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.
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)
- 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.
