Step number 1. Sauté the beef. Turn an electric pressure cooker on to sauté. Once heated, add the olive oil and beef. Break the beef up into large pieces with a wooden spoon and season with the salt, onion powder, and garlic powder. Cook, stirring and breaking the beef into smaller and smaller pieces, until cooked through and no longer pink, about 5 minutes.
Step 02, Add 1/2 cup of the water, then the sauce. Turn off the sauté function and add 1/2 cup of the water to the pot. Scrape the bottom of the pot to remove any stuck-on bits. Add the sauce and stir to combine well.
And then, Break the spaghetti in half and layer in the pot. Break the spaghetti strands in half and spread them in one or two layers over the ground beef mixture. Do not stir from this point on.
