Ingredients You’ll Need

For the Casserole:

• 1 pound ground breakfast sausage: Choose pork or turkey sausage based on your preference.
• 8 large eggs: The base of this casserole, providing structure and protein.
• 1 cup milk: Helps create the fluffy egg texture.
• 1 teaspoon salt: For seasoning.
• ½ teaspoon black pepper: Adds a touch of spice.
• ½ teaspoon garlic powder: Enhances the overall flavor.
• 1 cup shredded Cheddar Cheese: For a rich, cheesy layer.
• ½ cup shredded mozzarella cheese: Adds a creamy, melty texture.
• 4 cups cubed bread: Use French bread, brioche, or any sturdy loaf to soak up the egg mixture without becoming soggy.

Optional Garnish:

• 1 tablespoon chopped parsley: Adds freshness and a pop of color.
• Additional toppings: Hot sauce, green onions, or a sprinkle of Parmesan for extra flavor.

Step-by-Step Instructions

1. Cook the Sausage

Start by heating a large skillet over medium heat. Add the ground breakfast sausage and break it into crumbles using a spatula. Cook the sausage until it’s browned and fully cooked, about 7-8 minutes. Be sure to stir occasionally to prevent burning. Once cooked, drain any excess grease using a paper towel or colander. Set the sausage aside to cool slightly.

2. Prepare the Egg Mixture

In a large mixing bowl, crack the eggs and whisk them until the yolks and whites are fully combined. Gradually add the milk, whisking continuously, to create a smooth mixture. Season with salt, black pepper, and garlic powder, ensuring the seasonings are evenly distributed. This mixture will serve as the binding agent for the casserole.

3. Layer the Ingredients

Grease a 9×13-inch baking dish to prevent sticking. Start by spreading the cubed bread evenly across the bottom of the dish to form the base. Next, sprinkle the cooked sausage over the bread, ensuring it’s distributed evenly. Follow by layering the shredded cheddar and mozzarella cheeses over the sausage, creating a cheesy layer that will melt beautifully during baking.

4. Chill and Soak

Pour the prepared egg mixture evenly over the layered ingredients in the baking dish. Make sure the bread is fully soaked by gently pressing it down with a spatula. Cover the dish tightly with plastic wrap and refrigerate for at least 30 minutes or overnight. This resting time allows the bread to absorb the egg mixture, resulting in a creamy and cohesive casserole texture.

5. Bake to Perfection

Preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature for 10 minutes to ensure even baking. Uncover the dish and place it in the preheated oven. Bake for 40-45 minutes, or until the eggs are fully set and the top is golden brown. You can check doneness by inserting a knife into the center—if it comes out clean, the casserole is ready.

Once baked, let the casserole cool for 5 minutes before slicing into squares. Garnish with chopped parsley or your favorite toppings for added flavor and presentation. Serve warm and enjoy!

Tips for Success

Soaking Bread

Allowing the casserole to rest in the refrigerator for at least 30 minutes or overnight is crucial. This soaking period lets the bread absorb the egg mixture fully, ensuring every bite is moist, flavorful, and cohesive. Skipping this step can lead to uneven texture or dry patches.

Customization

This recipe is highly adaptable to your preferences:

• Vegetables: Add bell peppers, spinach, mushrooms, or onions for extra nutrients and flavor.
• Proteins: Swap out the sausage for cooked bacon, diced ham, or even plant-based sausage for a vegetarian twist.
• Cheeses: Try swapping cheddar and mozzarella for Swiss, pepper jack, or Gruyere to mix up the flavor profile.

Storage and Reheating

• Refrigerator: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat individual portions in the microwave for 1-2 minutes or in the oven at 300°F (150°C) until warmed through.
• Freezer: To freeze, bake the casserole, let it cool completely, and cut it into portions. Wrap each portion tightly in plastic wrap and aluminum foil, or place them in an airtight freezer-safe container. Reheat from frozen at 350°F (175°C) for 20-25 minutes, or until hot.

FAQs

Can I use a different type of bread?

Absolutely! While French bread or brioche is recommended for its sturdy texture, you can use sourdough, whole-grain bread, or even gluten-free options. Just ensure the bread is slightly stale or toasted to absorb the egg mixture properly.

How do I make it vegetarian?

Can I freeze this casserole?

Yes! Bake the casserole first, let it cool completely, and cut it into portions. Wrap each piece tightly in plastic wrap and aluminum foil, or store them in an airtight freezer-safe container.
