Best Christmas Morning Breakfast Casserole Recipe

Best Christmas Morning Breakfast Casserole Recipe is the ultimate festive delight. Prepare ahead and enjoy a cozy, flavorful morning.

Ingredients

• 6 slices toasted white bread (cut into 1-inch squares)
• 1 lb ground pork sausage (Jimmy Dean’s works great)
• 1 1/2 cups half and half (gives better texture and moisture)
• 2 cups shredded sharp cheddar cheese (freshly shredded for best melt)
• 1/2 tsp salt
• 6 beaten eggs

Instructions

Step 1: Prepare the Baking Dish and Cook the Sausage

Grease a 9×13 baking dish thoroughly and set it aside so it's ready when you need it. Heat a skillet and cook the ground pork sausage over medium heat until every bit is nicely browned; drain away excess fat and let the meat rest briefly so it stops steaming. The goal here is a deeply browned, slightly crumbled sausage with crisped edges and savory juices locked in — perfect contrast to the soft bread and custard that follow.

Step 2: Mix Ingredients Together

In a medium mixing bowl, whisk the half and half, beaten eggs, and salt until the custard is silky and slightly frothy. Fold in the warm cooked sausage, the toasted bread cubes, and the freshly shredded sharp cheddar, stirring until the bread is evenly coated and the cheese begins to cling to the pieces. You want a wet-but-structured mixture where bread is saturated but still holds shape and cheese threads through the custard.

Step 3: Assemble the Casserole

Pour the mixed, custardy bread-and-sausage mixture into the greased 9×13 dish, smoothing the top so the pieces sit evenly. Cover tightly with foil and place the dish in the refrigerator to chill for at least two hours or overnight; chilling helps the custard fully hydrate the bread for a uniformly tender interior when baked.

Step 4: Bake the Casserole

Preheat the oven to 350°F and place the foil-covered casserole into the oven to bake for 50–60 minutes. This covered baking step allows the custard to set gently and the flavors to meld without over-browning while the interior firms up.

Step 5: Finish Baking Uncovered

Lower the oven to 325°F, remove the foil, and continue baking for another 20–30 minutes until the center is set and the top turns a deep golden brown. The edges should caramelize slightly and create a crispy frame around a tender, custardy middle with melted cheese peeking through.

Step 6: Serve and Enjoy

Let the casserole cool briefly so it firms for clean slices, then garnish as you like and serve warm — perfect for a cozy Christmas morning shared with family. The top should be bubbling, golden, and studded with browned sausage; the interior should be souffle-like and richly savory.

Notes

• Prepare the casserole the night before for best results.
• Substitute sausage with mushrooms for a vegetarian option.
• Freshly shredded cheese melts better.
