3 Tbsp butter

2 Tbsp olive oil

2 lbs potatoes (4-5 medium sized), cut into 1/2" cubes

3 leeks, white and light green parts only, thinly sliced

2 large celery stalks, diced

1/2 cup onion, diced

3 garlic cloves, minced

6 cups broth or stock (I prefer vegetable)

4 sprigs of fresh thyme

1 1/2 tsp sea salt

3/4 tsp ground black pepper

1 cup half & half


  1. Prep your vegetables if you have not done so already.
  2. Set your Instant Pot on Sauté.
  3. Add butter and olive oil once your pot is hot.
  4. Add onion, celery and leeks to the pot.  Cook about 8 mins or until tender. Stirring frequently.
  5. Add garlic to vegetables, cook about 30 secs until fragrant.
  6. Stir in salt, pepper, broth, thyme sprigs and stir to deglaze the pot.
  7. Close lid on Instant Pot and set to 10 mins on high pressure (Keep in mind it could take about 8 mins for your Instant Pot to get up to pressure, hence the added cook time on this recipe.)
  8. Once the timer goes off, quick release and then turn pressure cooker to a low sauté.
  9. Remove twigs of thyme from pot (The leaves will be in the soup) They're easy to grab with tongs. 
  10. Use an immersion blender to smooth the soup just a bit, leaving some chunks, unless you prefer it completely smooth.  I just do 10 pulses.  ***Another option is: Transfer about 4 cups of soup to a blender and puree until smooth and return to the pot.  This way you'll have a semi-chunky soup as well if you do not have an immersion blender.
  11. Once the soup is back up to a simmer, stir in the half and half and sauté until slightly thickened, about 5 minutes.
  12. You may enjoy the soup immediately or let cool to refrigerate for the next day.



This potato leek soup can be enjoyed the same day, but it's even better the next day.  Reheat in a small pot at low temp in the microwave.  Try it topped with some crispy fried onions or jalapenos to give it an extra kick!
