Warm up the Ninja Foodi using the saute function set to high.
Add in the ground beef and cook until well done.
Drain if needed and return the beef back to the pot of the Ninja Foodi.
Add in the pasta, Italian seasoning, garlic, spaghetti sauce, and water.
Stir this up and be sure the liquid fully covers the pasta.
Secure the pressure cooker lid onto the Ninja Foodi and set the nozzle to 'seal'.
Cook on manual high pressure for 6 minutes.
Quick-release when it's done cooking, this means immediately turn the nozzle to vent and release the steam.
Remove the lid, stir it up and let cool for about 5 minutes and serve.
Notes - Most gluten-free pasta comes in 12oz boxes, so you can use 12-16oz of pasta for this recipe. The 12oz size works just as well as 16oz. We typically always use spiral pasta for this recipe. The spaghetti sauce can be Ragu, Prego and any variety will work.I use this Perfect Pinch Italian Seasoning.
