Step-by-Step Cooking Instructions
-
Cook the Sausage: In a large skillet over medium heat, crumble and cook the breakfast sausage until browned. You’ll notice that delightful sizzle; drain off any excess grease and set aside.
-
Whisk the Eggs: In a medium bowl, whisk together the eggs, milk, garlic powder, salt, and pepper until well combined. This step is essential for a fluffy consistency.
-
Combine Ingredients: In a large mixing bowl, add the bread cubes and the cooked sausage. Pour the egg mixture over the bread and sausage, making sure everything is well-coated. This is when your kitchen starts smelling amazing!
-
Add Cheese: Gently fold in 1 cup of shredded cheese into the mixture—reserve the remaining cheese for topping.
-
Transfer to Casserole Dish: Grease a 9×13-inch casserole dish, then pour the mixture into the dish, spreading it evenly.
-
Top with Cheese: Sprinkle the remaining cheese on top, then cover the casserole with aluminum foil or plastic wrap.
-
Chill Overnight: Place the casserole in the refrigerator and let it rest overnight—it’s like letting the flavors get to know each other!
-
Bake: The next morning, preheat your oven to 350°F (175°C). Bake the covered casserole for 30 minutes, then uncover and bake for an additional 15–20 minutes, or until the top is golden brown and the casserole is set.
-
Serve Warm: Let it cool for a few minutes before slicing. Your home is about to be filled with the happiest of breakfast sounds!
Tips and Variations
- Vegetarian Option: Substitute sausage with sautéed veggies or plant-based sausage.
- Spice it Up: Add jalapeños or pepper jack cheese for a kick.
- Herb Infused: Fresh thyme or rosemary can add wonderful earthiness.
Serving Ideas
This casserole shines bright on its own but consider serving it with:
- Fresh fruit for a refreshing contrast.

- Mimosas or fresh-brewed coffee for a delightful brunch vibe.
Picture this: waking up to the sound of laughter as you share slices of this warm, cheesy indulgent treat, with each bite igniting memories of shared moments and hearty conversations.
Storage and Reheating
If you have any leftovers (which is rare!), store them in an airtight container in the fridge for up to 3 days. You can also freeze portions wrapped tightly for up to a month. When you’re ready to enjoy again, simply reheat in the oven at 350°F (175°C) until warmed through, or pop individual servings in the microwave for quick convenience.

- Add Fresh Herbs Last: If you’re using herbs, add them right before serving for a pop of freshness.
- Experiment with Cheese: Mixing cheeses like pepper jack, mozzarella, or feta can create delightful flavor profiles.
