Breakfast Casserole with Bacon, Potatoes and Eggs
This breakfast casserole uses small pre-cooked potato pieces rather than relying on raw potatoes to soften inside the eggs.
This breakfast casserole uses small pre-cooked potato pieces rather than relying on raw potatoes to soften inside the eggs. Bacon, onion and pepper are cooked first, then the egg mixture sets around them in the oven. Cheddar browns across the surface, and a brief rest makes the bake easier to cut. The filling should be tender throughout with no wet egg pocket in the middle. It suits a shared breakfast or brunch when individual frying would take longer.
