Breakfast Casseroles are great all year round!

I love a good breakfast bake any time of year…there’s just something so great about doing all the assembling for a dish in minutes, then popping it in the oven to bake. Pretty stress free. This is especially helpful during the holiday season when we’re all so busy planning, cooking and visiting! Anything we can do to alleviate some of our stress, I’m all for it!

This Easy and Cheesy Hashbrown Breakfast Casserole is SO delicious. I have made it several times for my family, and they love it! In fact, this is going to be on the menu Christmas morning this year…I plan on assembling it on Christmas Eve, then popping it in the oven in the morning while the kids open their gifts.

Let’s talk flavour!

This dish is so flavourful…made with eggs, cheese, hashbrowns, bacon, ham or sausage, onions and peppers…so many great flavours all in one dish. And all the things you love about breakfast all in one recipe…love that.

This dish is great as a stand alone meal, but it’s also great served with cinnamon buns and a fruit salad…a perfect brunch combination!

  • Eggs:  Make sure to whisk the eggs well. The egg/milk mixture should be smooth (sometimes I will give it a quick pulse with my hand blender).
  • Milk:  You can use whole milk, or even 2% milk. I prefer whole milk…it makes this dish creamy.
  • Cheese: You can use any kind of cheese for this dish. Our favourite is a Havarti and Monterey Jack blend, but cheddar cheese, marble and mozzarella work well too.
  • Meat: You can use ham, cooked and crumbled bacon, or cooked or crumbled breakfast sausage (pork sausage or turkey sausage) in this recipe.
  • Peppers: I add the equivalent of 1 cup of chopped bell peppers (red, green, yellow or orange all work).  You can add more if you like.
  • Hashbrowns: You can use either frozen or thawed shredded hash browns.  I use a 20 ounce bag, which is roughly 4 cups.
  • Garnish: Make sure to garnish with fresh green onion…they add the perfect finishing touch.

Hashbrown Breakfast Casserole Recipe Tips:

  • Pan Size: Use a 9×13 casserole dish for this recipe.
  • Let it Rest: Make sure to let this dish rest for at least 5 – 10 minutes so you can cut nice tidy squares.
  • Leftovers: Leftovers are delicious! Just store them in an airtight container in the fridge for up to 3 days. Reheat individual portions in the microwave.

    1. You can, but I do think it’s best the day it is made. My favourite make ahead tip for this recipe, is to assemble it the day before you want to serve it, then bake it fresh the next day.
