FAQ About Quick Overnight Sausage and Egg Casserole
Can I use a different kind of sausage?
Absolutely! You can swap the breakfast sausage for turkey sausage, chicken sausage, or even plant-based sausage alternatives. It’s a great way to suit your taste preferences and dietary needs.
How long should I bake the casserole?
The casserole typically takes about 30-35 minutes at 350°F (175°C) to bake. It is done when it has puffed up, is golden brown on top, and a knife inserted in the center comes out clean.
Can I make this casserole vegetarian?
Certainly! Simply replace the sausage with sautéed mushrooms, bell peppers, or crumbled tofu. You can still enjoy the creamy texture and delicious flavor without the meat.
What type of bread works best for this casserole?
You can use any bread you prefer! Options like classic white or whole wheat bread work well. If you’re feeling adventurous, try using brioche or sourdough for a unique flavor profile.
Can I prepare this recipe without mustard?
Yes, if mustard powder is not to your taste or if you don’t have any on hand, you can skip it. The casserole will still be delicious without it. You can also try substituting it with a dash of your favorite hot sauce for some added flavor.
How can I ensure my casserole doesn’t get soggy?
Using day-old bread can help to absorb the egg mixture better and prevent the casserole from becoming too soggy. Make sure to allow the casserole to rest before cutting into it, as this will allow it to firm up nicely.
