Ingredients You’ll Need
- 1 pound pork sausage: Choose a flavorful variety for a hearty base; turkey sausage is a lighter alternative.
- 10 large eggs: Lightly beaten, these provide the fluffy texture that holds it all together.
- 3 cups milk: Whole milk works best for richness, but feel free to substitute with 2% for a lighter option.
- 1 teaspoon fine sea salt: A necessary addition to enhance the overall flavor of the dish.
- ½ teaspoon black pepper: Adds a subtle warmth and depth.
- 6 cups cubed bread: Stale bread is preferable as it absorbs the egg mixture better; sourdough or French bread are delightful choices.
- 2 cups shredded sharp cheddar cheese: The star ingredient that lends a glorious gooey texture and appealing flavor.
- ½ cup diced red pepper (optional): Adds color and a slight crunch; green pepper or even spinach can work too.
- Sliced green onion (optional): A fresh garnish that elevates presentation and provides a burst of flavor atop the casserole.
How to Make Breakfast Casserole | Easy Make-Ahead Father’s Day Brunch Bake
- Prepare the Dish: Start by greasing a 9x13x2-inch casserole dish with cooking spray or butter to ensure easy serving later.
- Cook the Sausage: In a large skillet, cook the pork sausage over medium-high heat. Stir frequently until it’s thoroughly cooked and no longer pink, about 5-7 minutes. Drain any excess grease and set it aside.
- Whisk the Egg Mixture: In a large bowl, whisk together the 10 lightly beaten eggs, 3 cups of milk, 1 teaspoon fine sea salt, and ½ teaspoon black pepper until fully combined.
- Layer the Casserole: Evenly distribute half of the cubed bread into the prepared casserole dish. Sprinkle with half the shredded sharp cheddar cheese, half the cooked sausage, and half the diced red pepper, if using. Repeat these layering steps with the remaining ingredients.
- Add the Egg Mixture: Pour the egg mixture evenly over the layered casserole, ensuring it seeps through the bread.
- Refrigerate or Bake: Cover the dish with foil and refrigerate overnight to let the flavors meld. Alternatively, you can bake it immediately.
- Bake the Casserole: When you’re ready, preheat your oven to 325°F. Bake the casserole uncovered for 60-75 minutes. It’s ready when the eggs are set, and edges are lightly golden. If the top begins to brown too quickly, loosely cover the dish with foil.
- Garnish & Serve: Once baked, sprinkle with sliced green onions if desired and serve warm. Enjoy each slice!
Storing & Reheating
To store leftovers, cool the baked casserole to room temperature before placing it in a tightly sealed container in the refrigerator, where it can last for about 3-4 days. For longer storage, freeze the casserole by wrapping it well in plastic wrap and then foil, keeping it fresh for up to 3 months. When you want to enjoy it again, simply reheat in the oven at 350°F for about 20-25 minutes or microwave individual portions. The texture may vary slightly, but a sprinkle of cheese on top before reheating can bring back some of that gooey goodness.
Chef’s Helpful Tips
- Avoid sogginess by using slightly stale bread; let fresh bread sit out for a few hours before cubing it.
- Always let the casserole rest for a few minutes before serving to help it set and make slicing easier.
- Don’t skip on seasoning; adjust the salt and pepper to suit your taste, or add herbs like thyme or parsley for added flavor.
- For a fun twist, mix in cooked vegetables or even leftover roast chicken.
- Feel free to experiment with different cheese types! Creamy mozzarella or spicy pepper jack can add a unique touch.

Recipe FAQs
Can I make this casserole ahead of time?
Absolutely! One of the greatest benefits of this casserole is that it can be prepared the night before. Simply assemble the layers, cover, and refrigerate overnight. In the morning, bake as directed.
What kind of bread works best?
Stale bread is ideal for this recipe. Options like sourdough, French, or even whole grain are great choices because they absorb the egg mixture better without getting too mushy.
Can I add vegetables to the casserole?
Yes, adding vegetables like spinach, mushrooms, or even zucchini is a wonderful way to boost nutrition and flavor. Just make sure to sauté them first to cook off any moisture.
How do I know when the casserole is done?
The casserole is done when the edges are golden brown, and a knife inserted into the center comes out clean or with minimal wetness. The eggs should be fully set, not jiggly.
