In a large skillet over medium heat, cook 2 pounds of ground beef until browned. Drain off the grease and set aside.
In a large bowl, stir together the drained cottage cheese, chunky salsa, taco seasoning, and ¾ cup of the shredded cheese. Add the cooked ground beef and stir until everything is well combined.
Transfer the mixture to a shallow baking dish or cast iron skillet. Smooth the top and sprinkle on the remaining ¾ cup of cheese.
Bake at 375°F for about 20 minutes, or until the cheese is melted and bubbly. Serve hot with your favorite toppings like sour cream, avocado, or green onions.
