Preheat oven to 175°C. Generously grease a 23x33-centimetre baking dish with butter or nonstick spray to prevent sticking.
02 -
Distribute the frozen tater tots evenly in a single layer across the base of the prepared baking dish for a crisp foundation.
03 -
In a large mixing bowl, whisk together eggs, whole milk, salt, black pepper, and dry mustard powder if using. Mix until no egg white streaks remain.
04 -
Sprinkle the cooked, crumbled bacon evenly over the tater tots. Top with both shredded cheddar and Monterey Jack or pepper jack cheeses for enhanced flavour.
05 -
Carefully pour the whisked egg mixture evenly over the layers, ensuring the liquid seeps between the tater tots and cheese.
06 -
Optionally, scatter chopped green onions over the top. Bake uncovered for 40–45 minutes until eggs are fully set and the surface is golden brown.
07 -
Remove from the oven and let rest 5–10 minutes to set before cutting and serving.
