- Margherita style use fresh sliced tomatoes instead of pepperoni and stir in torn fresh mozzarella after baking for a lighter, fresher flavor.
- Spicy pepperoni add a half teaspoon of red pepper flakes to the sauce and use spicy Italian sausage for more heat and depth.
- Gluten free use gluten free pasta and check that your marinara is GF for a friendly swap that keeps all the same bake time.
