Preheat the oven at 375.
First, in a large bowl mix ricotta cheese, Parmesan, red pepper flakes, parsley, oregano, basil, garlic, and salt/pepper.
Next, add the ground beef, eggs, and bread crumbs to the bowl. Mix to combine all the ingredients well.
Now, form the meat mixture into a ball and place on a parchment paper (or tinfoil) lined sheet pan.
Push and shape ball of meat into a pizza crust shape. Approximately the size of a dinner plate.
Next, place in the oven for 25 minutes to cook the meatloaf pizza crust.
When the meatloaf comes out of the oven, drain excess grease from sheet tray. (Be Careful: use spoon to hold the meatloaf so it does not fall off sheet tray).
Now, add the marinara sauce on top, then the cheese, and finally the pepperoni (or your favorite toppings).
Finally, place back in the oven 10-15 minutes. It is ready when cheese melt and bubbly.
