Layered Potato-Zucchini Pizza Bake with Sausage and Mozzarella

I was attempting to find a new way to make zucchini pizza crust, and ended up with a warm, layered bake that eats like comfort food and looks like a rustic slab pizza. Thin slices of potato and zucchini form a tender, structured base, melted Parmesan binds everything together, and savory Italian sausage adds richness. Mozzarella melts into a golden, bubbly top while grape tomatoes and basil bring brightness. It's hearty, colorful, and surprisingly simple—a cozy, veggie-forward pizza bake that feels like home.

Ingredients

Layered vegetables

• ¼ cup cornstarch
• ⅔ cup water
• 1 tsp salt + salt for zucchini
• ½ tsp pepper
• ½ tsp onion powder
• ½ tsp garlic powder
• 1 tsp oregano
• 2 lbs yellow potatoes (sliced ⅛")
• 1 lb zucchini (sliced ⅛")
• Olive oil (for brushing pan)

Toppings

• ½ cup grated Parmesan
• 1 lb Italian sausage
• 8 oz mozzarella
• ½ pint grape tomatoes (sliced in half lengthwise)
• ¼ cup basil (chiffonade)

Directions

1. Preheat oven to 400°F.
2. Brush a 14" pizza pan with olive oil; set aside.
3. Lay out zucchini slices and salt them. Let sit 10 minutes, then pat dry.
4. Mix cornstarch with salt, pepper, onion powder, garlic powder, and oregano.
5. Add ¼ cup of the cornstarch mix to the water to make a slurry.
6. Toss potato slices in the slurry.
7. Toss zucchini in the remaining dry cornstarch mix.
8. Build a layer of potato slices, then zucchini, then repeat.
9. Add one more layer of potato slices on top of the zucchini.
10. Press down vegetables in the pan.
11. Bake for 40 minutes.
12. While baking, brown sausage and prepare toppings.
13. When the crust comes out of the oven, the first topping will be the Parmesan—this helps hold it together.
14. Layer sausage, mozzarella, basil, and tomato.
15. Bake 20 minutes, rotating halfway through.

Notes

• I start by slicing and salting the zucchini first so I can let it set while I prep the rest.
• Make sure to top the potato-zucchini layer with Parmesan before the other ingredients.
• This is served best cut into squares.
