Baked Sliced Onions

1. Preheat Oven

Begin by preheating your oven to 375°F. This moderate temperature ensures that the onions will cook through evenly, allowing them to caramelize beautifully without burning.

2. Prepare Onions

Peel and slice your firm, juicy onions into ¼ inch thick slices. This thickness is ideal for achieving the right balance between tenderness and a satisfying bite.

3. Prepare Baking Sheet

Prepare a baking sheet by brushing it lightly with olive oil. This step prevents the onions from sticking and adds a subtle layer of flavor to the dish.

4. Arrange Onion Slices

Arrange the onion slices on the prepared baking sheet. Sprinkle them with a pinch of salt, then flip the slices over and season the other side as well.

5. Coat with Olive Oil and Salt

Use a brush to coat the top of the onion slices with a little more olive oil and an additional sprinkle of salt. This step aids in the caramelization process, giving the onions a delicious, golden-brown crust as they bake.

6. Bake Onions

Place the baking sheet in the preheated oven and bake the onions for about 30 minutes. During this time, the onions will become tender and develop a rich, sweet flavor. You'll know they're ready when they are tender and browned on the undersides.

7. Serve

Once baked, serve the sliced onions warm or at room temperature. You can enjoy them as they are, or, if you prefer, marinate them briefly in a vinaigrette for an extra burst of flavor.
