Sausage Breakfast Casserole Recipe

Looking for a special morning treat for a fun holiday celebration? This Sausage Breakfast Casserole is a classic, and is my go-to recipe and will become yours as well! The best part is it doesn’t need to rest overnight.

This sausage, egg, and cheese breakfast casserole recipe is SUCH an easy breakfast idea!

I’m a huge casserole lover because they’re so simple to make and this breakfast version is no different. Hands down, this is one of the best ones I’ve made. Your family is going to go nuts when you make this and they will ask for it each and every holiday season, so be prepared. Print it out and put it in your recipe binder or your holiday binder to keep every year.

Why This Recipe Works

Quick and Easy – This one is a breakfast dish like we all crave during the holidays. It doesn’t have to sit overnight, so if you are short on time or (gasp!) forget to prepare breakfast altogether, this can prepped for the oven in 20 minutes. So, do the dishes, swap out laundry and it’s ready to go.

Packed Full of Flavor – The flavor here is awesome and you will love it. It is breakfast comfort food that is just begging for a big mug of coffee or a sweet treat on the side to make it a completely indulgent morning.

Versatile – Swap out the meat or add in veggies for extra nutrients without losing flavor at all.

🥚 Ingredients

Sausage – I used a mild flavored sausage for this, but it is easy to include a spicy or herb flavored variety as well. There are a lot of eggs and bread in this recipe, so the spicy flavors won’t be overwhelming.

Cheese – Cheddar cheese is the classic ingredient here. Change it up for a more mild American cheese or add in some smoked cheese to really enhance the flavors.

🍽️ Instructions

Step One: Preheat the oven to 350 degrees and spray a 9×13 baking dish with cooking spray.

Step Two: Brown the sausage in a skillet and drain well. Let it drain thoroughly, otherwise the final casserole will turn out a bit greasy. Blech!

Step Three: Slice the bread into cubes. I used a white sandwich bread this time, but have used both sour dough and french bread in the past. They all work really well. I happened to have the white loaf bread and wanted to save a few bucks.

Step Four: Add eggs, milk, garlic and salt and pepper to a large bowl and whip until frothy. The whipping process will add air to the eggs and allow the casserole to be light and fluffy after it is cooked.

Step Five: Add the bread cubes, sausage and cheese to the egg mixture. Toss it gently to make sure the bread is thoroughly coated. Cover and let site in the refrigerator for at least 20 minutes. This time is needed so the bread can soak up the egg mixture.

Step Six: Pour the mixture into the casserole dish and top with the remaining cheese.

Step Seven: Bake at 350 for 30-45 minutes. Check it at 30 to see if the center is cooked through. Some ovens cook hotter than others, so I left a time range here.

💡 Expert Tips

This is a great recipe for meal prepping. Cube the bread and make the egg mixture the night before. Cover the eggs and keep them in the fridge. In the morning, whip the eggs and combine with the other ingredients. This will save you time, and allow you to spend time with your family in the morning.

I mentioned it above, but give sourdough bread a shot here. It is slightly tangy and really adds a fun flavor.

If you’re looking for an easy breakfast dish for Christmas mornings or holidays, this is the one! It’s super simple to make, uses simple ingredients you probably already have on-hand and it’s a definite crowd pleaser!

Notes

I recommend using a 9×13 baking dish, however any casserole dish that’s large enough to fit the mixture will work. 

Substitute hash browns if you don’t want to use bread.

Cook this until it reaches 160 degrees. Definitely use a food thermometer here.

Freeze leftovers for up to three months.  Defrost and reheat in the oven for about 20-25 minutes or in the microwave for about two minutes.

This stays good in the refrigerator for up to 3-4 days. 

To make this in muffin tins: Use a measuring cup to add the mix to muffin tins.  Set the timer for 20 minutes and adjust from there. You will look for the egg to set and solidify to show it is completely done! I love the idea and that fact that you could do this and freeze premeasured breakfasts for the week ahead.
