Step 1: Prepare the Baking Dish
Preheat your oven to 350°F (175°C).
Melt 1 tablespoon of butter and brush the bottom and sides of a 9×13-inch baking dish with half of the melted butter. Reserve the remaining butter for later.
Step 2: Make the Scrambled Eggs
In a large mixing bowl, whisk together the eggs until the yolks and whites are fully combined and slightly frothy.
Whisk in the milk and kosher salt.
Heat the remaining tablespoon of butter in a large non-stick skillet over medium-low heat.
Pour in the egg mixture and cook slowly, gently stirring with a rubber spatula until the eggs are softly scrambled and just set. Remove from the heat before they become dry.
Step 3: Assemble the Sliders
Arrange the bottom halves of the slider buns in the prepared baking dish.
Sprinkle half of the shredded cheddar cheese evenly over the buns.
Spread the scrambled eggs over the cheese in an even layer.
Top with the crumbled bacon.
Sprinkle the remaining cheddar cheese evenly over the bacon.
Place the top halves of the buns over the filling.
Brush the tops of the buns with the reserved melted butter.
Sprinkle with garlic powder and flaky salt.
Step 4: Bake
Bake the Breakfast Sliders for about 15 minutes, or until the cheese is completely melted and the tops of the buns are lightly golden.
Allow the sliders to cool for about 5 minutes before serving.
Garnish with chopped fresh parsley if desired.
