In a skillet, cook the ground beef until browned. Drain excess fat.
In a mixing bowl, combine the cooked beef, heavy cream, 1 cup of shredded cheddar cheese, mashed cauliflower, garlic powder, onion powder, salt, and pepper.
Transfer the mixture to a baking dish and top with the remaining 1 cup of shredded cheddar cheese.
Bake in the preheated oven for 30-35 minutes, or until the cheese is bubbly and golden brown.
Let it cool for a few minutes before serving. Enjoy!
