Rachael's Burger of the Month: Pizza Onion Burgers


Pizza Onions

  • 2 tbsp. olive oil

  • 2 large onions, quartered and thinly sliced

  • Salt

  • 1 tsp. dried oregano

  • About 1/4 cup tomato paste

  • 1 tsp. Calabrian chili paste or 1 tsp. crushed red pepper

  • ½ cup red wine

  • 1 cup chicken stock or water


  • 1 ½ lb. ground sirloin

  • Kosher salt and black pepper

  • ½ cup fresh flat-leaf parsley, finely chopped

  • 6 tbsp. butter, at room temperature

  • 3 cloves garlic, finely chopped

  • Drizzle of olive oil

  • 4 slices each provolone and mozzarella (from the deli counter)

  • 4 Italian rolls or 4- to 5-inch pieces of soft Italian bread, split

  • Little Gem lettuce leaves, sliced tomato, and basil leaves, for serving


  • Step 1

    In a large skillet, heat the oil, two turns of the pan, over medium. Add the onions; season with salt and the oregano. Cook, stirring often, until very soft, about 20 minutes. Add the tomato paste and chili paste and stir until coated, about 1 minute. Add the wine and stir until evaporated. Add the stock. Reduce heat to low. Let the pizza onions simmer while you make the burgers. 

  • Step 2

    Heat a large cast-iron skillet over medium-high. 

  • Step 3

    In a large bowl, season the beef with kosher salt and black pepper and mix together. Form into 4 patties (thinner in the centers for even cooking). 

  • Step 4

    In a small bowl, mix the parsley, butter, and garlic. 

  • Step 5

    Drizzle the patties with oil. Cook, turning occasionally, 7 to 8 minutes. Top with the garlic butter, then the cheeses. Tent with foil to melt the cheeses. 

  • Step 6

    Top the roll bottoms with lettuce, tomato, basil, and the cheeseburgers. Add the pizza onions and roll tops.
