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!

Notes
Using different shaped pasta: To adjust the cooking time for a different shaped pasta, I half the lower number in the suggested cook time on the box, and subtract 1 minute from that. So, if a box suggests the cook time as 10-11 minutes, I cook it for 4 minutes in the Instant Pot (10/2=5; 5-1=4).
How to release pressure manually: Reduce the pressure cooking time to 2 minutes, and let the pressure release naturally for 10 minutes (NPR 10 minutes). In that time, most of the pressure would be released naturally, and if you do a quick release at this point, it won’t be that impactful and long.
Adjust the quantity of water: This recipe has been tested in a 6-quart Instant Pot. If making this in an 8-quart size, adjust the water quantity to meet the minimum requirement.
Multiplying the recipe: This recipe can be easily doubled in a 6-quart or 8-quart pressure cooker.
Don't skip the soy sauce: This may seem like an untraditional ingredient, but it adds an element of umami to this dish. Do try it and you'll see for yourself.
