Say goodbye to an hour spent hovering over the stove perfecting sweet, buttery onions. This recipe uses an Instant Pot to speed up the process and paves the way for French onion soup, omelets, sandwiches and sausage toppings all week.
Add onions, butter, 2 teaspoons salt, and 1/2 teaspoon pepper to the bowl of a multicooker; stir to combine. Secure the lid and adjust vent to seal. Cook on high "Pressure Cook" setting for 5 minutes. Once cycle is complete, immediately release pressure. Carefully remove lid.
Strain onions and discard excess liquid. Return onions to multicooker. Cook over high "Saute" setting, stirring constantly, until onions are deeply golden and caramelized, 3 to 5 minutes. Store in an airtight container in the refrigerator for up to 1 week.
