Why Is Cauliflower Soup Good For You?

Cauliflower is naturally low in carbohydrates and even lower in net carbs thanks to its high fiber content. Not only is it low in carbs, but it’s also low in calories. If you’re living a low carb lifestyle, cauliflower soup is an excellent way to get a filling and flavorful meal without going over your macros for the day.

Ingredients You’ll Need

Cauliflower- Keep the chunks of cauliflower relatively large. Around 3" pieces is best for this recipe to keep the texture of the cauliflower from becoming mushy when cooked under pressure. Onion- Don’t dice it too thin. Cut it into thick pieces about 2" wide.Carrots, turnips, or potatoes- If you’re wanting to keep this soup low carb, opt for turnips instead of potatoes. You will also want to cut these into thick pieces.Canned Tomatoes- I prefer diced tomatoes for this recipe so you get a little in every bite. You can also use quartered or tomato halves.Sambhar powder- a tasty blend of spices often found in Indian cuisine.Kosher SaltTurmeric

How Do You Make Instant Pot Cauliflower Soup?

The most important thing to note here is that you are cooking this Cauliflower Soup under LOW PRESSURE. Many Instant Pot Soups call for cooking the ingredients under high pressure, but to ensure the cauliflower isn’t overcooked, you’ll want to hit the low pressure button for this recipe.

What Is Sambar Powder?

Sambar powder is a common spice used in Indian cooking. It’s a mixture of spices like cumin, coriander, mustard and fenugreek, and more that are ground together into a fine powder. There are different blends for this, but they all have a similar flavor profile. A typical sambhar has lentils in it and you can find a Sambar recipe. But this is a quick way to get a delicious sambhar-like flavor without a lot of work.

What Can I Substitute For Sambar Powder?

The best tasting Sambar is made. If making spices intimidates you, it shouldn’t! It’s so simple to make your own, and you will be blown away by the difference in taste. This is my Sambar powder recipe, and I highly recommend trying it at least once.

What If I Don’t Want It To Be Spicy?

Simple! When you make your sambar powder, just leave out the chilis! You’ll still get all of the rich flavors from the spice blend without the heat.

Does The Instant Pot Make This Cauliflower Soup Mushy?

Nope. Instant Pot cauliflower recipes have a tendency to be overcooked, that’s why I tested this one until it was perfect. I can’t stand when cauliflower turns into a soft mush. Cooking it using this recipe actually gives the cauliflower a really good texture. It’s cooked all the way, but still maintains the texture of the cauliflower florets.

How Do You Thicken Cauliflower Soup?

This soup is meant to be a brothy soup, but if you’re wanting to thicken it up a little, simply remove half of the cooked cauliflower from the Instant Pot liner and use an immersion blender to blend up half of the soup ingredients. The cauliflower, tomatoes, and turnips (or potatoes and carrots if you’re not keeping it low carb) will create a thick, rich soup base when blended.

Can I Freeze It?

Absolutely. It’s common for me to make a big batch of this, and then freeze it in one-serving containers for when I want soup, but don’t want to cook. It’s so much better than canned soup!
