Ingredients

To make Roasted Onions, gather the following ingredients:

For the Roasted Onions

• 4 medium onions (yellow, red, or sweet), peeled and cut into wedges
• 2 tablespoons olive oil
• 1/2 teaspoon fine sea salt
• 1/4 teaspoon black pepper
• 1/2 teaspoon dried thyme or rosemary (optional)
• 1 teaspoon alcohol-free balsamic vinegar or lemon juice, for finishing (optional)
• chopped fresh parsley, for garnish (optional)

How to Make Roasted Onions

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). This high temperature is key for achieving those deliciously caramelized edges.

Step 2: Prepare the Baking Sheet

Line a rimmed baking sheet with parchment paper. This will help prevent the onions from sticking during roasting.

Step 3: Toss the Onion Wedges

In a large bowl, toss the onion wedges with olive oil, salt, pepper, and dried herbs (if using) until they are evenly coated.

Step 4: Arrange on Baking Sheet

Spread the onion wedges in a single layer on the prepared baking sheet. Position cut sides down for better caramelization.

Step 5: Roast Until Golden

Roast in the oven for 18–22 minutes until the bottoms are golden. Then flip the wedges using tongs and continue roasting for an additional 15–20 minutes until tender with crisped edges.

Step 6: Finish with Flavor

Remove from the oven and drizzle with alcohol-free balsamic vinegar or lemon juice (if using). Toss lightly in the pan to coat all sides.

Step 7: Garnish and Serve

Garnish with chopped parsley before serving warm. You can also cool them down and refrigerate for up to four days. To reheat, place in an oven at 350°F (175°C) for 8–10 minutes or microwave briefly until warmed through.

Common Mistakes to Avoid

Roasting onions can be simple, but there are common pitfalls to watch out for to ensure perfect results every time.

• Boldly cutting onions unevenly: Ensure your onion wedges are of uniform size for even cooking. This helps in achieving consistent caramelization and tenderness.

• Boldly overcrowding the baking sheet: Give your onions enough space on the baking sheet. Overcrowding can lead to steaming instead of roasting, preventing that lovely golden color.

• Boldly skipping the preheating step: Always preheat your oven before roasting. A hot oven is key to achieving crispy edges and deep caramelization.

• Boldly neglecting the seasoning: Don’t skimp on salt and pepper! These enhance the natural sweetness of the onions. Taste and adjust as needed before roasting.

• Boldly forgetting to flip: Flipping your onion wedges midway through roasting is crucial. It ensures both sides get beautifully caramelized and prevents burning.
