Classic, italian-style spaghetti sauce recipes often call for hours of simmering on the stove. Thanks to the pressure cooker, you can get a wonderful depth of flavor in under an hour. This recipe can be made using a stovetop pressure cooker or an electric model like the instant pot. Use the saut function to brown the meat and cook the vegetables before pressure cooking. Don't be intimidated by the ingredient list, it comes together quickly and easily. You can use different meats for this sauce if that's what you have on hand. Serve this rich spaghetti sauce over freshly cooked plain, whole wheat, or gluten-free pasta of your choice and top with grated parmesan cheese. Serve with some toasted garlic bread and a green salad tossed with tomatoes and a light vinaigrette. This sauce can also be used in a lasagna recipe, served over cooked ravioli or tortellini, or served on top of cooked spaghetti squash for a low-carb option.
