ingredients

1 pound bulk breakfast sausage
prepared mustard, as needed
14 slices bread
2 1/2 cups grated cheddar or monterey jack cheese
12 eggs
2 1/4 cups milk
1 teaspoon salt
1 teaspoon black pepper

directions

Heat a skillet over medium-high heat. Add the sausage and cook, stirring frequently, breaking up the meat and cooking until it is browned. Drain off any excess grease.

Grease the inside of the crock pot well. Spread mustard on one side of each of the bread slices. Cut the bread into quarters.

Place a layer of bread in the crock pot. Top with a layer of sausage and a layer of cheese. Repeat the layers, ending with a layer of cheese.

Beat the eggs, milk, salt, and pepper in a bowl until well mixed. Pour the egg mixture slowly over the layers in the crock pot.

Cover the crock pot and cook on low heat for 3-4 hours or until the casserole is set.

Serve the sausage and egg casserole hot.


crock pot notes

Crock pots/slow cookers all heat differently. There is no standard among manufacturers. Cooking times are suggested guidelines based on our testing. Please adjust cooking times and temps to work with your brand and model of slow cooker.

recipe tips


Cook the sausage thoroughly until it's no longer pink.

Cut the bread into even pieces for uniform cooking and texture.

Layer the ingredients evenly to distribute the flavors throughout the casserole.

Whisk the eggs and milk thoroughly for a smooth, even custard.

Pour the egg mixture slowly to allow it to soak into the bread layers.

Let the casserole rest for a few minutes after cooking for easier serving.

Season the egg mixture well to ensure the casserole is flavorful.

Experiment with different seasonings like paprika or garlic powder for added flavor.

common recipe questions


What type of sausage is best for this casserole?

Bulk breakfast sausage, either mild or spicy depending on your preference, works well for this recipe. But you can use any bulk sausage including turkey sausage.

Can I use any type of bread?

Yes, you can use any type of bread. Day-old bread works particularly well as it absorbs the egg mixture better.

What can I use instead of mustard?

If you don't like mustard, you can omit it or use a light spread of mayonnaise or cream cheese for added moisture.

Can I add vegetables to this casserole?

Yes, adding vegetables like bell peppers, onions, or spinach can add flavor and nutrition.

Is it necessary to grease the crock pot?

Yes, greasing the crock pot prevents sticking and makes serving and cleanup easier.

Can I prepare this casserole ahead of time?

Yes, you can assemble the casserole the night before, refrigerate it, and start cooking it in the morning. Allow for extra cooking time.

How do I know when the casserole is done?

The casserole is done when the casserole is firm.

Can I cook this casserole in the oven instead of a crock pot?

Yes, you can bake it in the oven in a deep baking dish at 350 degrees F for about 45-50 minutes.

What cheese works best in this recipe?

Cheddar or Monterey Jack cheese is recommended, but you can use any cheese that melts well.

reviews & comments

  1. mysterious one REVIEW:

    I agree. 6 hours on low is all it needed. Glad we were flexible with what time we ate. It was very good. I topped it with some cooked crumbled bacon too.

  2. Kat REVIEW:

    I'm glad I checked on this when I did because it was ready in 6 hours in my crock pot. Made it as directed. Very good, but we ended up eating early.

  3. Soxy REVIEW:

    I used breakfast sausage links that I cooked and then chopped up since I didn't have any bulk sausge on hand. Easy recipe to make with normal ingredients.

  4. Lizzie REVIEW:

    The first time I made this I skipped the mustard step as it sounded like extra work. The eggs were good but just ok. After that I tried the mustard and it really helped zip up the recipe.

  5. Leslie REVIEW:

    12 hours would be way too long for this so keep it under 8. It's good, could use something like nutmeg unless you use spicy turkey sausage or maybe spicy cheese.

  6. sbel8653

    Is there a way to cook this, if You only have off/on on cooker, how do you tell if it is done?...and can this be done in the oven? I really want to make this, it sounds delicious...

  7. SiliconKnight REVIEW:

    I bought a new crock pot and tried this for a work potluck. It was WONDERFUL! I scaled it up a bit (18 eggs, 2lbs sausage, ~2lbs cheese, etc. - fit perfectly in my 6qt oval), and put it in at 10pm using the probe set for 160 degrees. By 6am it was done and had automatically shifted to warm. The internal temperature was ~180 or so, I let it coast with the crock pot off for 30-45 min (temp never dropped below 160). Plugged in at work on the WARM setting and it was a HUGE hit. No crust on the bottom or sides, no sticking to the pot (I did grease with shortening), and only slightly brown. Will definitely make this again. Thanks!

  8. Cookitnow REVIEW:

    I really liked this recipe. I noticed the other reviewers' comments about the casserole being overdone. I had that happen previously with a different recipe in my newer crockpot. So I took out my trusty, 20-year-old crockpot for this one and it worked perfectly. I cooked it for about 9 hours. Also, I used 9 slices of toasted whole wheat bread instead of the 14 in the recipe (because that's all I had!). Received lots of compliments from coworkers! Also added just a little bit of sour cream because I wanted to use it up.

  9. SloopyCain REVIEW:

    Pretty good! I use 23 eggs, substituted the milk for water, added spinach and tomatoes in the layers and some hot pepper. It was great and easy! Feed the 4 of us for 3 meals!

  10. meyerdo

    Thinking of making it a 4 serving but first would like to know - what size slow cooker for 6 servings? Thanks

  11. barbara REVIEW:

    The best casserole breakfast that I have ever had, the taste is great and easy to make. Thanks for this!

  12. Enzo's Mom

    I'm not the best cook...and I really thought this one was impossible to screw up. I started the crock pot at 9pm and by 5:30am the edges were burnt to a crisp. I tried the center part and there was nothing worth salvaging. What went wrong?

    • Crockpots heat differently depending on brand, model and even the age of the unit. Many of the newer crockpots way overcook foods. I have one that I have to use the "low" setting for any recipe calling for high heat, and the "warm" setting for ones calling for low heat otherwise recipes don't turn out right.

  13. Joisey Kathy REVIEW:

    Someone made this for a party at work. IT WAS AMAZING!! She did say it didn't take quite as long to cook as the recipe indicated but that might be because a different crock pot was used. When I make it, I am going to try adding some red peppers and onions. I'll watch it close to see how long it takes. TRY IT, YOU WILL LOVE IT!!!

  14. CrockPot Grrrl REVIEW:

    I substituted: Egg Beaters, Non-Fat Milk, 2% Cheese, Jimmy Dean Precooked Turkey Sausage Crumbles and used Pam Spray for a much healthier version of this. We didn't miss the fat. VERY GOOD!!!

  15. Media maven REVIEW:

    I also added a small can of mushrooms, and fresh green and red pepper slices for added flavor and color. cooked overnight on low from midnight- 7 am and turned out fine. great recipe if you'd like a hearty breakfast without the fuss and delay in the morning.

  16. Guest Foodie REVIEW:

    This recipe tasted great and was easy to prepare! My husband loved it too. Used 6 person recipe and cooked it on low for 8 hours and it was perfect and browned. Highly recommend.

  17. Sue

    Earlier today I sent in a review that rated this recipe as 1. I found out from the person who took this casserole to her brunch that after 8 hours, it was good. However, she left it on low during the brunch (about 4 more hours), and after that it was very dry and burned on the bottom and edges. You could just delete my previous comments.

  18. Sue

    I think it would be good to give a definite time rather than 8-12 hours. I served this after 8 hours in the crockpot. The sides were burned, and the mixture was very dry. I did substitute pork sausage for turkey sausage, but I don't think that would affect the cook time

    • Unfortunately, these days all crockpots heat differently so a time that works for one brand/model may not work for another. All the slow cookers/crockpots used to be consistent but a few manufacturers changed things and now you have to make a lot of adjustments to recipes to get them to work for you.

  19. lyndy REVIEW:

    Fantastic -- 15 minutes to prepare than just let it go over night. We brought it to a church potluck and received nothing but compliments. The only thing I will differently next time is go about 10 hours instead of 12. It was still very good but there was a bottom crust stuck to the crockpot.

  20. belfle REVIEW:

    i brought this to work for a potluck and it was way overdone, we ate the middle out of it and it was really good, what we could eat. i'll make it again but prob try 3-4 hours instead.

    • Certain models of newer crockpots (last 5 years or so) overcook foods so most recipes you'll find online need to be adjusted occasionally. It's a shame the manufacturers won't fix their product to work the way the rest of the slow cookers operate.

  21. MichiganMeg REVIEW:

    We made this recipe as-is, with the exception of mixing spicy brown mustard into the egg mix instead of putting onto the bread slices. This smells wonderful while it's cooking--it actually woke me up--but 8-12 hrs is WAAAAY too long for this dish! We have the large circular WestBend crockpot, and after 7 hrs on low, we had to cut the burned edges off, scrape out what we could from the inside, chop it up in a separate dish and add lots of extra cheese before serving. It seemed that we might have done better just making a do-ahead strata and baking it that morning. The flavor of this recipe is good, but the cooking time really needs to be adjusted! Good luck!

    • Unfortunately, crock pots no longer all heat equally so a recipe that may work perfectly for one person's brand/size crock won't always work for another. It's a shame that the manufacturers are not working harder to correct this.

  22. Guest REVIEW:

    This is a great recipe! I made this casserole for a brunch and everyone LOVED it! I added canned/chopped mushrooms in with the sausage layer and I also added about 4 more eggs with a little milk to cover the top more evenly (I have a large crock pot). One thing to note...this recipe only took 5 hours on low to cook, not 12 like the recipe says! Very, very good!

  23. brown1183 REVIEW:

    this is an easy recipe to make...it does NOT take 12 hours to cook. min eonly took about 3 hours. it is very good!!!!
