1.
In a mixing bowl combine the yeast, brown sugar, and water. Allow to stand until foamy and creamy about 5 to 10 minutes.
2.
Fit the dough hook to a stand mixer. Turn mixer on to the lowest setting and slowly add half of the flour 1/2 cup at a time. Once half of the flour has been added, add in the garlic salt and the softened butter. Continue adding in the remaining flour and mix until the dough has climbed up around the dough hook. If the dough seems too sticky add in 2 tablespoons flour. If the dough seems too dry add in 2 tablespoons water.
3.
Using a pastry brush, coat the inside of a large glass bowl with 1 tablespoon of the grapeseed oil. Place the dough into the bowl, turning to coat all sides. Take a piece of plastic wrap and lightly spray with cooking spray, place on top of the bowl, giving a small area for ventilation. Place in a warm area, cover with a towel and wait until doubled in size, about 45 minutes.
4.
Once dough has doubled, punch dough down, and allow to rest 20 minutes.
5.
Preheat oven to 400 degrees F.
6.
Coat the inside of the cast iron skillet with the remaining 2 tablespoons grapeseed oil. Press dough into the bottom and up the sides of the skillet. Using a fork lightly poke holes onto the bottom of the crust to prevent air bubbles. Spread pizza sauce around the base of the crust.
7.
Sprinkle about 1/2 cup of the cheese on top of the pizza sauce. Add half of pepperoni to the pizza, half of the pork sausage and add half of the Italian sausage. Repeat this step one more time until all toppings are added, Sprinkle remaining cheese onto the pizza.
8.
Bake on the bottom rack for 25 minutes or until golden brown. Remove pizza from skillet, and let rest for 3 minutes before slicing.
Serving suggestion
Pair this with a chicken ceasar salad for a winning combination.
Tip
This dough can be made ahead and proofed overnight in the refrigerator. Additionally it can be divided into smaller portions if you prefer a thin crust pizza.
Tip
Don't have a pizza stone but you prefer a personal size thin crust pizza? Problem solved. Flip a cast iron skillet over (preferrably one w/ a flat/smooth surface) and slide your pizza onto the bottom side of the skillet and bake as you would using a pizza stone!
