Ingredients
- 6 large eggs
- 2 cups whole milk
- 1 teaspoon mustard
- 1 teaspoon salt
- ½ teaspoon freshly cracked pepper
- 6 slices of white bread, cubed
- 1 ½ cups shredded cheddar cheese (plus more for topping)
- 16 oz breakfast sausage (cooked and drained)
- 8 oz bacon (cooked and chopped)
Preparing the Casserole

Greasing the Baking Dish
Start by greasing a 9×13 baking dish with non-stick spray and set it aside. This simple step will ensure that every bit of that beautiful casserole comes out smoothly for serving.
Mixing the Egg Mixture
In a large bowl, beat the eggs until they’re nice and fluffy. Then, add the whole milk, mustard, salt, and freshly cracked pepper. Stir everything together until well combined. You want the mixture to feel light and airy, perfect for soaking into the bread.
Adding the Bread and Meats
Now, gently fold in the cubed white bread, shredded cheddar cheese, and your cooked and drained sausage and bacon. Mix until everything is evenly distributed throughout the egg mixture. This is where the magic starts to happen, and you can practically taste it already!
Pouring into the Dish
Pour the assembled mixture into the prepared baking dish, spreading it evenly. Once it’s all in, cover it tightly with plastic wrap. Don’t forget to refrigerate it for at least 8 hours or, even better, overnight. This gives the flavors plenty of time to develop, resulting in a delectable casserole that you’ll be proud to serve.
Baking the Casserole
Prepping to Bake
When you’re ready to bake, remove the casserole from the fridge about 30 minutes beforehand. Allowing it to come to room temperature will make for more even cooking. During this time, preheat your oven to 350°F, so it’s nice and hot when you’re ready to bake.
Baking Instructions
Bake uncovered for about 40 minutes. The goal is to ensure that it sets perfectly. When done, insert a knife into the center; it should come out clean. You’ll know it’s ready when that delicious golden topping beckons you to dig in!
Serving Suggestions
Once out of the oven, serve immediately while it’s still hot. If you’re a cheese lover (who isn’t?), add an extra sprinkle of cheese on top for that gooey finish. Pair your masterpiece with fresh fruit or a light salad. This will not only balance out the flavors but also bring a refreshing touch to the hearty casserole.
Tips for Success
To truly elevate your Overnight Bacon and Sausage Breakfast Casserole, here are some helpful tips. Ensure that the bread you use is slightly stale; this will help it absorb the egg mixture better. Feel free to customize with your favorite spices or herbs; a little bit of paprika or fresh chives can go a long way in adding depth. Finally, allowing the dish to rest before baking is key for even cooking, ensuring that every bite is just right.
Variations
Want to shake things up a bit? Try swapping out cheddar cheese for pepper jack if you prefer a spicy twist. Alternatively, using croissants or whole grain bread will definitely bring a unique texture to the casserole. You can also incorporate some veggies like spinach or bell peppers for a nutritious boost. The possibilities are truly endless!
Storage Tips
After you’ve enjoyed this delicious dish, you may wonder about storing leftovers. Keep them in an airtight container in the refrigerator, where they will stay good for up to three days. Reheat individual portions in the microwave or oven. Although, for the ultimate experience, this casserole is best enjoyed fresh right out of the oven!
Pairing Ideas
To enhance your breakfast experience, consider serving the casserole with:
- Freshly brewed coffee for that perfect morning pick-me-up.
- A glass of orange juice or mimosas for a festive touch.
- A variety of seasonal fruits that add a refreshing side.
