Instant Pot Lemon Orzo Soup

  • Author: Laura
  • Total Time: 13 minutes plus time to come to pressure
  • Yield: 6 servings 1x


  • 2 Tbsp butter
  • 1 Tbsp olive oil
  • 1 cup diced onion
  • 1 cup diced carrots
  • 1 cup diced celery
  • salt (according to your personal preference)
  • ½ tsp oregano
  • ¼ tsp pepper
  • ¼ tsp red pepper flakes
  • ¼ tsp paprika
  • 1 twig fresh rosemary or ½ tsp dried rosemary
  • 1 Tbsp minced garlic
  • 6 cups water
  • 1 Tbsp Chicken Better Than Bouillon
  • 1 cup orzo pasta (I think you can use 3/4 cup)
  • 1 1/2 lbs boneless skinless chicken breasts, cut into pieces (I cut in half lengthwise and then cut each half into 2 pieces)
  • 2 Tbsp to ¼ cup lemon juice (based on taste)
  • 1 1/2 Tbsp cornstarch, optional to thicken (if using mix with 1 1/2 Tbsp water to form a thick smooth slurry)


  1. Turn Instant Pot on to sauté mode. Add butter and olive oil. When the butter begins to melt add in the onion, diced carrots, and celery. Sauté for 1 min. Add the salt, oregano, pepper, red pepper flakes, and paprika. Sauté for 2 mins. If adding dried rosemary add it now.  Mix in garlic and sauté for just 20 seconds.
  2. Turn off sauté mode. Add water and deglaze the pot very well by scrapping the sides & the bottom of the pot with the help of your spatula. There should not be any food particles stuck at the bottom of the pot. This is important and will prevent getting a burn error. Mix in the better than bouillon.
  3. Add the orzo pasta and mix in well. Place the chicken breasts pieces on top of the pasta and DO NOT stir of mix. Throw in the fresh rosemary twig if using the fresh.
  4. Put on the lid and make sure valve is set to seal. Pressure cook on high for just 3 mins. Once the cooking cycle perform a quick pressure release by moving the valve from the sealing to the venting position. Remove the lid when pressure is completely released.
  5. Remove the fresh rosemary twig & discard. Remove the chicken pieces and shred them with a fork. Add lemon juice into along with the shredded chicken and stir to combine.
  6. If you wish to thicken the soup, add the optional cornstarch slurry. Stir well bring to a simmer on the sauté mode for about 1 min or until the soup thickens a bit.
