Saute: Turn on Instant Pot on Saute (high). When display reads 'hot', add oil, onion, garlic, pepper and saute for 30 seconds. Add ground meat, break it up with a spoon and saute for 2 minutes.
Pressure Cook: Add all spices, soy sauce, marinara sauce and broth. Add elbow macaroni and stir. Close lid and pressure cook on Manual/Pressure Cook for 3 minutes. (Check notes for pasta cooking times in Instant Pot)
Release Pressure: Once the cooking is done, you can release pressure immediately, or after 5 minutes. If you are multiplying this recipe, I recommend waiting for 5 mins, as that prevents a mess-free release. You can release pressure by turning the valve to 'Venting ' position in DUO models, or , press down the pressure valve in ULTRA models.
Garnish and Enjoy: Open the lid after the pin drops. Serve warm and garnish with your favorite shredded cheese and enjoy!
