Preheat your oven to 375°F (190°C). Gather your baking dish and utensils.

Boil salted water and cook the chickpea pasta according to package instructions for 7-9 minutes. Drain and set aside.

In a large skillet over medium heat, brown the ground beef for 5-7 minutes. Drain excess fat and set aside.

In a large mixing bowl, combine the cooked pasta, browned beef, mozzarella, cottage cheese, marinara sauce, and egg, mixing gently.

Spread a thin layer of marinara sauce on the bottom of a 9x13 casserole dish.

Spoon the pasta mixture over the marinara sauce in the baking dish, spreading it evenly.

Bake in the oven for 25 minutes until the cheese is melted and golden brown. Optionally broil for 2-3 minutes for a crispy top.

Let the baked ziti cool for 5-10 minutes before serving.
