Juicy Double Beef Burger (Printable Version)

Tender double beef patties, caramelized onions, melted cheese, and toasted brioche come together for a hearty meal.

# Ingredients:

→ Beef Patties

01 - 900 grams ground beef (80% lean, 20% fat)
02 - Salt and pepper to taste

→ Caramelized Onions

03 - 4 large yellow onions, thinly sliced
04 - 60 grams unsalted butter
05 - 30 milliliters olive oil
06 - Pinch of salt

→ Cheese

07 - 8 slices Swiss cheese
08 - 4 slices cheddar cheese, thinly sliced

→ Buns and Garnish

09 - 4 brioche burger buns
10 - Fresh chives, chopped, for garnish

# Steps:

01 - Heat butter and olive oil in a large skillet over medium-low heat. Add thinly sliced onions with a pinch of salt and cook gently, stirring occasionally, for 30 to 40 minutes until deeply golden and tender without burning.
02 - Divide ground beef into eight equal portions and shape each into thin patties approximately 5 to 7 cm in diameter. Season both sides generously with salt and pepper. Press a small indentation in the center of each patty to prevent puffing during cooking.
03 - Preheat a grill pan or heavy skillet over medium-high heat. Cook patties for 3 to 4 minutes per side until medium doneness. During the last minute, top each patty with a slice of Swiss or cheddar cheese, cover, and allow cheese to melt.
04 - Slice buns in half and toast cut sides in a dry skillet or under a broiler until golden brown and crisp to prevent sogginess.
05 - Place bottom bun on plate, layer with one cheesy patty, a generous portion of caramelized onions, the second cheesy patty, more onions, then top with the bun. Garnish with chopped fresh chives and serve immediately.

# Notes:

01 - Cooking onions slowly over medium-low heat develops a sweet, rich flavor essential to the dish.
02 - Allow ground beef to come to room temperature before shaping patties for even cooking.
03 - Avoid pressing patties while cooking to retain juiciness.
04 - Toast buns just before serving to maintain crispness.
05 - Leftover patties can be refrigerated for two days and reheated gently to preserve flavor.
