An easy sausage casserole recipe with potato like slices of daikon radish. It’s a delicious casserole that’s low-carb, keto friendly, and gluten-free.
I wanted to serve my family an alternative potato dish this Thanksgiving. When I used diced daikon radish in a low carb clam chowder, I wondered how it would be in something like scalloped potatoes.
Since the Japanese daikon radish has very little flavor, I thought an additional item should be added to the dish. We have lots of venison sausage in the freezer so it made sense to use some with the daikon.
Although I was seeking a scalloped potato dish, the result was more like a casserole. That’s why I’m calling it an easy sausage casserole with mock potato.
I thought of calling the dish a sausage potato casserole, but that’s a little misleading. Although the radish does taste like potato, technically it’s not.
Sausage Casserole Ingredients
Here’s the list of ingredients used in the casserole:
- bulk ground sausage
- minced onions (dried or fresh)
- butter
- xanthan gum (low carb thickener)
- heavy cream
- coconut milk in carton (or almond milk)
- daikon radish
- cheddar cheese
- salt & pepper to taste
If you want more of a sausage potato breakfast casserole, the xanthan gum can be replaced with a couple eggs or more.
How to make sausage casserole with mock potatoes
While the oven is preheating to 350°F, the 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 prepared, about 1/3 of the cream sauce is spread at the bottom of a small casserole dish. Half of the peeled and thinly sliced daikon is then arranged on top. It’s best to use a mandoline slicer to get the radish sliced evenly.
Half of the cooked sausage mixture is then sprinkled over the top of the daikon slices. Next, half the cheese is sprinkled on top.
Then 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 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.
How to serve the sausage casserole
The sausage casserole can be served as a side dish since it’s a scalloped mock potato recipe with added meat. But it’s also hearty enough to be served as the main dish for lunch or dinner.
If serving the sausage potato casserole as the main dish, add in a side dish of steamed vegetables or a side salad.
Other ground sausage casserole recipes
I’ve got a couple other ground sausage casserole recipes on the site. My squash casserole adds in zucchini and summer squash and my paleo breakfast casserole is great for those avoiding dairy.
Whichever recipe you choose to make, you will have a yummy low carb meal. And, all of the recipe freeze well so you can save some for later.

Angie
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!
Lisa MarcAurele
Red radishes work too. I just prefer the larger daikon radish for this recipe.
Brenda
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!
Lisa
*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!
Lisa MarcAurele
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.
Susan Christie
Can I shred the Radish White Daikon like Hash Browns in this dish?
Lisa MarcAurele
That should be fine.
Melanie
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.
Lisa MarcAurele
Almond milk is fine to use in place of coconut milk in the recipe.
Renee
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 ?
Lisa MarcAurele
That should help if it wasn’t soft enough in the casserole.
Liz
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!
Lisa MarcAurele
You’re very welcome! I’m a big fan of turnips too.
Freda Davies
Loved it! Made scalloped ‘ potatoes ‘. Tasted great!
Lisa MarcAurele
I’m so glad you loved these low carb “potatoes”!
Jette
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.
Lisa MarcAurele
Hope he can’t tell the difference!
Patricia
Is there a sub that could use for the radish? Thanks
Lisa MarcAurele
You could try turnip, rutabaga, or cauliflower.
Kelly Mac
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… 😉
Lisa MarcAurele
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.
Emily Kemp
I’ve never heard of daikon either, interested to try it because this sounds so yummy!
Carolyn
I’ve never had daikon radish, but I will keep my eyes out for it, since it’s such a great low carb substitute.
