This soup comes together quickly, with just a few simple steps, yet tastes like a high-quality restaurant meal. It's beautiful, rich color and creamy consistency take the experience to the next level.

Carrots

Carrots might not typically be the most exciting vegetable, but in this recipe they’re the star. They bring vibrant color and a hint of sweetness that makes this soup shine.

Carrots are known for supporting eye health. This is due to their beta-carotene content, which your body converts into vitamin A. But Vitamin A is not the only component in carrots that benefits your vision. Lutein is a specific carotenoid that accumulates directly in the retina and acts as a sunglass lens for your eyes, protecting you from macular degeneration.

Cauliflower

Cauliflower is a very versatile vegetable. You’ve probably seen it turned into rice, pizza crust, buffalo wings, and all sorts of other foods. In this recipe, we’re just turning it into soup – but we’re still utilizing some of its best features! When steamed and blended, cauliflower takes on a creamy consistency that adds depth and comfort you’ll love.

Like other cruciferous veggies (broccoli, cabbage, kale), cauliflower is rich in glucosinolates, which break down into sulforaphane — a compound that supports liver detox enzymes, helps clear out excess estrogen and toxins, and has anti-cancer and anti-inflammatory effects. Cauliflower’s non-starchy fiber also feeds your gut microbiome and supports healthy digestion.

Potato

Potatoes are a widely misunderstood vegetable, and today we are going to clear their name and give them the credit they deserve!

Potatoes get a bad reputation because they are often eaten in the form of french fries and chips. But when you skip the fried-in-oil step and eat them in their whole food form, potatoes are one of the most satisfying, blood-sugar friendly, and nutrient dense foods around.

First of all, potatoes score #1 on the satiety index – meaning that when you eat potatoes, they keep you fuller for longer. They score higher than rice, pasta, and even high protein foods like meat and eggs. This reduces cravings and supports your weight loss goals.

In addition, when potatoes have been cooked and then cooled (think: leftovers!), they develop what is called resistant starch, which improves insulin sensitivity and reduces blood glucose spikes.

We know you already love potatoes so go ahead and let yourself really love them! Starting with this soup.
