Ingredients for Crockpot Breakfast Casserole

Take your breakfast to the next level with this crockpot breakfast casserole! Easy ingredients with simple ingredients that cook together perfectly. The best crockpot breakfast casserole is a crowd-pleaser!

• Sausage – Add protein to this chopped sausage. Cut the sausage into even bite-sized chunks.
• Eggs – This is the base of the breakfast casserole. Eggs are filled with nutrients and are a great source of protein.
• Milk – Adds creaminess and moisture to the egg mixture. Milk helps the eggs fluff up and become lighter.
• Potatoes – Frozen diced potatoes with red and green bell peppers.
• Tomato – Slice and chop the tomato into small pieces that are added to the crockpot.
• Cheddar cheese – Give this crockpot breakfast casserole that gooey cheesy texture with shredded cheddar cheese. Shred the cheddar cheese for it to slowly melt throughout the breakfast casserole.

Steps to Cooking Crockpot Breakfast Casserole

If your Crockpot cooks hot or if you have an oval one it may only take six hours on low. A smaller, round crockpot may take the full 8 hours to cook through the center. To make clean-up even easier try using a crockpot/slow cooker liner!

1. Cook – Brown sausage links in a large skillet until cooked through and cut into pieces. Set aside.
2. Whisk – In a large bowl, whisk the eggs and milk together. Add salt and pepper.
3. Combine – Spray the crockpot with cooking spray and layer the cut-up sausage, potatoes O’Brien, tomatoes, and cheese. Pour the egg mixture over the top. Stir everything together.
4. Slow cook – Cook on low heat for 6 to 8 hours. The oval crock pots like the one shown may cook faster than the typical round crock pots. Try to aim for the 6-hour mark if using one like this.

Tips for the Crockpot Breakfast Casserole

Follow these helpful tips to make a delicious crockpot breakfast casserole! Making this breakfast will be a family favorite. Your morning will be better waking up to a full-filling breakfast!

• Grease the crockpot – Make clean up even easier! Grease with nonstick cooking spray, and butter, or use a crockpot liner to keep the breakfast casserole from sticking to the sides.
• Layer – Make sure to layer the ingredients individually. This will help the structure of the breakfast casserole hold together and be stable as well as cook properly.
• Evenly distribute – When pouring in or placing the ingredients, try to evenly distribute the ingredients in the slow cooker breakfast casserole. Each bite will have a little bit of all the ingredients. This will help the ingredients from being overcooked or undercooked.
• Cooking time – Cooking times can vary depending on the size of the crockpot.
• Don’t overcrowd – Try not to overfill the crockpot with ingredients. If it is overcrowded then the ingredients will not be able to cook properly.
• Toothpick trick – Check to make sure the crockpot breakfast casserole is done by inserting a toothpick into the middle of the slow cooker. If the toothpick comes out clean, the breakfast casserole is cooked properly.
• Let it rest – Before serving, let the breakfast casserole sit and let the flavors enhance for a few minutes before cutting and serving.

Variations for the Crockpot Breakfast Casserole

Our recipe for Crockpot breakfast casserole is very flavorful with the simple ingredients we use. We love it this way, but we have also tried variations depending on what we are in the mood for and what we have on hand.

• Potatoes – I love using the Potatoes O’Brien because they are already chopped and they come with red and green bell peppers. This just speeds up the process for me and makes this recipe even easier. However, you can use any frozen hash brown variation. You can even use fresh grated potatoes, but the casserole will cook up a lot quicker with fresh as opposed to frozen.
• Meat – I like using sausage links because it is what my family prefers, but you can use any breakfast meat you have on hand! It just needs to be cooked first. Feel free to use sausage, bacon, turkey bacon, or ham. If meat isn’t your thing, you can use meat substitutes, or no meat at all!
• Veggies – If you have got it in the fridge, it can go in this recipe (almost, haha). We’ve used peppers, onions, green onions, mushrooms, spinach, kale, green chiles, zucchini, tomatoes, and asparagus, just to name a few. If you can find it on an omelet bar, chances are it will taste delicious in this recipe!
• Cheese – Cheddar is an obvious breakfast choice, but you can change it up! Any cheese that melts well will work. We’ve used Swiss, mozzarella, pepper jack, Monterey jack, and Colby jack before. They’ve all been great!
• Toppings – Everyone in my family likes topping this casserole with something different. We’ve tried ketchup, sour cream and salsa, sriracha, avocado, chives, cheese, and Tobasco, just to name a few. Whatever you top this with, we know you will love it!
