Turn your oven on and heat it up to 350°F. Rub butter or spray with nonstick oil all over a 9x13-inch pan so the food won't stick when serving.

Spread the frozen tots out evenly across the bottom of your greased dish to form a solid crispy foundation.
03 -
Grab a big bowl and whisk the eggs, milk, salt, pepper, and mustard (if you're including it) until it's all smooth and uniformly blended together.

Crumble the cooked bacon and scatter it evenly over the tater tots. Then sprinkle both types of cheese on top for a melty, cheesy layer.
05 -
Carefully pour the egg mixture across the dish, slowly enough to let it seep in around the layers evenly.
06 -
Sprinkle the chopped green onions over the dish if you'd like. Bake for 40-45 minutes, uncovered, until the eggs are fully cooked and the surface is golden and slightly crisp.

Take it out of the oven and let it cool for 5-10 minutes before slicing. This makes cutting and serving way simpler.
