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.
