All items are tools or ingredients I have used myself or I wouldn’t recommend them to you!

We are just rolling into December as I write out this recipe and it’s already sooo cold outside. And while I’ve got the fire blazing it doesn’t quite take the chill away. I basically want to eat soup every single day for lunch and dinner, and while that is all fine and dandy with my family, I just don’t have the time to watch a pot of soup simmer away all day long. I’ve got big important things to do every day! 😉

If you’re a busy mom like me, or work 🤣, then you must know my excitement when I found out about the instant pot and all it’s amazingness? Make a delicious soup that tastes like it’s been simmering all day long in less than an hour? And make the entire thing in one single pot?! SOLD!

I usually make this Low Carb Chicken Taco Soup in my slow cooker, which is super easy as well, but there’s nothing better than getting home at 5pm after a long busy day of toteing children around, and having a yummy soup made from start to on the table at 6pm.

I LOVE my new instant pot and look forward to blasting out some new recipes to you lovelies 🙂

Why it works

  1. This Instant Pot Low Carb Taco Soup is super flavourful, the texture is epic and there are so many yummy toppings to choose from! Yay for toppings!
  2. Thanks to the Instant Pot, this delicious soup is ready in 50 minutes from start to finish!
  3. Chicken Taco Soup is easily transformed into this low carb version, beautifully garnished with cheese crisps instead of nacho chips.

Ingredients

Think… chicken tacos and soup collide!

  • boneless skinless chicken breasts
  • onion
  • red pepper
  • jalapeños
  • garlic
  • diced tomatoes
  • tomato paste
  • bone stock or chicken broth
  • chili powder
  • paprika
  • cumin
  • oregano
  • sea salt
  • toppings of choice

Boneless Skinless Chicken Breasts – You can buy these with the bone in and skin on to save a few bucks, like I always do, and remove the bone and skin yourself! Never done it before? Check out this video to learn how.

Bone Stock or Chicken Broth – Yes, you can buy chicken broth from the store, but if you have time, make your own! Check out this How to Make Bone Stock post or use your Instant Pot to make some Instant Pot Chicken Broth! Another excellent way to get some flavourful juice into this Low Carb Chicken Taco Soup? Use the leftover juices from these Instant Pot Pork Carnitas.. omg SO TASTY!

Toppings – tex mex shredded cheese, avocado, raw diced tomatoes, green onion, sour cream, raw diced peppers or cheese crisps. See further down the post to learn how to make cheese crisps.

How to make Low Carb Chicken Taco Soup in and Instant Pot

Turn your Instant Pot to saute and once hot, add 1/2 tbsp of avocado or olive oil. Dice up an onion and a red bell pepper and add them to the hot pot. Cook until the onion in translucent, then scrape out into a bowl and set aside.

While the onions are cooking, mix up the herbs. Press or mince the garlic and add to a small bowl with the chili powder, paprika, cumin, oregano and salt. Massage the rub into the chicken breasts.

Once the onion and pepper have been removed, add another 1/2 tbsp oil to the Instant Pot. Once hot, sear both sides of the seasoned chicken breasts, then remove from the Instant Pot and shut it off. While the chicken is searing, chop up the jalapeños. If you don’t like a spicy soup, be sure to remove all the seeds or it’ll be super spicy. 

Deglaze the instant pot by pouring 1/2 cup of the bone stock or chicken broth in and scraping away all the little bits away from the bottom of the pot with a wooden spoon.

Add the chicken back into the broth and, without mixing, dump the remaining ingredients on top of the chicken in this order: onion and red pepper, chopped jalapeños, diced tomatoes, tomato paste and lastly the remaining bone stock or chicken broth. Again, do not mix.

Secure the lid of the instant pot and turn the valve from venting to the sealed position. Cook on the Pressure Cook setting for 25 minutes, naturally release for 5 minutes, then carefully, quick release.

Once all the steam has been removed, open the lid to the instant pot. Remove the chicken and mix the shredded tex mex cheese into the soup. Use two forks to shred the chicken into chunks and place back into the soup. Mix and serve immediately!

Expert Tips

  1. Be very careful when working with jalapeño peppers. The juices can burn your skin, so I recommend using gloves when touching them while dicing. If you get some juice on your skin, wash with olive oil before washing with soap and water.
  2. How spicy do you like it? If you do not want a spicy soup, discard all of the jalapeño seeds. If you do like it spicy, add them all!
  3. Make sure to deglaze the bottom of your instant pot well, otherwise the BURN message will want to display and ruin your day.
  4. I know it’s hard, but don’t mix the ingredients together before they have gone through the pressure cooking stage. This is another way you could get the BURN message. Tomato paste and diced tomatoes are super thick and can easily stick to the bottom of the pot.
  5. Be sure the steam release valve is set to the correct sealed position, other wise the Instant Pot will not come up to full pressure, meaning your soup won’t cook!

How to make Cheese Crisps

I LOVE me some cheese crisps 😋 They are crazy easy to make and are sooo yummy! I make them to dip into my Low Carb Hot Bean and Cheese Dip, I replace croutons for these in my Low Carb Kale Caesar and they are simply magnificent in place of tortillas in this Low Carb Chicken Taco Soup. Heres how you can make your own cheese crisps:

Heat oven to 350° and line a baking sheet with a non stick baking mat or parchment paper. Place 1/4 cup shredded tex mex cheese in a low raised mound on one side of the baking sheet and a second mound on the other.

Bake for 8 – 10 minutes in the preheated oven. You want them to look super crispy otherwise they will be soggy once cooled. Remove right away from the pan and place on paper towel to cool for a minute or two – yes they will be super pliable.. for now..

After they have cooled for a minute or two, slice them into long strips before they cool completely and turn hard and crispy. Garnish your soup with these yummy tex mex cheese crisps!

How to make Low Carb Chicken Taco Soup in a Slow Cooker

Don’t have an instant pot? No worries! Here is how to make this yummy Low Carb Chicken Taco Soup in a slow cooker:

Heat a skillet over medium heat and add 1/2 tbsp of oil. Once hot add diced onion and diced red bell pepper and cook until the onion is translucent. Scrape the onions and peppers from the skillet and add another 1/2 tbsp of oil.

Mix the rub ingredients together and massage into the chicken breasts. Once the oil is hot, sear the chicken breast, both sides, then remove from the skillet.

Deglaze the skillet with 1/2c bone stock or chicken broth to get all the yummy flavours from the chicken. Dump into the slow cooker and add the remaining broth, chicken, onions and peppers, diced jalapeños, diced tomatoes and tomato paste.

Cook on high for 3-4 hours or low 5-6.

Remove the chicken from the slow cooker and mix the shredded tex mex cheese into the soup. Use two forks to shred the chicken and place back into the soup. Serve hot with your choice ingredients.
