1) Pour olive oil in a skillet and bring the skillet over medium heat. Let the oil get hot.
2) Then add onion slices in the skillet and cook the onion for about 4 minutes so that they turn brown in color.
3) Add half a teaspoon of salt along with sugar and then reduce the heat to low.
4) Cook the mixture over low heat for another 15 minutes until the onion slices are quite golden; do stir the mixture occasionally.
5) Add a teaspoon of Worcestershire sauce and chicken broth in the skillet and cook the mixture for about 8 minutes so that the onions become tender and the liquid is more or less evaporated.
6) Preheat the broiler.
7) Place beef in a bowl and add 2 tbsp of Worcestershire sauce and onion powder; mix well with your hands.
8) Make thick patties out of the mixture and place all the patties over the broiler pan (3/4-inches thick). Make a mark in the center of each of the patties using your thumb. Add salt over the patties according to taste.
9) Broil the patties for about 5 minutes; turn over all the patties and broil again for the same amount of time.
10) Place all the buns on a baking sheet (keeping the cut-side up).
11) Spread gruyere cheese and Parmesan cheese over the buns and broil the buns for about a minute; then spread mustard on the buns.
12) Add lettuce between both the buns, along with the broiled patties and onions.
13) Serve these yummy Onion and Beef burgers with potato chips.
Burgers are great to have – not only a snack or an appetizer but can also be served as a main dish. Onion and Beef Burgers are great to have throughout the year. Cheese, Beef, Onion, Lettuce, and Mustard give these burgers the just perfect taste. The great thing is that you can get these burgers ready in just about 40 minutes or so. I love to serve the patties over hamburger buns but you can also give it a try using whole wheat buns.
