Press pizza crust out on a large pizza pan that has been coated with cooking spray. Melt butter in microwave and stir in garlic cloves. Spread this mixture over top of pizza crust. Layer as follows:
Mozzarella cheese, cubed potatoes, steak pieces, red onion.
Bake in 425 oven for 20 minutes or until crust is golden and cheese begins to turn brown.
Remove from oven and immediately sprinkle with blue cheese crumbles. Cut and serve.
Tip for If you are cooking your steak specifically for this recipe: I like to pan sear my steaks in butter, then put in the oven to finish off with crushed garlic and thyme sprigs. For this recipe I took the butter drippings and chopped the roasted garlic and put on the crust of the pizza before putting the cheese on.
