This Deep Dish Skillet Pizza Casserole is a thick crust, Chicago-style pan pizza that is easy to make and is absolutely loaded with tangy pizza sauce and all your favorite pizza toppings.
Use a fork to mix together the crust's dry ingredients. Add the warm water and and olive oil. Use a mixer and kneading arm to mix the ingredients until a soft dough ball is formed. Transfer the soft dough ball into a well-oiled metal or glass bowl and cover with a dish towel for about 45 minutes.
While dough is rising, preheat oven to 425℉, brown sausage, grate cheese and make sauce.
Sauce:
In a medium sauce pan over medium low heat, add all of the sauce ingredients and stir to combine until the sauce is warm and bubbly. Add sauce to browned sausage and mix together. Set aside.
Pizza:
Add 1-2 tablespoons of olive oil to a 10-12 inch cast iron skillet. Use a paper towel to oil the bottom and sides of the skillet. Dust the bottom and up the side of the skillet with cornmeal. Add a little garlic powder and dried parsley for extra flavor, if desired.
Lightly dust the dough ball with flour. Remove from the bowl and place dough ball in the center of the skillet. Use your fingers to gently push the dough out towards the edges and half way up the sides of the skillet.
Layer:-½ of the grated mozzarella in the bottom of the crust.-½ of the meat & sauce mixture.-15-20 pepperoni slices-½ of the remaining mozzarella-all of the remaining meat mixture-15-20 pepperoni slices-remaining mozzarella cheese + the parmesanThe pizza filling should completely fill the crust to the top its edge.
Bake uncovered in preheated oven on the bottom rack for 30-35 minutes. Check pizza around 20 minutes, if crust edges are getting too brown, cover with foil and continue to bake. Remove from oven. Allow to stand for 5-10 minutes before slicing.
Notes
If your dough is too sticky to make a soft ball, then add ¼ cup of flour a little at a time until the texture is pillow-like. Adding too much flour will make the dough stiff.
Dusting the skillet with cornmeal adds texture and flavor to the crust. It also helps to keep the dough from sticking to the pan.
I always sprinkle a little bit of garlic salt and dried parsley in the bottom of the skillet along with the cornmeal for a more flavorful pizza crust.
