Roasted Salmon with Balsamic Caramelized Onions

What's the trick to this outstanding recipe? Time -- let those onions caramelize over time. If you try to rush things by turning up the heat, the onions will burn before their inherent sweetness comes out. Grab a glass of wine, sit back and let the sugary magic happen!

Roasted Salmon with Balsamic Caramelized Onions

1 tablespoon unsalted butter
1 tablespoon olive oil
2 cups chopped yellow onion
3 tablespoons good quality balsamic vinegar
Cooking spray
4 salmon fillets
Salt and freshly ground black pepper

Heat the butter and oil together in a large skillet over medium heat. Add the onions and cook for 10 minutes, until lightly golden. Add the vinegar and cook for 10 to 15 more minutes, until the onions are very dark brown, stirring occasionally.
Meanwhile, preheat the oven to 400 degrees. Coat a shallow roasting pan with cooking spray.
Season the salmon with salt and pepper and arrange in the prepared pan.
Roast for 15 to 20 minutes, until the fish is fork-tender.
Serve the salmon with the onions spooned over top.

Serves 4
