Basic Ingredients for a Ham and Egg Crockpot Casserole

- Milk – low-fat or regular milk is fine.Â
- Salt and Pepper – to taste.
- Garlic Powder – to give your casserole a bit of flavor.Â
- Frozen Shredded Potatoes – keep them frozen, especially if you are cooking overnight. (aka frozen hash browns)
- Ham – fully cooked and chopped/diced into bite-sized pieces.Â
- Onion – chopped. It can be omitted if serving kids or sensitive adults.Â
- Cheese – shredded sharp cheddar is our go-to to give the casserole plenty of flavor.
How To Make a Breakfast Casserole in Your Crock Pot
First, gather all your ingredients for your crockpot breakfast casserole recipe, Then, grate your cheese and chop your onions and ham and let’s put this casserole together!
Step 1
Crack your eggs and then whisk together the first five ingredients in a medium bowl.
Step 2
Next, grease or spray your crock with a non-stick spray. Now, place a third of your frozen shredded potatoes in the bottom of a 5-6 quart slow cooker.
Now, layer with a third of each of the following ingredients: ham, onion, and cheese. Repeat the layers twice more.
Step 3
Pour your egg mixture over the top of your layers.
Step 4
Finally, cook covered on low heat until eggs are set and the edges begin to brown, about 5-6 hours. Let stand about 30 minutes before serving.
What Variations or Add-Ins Can you Make To Your Ham and Egg Crock-Pot Casserole?
When cooking for picky eaters, you can just serve your casserole as is, however, if you want to add some veggies, try these:
- Broccoli – goes perfectly with the ham and cheese.
- Bacon or Sausage – don’t have ham on hand; go for cooked bacon or sausage. Both are amazing. If you really feel like you need a hearty meal, pick two!
- Red onions – replace the yellow onions with red onions for a slightly different flavor.
- Bell Peppers – any color pepper will be good.
- Spinach – an excellent way to add some color and nutrition.Â
- Tomatoes – a mild recipe addition that pairs well with onion and spinach.Â
- Mild Green Chilis – or if you’re feeling spicy, try jalapeños!Â
- Other Cheeses – you could pertaining use pepper jack or a combination of cheeses in the recipe.
Of course, you can mix and match any of these variations, depending on what you and your guests like.

How Long Do You Cook a Breakfast Casserole in Your Crock-Pot?
This is one of the questions we get a lot.
If using frozen shredded hash browns, cook your crockpot breakfast casserole on low for about 5-6 hours. The edges will begin to brown, and the egg should be set.
When cooking overnight, put your casserole on to cook right before you go to bed. It will switch to warm once it’s done but definitely check it as soon as you wake up.

How Long Does A Breakfast Casserole Keep?
If you store the recipe properly in the refrigerator in an airtight container, your casserole will be good for about 5 days.
Thankfully, to make things stress-free, you can cook this recipe a day ahead of time and reheat it when ready to serve.
To reheat, bake in the oven in an oven-safe dish until heated through or microwave a serving for roughly 1-minute.
Tip: Because the shredded potatoes were previously frozen, we don’t recommend freezing the casserole again after being cooked.
Tips for Making An Overnight Egg Casserole In Your Slow Cooker
- Since the egg tends to stick, make sure you use a non-stick spray or some grease (butter, etc.) in your crock insert before adding your ingredients. You can use a slow cooker liner, but they tend to create more waste for the environment, so we don’t recommend them.
- With the recipe itself being mild, we like using sharp cheddar cheese. However, you can use whatever cheese you prefer in the recipe.
- The casserole is done when it starts to get nice and crispy around the edges, and the egg is thoroughly cooked.
