- 1 teaspoon fine sea salt: Essential for enhancing flavors; adjust to taste depending on your preference.
- ½ teaspoon black pepper: A must for seasoning, but feel free to add cayenne if you love a little heat.
- 6 cups cubed bread: Stale or day-old bread works perfectly—brioche or sourdough adds great flavor.
- 2 cups shredded sharp cheddar cheese: This cheese melts beautifully and adds a savory richness; feel free to mix in Monterey Jack for a different twist.

How to Make Breakfast Casserole | Easy Make-Ahead Father’s Day Brunch Bake
- Prep the casserole dish: Grease a 9x13x2-inch casserole dish generously to prevent sticking—nobody enjoys a stuck casserole!
- Cook the sausage: In a large skillet, cook 1 pound of pork sausage over medium-high heat, stirring frequently until it’s entirely cooked through and no longer pink—this should take about 10 minutes.
- Whisk together the egg mixture: In a large bowl, whisk together 10 large eggs, 3 cups of milk, and 1 teaspoon of fine sea salt until the mixture is thoroughly combined and frothy—this adds a nice texture.
- Layer the ingredients: Evenly distribute half of 6 cups of cubed bread into your prepared casserole dish. Then sprinkle with half of the 2 cups of shredded sharp cheddar cheese, half of the ½ teaspoon of black pepper, half of the diced red pepper if you’re using it, and half of the cooked sausage. Repeat this layering.
- Pour the egg mixture: Carefully pour the egg mixture evenly over the layered casserole, covering all the ingredients.
- Refrigerate or bake: At this point, you can cover the dish and refrigerate it overnight for an easy morning prep. If you’re eager to bake, you can pop it in the oven right away.
- Bake to perfection: Preheat your oven to 325°F. Bake the casserole uncovered for 60-75 minutes, or until the eggs are set and slightly golden. If the top begins to brown too quickly, loosely cover it with foil to prevent burning.
- Garnish and serve: If desired, sprinkle with sliced green onions for a fresh finish. Serve warm, and enjoy the smiles around your table!
Storing & Reheating
This casserole is perfect for leftovers! Store any uneaten portions in an airtight container at room temperature for up to 2 hours, or refrigerate for up to 3 days. If you want to keep it longer, you can freeze it for up to 3 months. Just be sure to wrap it tightly. To reheat, bake it at 325°F for approximately 20-30 minutes until warmed through. The texture may be slightly different than when fresh, but you can refresh it with a sprinkle of cheese or some fresh herbs on top!
Chef’s Helpful Tips
- Avoid overcooking the sausage to keep it juicy. Cook it just until it’s browned and crumbly.
- Let your eggs come to room temperature before mixing; this helps them whisk up better.
- If your casserole puffs up during baking, that’s totally normal! It will settle as it cools.
- Feel free to boost the veggie count by adding favorites like spinach or mushrooms in the layers.
- If layering the bread gets too soggy, toast the bread lightly before assembly; this helps it hold up during baking.
- This casserole is fabulous for make-ahead brunches—just prep and bake when you’re ready!
When you serve this Breakfast Casserole for your Father’s Day brunch, you’re not just serving a dish; you’re creating a moment of togetherness that’s warm and inviting. The ease of preparation and delicious result is sure to make this recipe a keeper for years to come.
