serve as a side or snack!
Notes
- Red onions roast sweeter than yellow, but yellow onions can be used with adjusted roasting time and temperature.
- Avocado oil's high smoke point suits high-temperature roasting; olive oil requires lowering oven heat and longer roasting.
- Use a well-oiled cast iron skillet for crispier onion edges but prevent sticking by coating the pan surface thinly with oil.
