Ingredients

Scale
  • 1 pound penne pasta

  • 1 pound lean ground beef

  • 2 tablespoons dried minced onion (or ½ cup fresh chopped yellow onion)

  • ½ tablespoon minced garlic

  • 1 teaspoon Italian seasoning

  • 32 ounces pizza sauce or marinara sauce (Contadina recommended)

  • 2 cups shredded mozzarella cheese

  • 16 slices pepperoni

  • 1 small green bell pepper, seeded and sliced

  • 1 can (4 ounces) sliced black olives

Optional: Add other favorite toppings like mushrooms, sausage, or red pepper flakes.

Instructions

  • Preheat and Prep the Dish
    Preheat your oven to 350°F (175°C). Lightly spray a 9×13-inch baking dish with non-stick spray and set aside.

  • Cook the Pasta
    Boil the penne pasta according to the package directions until al dente. Drain and set aside.

  • Brown the Beef
    In a large pot, cook the ground beef over medium heat until no longer pink. Drain any excess fat.

  • Build the Sauce
    Add the onion, garlic, Italian seasoning, and pizza sauce to the beef. Stir well to combine, then remove from heat.

  • Mix with Pasta
    Add the cooked pasta to the meat sauce mixture and stir until everything is well coated.

  • Assemble the Casserole
    Transfer the mixture into the prepared baking dish. Top evenly with shredded mozzarella, pepperoni slices, bell pepper, and olives.

  • Bake the Casserole
    Cover the dish with aluminum foil and bake for 25 minutes, or until the cheese is melted and bubbly.

  • Cool and Serve
    Let the casserole sit for about 5 minutes before slicing and serving.

Notes

  • Swap in turkey or chicken for a lighter version.

  • Use whole wheat or gluten-free pasta for dietary preferences.

  • Add more veggies like mushrooms, red onions, or spinach for a veggie-loaded variation.

  • Great for meal prep—store leftovers in the fridge for up to 4 days or freeze for up to 2 months.
