How to Make Martha Stewart’s Christmas Breakfast Casserole
This simple, make-ahead breakfast casserole comes together in just a few easy steps:
Step 1: Brown the Sausage and Vegetables
In a large skillet, cook the breakfast sausage over medium heat, breaking it apart with a spoon as it cooks. Once browned, add the chopped onion and red bell pepper to the pan, cooking for an additional 3–4 minutes until the vegetables soften.
Step 2: Prepare the Egg Mixture
In a large bowl, whisk together the eggs, half-and-half, salt, pepper, and Dijon mustard. Stir in the shredded cheeses until well combined.
Step 3: Assemble the Casserole
Grease a 9×13-inch baking dish. Layer the cubed bread in the bottom of the dish. Evenly spread the cooked sausage and vegetable mixture over the bread. Pour the egg mixture over the top, making sure to saturate the bread completely. Gently press the bread down to ensure everything is coated in the egg mixture.
Step 4: Let It Sit or Refrigerate
For the best results, cover the casserole and refrigerate it overnight, allowing the bread to soak up the egg mixture. If you’re short on time, you can let it sit for 30 minutes to 1 hour at room temperature before baking.
Step 5: Bake the Casserole
Preheat your oven to 350°F (175°C). Bake the casserole for 45–55 minutes, or until it is golden brown on top and the center is set. You can check the doneness by inserting a knife into the center—if it comes out clean, the casserole is ready. Garnish with fresh parsley before serving.

Serving Suggestions for Christmas Breakfast Casserole
While the casserole itself is hearty and filling, you can serve it with some tasty sides to round out your holiday breakfast or brunch:
- Fresh fruit: Serve with a light fruit salad for a refreshing contrast to the rich casserole.
- Crispy bacon or sausage links: Add extra protein to make it a more substantial meal.
- Roasted potatoes: Serve alongside crispy roasted potatoes or hashbrowns for a comforting, filling meal.
- Mimosas or holiday-themed cocktails: Pair with festive drinks like mimosas or spiced cider for an extra touch of holiday cheer.

Common Mistakes to Avoid
To ensure your casserole turns out perfect every time, avoid these common mistakes:
- Not letting it soak long enough: Make sure to let the bread soak in the egg mixture overnight for the best texture.
- Underbaking: Bake the casserole until it’s golden brown and the center is firm. If the top is getting too brown, cover with foil and continue baking until done.
- Using the wrong bread: Choose a hearty bread like French bread or challah. Avoid using sliced sandwich bread, as it won’t hold up as well.
