1 lb ground beef
1 white onion
1/2 cup shredded Cheddar cheese
1 tablespoon grated Parmesan cheese
1 egg
1 tablespoon favorite bbq sauce or ketchup
1 tablespoon Worcestershire sauce
1/2 teaspoon salt
1/8 teaspoon pepper
6 hamburger buns, split
Directions
Preheat a grill for high heat.
In a large bowl, mix together the Cheddar cheese, Parmesan cheese, onion, egg, ketchup, Worcestershire sauce, salt and pepper. Crumble in the ground beef, and mix together by hand. Form into 6 patties. Place patties on the grill, and cook for 5 minutes per side, or until well done.
Now a lot of people do not like to add the egg because they feel that it gives the hamburgers a meatloaf flavor. I have done it both ways and they taste the EXACT same, the only difference is that the ones that I made WITH OUT the egg fell apart all over my grill while I was trying the flip them. The ones WITH did not do that.
I have made this recipe enough times that I now just kind of guess how much of each ingredient I am putting in so don't feel bad if you don't use exact measurements.
*Tip for cooking is let them cook for a good long time on the first side because they hold up better when you try to flip. To insure they don't burn cook on a medium low heat.
ENJOY!
