- Cook onion on grill until they are softened and browned, stirring often, about 10 minutes. Set onions aside while you grill the beef patties.
- Cook beef patties until charred and fully cooked through, about 4-5 minutes per side. Adjust grill temperature as needed. Internal temperature should register 160°F on an instant read thermometer.
- Top beef patties with swiss cheese during the last minute of cooking.
- To assemble burgers, add mayonnaise and mustard to buns and fill with lettuce, beef patties with cheese, and grilled onions.

- Notes: If your grill has wide grates, cook onions in a grill basket or on a greased sheet of aluminium foil. No need to thaw beef patties before cooking.
