0 Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper (or foil) and set it aside.
1 Peel the onions by removing the outer layer and inner papery skin. When cutting, you can either slice them in rings (and keep them whole) or split them into half-moon slices (and separate them.) Either way, for even baking, we recommend cutting them into ¼ inch slices.
2 Season them depending on how you cut them:- Cut into rings: Place the red onion rings onto the prepared sheet pan on a single layer. Brush them on both sides with extra virgin olive oil and sprinkle them with salt and pepper (if using.)- Sliced thinly: Gently break apart the slices and place them in a medium-sized bowl. Drizzle with olive oil and sprinkle with salt and pepper. Toss to combine. Spread on the prepared baking sheet on a single layer.
5 Roast, flipping (if you are cooking them as rings) or stirring (if you are baking them as thin slices) until softened and caramelized, for about 20 minutes*.
6 Remove from the oven, and let them cool slightly before using in your recipe.
