Season the chicken thighs with salt and black pepper. Press the "Sauté" key and when the instant pot displays "hot", heat the oil and sear the chicken for 5 minutes on each side. Set aside.
Add the onion, cook until tender for 3-4 minutes. Add garlic, cook just until fragrant. Add in the broth. Be sure to scrape up any brown bits from the bottom of pan to flavor the soup and to prevent burning.
Add the rinsed rice, salt (optional), and the seared chicken thighs back into the pot. Secure the lid and set it to "manual" on high for 5 minutes. Once the cooking cycle is completed, let the pressure release naturally for at least 15 minutes then move the valve to venting to release the remaining pressure.Transfer the chicken thighs to a plate and shred into small pieces.
Fill a blender with a cup of rice and broth mixture, egg yolks, and lemon juice. Puree until smooth.Return the pureed soup and shredded chicken into the pot, simmer until thickened slightly for a few minutes. Do not let it come to a boil, stirring often. Add more salt, pepper, and/ or lemon if necessary and according to your liking. Serve and enjoy!
Notes
Rinse the Rice. Don't forget to rinse and drain the rice before cooking. Lemon. If more lemon juice is needed, add in small increments of 1 teaspoon at a time.Consistency. Please note the consistency of the soup is actually much thinner than pictured above. Funny thing is that this is actually due to the amount of time I spent taking those pictures... the soup was out for a while and got thicker :) If you want a thinner soup you can add more broth later. Do not fill your Instant Pot more than ⅔ full. Pressure release. To prevent big messes and bad burns, always handle hot liquid (soup) carefully. Do not use the quick release as the thick liquid will splatter out.Once the high-pressure cooking cycle is completed, you have to wait at least 15 minutes or let the pressure release manually before opening the lid.
