Let’s steam hot dogs in the instant pot. Peel and thinly slice lengthways the onions and place into the instant pot with olive oil and sauté until the onions have softened. Then press cancel and add in the two vinegars. Deglaze the instant pot with one cup/240ml of warm tap water.

Add the hot dogs and the water from the jar of hot dogs and stir. Then add enough water so that the hot dogs are ¾ submerged.

Place the lid on the instant pot, set the valve to sealing and pressure cook for 0 minutes followed by a quick pressure release.

After releasing the pressure, add the air fryer basket or a steamer basket and add the hot dog buns, add the lid and put the instant pot to sealing position and leave the instant pot for a couple of minutes for the hot dog buns to warm up.

Then serve the hot dogs in buns with the onions and your choice of sauce.
