This recipe was developed and tested at its original yield and has not been tested at other yields. Note that only the ingredient list is scaled, so you may need to make adjustments to ingredient amounts, cooking times and equipment sizes in the recipe steps. Scaling could also impact the nutrition analysis. Original recipe (1X) yields 8 servings 2 tablespoons extra-virgin olive oil 2 tablespoons unsalted butter, melted, divided 1 tablespoon plus ½ teaspoon chopped fresh thyme, divided, plus leaves for garnish ½ teaspoon salt ½ teaspoon ground pepper 3 large sweet onions (12 oz. each), peeled and sliced 1-inch thick ⅓ cup panko breadcrumbs ½ cup lower-sodium beef broth 1 tablespoon sherry vinegar ½ cup shredded Gruyère cheese ½ cup shredded low-moisture part-skim mozzarella cheese Directions Position oven rack in upper third; preheat to 450°F. Whisk 2 tablespoons oil, 1 tablespoon melted butter, 1 tablespoon thyme and ½ teaspoon each salt and pepper together in a small bowl. Arrange sliced onions in an even layer in a broiler-safe, 9-by-13-inch metal baking pan (don’t use glass or ceramic, which might shatter). Brush the butter mixture all over the onions. Do not wipe out the bowl; set aside. Roast the onions, flipping once halfway, until lightly browned on both sides, about 30 minutes. Robby Lozano Meanwhile, in the reserved bowl, combine ⅓ cup panko and the remaining 1 tablespoon melted butter and ½ teaspoon thyme; toss until evenly coated. Transfer to a small nonstick skillet; cook over medium-high heat, stirring occasionally, until fragrant and golden brown, 2 to 3 minutes. Remove from heat and allow to cool until ready to use. Robby Lozano Flip the onions once more. Carefully pour ½ cup broth and 1 tablespoon vinegar into the baking pan. Roast until the broth is slightly reduced and the onions are very soft, about 10 minutes more. Remove from oven. Robby Lozano Increase oven temperature to broil. Combine ½ cup each Gruyère and mozzarella in a small bowl; evenly sprinkle over the onions. Broil until the cheese is melted and bubbling, about 1 minute. Top with the reserved panko mixture. Garnish with thyme leaves, if desired. Serve with any sauce left in the pan.
