Ingredients
- Onion-mushroom topping:
- 1/2 medium white onion, sliced into1/2-inch-long pieces
- 6 large fresh mushrooms, sliced
- 2 tsp. olive oil
- Burger:
- 1 lb. lean hamburger
- 1/2 tsp. smoked salt
- 1 tsp. pepper
- 1 tsp. olive oil
- 6 Tbsp. mayonnaise
- 6-8 leaves fresh basil, finely chopped
- 6 oz. fresh mozzarella cheese, sliced
- 1 large tomato, sliced
- 4 leaves of Boston lettuce
- 4 large toasted sesame hamburger buns
Directions
-
To make the onion-mushroom topping, cook onions and mushrooms about 15 minutes in olive oil until onions are caramelized. Set aside.
-
For the burger, mix spices and olive oil into meat. Form into 4 patties.
-
Cook hamburgers to preferred wellness (I like medium-rare) on an outside barbecue (my preference), an indoor griddle or on top of the stove.
-
While burgers are cooking, get a bowl and mix mayo and chopped fresh basil together. Set aside.
-
Making the masterpiece one at a time: Take toasted sesame bun, put generous amount of basil/mayo on each side. Stack the burger: one slice fresh mozzarella cheese, one large slice tomato, mushroom-onion mixture and lettuce.
