Preheat your oven to 350°F (175°C) and grease an 8x8-inch casserole dish with cooking spray or butter.
In a large skillet over medium heat, cook the ground beef and diced onion until the beef is browned and the onion is soft, about 5-7 minutes. Drain any excess grease.
Stir garlic powder, onion powder, salt, and black pepper into the beef mixture. Remove the skillet from heat and let it cool slightly.
Add the softened cream cheese to the beef mixture and stir until fully combined.
In a medium mixing bowl, whisk together eggs, heavy cream, and almond flour to make the casserole's 'bun-like' topping. Set aside.
Spread the beef mixture evenly into the prepared casserole dish.
Sprinkle 1 cup of shredded cheddar cheese over the beef layer.
Pour the egg and almond flour mixture evenly over the casserole and gently spread it with a spatula to cover the beef layer.
Top with the remaining 1 cup of shredded cheddar cheese.
Bake in the preheated oven for 20-25 minutes, or until the top is golden brown and the center is set.
Remove the casserole from the oven and let it cool for 5-10 minutes before serving.
Optionally, garnish with diced dill pickles for an extra touch of that classic burger flavor.
