Orange-Glazed Salmon With Caramelized Sweet Onions - cooking recipe

Ingredients

2 teaspoons olive oil
2 1/2 - 3 cups thinly sliced sweet onions, such as Vidalia
1/2 teaspoon salt, divided
1/3 cup orange juice
4 teaspoons balsamic vinegar
1 garlic clove, chopped fine
1 teaspoon grated orange peel
1 teaspoon chopped fresh rosemary
2 teaspoons Dijon mustard
2 teaspoons honey
4 salmon fillets, skin removed (1 inch thick)

Preparation

Heat oven to 425\u00b0F Spray 11x7-inch glass baking dish with cooking spray.
Heat oil in large nonstick skillet over medium-high heat until hot. Cook onions and 1/4 teaspoon of the salt 3 to 4 minutes or until onions begin to turn golden brown, stirring frequently. Reduce heat to medium-low and add garlic; cover and cook 5 minutes or until tender, stirring occasionally.
Meanwhile, combine orange juice, vinegar, orange peel and rosemary in small bowl; reserve 2 tablespoons for glaze. Add remaining mixture to onions; cook, uncovered, 2 to 3 minutes or until most of the liquid has evaporated. Whisk mustard and honey into reserved glaze.
Spread onion mixture in baking dish; top with salmon. Sprinkle with remaining 1/4 teaspoon salt; spoon reserved glaze over salmon. Bake 8 to 10 minutes or until salmon just begins to flake. Serve salmon topped with onion mixture.
