  • Olive oil spray for greasing
    2 tablespoons of olive oil
    2 pounds of extra-lean ground beef
    1 medium onion, finely chopped (approximately 6 ounces)
    2 teaspoons of Diamond Crystal kosher salt or 1 teaspoon of any other salt
    ¼ teaspoon of black pepper
    1 tablespoon of fresh garlic, minced
    ¼ cup of mayonnaise
    ¼ cup of unsweetened ketchup
    1 tablespoon of mustard
    1 ½ cups of sharp cheddar cheese, shredded (approximately 6 ounces)


  • Preheat your oven to 400°F and spray a 2-quart baking dish with olive oil.
  • Heat olive oil in a large skillet over medium-high heat for about 2 minutes. Add ground beef and onions, cooking until the beef is browned and the onions are soft (approximately 5 minutes).
