How to Make Zucchini Pizza Casserole
Preheat Your Oven: Begin by preheating your oven to 375°F (190°C). Greasing a baking dish will ensure nothing sticks as it bakes.
Prepare the Zucchini: Slice your zucchinis into thin rounds while ensuring they are uniform in size. Sprinkle them lightly with salt and let them sit to draw out excess moisture.
Layer the Ingredients: Start layering by placing half of your zucchini slices at the bottom of the greased dish. Follow up with half of your marinara sauce, pepperoni slices, and mozzarella cheese.
Add More Layers: Repeat the layering process with the remaining zucchini, sauce, pepperoni, and finally top off with mozzarella and Parmesan cheese for that golden crust.
Bake Until Golden Brown: Place your casserole in the preheated oven and bake for about 30-35 minutes until bubbly and golden brown. The smell will be irresistible!
Let It Rest Before Serving: Once baked, allow it to cool for about 10 minutes before slicing—it helps everything set nicely and makes serving easier.
This Zucchini Pizza Casserole is not only delicious but also an excellent way to sneak in some veggies without anyone noticing! Each layer offers a new dimension of flavor while keeping dinner fun and exciting. Enjoy every bite!
