Ingredients You’ll Need

1 pound pork sausage: This provides the primary flavor base. Feel free to substitute with turkey sausage for a lighter option.
10 large eggs: Lightly beaten for fluffiness, eggs are key to this recipe. Make sure they’re fresh for the best flavor.
3 cups milk: Whole milk creates a rich, creamy texture. You can also use low-fat or non-dairy milk if desired.
1 teaspoon fine sea salt: This enhances all the flavors; avoid table salt, as it can alter the texture.
½ teaspoon black pepper: Freshly ground adds a hint of spice; adjust to taste!
6 cups cubed bread: Day-old bread works best for soaking up the custard. French or sourdough are delicious options.
2 cups shredded sharp cheddar cheese: Cheddar gives that gooey, melty goodness. Variations like Monterey Jack can be used for a milder flavor.
½ cup diced red pepper (optional): This adds a pop of color and sweetness. Feel free to skip or substitute with diced green bell pepper.

How to Make Breakfast Casserole | Easy Make-Ahead Father’s Day Brunch Bake

Preheat & Prepare: Preheat your oven to 325°F. Grease a 9x13x2-inch casserole dish to prevent sticking.
Cook the Sausage: In a large skillet over medium-high heat, cook 1 pound of pork sausage. Stir frequently until it’s thoroughly cooked and there’s no pink remaining. This should take about 8-10 minutes.
Whisk Egg Mixture: In a large bowl, whisk together 10 lightly beaten eggs, 3 cups of milk, 1 teaspoon of sea salt, and ½ teaspoon of black pepper until it’s fully combined.
Layer the Ingredients: Evenly distribute half of the cubed bread (3 cups) into the prepared dish. Sprinkle with half of the shredded sharp cheddar cheese (1 cup), half of the black pepper, half of the diced red pepper, and half of the cooked sausage. Repeat these layers with the remaining ingredients.
Add Egg Mixture: Pour the egg mixture evenly over the casserole, ensuring all the bread is soaked.
Refrigerate or Bake: At this point, you can cover the casserole and refrigerate it overnight for easier morning prep or bake it immediately.
Bake: Once ready, bake uncovered for 60-75 minutes, or until the eggs are set and not jiggly in the center. If the top begins to brown too quickly, loosely cover the dish with foil.
Serve: If desired, sprinkle with sliced green onions before serving. Enjoy this warm comfort food with loved ones!

Storing & Reheating

Any leftovers? You can store the casserole at room temperature for about 2 hours after baking. For longer storage, keep it in an airtight container in the refrigerator for up to 3 days. Want to save it for later? Freeze portions by wrapping them tightly in plastic wrap and then placing them in a zip-top freezer bag. It will keep well for up to 3 months. When you’re ready to eat, simply thaw in the fridge overnight and reheat in the oven at 350°F for about 20-25 minutes, or until heated through. The texture remains delicious, but a quick spray of cooking oil can refresh the top layer.

Chef’s Helpful Tips

Cook Thoroughly: Make sure the sausage is fully cooked before layering, as this ensures food safety and prevents an uncooked texture.
Room Temperature Ingredients: For best results, let the eggs and milk sit at room temperature for about 30 minutes before mixing. This helps the casserole bake more evenly.
Timing is Key: If you’re preparing this for brunch, start baking at least one hour before serving to allow adequate time for cooking and resting.
Texture Troubleshooting: If your casserole seems too dry, it may need more liquid next time. A little extra milk can do wonders.
Flavor Enhancements: Adding herbs like thyme, parsley, or even some hot sauce can amp up the flavors of this dish.
Make Ahead: You can prepare the layers in advance and just pour the egg mixture over right before baking. Perfect for a stress-free brunch!

From the first bite to the last, this breakfast casserole | easy make-ahead Father’s Day brunch bake is a delightful way to gather everyone around the table. You get the satisfaction of blending flavors beautifully and the joy of sharing this warm meal with family and friends.
