How to Make

Step 1: Start by cooking your breakfast sausage in a skillet on the stove. Cook your sausage to crumbles and make sure it is fully cooked. 

Step 2: Once your sausage is cooked, drain off grease and set aside. 

Step 3: In a bowl add your eggs, milk, mustard, and salt. Mix until it is a nice scrambled mix. Pour in your cooled sausage, cheese and diced bread.

Step 4: Refrigerate the mixture in your baking dish. You can place it in the fridge for 8 hours to overnight. 

When ready to cook follow the baking directions in the printable recipe card below. 

Can I Add Bacon

Want to make this casserole into a double meat recipe? Go ahead and precook the bacon. Crumble and mix in when you mix in the sausage. 

What Is The Best Bread To Use

Honestly there is wiggle room on what bread to use for this casserole. 

French Bread, classic white sandwich bread, croissants, etc all work wonderfully. You will find depending on the bread you use the texture will vary a bit. 

Variations To Breakfast Casserole

  • Swap meat or add in more for a double or triple meat
  • Slice up peppers and onions to add more flavor 
  • Use mozzarella or even a pepperjack for a change of flavor
  • Etc

This casserole for breakfast is so versatile. Feel free to change up the flavors to fit your preference or what you have on hand. 

Storing Leftovers

You can place your sausage casserole in an airtight container and store in the fridge for up to three days. 

After that you will need to use your best judgement. In terms of freezing I would think this casserole could freeze nicely. The only thing is the bread could soften up quite a bit.

If you try you can freeze 2-3 months and just reheat it from frozen in the microwave for a quick and easy breakfast.

Do I Have To Let This Sit Overnight Before Baking

If you don’t want this to be an overnight dish, you can make and let it sit for 30 minutes before baking. That will allow the bread time to soak up the egg and milk mixture. 

Then bake as directed in the recipe card. You just want to ensure the eggs are fully cooked.
