Keto Slow Cooker Sirloin Steak Soup

Keto Slow Cooker Sirloin Steak Soup


When I woke up this morning, I discovered that our deck was covered in a bit of snow. It’s only mid-October. What’s it like where you are? Do you like fall or winter, or miss summer already? I’m a bit more indifferent these days, since I work from home. However, with this weather, I’ll be focusing even more on comfort foods. Due to the cold, I created a keto sirloin steak soup today, which is both comforting and also has a slight kick, to warm you up. As a bonus, radishes were included – which in the keto world, tend to mimic potatoes!

My husband classified this soup as, “The best soup I’ve ever made for him.” It is filling, packed with vegetables, super creamy, and very flavorful! As a very added bonus, this steak soup can be made in a slow cooker/crockpot. It doesn’t get much better than that! It’s delicious and it requires very little effort!

If you decide NOT to use a slow cooker, you’ll probably want to add more bone broth, about 1/2 cup more, to ensure you have enough liquids. However, I do recommend using the slow cooker, if at all possible!

You’ll notice the meat in this soup is done after about 3 hours on high. Really, anything done past this is a matter of bringing out the flavors further. Trust me on this, you can follow the steps and still have tender meat (and vegetables). Also, you will end up with a very comforting soup!
