In a skillet, cook the ground meat over medium heat until browned. Drain any excess grease.
In a large bowl, mix together the hash browns, drained Rotel, cheese soup, taco seasoning, and 1 ½ cups of shredded cheese.
Add the cooked meat to the mixture and stir well to combine.
Lightly grease the slow cooker and spread the mixture evenly inside.
Cover and cook on low for 4-5 hours or high for 2-3 hours, until everything is heated through and the flavors meld together.
In the last 20 minutes, sprinkle the remaining ½ cup of shredded cheese on top and let it melt.
Once done, serve hot with tortillas, fresh salad, or your favorite toppings.
Enjoy your cheesy, comforting taco casserole!
