Yield

Serves: 4

Preparation

Combine balsamic reduction with ketchup and set aside.

Heat a skillet with 2 tablespoons olive oil, 2 turns of the pan. Add onions and season with salt and pepper. Cook over medium low heat to caramel-colored and very sweet, 25-30 minutes, stirring occasionally. Add a touch of water to the pan to keep onions moist.


Preheat a cast-iron skillet or griddle over medium-high heat.

In a bowl, combine beef with wine, garlic, rosemary, sage, salt and pepper. Form 4 patties that are thinner at the center and thicker at the edges for even cooking. Drizzle patties with olive oil and cook 8 minutes, turning once. Top with cheese and melt under dome or tin-foil tent the last minute of cooking time.

Serve burgers on focaccia topped with caramelized onions and a little balsamic ketchup.
