Balsamic-Glazed Onion Cheeseburgers with Roasted Potato Wedges
10 Ounces Ground Beef
2 Potato Buns
2 Cloves Garlic
1 Yellow Onion
1 Russet Potato
2 Ounces Monterey Jack Cheese
2 Tablespoons Balsamic Vinegar
1 Teaspoon Whole Dried Rosemary
Preheat the oven to 475°F. Wash and dry the fresh produce. Halve the buns. Cut the potato lengthwise into 1-inch-wide wedges. Peel and small dice the onion. Peel and mince the garlic; using the flat side of your knife, smash until it resembles a paste (or use a zester). Thinly slice the cheese.
Place the potato wedges on a sheet pan. Drizzle with olive oil and season with salt and pepper; toss to thoroughly coat. Arrange in a single, even layer, skin sides down, and roast 30 to 32 minutes, or until browned and tender when pierced with a fork. Remove from the oven.
Once the potato wedges have roasted for about 5 minutes, in a small pot, heat a drizzle of olive oil on medium-high until hot. Add the onion and season with salt and pepper. Cover and cook, stirring occasionally, 5 to 7 minutes, or until lightly browned and softened. Add the vinegar; cook, uncovered, stirring occasionally, 2 to 3 minutes, or until most of the liquid has cooked off and the onion is thoroughly coated. Remove from heat and season with salt and pepper to taste. Set aside in a warm place.
While the potato wedges continue to roast, in a medium bowl, combine the ground beef, garlic paste and as much of the dried rosemary as you’d like; season with salt and pepper. Gently mix to combine. Using your hands, form the mixture into two ¾-inch-thick patties; transfer to a plate.
While the potato wedges continue to roast, in a medium pan (nonstick, if you have one), heat a drizzle of olive oil on medium-high until hot. Add the patties and cook, loosely covering the pan with foil, 2 to 4 minutes on the first side, or until browned. Flip and evenly top with the cheese. Cook, loosely covering the pan with foil, 2 to 4 minutes, or until the cheese has melted and the patties are cooked to your desired degree of doneness. Leaving any browned bits (or fond) in the pan, transfer to a plate. Set aside in a warm place.
While the potato wedges continue to roast, add the buns, cut sides down, to the pan of reserved fond. (If the pan seems dry, add 1 teaspoon of olive oil.) Toast on medium-high 1 to 2 minutes, or until golden brown. Transfer to a clean, dry work surface. Top the toasted bun bottoms with some of the glazed onion (you may have extra onion). Top with the cooked patties. Complete the burgers with the bun tops. Divide the burgers and roasted potato wedges between 2 dishes. Enjoy!
