Step‑by‑Step Instructions for Martha Stewart Christmas Breakfast Casserole
Step 1: Prepare the Sausage
In a large skillet over medium heat, add the pork breakfast sausage and chopped yellow onion. Cook, stirring occasionally, for about 8-10 minutes until the sausage is browned and the onions are softened and translucent. This savory mixture is the foundation of your breakfast casserole, filling your kitchen with delicious aromas.
Step 2: Mix Custard
While the sausage is cooking, whisk together 8 large eggs, 2 cups of whole milk, 1 cup of heavy cream, 1 tablespoon of Dijon mustard, 1 teaspoon of salt, ½ teaspoon of black pepper, and a pinch of ground nutmeg in a large mixing bowl. Ensure the mixture is smooth and well-combined, forming a rich custard that will bind all your ingredients together beautifully.
Step 3: Layer Ingredients
Take a 9×13-inch baking dish and evenly distribute 6 cups of cubed sourdough bread across the bottom. Next, sprinkle the cooked sausage mixture and two kinds of cheese—1 cup of shredded Gruyère and ½ cup of grated Parmesan—over the bread. This layered approach creates a delightful blend of textures and flavors for your breakfast casserole.
Step 4: Pour Custard
Pour the egg custard mixture evenly over the layered ingredients in the baking dish, making sure to soak the bread cubes thoroughly. This step is crucial for achieving that creamy, custardy texture in your Martha Stewart Christmas Breakfast Casserole, so take a moment to gently press down the bread to ensure it’s all embraced by the custard.
Step 5: Chill
Cover the baking dish with plastic wrap or aluminum foil and place it in the refrigerator to chill for at least 1 hour, or preferably overnight. This allows the bread to absorb the custard, enhancing the flavors and resulting in a more cohesive breakfast casserole when baked.
Step 6: Bake
Preheat your oven to 350°F (175°C). Once ready, bake the casserole uncovered for 45-50 minutes, or until the top is golden brown and puffy. Keep an eye on it as it bakes; the final product should look inviting, with a slightly crispy top that hints at the comforting softness within.
Step 7: Serve
After baking, let the breakfast casserole rest for about 10 minutes before slicing it into squares. This resting period helps the casserole set up nicely so that each slice holds its shape. Serve warm, perhaps paired with a fresh winter fruit salad or crispy bacon to complete your festive breakfast spread.
Make Ahead Options
Preparing the Martha Stewart Christmas Breakfast Casserole in advance is a fantastic way to save time and make your holiday brunch stress-free! You can layer the ingredients and soak the bread in the custard up to 24 hours ahead of time by following the complete recipe instructions and then covering the baking dish tightly and refrigerating it overnight. This not only enhances the flavors but also ensures that the casserole maintains its creamy texture when baked. On Christmas morning, simply pop the casserole in a preheated oven at 350°F (175°C) and bake it for 45-50 minutes until golden and puffy. With these make-ahead tips, your casserole will be just as delicious, allowing you to soak in the festive spirit without the last-minute rush!
How to Store and Freeze Breakfast Casserole
Fridge: Store any leftovers in an airtight container and keep them in the refrigerator for up to 3 days. Ensure the casserole is completely cooled before sealing.
Freezer: If you want to extend its life, you can freeze the baked casserole for up to 2 months. Wrap it tightly in plastic wrap and then in aluminum foil for maximum freshness.
Reheating: To reheat, thaw it in the fridge overnight, then bake at 350°F for 20-30 minutes, or until heated through. Individual portions can be microwaved for easy serving.
Make-Ahead Tip: You can prepare the casserole a day in advance and simply pop it in the oven on Christmas morning, making it a perfect make-ahead breakfast casserole.

Expert Tips for Breakfast Casserole
-
Bread Soaking: Make sure to soak the sourdough bread in the custard long enough to avoid dryness. Day-old bread works best for absorption.
-
Chill Time: For optimal flavor and texture, chill the casserole overnight. This allows the ingredients to meld beautifully before baking.
-
Watch the Bake: Avoid over-baking your breakfast casserole; check for a puffed, golden top. It should feel set but still slightly jiggly in the center.
-
Ingredient Swaps: Feel free to experiment with cheese or add veggies like spinach for added nutrition. Customization will keep it exciting for everyone.
-
Allow to Rest: Let the casserole rest for about 10 minutes post-baking. This helps each slice hold its shape, making it easier to serve.
Martha Stewart Christmas Breakfast Casserole Recipe FAQs
How do I know if my ingredients are ripe or of good quality?
Absolutely! When selecting your ingredients, especially the bread, make sure it’s fresh but slightly stale for better absorption. Look for sourdough that’s crusty on the outside and soft inside, as it’s perfect. For the sausage, check the packaging for a fresher date, and if you opt for veggies, they should be crisp, vibrant, and free of blemishes.
How should I store leftover breakfast casserole?
For the best quality, store any leftover casserole in an airtight container and keep it in the refrigerator for up to 3 days. Make sure it’s completely cooled before sealing to avoid condensation, which can make it soggy. When you’re ready to enjoy it again, simply reheat until warmed through.
Can I freeze the breakfast casserole?
Yes, you can! To freeze the casserole, allow it to cool completely, then wrap it tightly in plastic wrap and aluminum foil. This will keep it fresh for up to 2 months. For the best texture, I recommend thawing it in the refrigerator overnight before reheating.
What if my casserole comes out too dry?
If your casserole is too dry, it might be that the bread didn’t soak up enough custard. In the future, ensure the bread chunks are fully immersed in the egg mixture before chilling. Additionally, avoid over-baking, as this can dry it out. If you find yourself with leftover dry casserole, try reheating it with a splash of milk or cream to restore moisture.
Is this breakfast casserole suitable for those with dietary restrictions?
Absolutely! This casserole can easily be adapted for dietary needs. For gluten-free options, use gluten-free bread and check that your sausages are gluten-free. If there are dairy allergies, non-dairy milk and cheese alternatives can work beautifully, though the texture might vary slightly. Always choose ingredients that suit your dietary requirements, and feel free to ask if you have any specific concerns!
How far in advance can I prepare this breakfast casserole?
Great question! You can prepare the casserole up to a day in advance. Just layer the ingredients and pour the custard over them, then cover and refrigerate overnight. This makes it super convenient for a stress-free Christmas morning. When you’re ready, just pop it in the oven, and you’re all set for a delicious breakfast!
