How to Make Best Garlic Herb Burger with Caramelized Onions

Step-by-Step Cooking Instructions

1. Caramelize the onions:

   • Heat a large skillet over medium-low. Add butter and olive oil.
   • Add onions and salt. Cook, stirring every few minutes, until deep golden and soft, 25–35 minutes.
   • Stir in balsamic and sugar if using. Cook 1–2 minutes more. Set aside.

2. Make the patties:

   • In a bowl, mix beef, garlic, parsley, rosemary, thyme, Worcestershire, Dijon, salt, and pepper. Mix gently until just combined.
   • Divide into 4 equal balls. Form 4 patties about 3/4 inch thick. Press a small dimple in the center of each.
   • Chill 10–15 minutes to help them hold shape.

3. Cook the burgers:

   • Heat a cast-iron skillet or grill over medium-high. Add a little oil.
   • Cook patties 3–4 minutes on the first side. Flip and cook 3–4 minutes more, or until done to your liking (160°F for ground beef).
   • Add cheese in the last minute and cover to melt.

4. Toast buns and mix mayo:

   • Toast buns cut side down in the skillet or on the grill until golden.
   • Stir together mayo, garlic, parsley, lemon, salt, and pepper.

5. Assemble:

   • Spread garlic herb mayo on buns.
   • Add patty, a generous scoop of caramelized onions, and any toppings you like. Close and serve.

Tips for Texture, Timing & Tools

• Do not overmix the meat; it keeps burgers tender.
• The center dimple prevents puffing.
• Cast-iron gives the best crust indoors; preheat well.
• For juicy burgers, aim for 80/20 beef and 160°F internal temp.
• Caramelize onions low and slow; do not rush high heat.
• Rest patties 3–5 minutes before building.
• Lightly butter or oil buns for an even toast.

Storage & Reheating

How to Store It Right

• Store cooked patties in an airtight container, 3–4 days in the fridge.
• Caramelized onions keep up to 1 week in the fridge.
• Freeze cooked patties (wrapped well) up to 3 months. Thaw in the fridge.
• Keep buns at room temp, and toast just before serving.

Reheating Without Losing Flavor

• Skillet: warm patties over medium-low with a splash of water; cover to keep moist.
• Oven: 300°F for 8–10 minutes, covered with foil.
• Air fryer: 320°F for 4–6 minutes.
• Gently reheat onions in a small pan over low heat.

Parsley, rosemary, and thyme are great. You can use dried herbs; use about half the amount of dried compared to fresh.

How do I keep the burgers from falling apart?

Mix gently, form firm patties, and chill before cooking. Make a small center dimple and avoid pressing down while cooking.

How long do caramelized onions take?

About 25–35 minutes over medium-low heat. Stir often. A splash of water can prevent burning if the pan gets dry.
