Ingredients You’ll Need
- 1 pound pork sausage: A flavorful base that adds richness to the casserole. You can substitute turkey sausage for a lighter option or use vegetarian sausage for a meatless dish.
- 10 large eggs, lightly beaten: These provide the structure and texture. Make sure to let them sit at room temperature for easier mixing.
- 3 cups milk: Adds creaminess. Whole milk is ideal for richness, but you can use skim or almond milk for a lighter version.
- 1 teaspoon fine sea salt: Enhances all the flavors. You can adjust to taste, especially if you’re using a salted sausage.
- ½ teaspoon black pepper: A simple yet essential spice that adds warmth. Feel free to add in some cayenne for a kick.
- 6 cups cubed bread: Use sturdy bread like French or sourdough for the best texture. Leftover bread works great too!
- 2 cups shredded sharp cheddar cheese: Melts beautifully and brings a sharp tang. Swap with pepper jack cheese for some heat or mozzarella for a milder taste.
- ½ cup diced red pepper (optional): Adds color and sweetness. You can replace it with any favorite bell pepper or skip it altogether.
- Sliced green onion (optional): For garnish and a fresh crunch. Fresh herbs like parsley can also elevate the flavor.
How to Make Breakfast Casserole | Easy Make-Ahead Father’s Day Brunch Bake
- Prep the Casserole Dish: Grease a 9x13x2-inch casserole dish with cooking spray to prevent sticking.
- Cook the Sausage: In a large skillet, cook 1 pound of pork sausage over medium-high heat. Stir frequently until it’s thoroughly cooked and no longer pink, about 5-7 minutes. Drain excess fat if necessary and set aside.
- Whisk Egg Mixture: 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 until well combined.
- Layer Ingredients: Evenly distribute half of the 6 cups cubed bread into the prepared casserole dish. Then sprinkle with half of the 2 cups shredded sharp cheddar cheese, half of the black pepper, half of the diced red pepper, and half of the cooked sausage. Repeat with the remaining ingredients.
- Add Egg Mixture: Pour the egg mixture evenly over the layers in the casserole dish.
- Refrigerate or Bake: Cover the casserole and refrigerate it overnight for the best flavor melding. If you want to bake it immediately, preheat the oven to 325°F.
- Bake: Bake uncovered for 60-75 minutes, or until the eggs are set and the top is golden. If browning too quickly, loosely cover with foil.
- Serve: If desired, sprinkle the casserole with sliced green onions and serve warm, allowing the flavors to shine.
Storing & Reheating
Store leftovers at room temperature for up to two hours, then transfer them to an airtight container and refrigerate. They’ll stay fresh for up to 3 days. For longer storage, you can freeze portions for up to 3 months; just wrap tightly in foil. When reheating, warm it in the oven at 350°F for 20-25 minutes, or until heated through. Keep in mind that the texture may change slightly after freezing, but reheating with a sprinkle of cheese can refresh its deliciousness.
Chef’s Helpful Tips
- Be careful not to overcook the sausage; keep it juicy for maximum flavor in the casserole.
- Room temperature eggs whisk more easily, leading to a creamier texture in the finished dish.
- For melted cheese perfection, save a little cheese to sprinkle on top during the last 10 minutes of baking.
- If your casserole feels too runny after baking, it may need more time in the oven to firm up.
