Part 2/4:
Begin the cooking process by melting the butter in a saucepan over medium heat. Allow the butter to melt until it achieves a golden brown color, which infuses the dish with a rich flavor.
In a separate bowl, mix the diced potatoes, chopped onion, and bacon. This combination creates a wonderful base for the casserole. Next, sprinkle the flour over the mixture and combine well to ensure the potatoes and bacon are evenly coated.
In another bowl, beat the eggs and then whisk in the milk. This egg and milk mixture serves as the binding agent for the casserole, holding all the components together while adding moisture.
