Ingredients

To make these flavorful 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 temperature is ideal for achieving the perfect caramelization of your onions. Line a rimmed baking sheet with parchment paper to prevent sticking.

Step 2: Toss the Onions

In a large mixing bowl, toss the onion wedges with olive oil, fine sea salt, black pepper, and dried herbs if you’re using them. Ensure each wedge is evenly coated; this will enhance flavor during roasting.

Step 3: Arrange on Baking Sheet

Spread the onion wedges in a single layer on the prepared baking sheet. Position cut sides down; this helps achieve better caramelization as they roast.

Step 4: Roast Until Golden

Roast in the preheated oven for about 18–22 minutes until the bottoms are golden brown. Flip the wedges over and continue roasting for an additional 15–20 minutes until they are tender with crisp edges.

Step 5: Finish with Flavor

Once roasted, remove them from the oven and drizzle with alcohol-free balsamic vinegar or lemon juice if desired. Toss lightly on the pan to ensure even coating.

Step 6: Serve or Store

Garnish with chopped fresh parsley before serving warm. If you have leftovers, cool them down and refrigerate for up to four days. Reheat at 350°F (175°C) for about 8–10 minutes or microwave briefly until warmed through. Enjoy your luscious Roasted Onions!

Common Mistakes to Avoid

Roasting onions can elevate your dishes, but there are common pitfalls to watch for. Here are key mistakes to avoid when making roasted onions.

• Bold phrase: Not Preheating the Oven – Always preheat your oven to ensure even cooking and caramelization of the onions.
• Bold phrase: Overcrowding the Pan – If you place too many onions on the baking sheet, they will steam instead of roast. Spread them out in a single layer for better results.
• Bold phrase: Skipping the Oil – A little olive oil is essential for caramelization. Without it, your onions may dry out or burn.
• Bold phrase: Cutting Onions Unevenly – Uniformly cut onion wedges allow for even cooking. Make sure each piece is roughly the same size.
• Bold phrase: Forgetting Seasoning – Don’t neglect salt and pepper. They enhance the flavor and bring out the natural sweetness of the onions.
