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.
