Turn Ninja Foodi on and add the macaroni, chicken broth, salt, and pepper.
Close pressure cooking lid, and move valve to the seal position. Pressure cook on high for 2-3 minutes.*If you are using a different shape of pasta, follow these instructions to determine the proper pressure cooking time: Take the recommended cooking time that is on the box of pasta and divide by 2 and then subtract 2. Pressure cook for that many minutes. For example, if the box recommends 10 minutes of cook time, divide 10 by 2=5. Subtract 2. 5-2=3. Pressure cook for 3 minutes.
Once the timer beeps and the Ninja Foodi is finished pressure cooking, move the valve to the vent position and quick release the pressure. If a lot of liquid starts to come out of the Ninja Foodi, close the vent, wait 3-5 minutes and then try to release the pressure again. Continue to do this until all pressure has been released.
Add the butter and stir until melted and well combined.
Add ½ of the cheese and ½ of the milk. Stir until well combined.
Continue to add cheese and milk a little at a time, stirring frequently. You may want more or less milk based on your preference. Adjust accordingly.
It's time to eat! Enjoy!!
Notes
What if I want to cook a different type of pasta in the Ninja Foodi?No problem! Simply use this calculation for al dente pasta: Take the recommended cooking time that is on the box of pasta and divide by 2 and then subtract 2. Pressure cook for that many minutes. For example, if the box recommends 10 minutes of cook time, divide 10 by 2=5. Subtract 2. 5-2=3. Pressure cook for 3 minutes.If you prefer your pasta cooked a little more: Take the recommended cooking time that is on the box of pasta and divide by 2 and then subtract 1. Pressure cook for that many minutes. For example, if the box recommends 10 minutes of cook time, divide 10 by 2=5. Subtract 1. 5-1=4. Pressure cook for 4 minutes.If you prefer your pasta completely cooked and tender: Take the recommended cooking time that is on the box of pasta and divide by 2. Pressure cook for that many minutes. For example, if the box recommends 10 minutes of cook time, divide 10 by 2=5. Pressure cook for 5 minutes.
