Step‑by‑Step Instructions for Egg, Sausage, and Bread Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step is crucial as it ensures that your Egg, Sausage, and Bread Casserole bakes evenly, resulting in a perfectly set center and a golden top. While the oven warms up, gather your baking dish and grease it well with butter or cooking spray to prevent sticking.
Step 2: Prepare the Bread Base
Once the oven is ready, take your stale bread and cut it into bite-sized cubes. Layer the bread evenly at the bottom of your greased baking dish, creating a sturdy base for the casserole. This bread will soak up the delicious egg mixture as it bakes, lending to a delightful texture that’s hearty and satisfying.
Step 3: Cook the Sausage and Veggies
In a skillet over medium heat, add the breakfast sausage, breaking it apart with a spatula as it cooks. Sauté until golden brown and fully cooked, about 5-7 minutes. Next, stir in the mushrooms and spinach, cooking until the veggies are softened and fragrant, around 3-4 minutes. This mixture will enhance the flavor profile of your Egg, Sausage, and Bread Casserole.
Step 4: Whisk the Egg Mixture
In a large mixing bowl, whisk together the eggs, milk, and shredded sharp cheddar cheese until well combined. Add your desired seasonings, such as salt and pepper, to taste. This creamy mixture will create a rich custard that binds the casserole and adds wonderful flavor to every bite.
Step 5: Combine and Pour
Carefully combine the cooked sausage and vegetable mixture into the egg mixture, ensuring everything is evenly coated. Pour this flavorful filling over the layered bread in the baking dish, making sure it seeps down to the bottom so each piece of bread is soaked with the mixture, ready to create a savory Egg, Sausage, and Bread Casserole.
Step 6: Bake to Perfection
Place the baking dish in the preheated oven and bake for approximately 50 minutes. Keep an eye on it; the casserole is ready when the center is set and has a beautiful golden-brown top. You’ll know it’s finished when you insert a knife and it comes out clean—this means your casserole is cooked just right.
Step 7: Cool and Store
Once baked, remove the casserole from the oven and allow it to cool for about 10-15 minutes before serving. This resting time helps the casserole set further for easier slicing. If you have leftovers, store them in an airtight container; they can be refrigerated for up to 5 days or frozen for longer enjoyment.

Egg, Sausage, and Bread Casserole Recipe FAQs
What type of bread is best for the casserole?
Absolutely! Stale bread is ideal for this casserole, as it helps to create a firm structure without getting soggy. You can use any type you like, but for a gluten-free version, I recommend using gluten-free bread that’s been dried out a bit. Aim for bread that’s a few days old for the best results.
How should I store leftovers from the casserole?
Very easy! Once your Egg, Sausage, and Bread Casserole is cool, you can store leftovers in an airtight container in the refrigerator for up to 5 days. Just be sure it’s completely cooled before sealing to keep the texture just right!

Can I freeze the casserole?
Absolutely! For freezing, slice the casserole into individual portions and wrap each piece tightly in plastic wrap. Place them in a freezer-safe bag for up to 3 months. When you’re ready to eat, simply thaw in the refrigerator overnight and reheat in the oven. This keeps it fresh and delicious!
What if I don’t have fresh spinach or mushrooms?
No worries! You can substitute with frozen vegetables; just make sure to thaw and drain them first to prevent excess moisture. Alternatively, bell peppers or zucchini make excellent substitutes, adding different flavors to your Egg, Sausage, and Bread Casserole.
Is this casserole suitable for pets or people with allergies?
Great question! This casserole contains common allergens like dairy and eggs, so it’s not suitable for those with lactose intolerance or egg allergies. For pets, it’s best to avoid feeding them this dish as ingredients like onion and certain cheeses can be harmful. Always check your ingredients for any specific allergies you might have.
What can I do if my casserole turns out soggy?
Very often, sogginess comes from using fresh bread or not letting your casserole cool properly before storage. To fix a soggy casserole, make sure to use stale bread next time, and try adding slightly less milk to your egg mixture. If it’s already made, baking it for an additional 10-15 minutes can help firm it up a bit.
