Ingredients List

Transform your kitchen into a breakfast haven with these carefully selected ingredients that create the perfect harmony of flavors and textures:

Protein Foundation:

Egg Custard Base:

• 1/2 teaspoon salt – Essential for enhancing all flavors
• 1/2 teaspoon black pepper – Adds gentle warmth and complexity

Flavor Enhancers:

• 1/4-1/2 teaspoon cayenne pepper (optional) – For those who crave a gentle heat kick
• 1/2 teaspoon ground mustard – Provides subtle tanginess and depth
• 1 teaspoon dried sage – The aromatic herb that elevates breakfast sausage to new heights
• 1/2 teaspoon dried chives – Fresh, onion-like notes that brighten the dish

Cheese Blend:

• 1 1/2 cups yellow sharp cheddar cheese, shredded – Delivers bold, tangy flavor

Bread Base:

• 10 slices butter bread or sandwich bread, cubed – The foundation that soaks up all those delicious flavors overnight

Step-by-Step Instructions

Step 1: Prepare the Sausage Foundation

Cook and crumble the breakfast sausage in a large skillet over medium-high heat until no longer pink, approximately 8-10 minutes. Transfer to a paper-towel lined plate to drain excess grease – this step prevents your casserole from becoming soggy and ensures optimal texture.

Step 2: Create the Custard Magic

In a large mixing bowl, whisk together eggs, salt, black pepper, cayenne pepper, ground mustard, dried sage, dried chives, and half-and-half until completely combined. The mixture should be smooth and well-integrated – this custard base is what transforms ordinary ingredients into breakfast perfection.

Step 3: Layer for Success

Butter a 13″x9″ baking dish generously. Layer the cubed bread evenly across the bottom, followed by the drained sausage, then both cheeses. This strategic layering ensures even distribution of flavors throughout the casserole.

Step 4: The Overnight Transformation

Pour the custard mixture over the layered ingredients, ensuring all bread pieces are fully submerged. Gently press down any floating bread pieces. Cover tightly with plastic wrap or a lid and refrigerate overnight – this crucial step allows the bread to absorb the custard, creating that signature texture.

Step 5: Morning Baking Ritual

Remove the casserole from refrigeration and let it sit at room temperature while preheating your oven to 350°F. This prevents thermal shock and ensures even cooking. Bake uncovered for 45-50 minutes until the top is light golden brown and the center is set.

Step 6: The Perfect Rest

Allow the casserole to rest for 5 minutes before serving – this brief pause allows the custard to fully set and makes slicing effortless.
