  • 6 slices bacon
  • Arugula
  • 3 Buns pretzel buns are my favorite for this burger

Turkey burger:

  • 1 pound ground turkey 85/15%
  • ½ onion grated and drained
  • 1 clove garlic minced
  • 1 teaspoon Worcestershire sauce
  • 1 heaping teaspoon dijon mustard
  • 1 egg lightly beaten
  • ¾ teaspoon salt

Caramelized onions:

  • 3 medium onions sliced into rings (about 4 cups)
  • 2 tablespoons butter divided
  • 2 teaspoons sugar
  • ½ teaspoon salt

Sun-dried tomato mayo:

  • ½ cup sun dried tomatoes drained and squeezed of oil
  • ½ cup mayonnaise
  • 1 clove garlic smashed
  • Salt and pepper to taste
  • Brie cheese small wheel


  • BACON: Preheat oven to 400°F. Cook bacon for 15-20 minutes, until desired crispiness. When bacon is done, turn oven down to 350°F.
  • ONIONS: While the bacon is cooking, start on the onions. Add onions to a pan with 1 tablespoon of butter and salt. Heat on medium low heat, and cook for about 30-45 minutes. Stirring every few minutes, and scraping up any fond that forms on the pan.* If they start to brown too quickly, turn the heat down. You want to slowly caramelize them, not char them. Towards the end of the caramelizing process (about 30 minutes), turn up the heat to medium and add in the rest of the butter and sugar. Cook and stir until the onions are a rich dark brown and jammy. Set aside. 
  • SUN DRIED TOMATO MAYO: Squeeze excess oil from tomatoes. Add ingredients into a food processor and pulse until mostly smooth, but small bits of sun dried tomatoes remain.** Transfer to the refrigerator until you are ready to use it. 
  • TURKEY BURGER: Mix together all ingredients for the burgers except the ground turkey. Then fold in the ground turkey. Don’t over-mix. Loosely form 3 patties. Patties will be loose and wet***. Preheat a pan on medium heat. Add a little bit of olive oil, and sear the burgers on each side, developing a browned crust. Finish off the burgers in the oven for 10-15 minutes, until cooked fully throughout, and center reaches 165°F
  • ASSEMBLE:  When the burgers are finished, turn the broiler on the oven. Lay some sliced brie on top of the burgers and put under broiler for about a minute, watching closely, until cheese is melted. Spread the mayo on one bun and caramelized onions on the other. Add the burger and top with bacon and arugula. 


*The key to making caramelized onions is to let them stick to the pan long enough to start caramelizing them, but not so long that they start to burn. This is why you should be stirring frequently, but not constantly. If the onions are taking too long to brown, add a tablespoon of water to the pan to deglaze while scraping up the fond with a spatula. 
**Don’t over mix the mayo. This may cause it to heat up and break. 
***These burger patties will be loose and wet, and may be difficult to transfer or flip over without breaking. Use a piece of parchment to transfer to the pan, and use 2 spatulas to flip them over. Also these will be large burgers and thick burgers.
