There are a lot of low-carb breakfast casserole recipes on this blog, so when I bought the new Casserole Crock Slow Cooker (affiliate link) with the crockery part in the shape of a casserole dish, at first I didn’t think of using it for a breakfast casserole. But then one day it hit me how perfect this would be for those times when you want to make breakfast for a crowd, and I knew I had to start experimenting.

It took me two tries to get the amounts right, but I loved this Slow Cooker Sausage and Egg Casserole. My niece Kara tested it with me the second time, and we enjoyed the creaminess (and extra protein) the cottage cheese added, and the way that cooking an egg dish in the slow cooker makes the flavors of the other ingredients get infused into the eggs.  

If you don’t have the Casserole Crock Slow Cooker (affiliate link) and if you’re not interested in adding it to your collection of slow cookers, just put these ingredients into a large casserole dish and bake at 375F for about 40 minutes. No worries! Or see after the recipe for suggestions if you’d like to adapt this recipe to use in an oval-shaped 6-Quart Slow Cooker or the 6-Quart Ninja Cooker. (Affiliate links)

What ingredients do you need?

(This is only a list of ingredients; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

  • cottage cheese
  • turkey breakfast sausage links
  • olive oil, divided
  • green pepper
  • grated cheddar cheese
  • green onions
  • Spike Seasoning (affiliate link) or other all-purpose seasoning blend
  • fresh ground black pepper to taste
  • eggs

How long do you need to cook a Crock Pot Breakfast Casserole?

This type of egg casserole frees up the cook for a little over 2 hours while it cooks in the slow cooker. If it’s not done after two hours in the slow cooker you’re using, cook it until the eggs are firm and the cheese is nicely melted.

Why make egg casserole in the slow cooker?

Slow Cooker Egg Casserole frees up the cook to do something else while the crock pot egg casserole is cooking, so it’s perfect to make when you have houseguests. And this type of “baking” infuses the egg with the flavors of the other ingredients a bit more than simply cooking it in the oven.

What If I Don’t Have the Casserole Crock Slow Cooker?

Look in the NOTES section of the complete recipe to see my suggestions for adapting this recipe to use a six-quart oval slow cooker.

How to make this Crock Pot Breakfast Casserole:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

  1. I used Jenni-O Turkey Breakfast Sausage Links, and browned them before they went into the slow cooker. (For those who are wondering, Jenni-O is not paying me to mention their sausage; I just love it.)
  2. We cut the sausage in half, but if you’re making this for kids, I’d cut the sausage into smaller pieces.
  3. Then we barely cooked the green pepper strips (optional) and layered that over the sausage.
  4. Rinse the cottage cheese and let it drain while you’re cooking the sausage.
  5. Then layer the drained cottage cheese, grated cheese and green onions, and pour the beaten eggs over those ingredients.
  6. Cook on low for 2 hours or slightly longer, until the center of the casserole feels firm and the cheese is all nicely melted.
  7. Things don’t brown in the slow cooker like they do in the oven, but sprinkling some green onions over the top will dress this up nicely.
  8. I like to eat this breakfast casserole with a dollop of sour cream; enjoy!

Slow Cooker Sausage and Egg Casserole

Prep Time 20 minutes
Cook Time 2 hours
Total Time 2 hours 20 minutes

When you need breakfast for a crowd, try this Slow Cooker Egg Casserole with Sausage, Peppers, and Cheese!

Ingredients

  • 1 1/2 cups cottage cheese, rinsed and drained
  • 2 12 oz. packages turkey breakfast sausage links (see notes)
  • 3 tsp. olive oil, divided
  • 1 green pepper, cut into thin strips (or diced)
  • 2 cups grated cheddar cheese (see notes)
  • 1/2 cup sliced green onions + 2 T more to sprinkle over at the end
  • 1 tsp. Spike Seasoning (or more, see notes)
  • fresh ground black pepper to taste
  • 14 eggs, beaten until yolks and whites are well-combined

Instructions

  1. Spray Casserole Crock Slow Cooker (affiliate link) with non-stick spray or mist with olive oil.
  2. Put cottage cheese into a fine mesh colander, place in the sink, and rinse with cold water until the creamy part is rinsed away. Let cottage cheese drain while you cook the sausage and peppers.
  3. Heat 1 tsp. olive oil over medium-high heat in a large frying pan and cook half the sausages until they’re well-browned.
  4. Put sausage on a cutting board to cool. Heat another tsp. oil, cook the second half of the sausage, and transfer it to the cutting board. (If you have a giant pan that can cook all the sausage at once, by all means use it!)
  5. Heat the final tsp. of oil and brown the green pepper strips about 2-3 minutes. (You can skip this if you like them slightly crunchy.)
  6. Cut the sausage into halves or fourths and layer them in the slow cooker with the green pepper strips.
  7. Sprinkle the drained cottage cheese and then the grated cheese over the sausages.
  8. Top with the sliced green onions and sprinkle with the Spike Seasoning (affiliate link) and black pepper.
  9. Beat eggs until they’re well-combined and then pour over the sausage, cottage cheese, and cheese. (I like to take a fork and slightly “stir” so the sausages and peppers are evenly distributed in the eggs.)
  10. Put the lid on and cook on LOW for 2 hours, or slightly longer, until the eggs are firm in the center and the cheese is nicely melted.
  11. Sprinkle with the rest of the sliced green onions and serve hot.

Notes

I used Jenni-O Turkey Sausage Links, but use pork sausage for this recipe if you prefer. Use any all-purpose seasoning that's good with eggs if you don't have Spike.

Making this recipe in a Six-Quart Oval Slow Cooker:

I haven’t made this in other sizes of slow cookers, but I can give some recommendations. (If anyone tries it, please let us know how it works.) I have made several variations of slow cooker frittatas in my Ninja, so I know you could make a recipe similar to this in an oval-shaped 6-Quart Slow Cooker. I would not recommend using a smaller size. 

  • 1 cup cottage cheese, rinsed and drained
  • 12 oz. lean turkey breakfast sausage links
  • 2 tsp. olive oil
  • 1 small green pepper, cut into thin strips (or use half a pepper if you prefer)
  • 1 1/3 cups grated cheddar cheese
  • 1/3 cup sliced green onion + 2 T more to sprinkle over at the end
  • 1 tsp. Spike Seasoning
  • fresh ground black pepper to taste
  • 8-9 eggs, beaten until yolks and whites are combined

Follow directions above to prepare the casserole for the slow cooker. The mixture will be a little thicker in a smaller casserole dish, so cooking time will probably be closer to 2 1/2 – 3 hours on LOW.
