Pro Tip: This recipe can be assembled the night before, reducing morning prep time to just 5 minutes—perfect for busy weekdays or special occasions.

Step-by-Step Instructions

Step 1: Prepare Your Foundation

Preheat your oven to 350°F (175°C) and generously butter a 9×13-inch baking dish. In a large skillet over medium heat, cook the sausage, breaking it into bite-sized pieces with a wooden spoon. Cook for 8-10 minutes until golden brown and fully cooked, with internal temperature reaching 160°F.

Step 2: Build the Vegetable Base

Add diced onion and bell pepper to the sausage, cooking for 3-4 minutes until softened. Stir in minced garlic and cook for another 30 seconds until fragrant. This aromatic base creates the flavor foundation that sets your casserole apart from ordinary breakfast dishes.

Step 3: Create the Egg Mixture

In a large mixing bowl, whisk together eggs, milk, Dijon mustard, smoked paprika, thyme, and seasonings. The key is whisking vigorously for 2-3 minutes to incorporate air, creating a fluffier final texture. This technique increases volume by approximately 20%.

Step 4: Layer with Purpose

Spread cubed bread evenly in your prepared baking dish. Top with the sausage and vegetable mixture, then sprinkle with 1.5 cups of cheese, reserving the remainder for later. Pour the egg mixture slowly and evenly over everything, ensuring all bread pieces are moistened.

Step 5: The Perfect Bake

Cover with aluminum foil and bake for 30 minutes. Remove foil, sprinkle with remaining cheese, and continue baking uncovered for 15-20 minutes until the center is set and the top is golden brown. A knife inserted in the center should come out clean.

Step 6: Rest and Serve

Allow the casserole to rest for 10 minutes before cutting. This crucial step prevents the casserole from falling apart and allows flavors to meld perfectly.

Common Mistakes to Avoid

Moisture Management Issues: The #1 mistake is using fresh bread instead of day-old bread, which creates a soggy texture. Day-old bread absorbs liquid perfectly while maintaining structure.

Temperature Troubles: Cooking at too high a temperature (above 375°F) causes the eggs to curdle and become rubbery. Maintain 350°F for even, gentle cooking.

Timing Errors: Rushing the resting period results in a casserole that falls apart when cut. Those 10 minutes of patience make the difference between presentation success and failure.

Seasoning Oversights: Under-seasoning the egg mixture is common—remember that eggs need more salt than you might expect. Taste the mixture before baking and adjust accordingly.

Storing Tips for the Recipe

Refrigeration Guidelines: Store covered casserole in the refrigerator for up to 4 days. Individual portions reheat more evenly than whole casserole pieces.

Freezer-Friendly Options: This casserole freezes beautifully for up to 3 months. Wrap tightly in plastic wrap, then aluminum foil, and label with date. Thaw overnight in refrigerator before reheating.

Reheating Best Practices:

• Oven method: 325°F for 20-25 minutes, covered with foil
• Microwave: Individual portions for 1-2 minutes on 70% power
• Make-ahead strategy: Assemble completely, cover, and refrigerate overnight before baking

Meal Prep Success: Cut cooled casserole into individual portions and store in meal prep containers. Each portion reheats in 90 seconds, perfect for grab-and-go breakfasts throughout the week.
