Turn on your Instant Pot and hit the saute button. Choose normal heat and set it for 7 minutes. Wait until the display says 'hot,' then pour in the olive oil.

Toss in your chopped onions and carrots. Let them cook for about 6 minutes until they're soft and starting to brown a bit. Add the minced garlic and stir for another minute until it smells amazing.
03 -
Pour in a tablespoon or two of vegetable broth and scrape up any browned bits stuck to the bottom of the pot. This helps prevent burning and adds flavor.

Throw in the rinsed lentils, ketchup, mustard, brown sugar, chili powder, Worcestershire sauce, hot sauce (if using), salt, and the rest of your water or broth. Don't add the barbecue sauce yet—save that for later.

Secure the lid on top and make sure the vent is set to 'sealing.' Press the high pressure button and set the timer for 15 minutes. The pot will take around 10 minutes to build up pressure before cooking starts.
06 -
When the timer goes off, let the pressure come down naturally—this takes about 15 minutes. Carefully remove the lid, stir in the barbecue sauce, and you're done!

Pile the lentil mixture onto toasted burger buns and top with whatever you like—lettuce, onion, pickles, or avocado all work great.
