Effortless Mornings Coming Up

I love to prepare delicious meals for my family. Unfortunately, I don’t always have a lot of time to put into said meal. It can be really frustrating to try and pull a hearty breakfast together for a big day when you’re short on time.

No one enjoys all of the scrambling around the kitchen, trying to rush food prep and prepare for a big day, holiday or event in a rush. Parents also don’t want to chance dealing with hungry, cranky children.

My children, all now adults, were famously known for getting “hangry.” I have to say, they got it honestly, because their Dad doesn’t deal well with hunger pangs either. I can’t tell you the number of times when our children were growing up, that one of them would come in the house and say, “Mom, you either need to feed Daddy or put him down for a nap!” 😂

Recipe Explanation

Let me walk you through the simple steps to create the mouthwatering Sausage and Egg Breakfast Casserole. This easy-to-assemble dish requires just a handful of ingredients, making it perfect for those mornings when time is short but appetites are big.

Here’s what you’ll need:

  • 8 slices of bread (preferably day-old or slightly stale)
  • 2 pounds of ground breakfast sausage
  • 1 can of cream of mushroom soup
  • 3/4 cup of shredded cheddar cheese
  • 4 large eggs
  • ½ cup of milk
  • 12 oz. can of evaporated milk

This assembles very quickly, with most of your time being spent in browning the sausage. The rest is so easy, my six year old grandson could do it. Some of my family enjoy topping their sausage and egg breakfast casserole with salsa. It would also be delicious to sauté a cup of chopped mushrooms and add them in before baking.

Reasons to Prepare the Casserole Overnight

When it comes to breakfast casseroles, the overnight prep is key. In this section, I want to share with you why refrigerating the sausage and egg breakfast casserole overnight is important and how it affects both the taste and convenience.

Enhanced Flavors and Melded Ingredients

One of the main reasons why I love preparing this casserole the night before is that it allows the flavors to meld together. As the casserole sits in the refrigerator, the sausage, eggs, and other ingredients blend together, creating a delicious, creamy flavor. The overnight refrigeration process infuses the casserole with flavor that just isn’t possible with a quick mix-and-bake method.

Convenience in the Morning Rush

Busy mornings can be super chaotic, and the last thing you need is the added stress of scrambling to prepare a delicious breakfast. By prepping the sausage and egg breakfast casserole the night before, you can simplify your morning routine and ensure a hassle-free start to the day.

This casserole takes one hour to bake. It works out perfectly for me, because I put it in the oven when I wake up and then I can forget about it while I prepare for the day ahead. It’s the best feeling in the world to see smiling faces and warm tummies with so little effort.

IMPORTANT – Don’t Preheat the Oven

I did want to stress here that you DO NOT WANT TO PRE-HEAT THE OVEN if you are using a glass baking dish. Your casserole has been sitting in the refrigerator overnight and the glass is completely chilled. If you put a cold glass dish in a preheated oven, you’ll most likely end up with a shattered dish.

Glass expands and contracts with sudden temperature changes. If you put an ice cold baking dish in your heated oven, it will cause the glass to shatter and could result in an injury.

Some glassware, and particularly Pyrex brand, are no longer thermal-shock proof. Thus putting a cold dish inside of a hot oven will most likely result in shattered glass everywhere.

My trick to resolve this issue is to set out my casserole 10-15 minutes at room temperature, then I put my refrigerated dish into a cold oven and allow it to gradually warm as the oven warms.

Time-Saving Benefits

You can even use this time-saving trick for holiday brunches or family gatherings when you have a lot on your plate.

FAQs

Why is my breakfast casserole soggy?

There are a few reasons why your breakfast casserole may turn out soggy:

First, it’s important to make sure that you have drained any excess moisture from the ingredients, such as cooked sausage or sautéed vegetables, before adding them to the casserole. Excess moisture can contribute to a soggy texture.

Second, be sure to follow the recipe’s instructions regarding the amount of liquid to add. Adding too much liquid can result in a watery casserole.

Lastly, make sure not to overcook the casserole. Overcooking can cause the eggs to release more liquid, leading to a soggy outcome. It’s best to cook the casserole until it is set and lightly golden on top.

What’s the difference between a frittata and an egg casserole?

While both frittatas and egg casseroles are delicious egg-based dishes, there are some key differences between the two:

A frittata is an Italian-style dish that is typically cooked in a skillet on the stovetop and finished under the broiler. It is cooked slowly over low heat, resulting in a tender and custard-like texture. Frittatas often contain a variety of ingredients, such as vegetables, cheeses, and meats, all mixed together with the beaten eggs. They are usually served in slices.

On the other hand, an egg casserole is baked in the oven and often prepared by layering ingredients, such as eggs, meats, vegetables, and cheese, into a baking dish. The casserole is then baked until the eggs are set and the top is golden brown. Egg casseroles can serve a larger number of people and are often cut into squares or rectangles to serve.

Why do you have to refrigerate a breakfast casserole overnight?

Refrigerating a breakfast casserole overnight allows time for the flavors to meld together and for the bread or other base ingredients to absorb the liquid mixture. This step enhances the overall taste and texture of the casserole. Additionally, overnight refrigeration saves you time in the morning by allowing you to simply place the casserole in the oven, rather than having to assemble it from scratch.

How long can an egg and sausage casserole sit out?

It is important to follow proper food safety guidelines when it comes to serving and storing an egg and sausage casserole. If the casserole has been left out at room temperature for more than two hours, it is advisable to discard it to prevent any risk of foodborne illness. To prolong the shelf life of the casserole, it is recommended to refrigerate any leftovers promptly and consume them within three to four days.
