  • 25-30 jumbo shells, cooked al dente
  • 1 pound (453.6g) lean ground beef
  • 1 small yellow onion, diced
  • 1 small green bell pepper, seeded and diced
  • 8 ounces (226.8g) brown mushrooms, minced
  • 2 tablespoons (34g) ketchup
  • 1 tablespoon (17g) Worcestershire sauce
  • 2 teaspoons (3g) Kosher salt
  • 1/2 teaspoon fresh ground black pepper
  • 1 tablespoon cornstarch, for slurry
  • 1 cup (240g) beef broth, for slurry
  • 1 cup Provolone cheese, shredded
  • 2 tablespoons scallion, diced (optional)


  1. Preheat oven to 350°F.

  2. In a cast-iron skillet over medium-high heat, cook the beef until no longer pink, breaking up large crumbles with the back of a wooden spoon. Use a slotted spoon to transfer the beef to a paper towel-lined plate.

  3. Reduce the heat to medium.
  4. To the fat still in the skillet, add the onion, bell pepper, and mushroom. Cook until softened. Stir the beef back in with the vegetables.
  5. Stir in the ketchup, Worcestershire sauce, salt, and pepper. Let cook while preparing the slurry. Prepare the slurry by stirring the cornstarch with the broth in a small bowl until smooth. Pour into the skillet and mix to combine. Allow the mixture to boil until most of the liquid evaporates.

  6. Stuff mixture into the cooked shells and place in a greased 9x13-inch baking pan.

  7. Top with shredded provolone cheese.

  8. Bake 15-20 minutes, or until bubbly.

  9. Top with scallions (optional).
