Immune Boosting Soup

Immune Boosting Soup

As we are in the dead of winter there’s always sicknesses that go around. Personally, I HATE being sick and will do anything I can to prevent it. This soup is full of flavor but it’s also really good for you and fortifies your immunity. It’s packed with ingredients like garlic, ginger, turmeric, and leafy greens which contain anti-inflammatory, antioxidant, and immune-supportive benefits. It’s also got a bit of protein and fiber from the lentils. You can make this soup in the Instant Pot or in the slow cooker. It’s ideal for cozy days or when you’re feeling under the weather. Enjoy!

Ingredients/Substitution Ideas

  • Olive oil
  • Yellow onion–or white
  • Water
  • Better than Bouillon vegetable base–or you can use vegetable broth
  • Brown lentils
  • Carrots–or sweet potato, butternut squash
  • Cauliflower florets–or potatoes
  • Celery
  • Garlic
  • Ginger root–I like to freeze it and then grate it, it is so much easier
  • Ground turmeric
  • Black pepper
  • Dried parsley
  • Spinach–or kale
  • Lemon

Steps

Turn Instant Pot to saute setting. When display says HOT add in the oil and swirl around. Add in the onion. Saute for 4 minutes. 

Pour in the water and scrape bottom of pot so that nothing is sticking. Stir in the bouillon and the lentils and let the water start heating up while you prepare all the other ingredients. 

Add in the carrots, cauliflower, celery, garlic, ginger, turmeric, pepper and parsley.

Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the SOUP button to 8 minutes. When time is up let pot sit for 5 minutes and then move valve to venting. Remove the lid. 

Stir in the spinach and lemon juice.

Serve and enjoy!

Notes/Tips

  • Serve with crusty bread. Homemade french bread is always a good choice!
  • This recipe is gluten free, dairy free and vegetarian.
  • You can add in rotisserie chicken if you’d like to bump up the protein.
  • I used my 6 quart Instant Pot*. You can also make this in a 3 or 8 quart pot.
  • Store leftovers in an airtight container* in the refrigerator for up to 4 days or in the freezer for up to 3 months.
  • Other recipes you can make with turmeric are Hidden Soup and Sunshine Casserole.
Did you know you can filter the recipes on my website to search by meat type, IP or Crockpot, low carb, gluten free, etc.? Use the filter to find exactly what you are looking for.

    Perfect timing! Just finished a pot of your Tuscan White Bean Soup & was thinking of another to make today. This will be perfect, as usual you have saved the day! Pollen count down here in FL has been rough the past few weeks, got us all ‘croaky’. It’s everywhere, what’s not on the top of my car is up my nose!! 🙁
