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

Preheat and Prepare: Grease a 9x13x2-inch casserole dish to prevent sticking. This size is perfect for reheating leftovers too.
Cook the Sausage: In a large skillet over medium-high heat, cook the pork sausage, stirring frequently until it’s browned and no longer pink. This should take about 5-7 minutes. Drain excess fat if necessary.
Mix the Egg Base: 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. Combine until everything is smooth and well integrated.
Layer the Ingredients: Spread half of the 6 cups of cubed bread in the prepared dish. Sprinkle with half of the 2 cups of shredded sharp cheddar cheese, followed by half of the diced red pepper and half of the cooked sausage. Repeat the layering with the remaining ingredients.
Pour the Egg Mixture: Evenly pour the egg mixture over the layered bread, sausage, and cheese, making sure it reaches all corners of the dish.
Chill or Bake: Cover the casserole dish with plastic wrap and refrigerate overnight if prepping ahead of time. If you’re ready to bake right away, skip this step.
Bake: Preheat your oven to 325°F. If chilled overnight, remove the plastic wrap and bake uncovered for 60-75 minutes, or until the eggs are set. The casserole is done when a knife inserted comes out clean. If the top begins to brown too quickly, loosely cover with foil.
Garnish and Serve: If desired, sprinkle sliced green onions over the top before serving. Enjoy this delicious breakfast casserole warm!

Storing & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. If you want to freeze this casserole, wrap it tightly in plastic wrap or aluminum foil and it’ll keep for up to 3 months. To reheat, simply pop it in the oven at 350°F for about 20-25 minutes, or until warmed through. Note that the texture may change slightly after freezing, but refreshing it with a quick bake usually brings back that cozy, homemade feel.

Chef’s Helpful Tips

To prevent a soggy casserole, use day-old bread or allow fresh bread to sit out for a few hours to dry slightly before cubing.
For a spicier kick, try using chorizo instead of sausage, or add diced jalapeños to the mix.
If you prefer a fluffier texture, separating the egg whites from the yolks, whipping the whites until frothy, then folding them back in before baking can make a difference.
Timing is key; keep an eye on your casserole towards the end of the baking time. Ovens can vary, so start checking the doneness at the 60-minute mark.
Feel free to experiment with vegetables! Spinach, mushrooms, or zucchini can add different flavors and nutrients.

Making this breakfast casserole for your loved ones is sure to become a cherished tradition! The best part? You can switch things up based on what you have on hand. Want to add more veggies? Go for it! Prefer a different cheese? No problem! As you get to know this dish, let your imagination and taste buds lead the way. Enjoy every spoonful and every moment shared around the table.

Recipe FAQs

Can I prep this casserole the night before?

Absolutely! This casserole is perfect for make-ahead preparation. Just assemble it the night before, cover with plastic wrap, and place in the fridge. Bake it fresh in the morning for an easy breakfast.

How do I know when the casserole is done?

The casserole is done when it’s puffed up, the top is lightly golden, and a toothpick or knife inserted into the center comes out clean. If the edges look done before the center is set, cover with foil to avoid over-browning.

Can I freeze the breakfast casserole?

Yes, you can! Make sure it’s in an airtight container or well-wrapped with plastic wrap or foil. It can be frozen for up to 3 months. Just thaw overnight in the fridge before reheating.

What can I substitute for the sausage?

If you’d prefer a vegetarian option, consider using sautéed vegetables or a meat alternative like veggie sausage. You can also omit the sausage altogether and add extra cheese and veggies for a delightful twist!
