- 3 cups milk: Whole milk adds richness; however, low-fat or almond milk can be used for a lighter option.
- 1 teaspoon fine sea salt: Enhances flavors; adjust to your preference.
- ½ teaspoon black pepper: Just the right amount for a little kick; feel free to add more for spice lovers.
- 6 cups cubed bread: Use day-old bread for optimal texture; sourdough or French bread works wonderfully.
- 2 cups shredded sharp cheddar cheese: For that ooey-gooey delight; try pepper jack cheese for an extra punch.

- Sliced green onion (optional): Great for garnish, offering a fresh, slightly peppery finish.
How to Make Breakfast Casserole | Easy Make-Ahead Father’s Day Brunch Bake
- Prepare the Casserole Dish: Grease a 9x13x2-inch casserole dish with cooking spray or butter to ensure easy removal.
- Cook the Sausage: In a large skillet over medium-high heat, cook 1 pound of pork sausage, breaking it apart with a spatula, until fully cooked and no longer pink.
- Mix the Egg Mixture: In a large bowl, whisk together 10 large eggs, 3 cups of milk, 1 teaspoon of fine sea salt, and ½ teaspoon of black pepper until thoroughly combined.
- Layer the Ingredients: Evenly distribute half of the cubed bread (about 3 cups) into the prepared casserole dish. Sprinkle with half of the shredded sharp cheddar cheese, half of the black pepper, half of the diced red pepper (if using), and half of the cooked sausage. Repeat the layering with the remaining ingredients.
- Add the Egg Mixture: Pour the egg mixture evenly over the layered casserole, ensuring it saturates the bread.
- Refrigerate or Bake: Cover and refrigerate overnight if desired, or you can bake it immediately.
- Bake the Casserole: Preheat the oven to 325°F. Bake uncovered for 60-75 minutes, or until the eggs are set and the top is golden. If the top starts browning too quickly, loosely cover with foil during baking.
- Serve Warm: Once out of the oven, sprinkle with sliced green onions, if using. Slice and serve warm for the best experience.
Storing & Reheating
To store leftovers, let the casserole cool completely before placing it in an airtight container in the fridge, where it will keep for about 3-4 days. If you want to freeze any portions, wrap them tightly in plastic wrap or aluminum foil, then place in a freezer-safe bag or container for up to 3 months. Reheat in the oven at 350°F for about 20-30 minutes, or until heated through. The texture might change slightly—but a sprinkle of fresh herbs or a drizzle of hot sauce can refresh it beautifully.
Chef’s Helpful Tips
- Avoid overcooking the sausage; it should be browned but not too crispy, preserving its juiciness.
- Use room temperature eggs for better mixing; they incorporate more air for a fluffier casserole.
- Timing is key; allow enough time for the dish to set in the refrigerator, ideally overnight.
- If your casserole feels a bit too dry, serve it with salsa or a dollop of sour cream for extra richness.
- Experiment with different cheeses or proteins like bacon or ham to customize the dish to your family’s taste.
Embracing comfort food like this breakfast casserole doesn’t just fill the belly; it fills hearts and creates memories. From family gatherings to hearty holiday brunches, every slice is a reminder of love and togetherness. I encourage you to try this recipe, perhaps even adding your own twist, and see how it becomes a beloved staple in your home. Enjoy each moment spent with your loved ones, sharing warmth and flavor over this delightful dish.

Recipe FAQs
Can I make this casserole vegetarian?
Absolutely! You can substitute the pork sausage with plant-based sausage alternatives or simply omit it altogether. Adding in more vegetables like mushrooms, zucchini, or spinach can enhance the flavor and texture.
How do I ensure my casserole isn’t soggy?
Using day-old bread is key in preventing sogginess, as it absorbs the egg mixture without becoming mushy. Just make sure you allow the casserole enough time for the bread to soak up the liquid ingredients before baking.
Can I add different cheeses?
Certainly! Feel free to switch up the cheese to your favorite varieties. Gruyère, mozzarella, and even feta can offer delightful flavor combinations. Just ensure you have about 2 cups of cheese in total for the best consistency.
Is it possible to bake this casserole if I forgot to prepare it the night before?
Yes, you can still bake it right after assembling. However, the texture may be slightly less fluffy, as it won’t be as saturated with the egg mixture. Just bake a little longer to ensure the center is fully cooked.
