2 yellow onions

1 tbsp avocado or olive oil

Sea salt to taste

1 pound ground beef (shaped into 4 patties about 3/4″ thick)

4 slices cheddar cheese (optional, omit for dairy-free and Paleo)

8 leaves green leaf lettuce (washed and dried) or 2 small heads iceberg lettuce if preferred

2 tomatoes (sliced, about 10 ounces)

4 dill pickles (thinly sliced)

2 tsp yellow mustard

Secret Sauce:

1/4 cup mayonnaise (avocado oil mayo recommended)

2 tbsp ketchup (sugar-free ketchup preferred)

1 tbsp pickle relish (or minced dill pickle for sugar-free)

1/2 tsp white wine vinegar

Optional: maple syrup or coconut aminos to taste


Heat a large pan (10″ or larger) over medium heat. Dice the onions or cut them into half-moon slices.

Add oil to the heated pan along with the sliced onions. Cook over medium or medium-low heat until the onions become softened and browned (about 20-30 minutes). Season with salt to taste and set aside (about 1 cup of caramelized onions).

Preheat the grill or griddle over medium heat (350-400ºF). While the grill heats up, prepare the burger ingredients and mix together the secret sauce.

For the burgers, spread mustard evenly over one side of each patty (about 1/2 tsp per patty).

Grill the burgers for 6-10 minutes per side, adding cheese slices halfway through cooking if desired.

Serve the burgers with lettuce wraps, caramelized onions, sliced tomatoes, pickles, and secret sauce.



For authenticity, use natural yellow cheddar cheese.

Adjust sweetness of secret sauce by adding maple syrup to taste if desired.
