Classic Beef Burgers Caramelized Onions (Printable)
Juicy beef patties with sweet caramelized onions and fresh toppings on toasted buns.
# What You'll Need:
→ For the Caramelized Onions
01 - 2 tablespoons unsalted butter
02 - 2 large yellow onions, thinly sliced
03 - 1 teaspoon sugar
04 - 1/2 teaspoon salt
→ For the Burgers
05 - 1 1/2 lbs ground beef (80% lean)
06 - 1 teaspoon kosher salt
07 - 1/2 teaspoon black pepper
08 - 1 teaspoon Worcestershire sauce
→ For Assembly
09 - 4 burger buns, split
10 - 4 slices cheddar cheese (optional)
11 - Lettuce leaves
12 - Tomato slices
13 - Dill pickle slices
14 - Ketchup, mustard, or mayonnaise as desired
# How To Make It:
01 - In a large skillet over medium heat, melt the butter. Add the sliced onions, sugar, and salt. Cook, stirring occasionally, for 20–25 minutes until onions are golden brown and caramelized. If needed, add a splash of water to prevent sticking. Remove from heat and set aside.
02 - In a large bowl, gently mix the ground beef with salt, pepper, and Worcestershire sauce. Form into 4 equal patties, making a slight indentation in the center of each for even cooking.
03 - Heat a grill, grill pan, or skillet over medium-high heat. Cook the patties for 3–4 minutes per side for medium, or to your desired doneness. If using cheese, place a slice on each patty during the last minute of cooking and cover to melt.
04 - While the burgers cook, lightly toast the buns cut side down in a dry pan or on the grill until golden.
05 - Place lettuce and tomato on the bottom bun, add the burger patty, then top with caramelized onions and pickles. Add ketchup, mustard, or mayo as desired. Top with the other half of the bun. Serve immediately.
# Expert Tips:
01 -
- The patience you put into those onions pays back tenfold in sweet, savory depth that makes every bite feel like a restaurant treat
- These burgers hit that perfect comfort food spot while still being simple enough for a Tuesday night
02 -
- The onion step feels long but rushing it results in cooked onions not caramelized ones, and the difference is everything
- That indentation in the center of each patty saves you from the classic dome shaped burger that slides right out of the bun
03 -
- A splash of balsamic vinegar in the last two minutes of onion cooking adds this bright acidity that cuts through all that rich beef
- Form the patties slightly larger than your buns because they will shrink as they cook, and nobody wants a burger bun overhang situation
