There are a lot of 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. And this type of egg casserole frees up the cook for a little over 2 hours while it cooks in the slow cooker, or until the eggs are firm and the cheese is nicely melted. 

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 for this recipe?

  • olive oil, divided

How to make this recipe:

(Scroll down for complete printable recipe, including nutritional information.)

  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.

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. I like it with a dollop of sour cream; enjoy!

Slow Cooker Sausage and Egg Casserole

Yield 10 servings
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!


  • 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


  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.


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.

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

I haven’t made this in other sizes of slow cookers, but I think I can still 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 or the 6-Quart Ninja Cooker. I would not recommend using a smaller size. The frittatas I’ve made in the Ninja cooker only served 6, so I would recommend cutting this recipe down as follows:

1 cup cottage cheese, rinsed and drained
12 oz. lean turkey breakfast sausage links
2 tsp. olive oil
1 small green pepper, but 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.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
If you’re making this Slow Cooker Sausage and Egg Casserole for the original South Beach Diet, it would be approved for all phases if you use lean turkey sausage (like I did) and reduced fat cheese. For other types of Low-Carb diets, you might want to use pork sausage and full-fat cheese. This recipe should be suitable or easily adapted for most types of low-carb eating plans.

  1. Hi Kalyn, l made a small version of this casserole in the oven this morning and it was delicious. I used 1/2 the amount listed for each ingredient and baked it in a 8×8 dish for approximately 30 minutes- it came out perfect.  I will definitely be using this recipe again and again- like I do so many of your others! 

  2. So glad to have found this recipe. My husband bought ten 16 oz cartons of cottage cheese because there was a sale. Well, at least it wasn't 100 lbs of white potatoes! The draining of the cottage cheese just makes so much sense. Printed it and gathering up the ingredients right now. Thanks for sharing this recipe with us. Sharon

    • I hope you enjoy Sharon! That sounds like a challenge to use that much cottage cheese! You can enter "cottage cheese" into the search bar and find other recipes that use it.

  3. what could i use instead of cottage cheese? dairy is sometimes a problem for a friend of mine. would tofu work?

    • Sarah, I can't say for sure because I've never used tofu in a recipe like this. But I think it might work. The cottage cheese kind of melts like cheese into the eggs, and the tofu won't do that, but the flavor will probably be okay.

  4. I don't own a crock pot for this. how would I bake it in the oven?

  5. Love your site, love your recipes. Gotta tell you – this one was amazing! I never thought eggs could turn out good in a slow cooker. Most of the recipes I currently use for South Beach are from YOU! 🙂

    • Marcia, so glad you enjoyed it. I am definitely a convert to the idea of eggs in the slow cooker. And glad my recipes are helpful for you! I love hearing that.

  6. This would be great for holiday morning brunches. Also, I haven't seen this type of slow cooker before — how cool! I don't make many casseroles, but it would be so handy if I did.

    • Thanks Sarah! I had it in mind for holiday mornings, this reheats well so you could also make it to keep in the fridge for the week. That's what I did!

  9. I love breakfast casseroles and this one sounds so good! I've never seen one of these casserole crockpot slow cookers before! What an awesome tool!

  10. I had no idea this casserole slow cooker existed but I'm loving the concept. I'm all about casseroles and Crock-Pot meals so why not comibne them? This is a great breakfast dish for when you've got a house full of guests. Great idea!

  15. I've been really getting into my crockpot lately, and I've never heard of this version before…so neat! Love the idea of throwing everything together and letting the crockpot do the hard work while having a lazy family morning 🙂

  16. That casserole slow cooker sounds magic! What a wonderful breakfast dish for any time of the year (but you're definitely right about Christmas morning).

    • Thanks Dara! I am really loving the Casserole Crock Slow Cooker. (And I didn't dare mention the C word, but I couldn't help but think it would be perfect for that.

  17. This is definitely a great idea for a brunch party! It's great to have the stovetop free for making other parts of the meal.
