Multigrain Bread makes this breakfast casserole healthier

Using multigrain bread for this recipe adds in some of that good stuff your body needs to give you continuous energy throughout the day. You can use any bread you prefer, but I recommend something hearty and dense to really hold you over until lunch.

Can This Recipe be Gluten Free?

If you have dietary restrictions or just prefer to eat gluten free, you can definitely make this make ahead sausage breakfast casserole with your favorite gluten free bread. However, I do not recommend letting it sit overnight. Since GF bread does not have the same chewy interior and crusty exterior of a hearty bread, it will lose all shape and become mushy. So just put together right before baking and you should be good to go!

Need to Make this breakfast Dairy Free?

Easy peasy! My preference is to replace the milk with Oat Milk as it has a creamier texture and the flavor does not become overwhelming when heated (like Almond milk tends to do). For the Monterey Jack cheese, you can replace with a cheese substitute (although this is never my favorite option as it does not melt very well) or go for a goat cheese if you can handle goat (I can't do cow cheese, but I love goat or sheep cheeses!).

Sweet and Savory Breakfast for the win!

I always prefer a sweet and salty breakfast to just one or the other. How about you? My husband loves all the sweet breakfast stuff. But this make ahead sausage breakfast casserole keeps everyone happy. The sweet potato and syrup drizzled on top gives it just the right amount of sweet. And the egg mixture, cheese and chicken sausage keeps it savory and full of flavor—creating the ultimate breakfast combination in one simple dish.

Make this breakfast casserole the night before

It doesn't take really long to make this sausage breakfast casserole, but I still recommend putting it together the night before. Therefore, you can wake up and just throw it in the oven with no effort. Because no one wants to labor in the kitchen in the morning, and I absolutely love it when I set my future-self up for success. This is also a perfect breakfast for company. You can easily double the recipe and bake in a 9x13 pan to feed a crowd.

Here at The Oven Light, we are always looking for ways to cut cooking time in half (or more!). We use shortcuts that don’t sacrifice flavor, we’re just getting smarter with our time. You won’t find “dump” meals here, but rather an approach to cooking that is mindful and intentional with time AND taste.
