Yeah I know, it sounds like a random assortment of stuff to put in hamburgers. Most people just buy the hamburger patties and throw them on the grill. You are really missing out if you haven’t tried adding other things to the mix.
6 ounces tomato paste
1 Tablespoon Worcestershire sauce
¾ cup red onion, chopped
½ cup Parmesan cheese
½ teaspoon seasoned salt
½ teaspoon salt
2 lbs 80/20 ground beef
Mix all ingredients, except the hamburger together. I like to use the food processor so I don’t have any huge chunks of onion. If you like chunks of onion, just chop it up and mix it in.
Crumble the hamburger in with the other ingredients, mush it all together with your hands until it’s all mixed up.
I usually make 3-4 ounce patties. You can make them bigger, I just have found it is hard to get them to cook all the way through on the grill if they get too big. Makes 8 hamburgers.
Grill over medium heat until the internal temperature is 160.
