In a large 10 inch or more frying pan melt butter.
Add onion, celery, poultry seasoning, salt, and pepper and saute until onion is translucent.
Add cubed bread and half the broth. Incorporate the ingredients. Note: Use less or more of the broth but the final stuffing before cooking should be just slightly moist. You can use the remaining broth in the bottom of the pot and just add enough water to make 1 cups called for in the recipe.
Transfer the prepared stuffing to a bowl that will fit inside the instant pot liner on top of the trivet. This is where you decide to either cover the dressing with foil or leave it uncovered while cooking. If this is the first time you are making this recipe you may want to go ahead and cover the dressing with foil. If the dressing is too dry after cooking you can spoon some of the broth in the bottom of the pot to get it to the desired consistency.
In the Instant Pot liner with the trivet in the bottom Add water or remaining broth to bring it up to 1 cup of water.
Place the bowl of prepared stuffing on the trivet and make sure there is plenty of space around the bowl to allow steam to rise.
Next place the turkey legs on top making sure that they are inside the Instant Pot liner. Season the drumsticks with some salt, pepper and poultry seasoning.
Place the Instant pot liner with the drumsticks and stuffing in the Instant Pot pressure cooker. Plug in the unit. (Off will show in the display)
Place the lid on the Instant Pot pressure cooker and rotate the lid to the closed postion.
Move the pressure valve to the Sealing postion.
Select Poultry on the Instant Pot control panel and adjust the time to 60 minutes cook time.
As long as you don't touch another setting the Instant Pot will begin the cooking process after 10 seconds.
You will know when the Instant Pot cooking has completed when it beeps and goes to a warm cycle. The display will show and L with the time it has been in a warming state.
Once the cooking cycle is complete you can release the steam by moving the Steam Release to the Venting postion or you can let the Instant Pot release the steam naturally. (Important: do not attempt to remove the lid until the float valve has dropped indicating that the pressure has dropped to a safe level)
Once the steam has escaped you can remove the lid and you will have turkey drumsticks and stuffing hot and ready for dinner.
Notes: Based on feedback, there have been some suggestions from others.
To prevent excess moisture getting into the dressing, cover the stuffing pot. It can be difficult is you are using drumsticks but turkey thighs works much easier or even a partial turkey breast.
