For the Instant Pot:

  • 1 cup Wild rice uncooked
  • 3 Carrots a bit more than 1 cup, diced
  • 3 stalks Celery
  • 1 cup Onion
  • 4 cloves Garlic minced
  • 8 oz Cremini Mushrooms sliced
  • 4 cups Broth vegetable or chicken
  • 1/2 tsp Thyme dried
  • 2 Bay leaf
  • 1/2 tsp Rosemary I used dried
  • 2 large handfuls Kale leaves roughly chopped with thick stems removed
  • 1.5 tsp Salt
  • 1/2 tsp Black Pepper freshly cracked

For the stovetop:


Instant Pot:

  • Add all ingredients to the Instant Pot and stir to combine. Close lid with vent in sealing position.
  • Cook for 30 minutes in soup mode, then allow a natural pressure release.
  • Open the lid, then remove and discard the bay leaves.

On the stovetop:

  • When the pressure cooking is done, melt the butter in a pan on the stovetop.
  • Add the flour and saute for a minute until the raw smell is gone (about 1-2 minutes).
  • Whisk in the milk, a little at a time until you have a smooth, thick consistency.

Mix it together:

  • Add the roux to the Instant Pot and stir well.
  • Serve and enjoy.


Crockpot: This soup can be made in a Crockpot. Cook for 2-3 hours on high and then follow the steps for the roux before adding to the Crockpot. 
Broth: I have used Better Than Bullion base to make broth. It is just easier to keep at hand for all my cooking.
Pressure Cooker: This recipe was created in a 6qt Instant Pot DUO60 Multi-use Pressure Cooker.
