Add the onion, garlic, smoked paprika, red pepper flakes, water, maple syrup, and apple cider vinegar to the Instant Pot. Next, add the collard greens. You will have to push down on them so they don’t stick out of the pressure cooker.
Place the lid on the pressure cooker, lock it and set the valve to “Sealing.” Cook for 5 minutes on high pressure.
Once the time is up do a manual quick release of the pressure by moving the valve to “Venting.”
Open the lid and transfer vegan collard greens to a serving bowl or serve from the Instant Pot.
