- 1 pound ground beef

- ½ teaspoon ground black pepper
Bun & Toppings:
- 4 hamburger buns of choice

- 4 bacon slices cooked

- romaine lettuce
Instructions
- Balsamic Mayo: In a small bowl, add ½ cup mayo and 4 teaspoons balsamic vinegar. Mix to combine, cover and set in the fridge until ready to use.
- Make Caramelized Onions: Bring a large cast iron skillet to medium-high heat. Add 1 tablespoon extra virgin olive oil and move it around, so that the bottom of the pan is coated. Add sliced onions and sprinkle with ½ teaspoon kosher salt and ½ teaspoon ground black pepper. Move onions around the pan and bring heat down to medium heat once onions start to cook down. Continue cooking onions 15-30 minutes, until they start to turn golden brown. Once onions are a nice brown color, turn off the heat, and set aside until burgers are ready.
- Prep Grill: Preheat the grill to a medium-high heat and make sure the grill grates are clean.
- Prep Burgers: Place 1 pound ground beef, 1 teaspoon kosher salt and ½ teaspoon ground black pepper in a mixing bowl and mix with your hands to combine. Divide into 4 equal burger patties. Make a small thumb indent in the middle of each burger. Sprinkle the tops of the burgers with a little more salt and pepper.
- Grill Burgers: Place the seasoned burgers directly on the hot grates and cook over direct heat for 3-4 minutes on each side (6-7 minutes total). This will result in a medium-rare center. If you want cheese, place a slice of cheese on each burger for the last 1-2 minutes of cook time. Remove and let rest for 5 minutes.
- Assemble Burgers: Place a cooked burger on the bottom bun, add your desired toppings, including some of the caramelized onions and balsamic mayo. Then the top bun.
- Serve: Enjoy right away with any of your favorite side dishes!
Notes
- Whole30/Paleo: double check the ingredients for the balsamic vinegar, mayo, bacon and pickles. Serve on a lettuce bun.
- Burger Cook Times: For Medium: cook 3 minutes on the first side and 5 minutes on the second side. For Medium-Well cook 3 minutes on the first side and seven minutes on the second side. For Well-Done cook for 4 minutes soon the first side and six minutes on the second side.
- Sliders: Simply double the burger ingredients to make 12 sliders. Place the 12 small, flattened patties on a wire rack that is on top of an aluminum foil-lined baking sheet. Broil on high in the oven for 10 minutes. Let rest for 5 minutes and then serve on small buns with all the toppings.
- Storage: leftover burgers can be kept in an airtight container for 3-4 days. Store separately from the toppings and mayo for easier reheating.
