Preheat the oven to 400°F (200°C). Place the frozen pizza slice on a baking sheet lined with parchment paper.
Cook the burger patty in a skillet over medium heat until browned and cooked through, about 4-5 minutes per side. Remove from heat and set aside.

Bake in the preheated oven for 10-12 minutes, or until the cheese on the pizza is melted and bubbly, and the crust edges are golden brown.
Remove from the oven and let it rest for 2 minutes. Carefully transfer the pizza burger to a plate using a spatula.
Slice in half if desired, and serve immediately to enjoy the crispy crust and melted cheese with tender beef.
