Caramelize the onion. Sauté the onion in oil in the Instant Pot until caramelized. Stir in the garlic and cook another minute.
Layer the flavors. Add the beef and bell peppers and cook for a bit. Add the wine and cook for a bit. Add all remaining ingredients and cook on Manual, High Pressure for 1 minute, and then let it naturally release pressure for 10 minutes.
Thicken the sauce. Carefully release the remaining pressure and open the pot. For a thicker sauce, turn on the Sauté function and cook until the sauce is thickened, stirring frequently, about 5 minutes.
