Ingredients

• 2 tablespoons extra-virgin olive oil
• 2 tablespoons unsalted butter melted (divided)
• 1 ½ tablespoons fresh thyme chopped (divided)
• ½ teaspoon salt
• ½ teaspoon ground pepper
• 3 large sweet onions 12 oz. each, sliced 1 inch thick
• ⅓ cup panko breadcrumbs
• ½ cup low-sodium beef broth
• 1 tablespoon sherry vinegar or apple cider vinegar
• ½ cup shredded Gruyère cheese
• ½ cup shredded mozzarella cheese

Instructions

Prepare the onions for roasting

• Preheat the oven to 450°F (230°C). Place the oven rack in the upper third position.
• In a small bowl, mix:
• 2 tablespoons olive oil
• 1 tablespoon melted butter
• 1 tablespoon chopped thyme
• ½ teaspoon salt and ½ teaspoon pepper
• Arrange the onion slices in a single layer on a metal baking pan (avoid using glass or ceramic, as they may shatter).
• Brush the butter mixture evenly over both sides of the onion slices.

Roast the onions

• Roast for 30 minutes, flipping once halfway, until both sides are golden brown.

Make crispy breadcrumbs

• In the same bowl, combine:
• ⅓ cup panko
• 1 tablespoon melted butter
• ½ teaspoon chopped thyme
• Heat a small nonstick skillet over medium-high heat. Toast the panko, stirring occasionally, for 2-3 minutes until golden brown and fragrant. Set aside.

Soften the onions

• Flip the onions again. Pour in the beef broth and sherry vinegar.
• Roast for another 10 minutes until the broth slightly reduces and the onions become very soft.

Broil with cheese

• Set the oven to broil (about 480°F/250°C).
• Sprinkle the shredded Gruyère and mozzarella evenly over the onions.
• Broil for about 1 minute until the cheese melts and bubbles.

Garnish and serve

• Sprinkle the toasted breadcrumbs on top.
• Garnish with fresh thyme leaves, if desired.
• Serve with the remaining sauce from the pan.
