Recipe Features
- Quick and Easy Breakfast- Mix and bake. Did I mention you can prep it ahead of time??
- Easy to Customize- We used sausage but you could easily use bacon or a mix of meats.
- Freezer Friendly Breakfast Recipe
This has every element of a good breakfast. The sausage, hash browns, eggs, Bisquick… It’s just a baking dish full of deliciousness and perfect for a crowd.
The beauty is that you can quickly cut it in half- making it perfect for a smaller family- OR double it for a large crowd. And did I mention it is also freezer friendly? That makes it ideal for busy weekdays.
I love it so much that I served it at the waffle bar baby shower I hosted for my darling sister in law. It was the star of the show. Somehow it shined through all of the sweet confections spread across the table and was gone in under 10 minutes.
Breakfast Bake Ingredients
All of the ingredients listed below are easy to adjust. You can even find pre chopped peppers and onions in the freezer section of most grocers- talk about convenient! You can also make this recipe ahead of time which plants it firmly as our go-to christmas breakfast casserole!
- Breakfast Sausage- I always reach for spicy breakfast sausage, but this would be equally delicious with a mild version. I do recommend not using maple sausage.
- Peppers and onion- Red and green pepper add a small punch of flavor to this already delicious breakfast casserole.
- Shredded Hash Browns- Found in the freezer section, these make all the difference in the texture of the dish.
- Cheese- We love a good cheddar, but you could easily substitute pepper jack or swiss!
- Bisquick- The secret ingredient. Bisquick pulls everything together and gives it a sturdy shape. Don’t have any on hand? Try making your own with this easy pancake mix recipe.
- Milk- We use 2% milk for almost every recipe. This specific dish would be fine with whole or skim.
- Eggs- Large eggs.
- Salt and Pepper- Season to taste. Want more bang? Add a pinch of garlic powder!
