Prep time: 10 Minutes
Cook time: 22 Minutes
Serve count: 4
Ingredients
4 (1/4 lb) frozen beef patties (80% lean, 20% fat) 1 yellow onion, thinly sliced 1 tablespoon olive oil 1/2 teaspoon salt 1/4 teaspoon ground black pepper 4 slices Swiss cheese 4 hamburger buns Mayonnaise Mustard Chopped lettuce
Method
How to Make:
- Preheat a greased grill to medium heat.
- In a bowl, toss sliced onions with olive oil, salt and pepper.
- 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.
- Serve burgers immediately.
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.
