1-Start: Start by preheating your oven to 400 degrees Fahrenheit, which is perfect for baking the pie to golden perfection.

2-Prepare Pie Crust and Meat: First, prepare your unbaked 9-inch pie crust by chilling it ahead of time. This helps create a sturdy base for the filling. Once ready, brown the 1/2 pound ground beef with 1 medium finely chopped onion and 2 cloves minced garlic in a pan, then drain the fat for a cleaner mixture.

3-Mix Filling: Next, stir in 3 tablespoons all-purpose flour, 1 teaspoon salt, and 1/2 teaspoon black pepper to the beef mix. Spread this evenly into the pie shell for an even base. Then, top it with 1 cup grated cheddar cheese and 1 1/2 cups shredded mozzarella cheese to add that rich, melty layer.

4-Prepare Binding Mixture: In a separate bowl, whisk together 1 cup milk, 2 eggs, and 1 tablespoon Worcestershire sauce until smooth. Pour this over the meat and cheese layers carefully. This mixture binds everything together for a creamy finish.

5-Bake the Pie: Bake the pie in your preheated oven for 35 to 40 minutes until it’s bubbly and the crust is golden. Keep an eye on it to avoid overcooking, and remember the total time is about 50 minutes. Once done, let it cool a bit before slicing for the best results.
