FRIED ONION BURGER RECIPES

Steps:

• Preheat the oven to 250° F. Mix the beef with 1 teaspoon each salt and pepper in a large bowl, then form into 8 balls.
• Heat the vegetable oil in a large skillet over medium-high heat. Add 2 of the beef balls and slightly flatten with a metal spatula. Place a handful of the sliced onions on each patty (you’ll use about a quarter of the onions for 2 patties — it will seem like a lot!) and flatten the beef into 1/4-inch-thick patties, pressing the onions into each burger. Cook until browned on the bottom, about 3 minutes. Carefully flip the burgers along with the onions and cook until the onions are browned and tender, about 2 more minutes. Flip the burgers again, along with the onions, and top each with a slice of cheese. Cover and continue cooking until the cheese melts, 30 seconds to 1 minute. Transfer to a baking sheet and keep warm in the oven until serving.
• Repeat with the remaining beef and onions to make 8 burgers total, adding more vegetable oil to the skillet if needed. Serve 2 burgers on each bun with ketchup, mustard and/or pickles.

Steps:

• "1. Combine onion and 1 teaspoon salt in bowl and toss to combine. Transfer to colander and let set for 30 minutes, tossing occasionally. Tsing tongs, transfer to clean dish towel, gather edges, and squeeze onion dry. Sprinkle with 1/2 teaspoon pepper. 2. Divide onion into 4 separate mounds on baking sheet. Form beef into 4 lightly packed balls and season with salt and pepper. Place beef balls on top of onion mounds and flatten firmly so onion adheres and patties measure 4 inches in diameter. 3. Melt butter with oil in 12-inch nonstick skillet over medium heat. Using spatula, transfer patties to skillet, onion side down, and cook until onion is deep golden brown and beginning to crisp around edges, 6-8 minutes. Flip burgers, increase heat to high and cook until well browned on second side, about 2 minutes. Place1 slice cheese on each bottom bun. Place burgers on buns, add desired toppings and serve."
