Use nonstick cooking spray or butter in your casserole dish.
Important note: We used 2 cans of the large biscuits but only put 1.5 cans in our mixture. Biscuits expand while cooking and when they're too think they have an issue
Open cans of refrigerated biscuit dough and cut each biscuit into 4-6 pieces and place into greased pan. You can also put them in a bowl and then put the mixed product in the casserole dish.
Mix 1 cup of pizza sauce of your choice to the cut biscuit pieces.
Add 1 cup of shredded mozzarella cheese to the pizza sauce and biscuit pieces and mix all together well.
If you want some toppings on the inside of this pizza you can add them now and mix well.
Take all of the mixture and flatten it lightly in the casserole dish.
Top with another 1 cup of shredded mozzarella cheese.
Add any toppings that you would like. We used pepperoni.
Sprinkle about 1 tsp of garlic salt and 2 tsp of Italian seasoning. Or whatever amount you like taste-wise.
Bake uncovered at 375 degrees for 25-30 minutes. Start checking the progress of baking at around 20 minutes. You use a knife or fork to peek at the middle of the casserole dish to check to see the doneness of the biscuits. It takes a bit to get them fully cooked. If the top starts getting too dark you can cover with foil for the remainder of the cooking time.
Once the biscuits are fully cooked at the center of the casserole you're ready to take it out and serve. I like to serve with a little container of additional sauce for dipping.
Enjoy! The meal will take a few minutes to cool off so be careful with serving little ones.
