Grandma’s Easy Sausage & Bacon Breakfast Casserole

With the holidays quickly approaching I wanted to make a holiday classic, something I have every year on December 25th, sausage & bacon breakfast casserole as made by my Grandma and Aunt.  This is an incredibly easy meal to make and highly delicious.

The ingredients

All you need for this meal is bread, eggs, bacon, sausage, milk (not pictured), green pepper, cheese, mustard powder, and salt.

Prepping the meat

I start with cooking the bacon.  This is probably the most time-consuming part next to cracking the eggs since I’m not a pro egg cracker by any means.  I cook 8 strips of bacon until they are nice and crispy.  The crispier the better in my opinion since it will eventually cook with wet ingredients making the pieces a bit softer.  While the bacon is cooking I cut up my sausage since I used pre-cooked and my local supermarket sells pre-cut green peppers which saves time.

Prepping the eggs

Start by cracking all the eggs into a bowl.  Make sure you use a pretty deep bowl because 9 eggs and 3 cups of milk plus everything else fills it up pretty good.  Once you have all the eggs cracked add your milk, mustard powder, and salt.  Mix it until the mustard powder is no longer chunky and the yolks are broken up nicely.  Don’t whisk the egg mix, just gently mix it (I used a fork).

Adding the bread, meat, cheese, and peppers

Once you’ve finished mixing the eggs it is time to add your bread.  Simply tear your bread into pieces, add to the egg mixture, and mix it together coating all the bread with eggs.  I used some leftover Italian bread rolls but really any bread will work for this recipe.

After you’ve added and mixed the bread it’s time to add the sausage, bacon, green peppers, and cheese.  Just toss it in and again mix it well until everything is incorporated nicely.

Baking your casserole

Now that everything mixed together with the eggs it’s time to get it in your casserole.  Lightly grease your 9×13″ casserole dish or tin, which is what I used because I didn’t want the dish after I finish this.  Simply pour the mix into the casserole and spread out evenly.  Place it in your pre-heated oven which is at 350 degrees for 45 minutes.  You will know when it is done when the eggs aren’t runny and the center doesn’t jiggle when you move it.
