Do you love eating soups? If you do, you’ll love this Keto Chicken Fajita Soup recipe using an Instant Pot.

Soup is important. It contributes to your liquid intake – the liquid base of soup helps to rehydrate. It also pairs vegetables and broths, seeds and juices, nuts and creams.

Soup consumption makes your diet balanced and varied. It serves as an instant source of fuel and helps repair your muscles. A soup is for workaholics – it promotes post workout recovery. With healthy liquids, your body absorbs vitamins and nutrients quicker, and boosts energy and activity.

Soup is always a fun creation. You can add new ingredients even to your traditional recipes. Soup welcomes leafy green vegetables – a storehouse of antioxidants and vitamins – and makes it easier for even the pickiest of eaters to get more greens in their diet.

My Keto Instant Pot Mexican Chicken Fajita Soup contains all of the low-carb vegetables and spices you would find in a traditional fajita recipe, such as bell peppers, tomatoes, chili flakes, garlic, onion, cumin, oregano, paprika, parsley, and more. 

Bell peppers are an excellent source of vitamin C, which is a water-soluble vitamin that is not produced in the body, meaning that we need to constantly supply it through dietary means.

Vitamin C helps keep your immune health working properly. It also aids skin and hair health through the production of collagen, as well continuously flushing toxins from the body to reduce the risk of disease and DNA damage. 

Bell peppers also contain a good amount of fiber, which – along with the protein in the chicken – helps keep you full and satisfied for hours, reducing your total calorie intake for the day and promoting weight loss.

How to Make Low Carb Chicken Fajita Soup in An Instant Pot

Then add the onion and peppers. Cook until soft – about 4 or 5 minutes.
