Of course! Roasted Caramelized Onions with Thyme and Butter are a revelation. While traditional stovetop caramelizing can take close to an hour, roasting them in a hot oven deepens their natural sugars with less hands-on effort, resulting in a wonderfully sweet, savory, and tender condiment or side dish.
This method is incredibly easy and fills your kitchen with an amazing aroma.
Oven-Roasted Caramelized Onions with Thyme and Butter
Roasting concentrates the onions’ flavor and gives them beautifully browned, crispy edges.
Prep Time: 10 minutes | Cook Time: 35-50 minutes | Total Time: About 1 hour
Yields: About 1 ½ cups (as a side or condiment)
Ingredients
· 2 large yellow or sweet onions (like Vidalia or Walla Walla), about 1.5 lbs total
· 3 tablespoons unsalted butter, melted (or olive oil for a dairy-free version)
· 1 tablespoon fresh thyme leaves, plus 2-3 extra sprigs for roasting
· 1 tablespoon olive oil
· 1 teaspoon salt
· ½ teaspoon black pepper
· 1 teaspoon balsamic vinegar or apple cider vinegar (optional, for a flavor boost at the end)
Instructions
Step 1: Prepare the Onions
- Preheat your oven to 400°F (200°C).
- Peel the onions and slice them in half from root to stem. Then, slice them into ½-inch thick half-moons or wedges. It’s okay if some layers separate.
· Tip: Slicing with the grain (root to stem) helps them hold their shape better.
Step 3: Season and Roast
