First, clean and rinse the cabbage heads. I like to soak them in a large bowl filled with cold water and 2 tsp salt. Leave them in the bowl for 10 minutes
Then, peel the carrots and the onion and grate them. I used a knife to cut them into pieces and grated them with the Thermomix for 5 SEC – SPEED 5
Now, I cut sections of the cabbage heads with a knife and grated the cabbage using the CHOP program of the Thermomix for 6 SEC. You can simply use a vegetable mandoline to finely chop the cabbage heads
Select the BROWN/ SAUTEE program of the Crockpot Express Multicooker for 10 minutes
Once heated, pour the vegetable oil
Add the grated onion and carrots and season them with salt, black pepper and sweet paprika. Mix occasionally
After the 10 minutes, add the finely chopped cabbage and the tomato juice. Mix well
Add water until you fill the pot and place a sprig of dried thyme on top
Close the lid and cook the keto cabbage soup recipe using the Slow cooking program, on HIGH temperature, for 3 hours 30 minutes
After this time, use a bowl to mix well the egg yolks and the sour cream
Open the lid of the Crockpot and remove the thyme sprig
Pour the egg yolks mixture over the hot soup. Use a ladle to incorporate the mixture in the hot soup
Close the lid and leave the flavors to combine perfectly for at least 10 minutes before serving the hot soup
Serve the hot soup with extra sour cream or with a hot chili pepper
