Bring water into a boil in a big saucepan/pot over medium-high heat. Add pasta, season with salt and cook al-dente. Drain and set aside about 1/4 pasta water.
While pasta is cooking, in a pan, add ground beef and cook over medium-high heat, when the beef is almost done (making sure of stir to break the beef up), drain any fat if needed and seasoning with Italian seasoning, onion powder, garlic, diced onion and stir and continue to cook.
Add pasta sauce, red pepper flakes, seasoning powder (if you’re using), salt and pepper and combine. If the sauce is thick and you need add liquid use the pasta water you reserved, discard if you don't need but make sure your sauce is not thick.
All to rest, cut with a spatula, and serve.
