• ½ cup diced onion

• ¼ cup panko breadcrumbs mixed with 1 tbsp melted butter (for topping)

All the components you’ll need to build a perfect breakfast casserole.

Step‑by‑Step Instructions

1. Preheat the oven to 375 °F (190 °C). Lightly grease a 9×13‑inch baking dish with butter or non‑stick spray.
2. Cook the bacon in a skillet over medium heat until crisp. Transfer to a paper‑towel‑lined plate, crumble, and set aside.
3. Sauté aromatics: In the same skillet, add diced onion and cook until translucent, about 3‑4 minutes. Add garlic powder, smoked paprika, salt, and pepper; stir for 30 seconds.
4. Combine wet ingredients: In a large mixing bowl, whisk together eggs, milk, and a pinch of salt and pepper until fully blended.
5. Assemble the base: Spread the cubed rolls evenly in the prepared baking dish. Sprinkle the sautéed onions, crumbled bacon, and chopped chives over the bread cubes.
6. Pour the custard: Slowly pour the egg‑milk mixture over the bread cubes, ensuring the liquid reaches all corners. Press gently with a spatula so the cubes absorb the custard.
7. Add cheese: Sprinkle shredded cheddar evenly across the top, allowing it to melt into the casserole as it bakes.
8. Prepare the topping: Toss panko breadcrumbs with melted butter; sprinkle the mixture over the cheese for a golden, crunchy crust.
9. Bake uncovered for 30‑35 minutes, or until the center is set, the edges are lightly browned, and the breadcrumb topping is crisp and golden.
10. Rest before serving: Allow the casserole to rest for 10 minutes. This helps the custard firm up, making it easier to cut clean squares.
11. Slice and serve: Use a sharp knife to cut into 2‑inch squares. Garnish with extra chives if desired and serve hot.
12. Enjoy! Pair with fresh fruit, a light salad, or a hot cup of coffee for a complete breakfast experience.

Pro Tips & Tricks

• Make it ahead: Assemble the casserole up to step 7, cover tightly with foil, and refrigerate overnight. Add the breadcrumb topping and bake fresh in the morning.
• Upgrade the cheese: Mix cheddar with pepper jack or Gruyère for extra depth.
• Even soaking: Toss the bread cubes with a little melted butter before layering; this helps them stay moist and flavorful.
• Crunch factor: For an extra crunch, add 2 tbsp finely chopped toasted nuts (like pecans) to the breadcrumb topping.
• Portion control: Use a 12‑cup muffin tin to create individual breakfast slider “cups” that are perfect for grab‑and‑go.

Variations & Substitutions

Storage Tips

Allow the casserole to cool completely before refrigerating. Store in an airtight container for up to 4 days. To reheat, cover with foil and bake at 350 °F (175 °C) for 15‑20 minutes, or microwave individual portions for 1‑2 minutes.

For longer storage, freeze up to 2 months. Wrap tightly in plastic wrap, then foil. Thaw overnight in the fridge and reheat as above.
