leek cauliflower soup

I hope you all had lovely holidays! My Christmas was fabulous. I could watch my girl for hours opening her presents. Such a great time. I know that all you want to read is what makes this soup so great to detox your body. I am sorry if I first need to share with you my feelings today. Tomorrow is a big day for me. I will finally meet him — my baby boy. After 38 weeks, I have been scheduled for a C-section to bring Luka to the world.

I am very excited and so scared too. Some people think that a C-section is ‘easy’ compared to natural birth. I don’t think there is an easy way to give birth. Birth is always a scary process as we never know what can happen, what we expect! Anyway, that is my last live post on the blog. I will keep feeding the blog during the next 4 months with recipes I wrote in advance for you. Today, I am sharing another yummy soup that  I planned to freeze and eat as a light dinner after the baby is born.

Leek Cauliflower Soup – my secret to a flavorsome low carb soup

I love this simple leek cauliflower soup. Especially because it’s light and doesn’t use any starchy vegetables. My secret for a tasty soup with low carb vegetables is to roast them first with shallots, garlic, olive oil, and spices. It’s a straightforward step that adds lots of flavor to any low carb soup. I love to use vegetable stock as a base for this soup, but chicken stock is a great option, too. Leek and cauliflower are both very low-carb vegetables.

They contain very few calories as well, and they are both amazing sources of fibers, vitamins A and C. Check out my keto vegetable list for a review of all common vegetables! The texture is not very thick or creamy. It’s a light soup with lots of spices flavor, perfect for a light family dinner. I drizzle virgin olive oil on top of my bowl. Emma loves to add grated mozzarella. I guess all kids love melted string cheese in their soup, and it’s a good source of calcium for them.

Instructions

  • Preheat oven to 180°C (350°F).
  • Spread the chopped vegetables: leek, cauliflower, onion, onto a baking tray in a single layer.
  • Drizzle the olive oil onto the vegetables and toss everything together until the vegetables are well coated.
  • Roast vegetables for 20-30 minutes, tossing vegetables every 5-10 minutes. The vegetables must be tender enough to be blended after the roasted process.
  • Meanwhile, pour the vegetable stock with thyme and salt into a large pot (must fit all your vegetables!) and bring to a simmer.
  • Once vegetables have roasted through, place them into the pot with stock.
  • Add in heavy cream and sour cream.
  • Blend with an immersion blender until it forms a creamy smooth soup. Adjust the quantity of stock to reach the desired consistency. The more stock you add, the more liquid the soup will be.
  • Serve with 2-4 tablespoons of grated cheddar per bowl or a simple drizzle of olive oil and fresh herbs.
  • Store up to 3 days in the fridge or freeze for later in airtight containers. Always wait for the soup to reach room temperature before packing in freezing boxes.
