Ingredients You’ll Need
- 1 pound pork sausage: Fresh sausage adds wonderful flavor; you can use turkey sausage as a lighter alternative.
- 10 large eggs: The base of the casserole, eggs bind everything together, creating that fluffy texture.
- 3 cups milk: Whole milk will yield a richer flavor, but feel free to use 2% or even non-dairy milk for a lighter twist.
- 1 teaspoon fine sea salt: Enhances flavors throughout the dish; adjust if you use salted sausage.
- ½ teaspoon black pepper: Adds a gentle kick; freshly cracked is always better for taste.
- 6 cups cubed bread: A crusty bread like French or sourdough works amazingly well. Day-old bread is even better for absorbing the egg mixture.
- 2 cups shredded sharp cheddar cheese: This cheese brings a fantastic tangy flavor; feel free to swap with mozzarella or pepper jack for variety.
- ½ cup diced red pepper (optional): For a pop of color and sweetness; you can replace it with other vegetables like spinach or mushrooms.
- Sliced green onion (optional): Adds freshness and a subtle bite when sprinkled on top before serving.
How to Make Breakfast Casserole | Easy Make-Ahead Father’s Day Brunch Bake
- Grease the Dish: Start by greasing a 9x13x2-inch casserole dish with butter or cooking spray to ensure easy serving later.
- Cook the Sausage: In a large skillet, cook 1 pound of pork sausage over medium-high heat, stirring frequently until thoroughly cooked and no longer pink. This step will fill your kitchen with a savory aroma.
- Whisk the Eggs: In a large bowl, whisk together 10 large eggs, 3 cups of milk, and 1 teaspoon of fine sea salt until completely combined; this will be the dressing for your casserole.
- Layer the Ingredients: Evenly distribute half of the cubed bread (3 cups) into the prepared casserole dish. Sprinkle with half of the shredded sharp cheddar cheese (1 cup), half of the black pepper (¼ teaspoon), and half of the cooked sausage (½ pound). If using red pepper, add half here as well. Repeat the layers.
- Add the Egg Mixture: Pour the egg mixture evenly over the casserole, ensuring that every piece of bread is soaked.
- Chill or Bake: Cover with plastic wrap and refrigerate overnight, or if you’re in a hurry, bake immediately.
- Preheat and Bake: Preheat your oven to 325°F. Bake uncovered for 60-75 minutes, or until the eggs are set. If you notice the top browning too quickly, loosely cover it with foil.
- Finish and Serve: For an extra touch, sprinkle sliced green onions on top before serving warm. Enjoy every bite!
Storing & Reheating
To store your breakfast casserole, let it cool completely, and then cover it tightly with plastic wrap or aluminum foil. It can be kept in the refrigerator for up to 3 days. If you’re looking for longer storage, wrap it well and freeze it for up to 3 months. When you’re ready to enjoy it again, simply thaw it in the refrigerator overnight and reheat in a preheated oven at 325°F for about 25-30 minutes until warmed through. Note that the texture might be slightly softer after freezing, but it will still be delicious!
Chef’s Helpful Tips
- Ensure your bread is a bit stale or toasted to prevent it from getting too soggy; this helps create a wonderful texture.
- Using room temperature eggs can give a fluffier casserole, making for a better final product.
- If you prefer crispy edges, consider baking directly from the fridge rather than letting it come to room temperature first.
- Experiment with extra ingredients such as diced tomatoes or spinach to suit your taste.
- For a flavorful kick, add some hot sauce or fresh herbs into the egg mixture.
The beauty of this casserole is not just in its taste but in its ability to bring people together; it’s a dish that sparks conversation and warmth around the dining table. It invites you to share stories while enjoying the rich flavors of a hearty breakfast. Feel free to personalize it with your favorite ingredients and make it your own.
