Cook the Bacon: Cook bacon until crispy. Chop into pieces and set aside.
Scramble the Eggs: Crack eggs into a bowl, season with salt and pepper, and whisk until combined. Cook in a nonstick skillet over medium-low heat, stirring gently, until just set and still slightly wet. Pull off the heat underdone — they finish in the oven.
Prep the Dish: Preheat oven to 350°F. Lightly grease a baking dish.
Build the Sliders: Slice buns in half horizontally and place the bottom halves in the baking dish. Spread scrambled eggs evenly over the buns. Scatter bacon on top, then sprinkle with shredded mozzarella. Add the top buns.
Make the Garlic Herb Butter: Stir together melted butter, minced garlic, Italian seasoning, parsley, and salt until combined. Brush generously over the tops of the buns.
Bake: Cover loosely with foil and bake 12 to 15 minutes until cheese is fully melted. Uncover and bake another 5 to 7 minutes until the tops are golden.
Serve: Serve hot, sliced into individual sliders or pulled apart at the table.
Notes
On the Buns: Hawaiian rolls are the standard for this format and work perfectly — their slight sweetness plays well against the savory garlic butter and salty bacon. Any soft slider bun works. Brioche slider buns are a good upgrade if you want something richer. Avoid anything crusty or hearty — you want a bun that soaks up the garlic butter, not one that resists it.
On Making Ahead: These are genuinely make-ahead friendly. Build the sliders completely, brush with the garlic butter, cover tightly with foil, and refrigerate overnight. Bake from cold the next morning — add about 5 minutes to the covered baking time. This is the move for brunch when you want to actually be present rather than cooking while everyone else eats.
On Scaling Up: The recipe makes 12 sliders, which serves 4 to 6 people generously. For a bigger crowd, build two baking dishes side by side. Everything scales directly — double the eggs, bacon, cheese, and butter. The bake time stays the same.
