Preheat the oven to 350 degrees F (175 degrees C).

Melt 2 tablespoons butter in a large saucepan over medium-low heat. Add broccoli, onion, and garlic; cook, stirring occasionally, until vegetables are soft. Spoon vegetables into pie crust and sprinkle with mozzarella cheese; set quiche on a baking sheet.

Step 3
Combine eggs and milk together in a bowl; season with salt and pepper. Stir in remaining 1 tablespoon melted butter; pour egg mixture over vegetables.

Step 4
Bake in preheated oven until the center of the quiche has set, about 30 to 50 minutes.
