"I created French Onion Burgers one day when I needed to stretch a pound of hamburger," recalls Beth Johnson of Dalton, Ohio. "When we have high school boys help with baling hay, this is one of their favorite foods to enjoy after the work is done."
Here's a sandwich that does regular burgers one better—with a surprise pocket of cheddar! "The beef patties contain additional popular toppings, including ketchup, mustard and onions," lists Janet Wood of Windham, New Hampshire. "Whenever I serve these, though, folks enjoy finding the melted cheese most."
These burgers are a twist on the traditional backyard favorite. A dollop of dill and horseradish dressing gives extra bite to this standard. They are made with lean ground beef to keep the fat content low, and includes grated carrots and chopped fresh mushrooms to sneak in some veggies.—Deb Anderson, Joplin, Missouri
If you like blue cheese, you'll love the flavorful surprise inside these moist hamburgers from Dee Dee Mitchell of Longmont, Colorado. "They're so filling that just a serving of tangy coleslaw on the side makes for a hearty meal."
