How To Make Pizza Casserole With Cauliflower
The first step is to chop your cauliflower into small florets. Now bring a pot of water to a boil and cook cauliflower until it’s softened. You can also steam it in the microwave if that’s your prefered method. Drain and add cauliflower into a 11×8 casserole dish.
Mix the butter and minced garlic in a small bowl. Pour the butter mixture over the cauliflower. This mixture smells like the garlic sauce that some restaurants put on pizza crust, yum!
Chop up 15 slices of pepperoni. You can use a knife, cutting shears, or just rip them up with your hands. Add into the casserole dish.
Add a little bit of shredded mozzarella and pizza sauce into the casserole dish on top of the cauliflower, giving it a stir.
Sprinkle the remaining 1 cup of shredded mozzarella on top of the casserole.
And then add the remaining slices of pepperoni on top.
Now it goes into the oven to bake until bubbly. When it comes out of the oven, garnish it with fresh basil or oregano. Dinner is served!
Storing Leftovers
Store any leftover cauliflower pizza casserole in an airtight container in the refrigerator for up to 4 days. To reheat, simply pop it in the microwave or warm it in the oven until heated through. It’s just as delicious the next day—perfect for easy lunches or a quick dinner!
