Instant Pot® Sweet and Sour Pork

Turn on a multi-functional pressure cooker (such as an Instant Pot®) and select Saute function.

Add oil and heat until hot.

Add pork cubes, working in batches if necessary, and cook until browned on all sides, about 5 minutes.

Return all the pork back to the pot and cancel Saute mode.

Whisk together 3/4 cup water, ketchup, rice vinegar, pineapple juice, brown sugar, soy sauce, ginger, and garlic in a small bowl.

Pour over pork and stir to combine.

Close and lock the lid.

Select high pressure according to manufacturer's instructions; set timer for 5 minutes.

Allow 10 to 15 minutes for pressure to build.

Release pressure using the natural-release method according to manufacturer's instructions, about 5 minutes.

Release remaining pressure using the quick-release method.

Unlock the lid and remove.

Transfer pork to a plate using a slotted spoon.

Cover with foil to keep warm.

Select Saute mode and stir in onion, pineapple, and red and green bell peppers.

Simmer until vegetables start to soften, 6 to 7 minutes.

Whisk together cornstarch and remaining 1/2 cup water in a small bowl until smooth.

Pour slurry into the pot.

Cook, stirring constantly, until sauce has thickened to your preferred consistency, about 2 minutes.

Return cooked pork back to the pot and heat until just warmed through.

Garnish with sesame seeds.
