Instructions
Prepare onion - Heat the oven to 400°F. Use a sharp knife to cut the onion in half at the root. Remove the dry outer layers of onion paper and cut off the tip of the onions. Place the onions on a parchment paper-lined baking sheet cut-side up. Generously drizzle the onions with olive oil and season with salt, freshly ground black pepper, and dried fresh herbs, like rosemary, thyme, sage, parsley, or a blend of choice.
2 medium sweet onions, 2 tablespoon olive oil, kosher or sea salt, freshly ground black pepper, fresh or dried herbs
Roast onions - Bake the onions on the middle rack for 35-45 minutes, or until tender and golden brown, turning over halfway. To test doneness, use a paring knife to pierce into a few layers of the onion through the side. If it goes in easily, the onions are done.
Serve - Transfer the roasted onions to a serving dish and season with more salt, freshly ground black pepper, and herbs, if desired. Enjoy immediately.

Notes
Top Tips
Cut large onions into quarters so they are easier to cook.
Use similar sized onions and don't overcrowd the pan so the onions cook evenly.
Get the olive oil between the onion layers so the layers cook evenly.
Figure out what main course you want to make ahead of time so you can make it while the onions roast.
Use sweetonions, such as Walla Walla, Texas Sweets, Maui, and Vidalia.
If you opt for a medium yellow onion, cook the onion a little longer, as yellow onions have a lower water content than sweet onions and take longer to cook.
