Step‑by‑Step Instructions for Sausage Cheese Strata
Step 1: Prepare the Baking Dish
Begin by greasing a 13×9-inch baking dish with butter or non-stick spray to prevent sticking. This essential step ensures that your Sausage Cheese Strata comes out easily after baking. Set the greased dish aside, allowing you to move on to the savory filling without interruption.
Step 2: Cook the Sausage
In a large skillet over medium heat, cook the ground sausage, breaking it up with a spoon until it’s browned and cooked through, about 8-10 minutes. Once browned, transfer the sausage to a plate lined with paper towels to drain excess fat. This step adds rich flavor to your strata, making it both hearty and delicious.
Step 3: Sauté the Onions
In the same skillet, add the diced onions and sauté until they become translucent, approximately 5 minutes. Stir occasionally to prevent browning. After that, return the cooked sausage to the skillet and mix everything for an additional 1-2 minutes to combine the flavors. Remove from heat and set aside.
Step 4: Whisk the Egg Mixture
In a large mixing bowl, whisk together the eggs, milk, Dijon mustard, salt, garlic powder, and pepper until well combined, creating a smooth custard base for your Sausage Cheese Strata. Stir in the grated cheddar cheese until evenly incorporated. This mixture will bind all your delicious ingredients together.
Step 5: Assemble the Strata
Spread the bread cubes evenly across the bottom of the prepared baking dish, providing a sturdy base for the strata. Layer the sautéed sausage and onion mixture over the bread, distributing it evenly. This step ensures every bite is packed with flavor and texture, making your breakfast truly satisfying.
Step 6: Pour the Custard Mixture
Slowly pour the prepared egg mixture over the bread and sausage layers, ensuring every piece is soaked in the custard. Use a spatula to gently push down on the bread cubes if needed, allowing the liquid to absorb completely. The bread should look moist but not swimming in the mixture.
Step 7: Refrigerate Overnight
Cover the assembled strata with plastic wrap and refrigerate it overnight, or for at least 8 hours. This resting period allows the flavors to meld together and the bread to absorb the custard fully, ensuring a deliciously rich Sausage Cheese Strata when baked.
Step 8: Preheat the Oven
About 20 minutes before you plan to bake, remove the strata from the refrigerator and allow it to sit at room temperature. Preheat your oven to 350°F (175°C), ensuring it reaches the right temperature for even cooking. This step helps in achieving a golden, perfectly baked breakfast casserole.
Step 9: Bake the Strata
Uncover the dish and place it in the preheated oven. Bake for 40-50 minutes, or until the egg is set and a knife inserted in the center comes out clean. The top should be golden brown and slightly puffed. This visual cue indicates a deliciously cooked Sausage Cheese Strata, perfect for serving.
Step 10: Serve and Enjoy
Once baked, allow the Sausage Cheese Strata to rest for 5-10 minutes before slicing. This resting period helps the casserole hold its shape. Serve warm, and enjoy the delightful combination of flavors and textures that make this breakfast dish a true comfort food favorite.

Sausage Cheese Strata Recipe FAQs
What type of bread is best for Sausage Cheese Strata?
I recommend using stale bread for the best texture, as it absorbs the egg custard beautifully. If you have fresh bread, you can dry it out by cutting it into cubes and letting it sit out for a few hours. You can even toast it lightly, which will help achieve that soft yet custardy consistency.
How long can I store leftovers of the Sausage Cheese Strata?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. However, be sure to let it cool completely before storing. When you’re ready to enjoy it again, simply reheat individual portions in the microwave or warm up the whole dish in the oven at 350°F until heated through.
Can I freeze Sausage Cheese Strata?
Absolutely! To freeze, wrap the assembled strata tightly in plastic wrap followed by aluminum foil to prevent freezer burn. It can be frozen for up to 2 months. When you’re ready to serve, thaw it in the refrigerator overnight, then reheat it in a preheated oven at 350°F for about 20-25 minutes—cover with foil to avoid over-browning while it warms up.
What if my eggs are not well combined in the custard?
If you notice streaks of uncooked egg in your strata after baking, it means the egg mixture wasn’t whisked thoroughly. To avoid this, take the time to mix well in a large bowl, ensuring the eggs, milk, and other ingredients are smooth and evenly combined. This guarantees a creamy texture throughout your Sausage Cheese Strata.
Can I customize the ingredients for dietary restrictions?
Very! This recipe is quite flexible. For a lighter version, feel free to substitute ground sausage with turkey sausage or a vegetarian option like mushrooms and spinach. Additionally, for lactose-free needs, you can use non-dairy milk and vegan cheese. This way, everyone at your brunch can enjoy the delightful flavors of the Sausage Cheese Strata, no matter their dietary preferences.
What should I do if I want to prepare it ahead of time?
Great question! You can assemble the Sausage Cheese Strata the night before. Just cover it with plastic wrap and submerge it in the refrigerator overnight. This allows the bread to soak up all that creamy goodness and develop rich flavors, so you’ll have a delicious breakfast ready to pop in the oven the next morning.
