1-2cupscheeseI use a mix of mozzarella and parmesan
Brown beef: Set instant pot to saute and add oil. Brown beef, then stir in the onion, garlic powder, thyme, salt, pepper, tomato paste and balsamic vinegar. Cook for 30 seconds, stirring constantly.
Deglaze: Pour the beef broth into the pot, scraping any bits off the bottom of the inner pot (not doing this correctly will trigger the burn warning!). Stir in the tomatoes and dry pasta.
Cook: Pressure cook for 3 minutes (for pasta that indicates more than 9 minutes of regular cooking time on the package, cook for 4 minutes), then quick release the pressure and open the pot. Stir in the cheese, cover with the lid and let sit for 3-5 minutes or until cheese has melted. Serve immediately.
This serves 6 for us, but if you have big eaters (teen boys!!) it might only serve 4.
