Lentil Barley Soup Kit Make-Ahead Pressure Cooker Recipe

A guest post from Kayla…

On our recent garage saling adventure Mom mentioned how much she likes having all of her different kids so she can try all different new things. I am her weird food kid. She’s always game for a trip to Oneota Food Coop and will try all of the food I like. I always call her when I find something new like our favorite electric pressure cooker or roasted radishes.

When I found out Mom would have to follow a low-iodine diet I knew the best way to help was with food. I knew she would be tired and not feel like cooking but would also not be able to eat convenience food. She is not to have much meat, eggs, or dairy, which is my specialty. I put together a few lentil barley soup kits for the freezer.  Her electric pressure cooker is so convenient that all she needed to do was put the freezer kit I provided in, add water and push a few buttons. It makes a big batch so she could warm up leftovers in the microwave.


Mom turned out really liking the soup and asked for the recipe! It is adapted from my favorite cookbook, Vegan Pressure Cooking, to suit her low-iodine diet. Even if you are not vegan I highly recommend this book for anyone who would like to eat more whole foods but doesn’t want to “eat like a bird.” The meals come together in just minutes and use simple ingredients that you can find in small-town grocery stores. I have bought it three times over because I keep giving my copy away.

Ingredients for Soup Kit

  • 1 C pearled barley
  • 1 C lentils
  • 3 carrots, chopped
  • 3 stalks celery, chopped
  • 1 onion, diced
  • 2 cloves garlic, minced
  • 1 t salt (iodine-free for low-iodine diets)
  • 1/2 t black pepper
  • 1 t dried thyme

Ingredients for Cooking Day

  • 7 C water
  • 16 oz mushrooms, chopped


  1. Place all ingredients in freezer safe zipper seal bag.

On cooking day, dump ingredients into pressure cooker. Add water and mushrooms. (It looks like Mom added kale too!) Cook at full pressure for 30 minutes with quick release.  Eat.  YUM!!

  1. Hi Jo
    I have thyroid cancer and was told to stay away from Kale by my specialist. You might want to look into this.


  2. HI Kayla, are the lentils raw or can they be cooked before adding? Also is if quick cook barley or the old fashion kind. Thanks.

  3. I made this in the crockpot. I just put all ingredients in crockpot for 4 hours on high (could also do 8 hours on low).

  4. This is really tasty! Thanks. I sauteed the onions and garlic first, then added the rest and pressure cooked as noted 30 min, then released pressure after 5 minutes. More like thick pottage than soupy. Very good!
