Breakfast Casserole For Crowds and Meal Prep

Add this breakfast casserole to your Pinterest board for brunch recipes right now before you forget! This hearty and savory meal is appreciated among guests who come hungry, as they should in any Italian household. I had to say it! Jim always makes fun of me when I reference myself being Italian (a whole 25%), so now I share my Italianness sarcastically to get a rise out of him.

Anyways, this breakfast casserole is not only perfect for crowds but also perfect for weekly food prep and freezer meals. It tastes just as good when you pop it in the microwave days later! You can also adapt this recipe to make smaller amounts or use on-hand ingredients.

When I’m cooking for mass quantity, I make the breakfast casserole in a large 15″ by 10″ Pyrex casserole dish. On the other hand, when I want to whip up a smaller amount using what’s already in my fridge, I use a pie dish. My pie dish is also Pyrex; it’s vintage from my mom – I love the rare color of it and yearn for vintage palettes.

Now, let’s hop into the breakfast casserole recipe! The recipe below is for the large casserole dish version, but if you’d like to make a smaller pie dish version (like in my photo), you can use about 6-8 eggs and adjust vegetables and sausage accordingly. I rarely measure; I often place the frozen vegetables and sausages in the pie dish as my measurement prior to cooking, just so I know how much to heat up.

Equipment

• 2 Large Lidded Pans
• 1 Large Casserole Dish
• 1 Chopping Board
• Utensils

Ingredients

  

• 12 Large Eggs
• 1 Bag Shredded Cheddar Cheese You can easily use different cheese if you already have on-hand! You won't be using the whole bag necessarily. I just eyeball my sprinkles of cheese as I add in.
• 1 Bag Frozen Diced Potatoes This might also be labeled hash browns. Make sure to get plain to avoid added salt. I like to keep it as healthy as possible!
• 1 Bag Frozen Onions
• 1 Bag Frozen Chopped Bell Peppers Feel free to use fresh onions and peppers instead. I like to keep it easy by using frozen, pre-chopped veggies. A frozen onion/pepper stir fry mix works too.
• 1 Bag Breakfast Sausage Patties
• 1 Ground Pepper
• 1 Can Cooking Spray

Instructions

 

• Preheat the oven to 350F.
• In the large casserole dish, add frozen potatoes, onions, and peppers to measure out the amount you should heat up. The vegetables should fill a thick, generous layer at the bottom of the dish.
• Heat up a drizzle of olive oil in large lidded pan and add the portioned potatoes, onions, and peppers. Defrost and cook on medium/high.
• While the veggies are cooking, use the same method of using the casserole dish to measure out how many sausage patties you'll need.
• Follow sausage cooking instructions. (For the large casserole, you may want to do in a pan versus microwave since there are so many!)
• Don't forget to stir the veggies throughout this process so they cook even and don't burn!
• Now, spray the casserole dish with cooking spray.
• Crack the dozen of eggs directly into the casserole dish, add a splash of water, and whisk right in the dish. (I used to use a separate prep bowl for cracking and whisking until I realized I could be more efficient!)
• When the veggies are done (potatoes should be browned), add directly into the casserole dish with the whisked eggs.
• When the sausage patties are done, chop up into smaller pieces and add into the casserole dish as well.
• Add ground pepper and generous layers of sprinkled cheese.
• Mix all ingredients in the casserole dish around with a utensil and add a final sprinkle of cheese on top.
• Cover the casserole dish with tinfoil (or maybe you have a lid!)
• Bake in oven for 35 minutes.
• Check how the casserole is looking at 35 minutes. This is when you'll likely remove the tin foil and cook for 15-20 more minutes. You'll know the casserole is done when it's no longer liquidy.
• Remove from oven and serve!
