Ingredients
To recreate this breakfast casserole with sausage, you will need the following ingredients. We focus on fresh, accessible items found in any US grocery store.

- 1 lb (450g) Breakfast sausage (ground pork, bulk style)
- 6-8 slices White bread, cubed (day-old bread works best) OR 1 can of refrigerated biscuits for an overnight egg and biscuit casserole style
- 2 cups (200g) Sharp Cheddar cheese, shredded
- 8 large Eggs
- 2 ½ cups (600ml) Whole milk
- 1 tsp Dry mustard powder
- 1 tsp Salt
- ½ tsp Black pepper
- ½ tsp Garlic powder
- Optional: 1/2 cup diced bell peppers or onions for added crunch
Equipment Required
Having the right tools ensures this Easy Sausage and Egg Casserole comes out perfectly cooked and easy to serve.
- 9×13 inch Baking Dish: Essential for even cooking.
- Large Skillet: For browning the sausage.
- Large Mixing Bowl: To whisk the egg mixture.
- Whisk: To ensure the custard base is smooth.
- Serrated Knife: For cutting the bread or biscuits.
Preparation Steps
Follow these detailed instructions to master this make-ahead brunch bake.
- Prepare the Meat: Preheat a large skillet over medium-high heat. Add the breakfast sausage and cook until browned and crumbled, ensuring no pink remains. Drain the excess grease thoroughly to prevent the casserole from becoming oily. Set aside to cool slightly.
- Prepare the Base: Grease your 9×13 baking dish with butter or non-stick spray. Spread the cubed bread (or cut biscuits) evenly across the bottom of the dish. If you prefer a potato base, you can substitute the bread with thawed frozen hash browns for a cheesy hash brown egg bake.
- Layer the Ingredients: Scatter the cooked, drained sausage over the bread layer. Next, sprinkle the shredded cheddar cheese generously over the meat. This layering ensures every bite is packed with flavor.
- Create the Custard: In a large bowl, whisk together the eggs, milk, dry mustard, salt, pepper, and garlic powder. Beat until the mixture is uniform and slightly frothy.
- Combine: Pour the egg mixture evenly over the casserole. Press down gently with a spatula to ensure all the bread absorbs the liquid.
- Rest (Optional but Recommended): Cover the dish with foil. For the best results, refrigerate for at least 1 hour or overnight. This step allows the bread to soak up the custard, resulting in a fluffy, soufflé-like texture.
- Bake: Preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and take off the foil. Bake for 45-50 minutes, or until the center is set and the top is golden brown.
- Serve: Let the casserole stand for 10 minutes before slicing. This helps the layers set, making it easier to serve.
Chef’s Tips and Variations
Here are some expert tricks to ensure your Easy Sausage and Egg Casserole is a success every time, along with variations to suit your needs.
- Make it Gluten-Free: To create a gluten-free sausage egg casserole, simply swap the standard bread for your favorite dense gluten-free loaf or use cubed potatoes.
- The Vegetable Twist: Add sautéed mushrooms, spinach, or peppers to the sausage mixture for extra nutrients. If you enjoy veggie-heavy dishes, you might also like our Crack Green Beans Recipe as a side.
- Spice it Up: Use hot Italian sausage or add a dash of cayenne pepper to the egg mixture for a kick.
- Leftover Magic: If you have leftovers from a holiday dinner, you can substitute the sausage. For example, chopped turkey from our Cranberry Orange Glazed Turkey Breast works beautifully.
- Storage: This is a freezer-friendly breakfast casserole. You can bake it, let it cool completely, and freeze individual squares for up to 3 months. Reheat in the microwave for a quick breakfast.

FAQ
Can I make this a cheesy hash brown egg bake instead of using bread?
Absolutely. Replace the bread cubes with a 30oz bag of frozen shredded hash browns (thawed and squeezed dry). This variation is delicious and naturally gluten-free if you check the potato packaging.
Is this a freezer-friendly breakfast casserole?
Yes. You can freeze the unbaked casserole (without eggs) or, preferably, bake it fully, let it cool, and freeze portions wrapped in plastic wrap and foil. Thaw in the fridge before reheating.
How do I make an overnight egg and biscuit casserole version?
Instead of bread slices, use a tube of refrigerated biscuit dough. Cut each biscuit into quarters and use them as the base. The result is a fluffier, more buttery texture similar to dumplings.
Can I use turkey sausage for a healthier option?
Yes, turkey sausage is a great lower-fat alternative. If you are looking for other high-protein meal ideas, check out our Grilled Steak Bowl with Creamy Sauce.
What if I don’t have time to let it sit overnight?
While overnight is best for texture, you can bake it immediately after assembly. Just ensure you press the bread down well into the egg mixture so it absorbs as much liquid as possible before hitting the oven.
