Ingredients Method Notes

Ingredients
  

  • For the burgers:
  • 1 ½ lbs ground beef
  • 2 cloves garlic minced
  • 1 tbsp fresh parsley chopped
  • 1 tsp fresh thyme leaves or ½ tsp dried thyme
  • ½ tsp onion powder
  • Salt and black pepper to taste
  • 1 tbsp Worcestershire sauce
  • 1 tbsp olive oil for grilling or pan-searing
  • For the caramelized onions:
  • 2 large yellow onions thinly sliced
  • 1 tbsp butter
  • 1 tbsp olive oil
  • Pinch of salt
  • 1 tsp balsamic vinegar optional
  • For assembling:
  • Burger buns toasted
  • Sliced cheese optional, such as provolone, Swiss, or cheddar
  • Lettuce tomato, or other desired toppings
  • Condiments of choice

Method
 

  1. In a large bowl, combine ground beef with garlic, parsley, thyme, onion powder, salt, pepper, and Worcestershire sauce. Mix gently until just combined. Form into 4 equal patties.
  2. In a skillet over medium-low heat, heat butter and olive oil. Add sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for 20–30 minutes until deeply browned and caramelized. Stir in balsamic vinegar, if using. Set aside.
  3. Heat a grill or skillet over medium-high heat. Brush with olive oil and cook the burger patties for about 4–5 minutes per side or until they reach your desired doneness. Add cheese during the last minute, if using.
  4. Toast burger buns lightly, then assemble: place the patty on the bottom bun, top with caramelized onions and any desired toppings or condiments, then finish with the top bun.
  5. Serve immediately.

Notes

  • Use 80/20 beef for the juiciest burgers.
  • Mix herbs and garlic gently into the meat—don’t overwork it.
  • Caramelize the onions low and slow for best flavor.
  • Add a splash of balsamic at the end for extra richness.
  • Cheese is optional but highly recommended—provolone or cheddar work great.
  • Toast buns before assembling to keep them crisp.
  • Assemble with your favorite toppings and condiments.
  • Serve with fries, a salad, or as sliders for parties.
  • Store leftovers in the fridge for up to 3 days.
  • Caramelized onions can be made ahead and reheated.
