Step‑by‑Step Instructions for Sausage and Egg Breakfast Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, lightly grease a 9x13-inch baking dish with non-stick spray or butter, ensuring every corner is covered. This step is crucial to prevent the casserole from sticking, allowing for easy serving once it’s baked to golden perfection.
Step 2: Cook the Sausage
In a large skillet over medium heat, add the ground breakfast sausage. Cook it for about 8-10 minutes, breaking it up with a spatula until fully browned and no longer pink. Once done, drain excess fat, then set the cooked sausage aside. The savory aroma will fill your kitchen, setting the stage for your delicious sausage and egg breakfast casserole.
Step 3: Cube the Bread
While the sausage cools slightly, take your day-old bread and cut it into bite-sized cubes—about 1-inch pieces work well. Spread these cubes evenly over the greased baking dish. This step not only adds texture but also ensures that each piece will soak up the creamy egg mixture beautifully, enhancing the overall flavor of the casserole.
Step 4: Whisk the Eggs
In a large mixing bowl, gather the large eggs and crack them open. Add in the full-fat milk or half-and-half, salt, and pepper. Whisk everything together vigorously for about 1-2 minutes until the mixture is well combined and slightly frothy. This egg mixture will be the base of your Sausage and Egg Breakfast Casserole, infusing it with a fluffy, custard-like consistency.
Step 5: Combine Ingredients
Once the egg mixture is ready, pour it evenly over the cubed bread in your prepared baking dish. Then, sprinkle the cooked sausage over the top and gently press it down to ensure the bread absorbs the egg mixture. You might see some liquid pooling at the bottom; this is perfect as it will cook into a deliciously moist casserole!
Step 6: Option to Refrigerate
If time allows, cover the baking dish with plastic wrap and refrigerate overnight. This step enhances the flavors and gives the bread time to soak up the egg mixture, resulting in a richer Sausage and Egg Breakfast Casserole. If time is tight, you can bake right away, just know the soaking time provides a deeper flavor profile.
Step 7: Bake to Perfection
When ready to bake, remove the casserole from the refrigerator and uncover it. Place the dish in your preheated oven and bake for 45-50 minutes. Look for a golden-brown top and a firm center; it shouldn’t jiggle when shaken. A knife inserted in the center should come out clean, indicating your sausage and egg breakfast casserole is ready to serve.
Step 8: Cool and Serve
Once the casserole is out of the oven, allow it to cool for about 10 minutes before slicing. This cooling period helps the casserole set further, making it easier to cut into beautiful squares. Serve warm and enjoy the delightful flavors of your homemade Sausage and Egg Breakfast Casserole with family and friends!

Sausage and Egg Breakfast Casserole Recipe FAQs
How do I choose the best ingredients for my casserole?
Absolutely! When selecting your ingredients, opt for fresh, large eggs for the best texture. The ground breakfast sausage can be pork or turkey based on your preference; consider using spicy sausage for a kick or turkey for a leaner option. Choose day-old bread like sourdough or French bread, as it absorbs the egg mixture best without turning mushy. Always check for any dark spots on the bread, indicating it's no longer fresh.

Very! After you've enjoyed the deliciousness, you can store any leftovers in an airtight container in the refrigerator for up to 3 days. Make sure it’s cooled completely before sealing, so it retains its delightful moistness. This way, you can enjoy the savory flavors another morning!
Can I freeze my casserole for later use?

Wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It can last up to 3 months in the freezer. To enjoy it later, simply thaw it in the fridge overnight before the bake-off.
What should I do if my casserole isn’t set in the middle?
Absolutely, this is a common issue! If you notice your casserole jiggling in the center after the recommended baking time, it might need more time in the oven. To troubleshoot, you can cover it loosely with foil to prevent over-browning and continue baking at 350°F until the center sets firmly—usually an additional 5-10 minutes should do the trick!
Are there any dietary considerations for this dish?
Very! If you’re serving individuals with dietary restrictions, this casserole can easily be modified. For those avoiding gluten, substitute the bread with gluten-free bread. If someone has a dairy allergy, try using a non-dairy milk and vegan cheese. As for pets, keep this dish out of their reach, as the high-fat and seasoning content isn't suitable for furry family members.
How long should I let the casserole cool before serving?
