Roll pizza dough into a 15-16” round circle. Place dough on a piece of parchment paper.
In a small dish, combine the olive oil, 2 tsp Italian seasonings, salt and garlic powder. Brush this mixture around the outer 1” of the dough. (This will become the crust for the pizza.)
Using a small bowl, mix together ricotta cheese, remaining 1 tsp Italian seasonings and minced garlic. Using an offset spatula, spread the ricotta mixture evenly on top of pizza dough.
Sprinkle mozzarella cheese evenly on top of ricotta.
Place thawed spinach in a colander and press firmly to drain as much liquid as possible. Sprinkle spinach evenly on top of cheeses. (Note: Adjust amount of spinach to your personal preferences. We used ~½ of a 10-oz. package on this version.)
Finally, spread red onions and grated Parmesan on top of the pizza.
Bake at 460°F for 12-13 minutes, or until pizza crust is golden brown in color.
Notes
For a spicy kick, a pinch of red pepper flakes on this pizza is pretty delicious!
