This easy instant pot spaghetti with homemade spaghetti sauce is nothing short of life-saving. Combining everything in the pressure cooker makes this a convenient one-pot meal, and it is ready in less than 30 minutes. While you can make this recipe in a traditional pressure cooker, with an instant pot you won't need to use your stovetop. All you have to do is saut the ground beef with the onions and garlic, add all of the remaining ingredients, set the cook time for five minutes at high pressure, and press start. A complete homemade spaghetti dinner just couldn't be easier, and you don't have to use commercially prepared sauces that have additives and preservatives you might wish to avoid. The cooking time is short, but make sure you plan on an additional 20 minutes (approximately) for pressure building and release. The recipe makes about four servings, and it is easily doubled for a larger family or leftovers. For a feast, serve with garlic bread and ceasar or wedge salad.
