From AllRecipes.com I made “Onion and Cheddar Burgers”
My brother-in-law, now deceased and unable to give me his grand recipe, used to make hamburgers the way my mom made meatballs. All kinds of stuff like egg, onion and oregano they both used, but Jimmy used all of the ingredients below, and then some. My changes are in parenthesis, and they were keeping my brother-in-law watching over me, in mind:
Ingredients:
2 pounds ground beef
1 cup chopped onion
1 egg, beaten
1/2 cup ketchup
1 teaspoon salt
1/2 teaspoon pepper (I skipped the salt and pepper as I added Jimmy’s secret ingredient instead: Onion Soup Mix.)
1/4 teaspoon dried oregano
1 tablespoon Worcestershire sauce
3/4 cup shredded Cheddar cheese (We attributed the moistness of the burgers to the cheese. And even though I may have lost some of the meat during the “flipping”, they tasted like the juicy end of a well-prepared meat loaf.)
6 (toasted) hamburger buns
Directions:
In a large bowl, combine beef, onion, egg and ketchup. Season with salt, pepper, oregano, and Worcestershire sauce. Lightly mix in cheddar cheese. Shape beef mixture into 6 thick patties.
Preheat oven on broiler setting.
Place hamburgers on broiler pan. Broil, turning once, until cooked through, about 5 minutes per side. Serve on hamburger buns. (I served this with a half bottle of an unremarkable Rose, and later switched to our standby: Domaine de Canton Ginger and Russian Standard vodka martini. One last note, I tried the AllRecipes.com option to size this down to 4 burgers instead of 6, it worked perfectly, though, when it came to using 5/8’s of an egg I tossed the whole puppy in.)
