Ingredients

  • Olive oil spray (for the baking dish)
  • 2 tablespoons olive oil
  • 2 lb. extra lean ground beef
  • 1 medium onion (finely chopped (6 oz))
  • 2 teaspoons Diamond Crystal kosher salt (or 1 teaspoon fine salt)
  • 1/4 teaspoon black pepper
  • 1 tablespoon minced fresh garlic
  • 1/4 cup avocado oil mayonnaise
  • 1/4 cup unsweetened ketchup
  • 1 tablespoon mustard
  • 1 1/2 cup shredded sharp cheddar (divided (6 oz))

Directions

  1. 1

    Preheat your oven to 400 degrees F. Spray a 2-quart baking dish with olive oil. 

  2. 2

    Heat the olive oil in a large skillet over medium-high heat, about 2 minutes. Add the beef and the onions. Cook, stirring to break up the beef, until the meat is browned and the onion is soft, about 5 minutes. 

  3. 3

    If there are liquids at the bottom of the skillet, carefuly drain the mixture and return it to the skillet. 

  4. 4

    Stir in the kosher salt, black pepper, and garlic. Cook, stirring, 1 more minute.

  5. 5

    Turn the heat off. Stir in the mayonnaise, unsweetened ketchup, mustard, and 1 cup cheddar. 

  6. 6

    Transfer the mixture to the prepared baking dish. Sprinkle with the remaining cheese. 

  7. 7

    Bake until the cheese is melted and the casserole is heated through, about 15 minutes. Or, if your baking dish is broiler-safe, broil the casserole 6 inches below the heating element (not directly below) until the cheese is melted, 1-2 minutes.
