Simple Slow Cooker Sausage and Hashbrown Egg Casserole

I love big, rich breakfasts but I don’t love waking up early to *make* big, rich breakfasts.

One morning I knew we’d have a hectic Saturday and wanted to try out a slow cooker egg casserole recipe that was made in a crockpot. I know…. eggs and a slow cooker? I shuddered a bit and figured it was worth a shot.

And man, was it ever! This Slow Cooker Sausage Hashbrown and Egg Breakfast Casserole will make anyone look like a domestic goddess who has a healthy relationship with mornings.

How to make Slow Cooker Sausage Hashbrown Egg Casserole

To make Slow Cooker Sausage Hashbrown Egg Casserole you’ll need:

  • Frozen hash browns or country potatoes – Potatoes make this breakfast hearty and help the eggs have something to hold their shape.
  • Salt and pepper – salt and pepper are essential to have a well seasoned tasty breakfast dish. Season each piece to taste when serving. 
  • Basil and oregano – basil and oregano are both great flavor powerhouses and will give this casserole an aromatic flavor direction. 
  • Sausage crumbles – sausage is high in fat and gives this breakfast a higher protein content and a rich flavor.
  • Eggs – eggs are the binder here. Use high quality eggs for the best flavor and texture. 
  • Mozzarella cheese – mozzarella is high in fat and flavor and also helps to bind the breakfast slow cooker casserole. As a plus it adds a rich delicious cheese flavor.

Once you assemble all the ingredients, make the slow cooker sausage and hashbrown egg casserole using the following method:

Prep. Grease the bottom of the slow cooker well with cooking spray. Add the potatoes/hash browns and seasonings and toss. 

Layer. Add the sausage on top of the potatoes, spread the cheese over the sausage. In a small bowl mix the eggs, milk, and hot sauce until frothy. Pour the eggs over and top and cover with the lid.

Cook. Cook on low for 7-8 hours or high for 4-5 hours or until eggs are puffy and firm. Remove the lid and let casserole sit for about 15 minutes to set before enjoying!

Tips and Tricks

Check out these tips and tricks for mastering this recipe.

Tip 1 – Do NOT skip the seasoning step, or season out of order – YOU NEED TO SEASON THE POTATOES, WELL. You might want to sprinkle a little salt and pepper on the top of the dish, according to your tastes, but don’t skip seasoning the potatoes well. Add salt, pepper, herbs, and toss them so its coated well. Do this before you add all the other ingredients- or you will end up with bland, flavorless potatoes. Trust me on this one!

Tip 2 – You can also cook on high. Halve the cook time by switching your slow cooker to high, it makes the sides very brown and crunchy. I have the instructions set to low because that is how I like my casserole- but cooking on high for 3-4 hours works too, I just prefer how it turns out on low better.

FAQs

Can I leave out the sausage?

You don’t need to add the sausage to make this casserole. If you leave it out the result will be less rich since you lose the fat from the meat. You can add some sautéed vegetables of your choice.

What other cheeses can I use?

You can use any cheese for this recipe. I prefer a cheese that will melt easily so the casserole comes together easier.

How long will leftovers last?

Leftovers will keep in an airtight container for 3-4 days in the refrigerator.

    Hi what did you put on the top after? Thanks!

    1. Courtney ODell says:

      Tomato and diced green onion 🙂

  2. Karen says:

    Would this work with fresh potatoes?

    1. Courtney ODell says:

      I haven’t done them, but I don’t see why not. The only thing I’d do is maybe toss them in a bit of oil first to be sure they really won’t stick!
