Before you start

Before beginning, ensure all ingredients are measured and ready. Preheat the oven to 375°F (190°C) to ensure an even bake. Have a 9-inch pie dish lightly greased with butter or cooking spray to prevent sticking.

Ensure the ground beef is fully defrosted if using frozen, and keep the cheese cold until the moment of assembly to maintain the best quality.

Ingredients at a glance (4)
  • 1 lb ground beef
  • 1 cup tomato sauce
  • 1 1/2 cups shredded mozzarella cheese
  • 1/4 cup pepperoni slices

Instructions

Browning the meat

  1. Cook the meat filling
    Place the ground beef in a skillet over medium-high heat. Cook until thoroughly browned, stirring occasionally to break up large chunks. Drain any excess grease from the pan. Ensure the meat reaches a safe internal temperature of 160°F (71°C) before proceeding to the next step.
    Look for The beef is fully browned and no pink remains.

    Tip Season the beef with salt and pepper to taste while cooking.

The ground beef should be deeply browned and fragrant. Ensure all moisture has evaporated from the skillet to avoid adding excess liquid to the pie. The meat should be broken into small, uniform crumbles for the best texture throughout the final dish.

Assembling the layers

  1. Assemble the pie
    Spread the browned ground beef into the bottom of a greased 9-inch pie dish. Pour the tomato sauce over the beef, then sprinkle with the shredded mozzarella cheese. Arrange the pepperoni slices on the surface.
    Look for The layers are evenly distributed in the pie dish.
    Tip Ensure the beef is spread to the edges for even coverage.

The beef should be spread evenly in the dish. The sauce should be distributed to cover the meat, and the cheese should be sprinkled uniformly to ensure a cheesy top.

The pepperoni slices should be arranged on top to ensure they crisp up perfectly during the baking process.

Final bake

  1. Bake the pie
    Bake at 375°F (190°C) for 30-35 minutes until the crust is golden brown and bubbly. Let the pie rest for 5 minutes before slicing to allow the filling to set.
    Look for The crust is golden brown and the cheese is melted and bubbling.
    Tip Let the pie rest for 5 minutes before slicing to allow the filling to set.

The pie is ready when the surface is golden and the pepperoni is crispy. The center should be set and firm. The aroma of baked dough and savory meat should be prominent in the kitchen, signaling that the dish is perfectly cooked.

Common mistakes

A common mistake is failing to fully drain the cooked ground beef, which can lead to a soggy crust. Another error is overmixing the batter, which may result in a tough, chewy crust rather than a light and tender one.

Finally, ensure the oven is fully preheated before putting the pie inside; a cold oven will prevent the batter from rising correctly, leading to a flat, dense texture.

How to tell it’s done

The pie is done when the crust is golden brown and firm to the touch. A toothpick inserted into the center should come out clean, indicating the batter has fully set.

The cheese should be bubbling and slightly browned in spots. The internal temperature of the filling should be consistent, and the edges should pull away slightly from the sides of the dish.
