Tried this on a whim a few weeks back and it was a little tricky to roll since I sliced the zucchini by hand, but delicious nonetheless! Will try slicing more thinly with the spiralizer next time.
2 cups cottage cheese, small curd or whipped
2 large eggs
1/2 cup freshly grated Parmesan, divided
1 tsp. garlic powder
Freshly ground black pepper
1 cup marinara sauce
2-3 zucchini, sliced 1/8″ thick
1 cup grated mozzarella
Preheat oven to 400°. Gently beat cottage cheese and eggs to mix; with 1/4 cup Parmesan and garlic powder. Season to taste with salt and pepper. Spread a thin layer of tomato sauce onto the bottom of a 9″-x-13” baking dish. Separately (e.g., on cutting board or plate), lay out the zucchini slices and spoon a thin layer of sauce on each, then top with a thicker layer of cheese mixture and sprinkle with mozzarella. Roll up and place in baking dish, securing with a toothpick if needed. Sprinkle with remaining 1/4 cup Parmesan and bake until zucchini is tender and cheese is melted, about 30 minutes.
