Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish.
Layer the Tater Tots:
Arrange the frozen tater tots in a single layer at the bottom of the prepared baking dish.
Mix the Egg Mixture:
In a large bowl, whisk together the eggs, milk, ranch dressing mix, salt, and pepper until well combined.
Add the Meats and Cheeses:
Stir in the crumbled bacon (or cooked sausage/ham) and shredded cheddar cheese into the egg mixture. Pour this mixture evenly over the tater tots in the baking dish. Dot the top with cubes of cream cheese.
Bake:
Place the baking dish in the preheated oven and bake for 45-50 minutes, or until the eggs are set and the top is golden brown.
Garnish and Serve:
Let the casserole cool for a few minutes before slicing. Garnish with chopped green onions before serving.
