  • 2 tablespoons olive oil
  • 2 lb. extra-lean ground beef
  • 1 teaspoon Diamond Crystal kosher salt
  • 1/2 teaspoon black pepper
  • 2 teaspoons garlic powder
  • 2 teaspoons onion powder
  • 1 teaspoon dried oregano
  • 3 cups marinara sauce, no sugar added (I like Rao's)
  • 6 oz chopped fresh kale (about 3 cups; I use half of a 12-oz bag that I get at Whole Foods)
  • 8 oz shredded mozzarella, divided


  • Preheat your oven to 400 degrees F. Lightly grease a 9 X 13-inch baking dish.
  • In a large, deep skillet, heat the olive oil over medium-high heat, about 2 minutes.
  • Add the ground beef. Cook, stirring to break up and crumble the beef, until no longer raw, about 5 minutes.
  • Lower the heat to medium. Stir in the salt, pepper, garlic powder, onion powder, and oregano.
  • Stir in the marinara sauce.
  • In batches, stir the kale into the mixture, cooking just until it slightly wilts.
  • Turn the heat off. Stir 4 oz of the cheese into the mixture.
  • Transfer the mixture to the prepared baking dish. Sprinkle the remaining 4 oz of cheese on top.
  • Bake until hot and bubbly, 10-15 minutes. If your baking dish is broiler-safe, you can broil the casserole instead of baking. Broil 6 inches below the heating element (not directly under), 2-3 minutes, or until the cheese has melted.



Instead of cooking on the stovetop then transferring the mixture to a baking dish, you can use a stovetop-and-oven-safe Dutch oven for both the stovetop cooking and the baking.
