Ingredients
- 3 tablespoons extra virgin olive oil
- 2 large onions, thinly sliced
- salt pepper
- 3 tablespoons tomato paste
- 3/4 cup dry red wine
- 2 lbs ground sirloin
- 1/2 cup pepperoni, finely chopped
- 1/4 cup fresh flat-leaf parsley, chopped
- 1 teaspoon dried oregano
- 1 teaspoon crushed red pepper flakes
- 4 tablespoons butter
- 3 -4 garlic cloves, finely chopped (or grated)
- 4 slices sesame semolina bread, about 1 inch thick
- 1/2-3/4 cup grated parmigiano-reggiano cheese
- 8 slices provolone cheese (deli slices)
Directions
-
Heat 2 tablespoons oil in a large pan over med-high heat.
-
Add in onions and season with salt and pepper.
-
Cover the onions with a piece of foil and cook, stirring occasionally, until they start to soften, 2-3 minutes.
-
Remove the foil and continue cooking until fully softened, about 5-6 minutes.
-
Add in the tomato paste; cook/stir occasionally, until it smells sweet and has caramelized, 2-3 minutes.
-
Add in the wine and scrape the pan with a wooden spoon to loosen any browned bits that may be stuck to the bottom.
-
Cook until the wine has almost completely evaporated, 1 minute; turn off the heat and reserve.
-
While the onions cook, place a big skillet over med-high heat with the remaining tablespoon of oil.
-
In a big mixing bowl, use your hands to combine the ground sirloin, pepperoni, parsley, oregano, and red pepper flakes.
-
Season the meat with salt and pepper, then score the meat into 4 parts using the side of your hand.
-
Form 4 large patties thinner in the center than at the edges for even cooking and to prevent the burgers from bulging.
-
Cook for 4-5 minutes per side for medium doneness.
-
Preheat the broiler.
-
While the burgers are cooking, heat the butter and garlic together in a small pot over medium heat.
-
When the butter melts, remove the pot from the heat to infuse the butter with the garlic flavor.
-
While the butter is melting, place the bread slices on a baking sheet and toast them under the broiler until golden brown on each side.
-
Brush the toasts with the garlic butter and sprinkle with the grated cheese.
-
Place the toasts back on the baking sheet and top each with one burger.
-
Divide the onion mixture among the four burgers and top each one with two slices of cheese.
-
Slide the burgers under the broiler to melt the cheese, 2-3 minutes.
-
Serve the burgers with a knife and fork, and with your favorite salad on the side.
