Step 5: Sprinkle the Cheese
- Top the sauce with shredded mozzarella cheese, ensuring an even layer for that melty goodness.
Step 6: Add Toppings
- Scatter pepperoni slices (or your choice of toppings) over the cheese. Don’t be shy—load them up!
Step 7: Season
- Sprinkle Italian seasoning over the top for an extra flavor boost.
Step 8: Bake
- Place the prepared portobello pizzas on a baking sheet and bake in the preheated oven for 15-20 minutes, or until the cheese is bubbly and golden.
