Enjoy the naturally sweet flavors of onions in this simple baked onions recipe! It only takes a few ingredients and steps to transform an everyday staple into a tender, caramelized side dish.
Prep Oven: Preheat the oven to 400°F (204°C) and line a baking pan with aluminum foil.
Prep Onions: Slice off each end of the onions. Cut the onions in half or quarters crosswise. Peel off the outer layers of the onions. Arrange the onions in a single layer on the prepared baking sheet. The onions should fit comfortably without being crowded.
Season: Brush each onion half with olive oil. You can use a brush or your fingers to ensure the oil covers the entire onion surface. Brush each onion half with olive oil. Season the onions generously with salt (and pepper if you'd like). If you're using herbs, sprinkle them over the onions now.
Bake: Bake the onions for 40 to 45 minutes, or until they're tender and caramelized. Once done, remove the onions from the oven and let them cool for a few minutes before serving.
