First wash and scrub potatoes and surface wash leeks
Peel potatoes (I hate peeling so I skipped this step). Cut potatoes into quarters lengthwise and cut them into about ½ inch pieces, and set them aside
Cut off dark green parts from leeks and discard them. All you have left is white and pale green parts
Cut large stalks in half and thinly slice everything. Throw them into large bowl and wash in cold water slices because leeks known to trap dirt in between layers. Drain all the water and set aside
Thinly slice shallot
Thinly slice Onion
Grate garlic
Press saute button on medium on your Instant Pot and wait till it says HOT
Add oil and butter
Dump all the spices into hot oil and let them blume while siring constantly so they don't burn. By doing this you let oil pull all the flavor out of the spices
Add shallots and onions and saute about 5 minutes or until soft. DON'T let them brown
Add drained leek slices and saute them stirring occasionally for about 10 minutes or until all wilted and reduced in size. Its ok if they brown a bit
That's how leeks will look like
Sprinkle flour, mix it through and cook for a minute to get raw flour taste out
Add about 2 cup of broth to the pot and deglaze the bottom of the pot. Scrape everything from the bottom, these are the tasty bits and add rest of the broth
Add potatoes
Put lid on and set venting valve to sealing
Press CANCEL button and press MANUAL or (PRESSURE COOK button depending on your model) and set timer for 7 minutes. Remember pressure cooker will take about 10-15 minutes to get up to the pressure, so it'll say ON on the screen. When it gets up to pressure it'll starts counting time down.
When 7 minutes are up then let your pot depressurize naturally for 15 minutes. The timer will count up, and after 15 minutes flip venting valve to vent. If it spits out liquid, close the valve to seal, wait few second and open it again. Be careful DON'T burn yourself. When pressure indicator drops down you can open the lid.
This is important!!! Use slotted spoon and fiend bay leafs and discard. DON'T bland them
Add salt and stir and taste.
Use immersion blender and and blend everything till smooth consistency
Add half and half or heavy cream and using immersion blender stir it throg. Now at this time all the blended stuff absorbed the salt so unjust agai for salt.
Let it sit for few minutes and serve topped with chives and sour cream or croutons
