Crockpot Christmas Breakfast Ingredients

Hash brown potatoes, cheese and eggs are other main ingredients in this slow cooker breakfast recipe. For the veggies, I like to use red pepper, spinach and tomatoes. Heavy cream sour cream and butter give it a rich, luxurious mouthfeel and taste, while garlic and Dijon mustard add even more flavour.

Feel free to change up the veggies. Mushrooms would be good here, or you could swap the gouda for a different kind of cheese (cheddar cheese, mozzarella cheese, monterey jack or pepper jack cheese) in the brunch recipe.

Like other kinds of breakfast casserole recipes, you can switch ingredients. Perhaps you have some veggies in the salad drawer beyond their prime. Whether this is onion, mushrooms, zucchini, or another kind of vegetable, you can throw it in, in additional to the bell pepper, spinach and tomatoes, or instead of them. If you’d throw it in an omelet it will work fine in a breakfast casserole.

You could even swap the ham for cooked chicken, breakfast meat (such as breakfast sausage or turkey sausage) or even leftover turkey, else omit it for a vegetarian version. Leave out the cayenne pepper if you don’t want any spice at all, or sub chilli powder or smoked paprika instead if you wish.

Slow Cooker Overnight Breakfast Casserole FAQs

What’s the best way to store leftovers?

You probably won’t need to know this, since leftovers with this casserole dish are unlikely! But if you do have some left over, it should be fine for up to 5 days in a container in the refrigerator.

The easiest way to reheat this crockpot breakfast casserole recipe is to do it in portions in the microwave. You can also freeze it for up to two months. If you choose to do that, thaw overnight in the refrigerator and bake for 20 minutes at 350 degrees F, or until hot in the middle.

What’s good to serve with this?

You don’t need to have any holiday menu sides with this, since it’s already really filling, but a fresh fruit salad or a side of fruit would be good with this hash brown casserole. Also, if you’re having this as a breakfast or brunch treat on Christmas morning, consider pairing it with a mimosa or even a watermelon paloma. Don’t forget some tasty cinnamon rolls, too!
