Who doesn't love a nice juicy grilled burger? This is a quick and easy recipe for onion burgers just bursting with flavor. Hamburger meat is combined with onion soup mix and Worcestershire sauce, along with ketchup, and then grilled. To achieve those juicy, luscious burgers, you want to use sirloin or ground round and try to get 80 to 85% lean beef

Form the patties, and make sure to press your thumb into the center of each hamburger patty to create an indentation. This helps to keep the burgers from puffing up in the middle. When grilling, avoid the temptation to press down on the burgers with the spatula as that will release the juices, and leave them alone, don't keep flipping them. These tips will further assist you in getting the ideal burger that is juicy and tasty. 

This onion burger recipe offers a special topping for the burgers consisting of mayo and steak sauce and also uses swiss cheese, but you're welcome to change the cheese to whatever your favorite one is, and to use another topping if you'd like. 

Toast the buns on the grill for a crispy effect, or leave them untoasted. Don't forget to put your favorite toppings, such as a combo of lettuce, a slice of tomato and onion, and a pickle.  

These onion burgers are perfect for weeknight meals, tailgating, game day, or cookout. Serve them with homemade french fries or potato salad and baked beans.


  • 2 pounds (900 grams) of ground beef, preferably sirloin or round

  • 1 package dry onion soup mix

  • 1 tablespoon (15 milliliters) Worcestershire sauce

  • 1 tablespoon (15 milliliters) ketchup, or tomato paste

  • 1 teaspoon (5 milliliters) sea salt

  • 6 hamburger buns

  • 6 slices swiss cheese

For the Topping:

  3. Form into six equal-sized patties.
