My daughter-in-law and I both prepare our spaghetti dishes with pre-packaged spaghetti sauce, bottled or canned. We both add it to browned ground beef. I use it as a base - to which I add sauteed onions, diced tomatoes, freshly pressed garlic, extra seasonings (basil, oregano, thyme, sage, coarsely ground black pepper, paprika and a bay leaf). I brown the meat (sometimes using ground turkey instead of beef), drain & remove, saute the onions & garlic with a little olive oil (evoo), add all the seasonings (except bay leaf) and simmer a little (about 5 minutes). Return ground meat to the pan, add tomatoes, canned/bottled spaghetti sauce, bay leaf - and simmer about 20 to 30 minutes. I then remove the bay leaf and serve over hot spaghetti noodles.
My daughter-in-law, boils the spaghetti noodles, while she browns the ground beef, then combines the cooked spaghetti noodles, the cooked meat and the pre-packaged spaghetti sauce in a large bowl, mixes with a spoon and serves it.
Is there any danger in not cooking the sauce?
