For an absolutely delicious comfort dish the whole family can enjoy, this easy keto sausage casserole is hard to beat! It combines ground meat with mock potato slices in a buttery cream sauce.
You are going to love this easy keto breakfast recipe! It combines ground pork sausage with daikon radish slices and plenty of shredded cheese.
The radish tastes so much like potatoes that I thought about calling it a sausage potato casserole, but that's a little misleading. Although the radish does taste like potato, technically it's not.
No matter what you call it, this low carb breakfast casserole is sure to please even the pickiest eaters. In fact, I served it to my family and they didn't even suspect it was a dish low in net carbs.
Let's take a look at what you need to make this keto breakfast casserole with sausage.
Here's the ingredients you'll need for the recipe:
- Bulk ground sausage - It's best to use a ground pork breakfast sausage. But you can change up the flavor for lunch and dinner by using Italian sausage.
- Minced onions - Either dried or fresh can be used. I tend to use dry minced onion as it's always in my pantry.
- Butter gives a nice buttery flavor to the sausage breakfast casserole.
- Xanthan gum is a low-carb thickener used to thicken up the cream sauce.
- Heavy cream adds flavor and creaminess to the sauce.
- Keto milk is any milk that is low in carbs. I like to use coconut milk in the carton but unsweetened almond milk is another great option.
- Daikon radish is one of the best keto potato substitutes. But if you can't find it you can use another mock potato like cauliflower, turnip, or rutabaga.
- Cheddar cheese is my favorite shredded cheese to use. However, feel free to use your favorite type. Monterey jack cheese is a good alternative.
- Seasoning - I just use a little salt & ground black pepper to taste but a little garlic powder is a nice add.
If you want more of a traditional keto breakfast casserole, the xanthan gum can be replaced with a couple eggs or more.
Just follow these step-by-step directions to make the gluten free breakfast casserole.
Preheat oven then cook sausage while the oven is warming up. ground sausage is cooked with onion in a large skillet.
To save time, the sauce can be prepared while the meats cooks. The creamy sauce is a made by blending melted butter with cream, low carb milk, and xanthan gum.
Once the sauce is prepared, about ⅓ of it is spread at the bottom of a small casserole dish. Then half of the peeled and thinly sliced daikon is then arranged on top.
Half of the browned sausage mixture is then sprinkled over the top of the daikon slices.
Then, half the shredded cheddar cheese is sprinkled on top.
Next, another third of the cream sauce is spread over the cheese layer. The layers are repeated ending with the remaining third of sauce drizzled over the top.
After assembling all the layers of the sausage breakfast casserole, the baking dish is covered with foil. It's than baked for 30 minutes at 350°F.
The foil cover is removed after the initial 30 minute baking time. Then the casserole is returned to the oven to bake for an additional 25-30 minutes. At this time, the top should be browned and the radish should be tender.
- Cut radish into slices with the same thickness. It's best to use a mandoline slicer to get the radish sliced evenly.
- Use eggs. For more of a breakfast casserole, replace the xanthan gum with 2-4 eggs.
- Change the sausage. Pork breakfast sausage is preferred when serving this as a keto breakfast. But other types of sausage can be used, especially if serving for lunch or dinner.
- Add cream cheese. For a little bit of tang, stir in some softened cream cheese into the cream sauce. It's also a great thickener so you can omit the xanthan gum.

This recipe looks amazing. Can't wait to try it. What size baking dish are you baking this in?
It's a medium oval size, about 1 1/2 quarts.
This looks great and I'll definitely give this a go! I'll also try using this recipe as a basis for a gratin dauphinoise for Christmas!
Also, thanks for saying 'mock' potato in the recipe description! Refreshingly straightforward!! 🙂
Made this for dinner tonight. I cooked it for over an hour (1 hour 20 minutes!) and the Daikon Radish still wasn't soft! If I ever use daikon again, I will boil them a bit before I use them in baking. Recipe overall was just meh. I think 1 tsp of Xantham gum was too much and may have contributed to the daikon not cooking. If I make this again, and I probably won't, I will only use 1/4 tsp xantham gum.
If the daikon is sliced thin, it should not take that long to cook. The amount of xanthan gum shouldn't impact it either.
I can't find daikon radishes where I live anywhere. Can red radishes be substituted? Thanks in advance and thank you for all the great recipes!
Red radishes work too. I just prefer the larger daikon radish for this recipe.
Daikon is genius! This was a delicious recipe. I used chicken sausage in ours yesterday. Made corned beef hash with daikon this morning and then a seafood chowder with daikon for supper tonight. Awesome potato hack!
*Loved* this recipe, and so did my husband! I've enjoyed using cauliflower as a substitute for potatoes and for pasta, and it's close in many dishes, but this was like eating sliced potatoes. Might daikon work for 'potatoes' au gratin? Potato chips? French fries? We're going to find out!
I haven't tried fries, but it works well for au gratin. The chips should work out. Sometime, I just slice the daikon and use it raw like a cracker.
Can I shred the Radish White Daikon like Hash Browns in this dish?
That should be fine.
Can the I use almond milk in place of the coconut milk? I have people in my family that do not like anything with coconut.
Almond milk is fine to use in place of coconut milk in the recipe.
Can I boil the radish for a few minutes first? I made this but the radish was still a bit crunchy after baking. I was still excellent!?making again today ?
That should help if it wasn't soft enough in the casserole.
Made this last night for the hubs and our nephew. They both thought it tasted more or less like a potato casserole, i used turnips, but actually better because turnips have that little bite. Thank you for the recipe!
You're very welcome! I'm a big fan of turnips too.
Loved it! Made scalloped ‘ potatoes ‘. Tasted great!
I'm so glad you loved these low carb "potatoes"!
To-night we are having Scallopped Dicon and New Yorker steak. My husbund is not on Keto but he likes my dishes. He is a real potato and gravy man, but I can fool him. I hope this is one of the recipes that helps me with that. I will let you know to-morrow. I lost 35lb on Keto the last 11 mds.
Hope he can't tell the difference!
Is there a sub that could use for the radish? Thanks
You could try turnip, rutabaga, or cauliflower.
Looks delish and look forward to trying! Wanted to let you know Pinterest is giving an error msg when trying to Pin your pix for this dish... 😉
Thanks for the head's up. I think it's because the images are loading a bit differently. The pin button at the top and the pin in the recipe card are working for me.
I've never heard of daikon either, interested to try it because this sounds so yummy!
I've never had daikon radish, but I will keep my eyes out for it, since it's such a great low carb substitute.
