this was just all right for me. It definately needed more sauce, when it was all cooked and done it seemed like nothing more than tomatoes and onions. If I make it again I will add a can of tomato sauce. Read More

When I made this recipe I did make some changes. Instead of 1 tablespoon of tomato paste I put in 2 tablespoons. I also put in 1 and half cups of water instead of a quarter cup. Also sometimes tomatoes from a can can taste kind of yucky so I added 5 fresh tomatoes. I do agree that there was not enough sauce so next time I think I'll add more sauce. The last change I made is I put in cilantro (I think about 3 tablespoons). Read More

The sauce is wounderful and my son loved it. But one draw back the suace was not enough for one pound of spagetti. I would change to recipe to have double the liquid portion of the recipe. Read More

Pretty straightforward recipe. I read the other reviews about there not being enough sauce and they were right. I minced the onions and added a couple of fresh tomatoes at the end because there wasn't any sauce left once I added the spaghetti so definitely add more tomatoes. Next time I'll double the sauce but not the paste all for the same amount of spaghetti. Thank you Natalie for the recipe. Read More

I love onions so I thought this would be a great recipe to try. It was good but it seemed like the dish was lacking something. Maybe if I had had some shredded parm that would have helped. Of course the fact that I didn't use fresh basil may have really taken away from the overall flavor. I'm sure I'll try it again with a few minor adjustments. Read More

This is basically how I make spaghetti. I usually use about 2 onions a large can of petite diced tomatoes and a regular can of tomato sauce. We used to go to granny's every Sunday and she would have this on the table every now and then. It was just plain spaghetti and some kind of tomato something with it. I'd seen her plop a whole stick of butter in it! I've done it a few times when I felt the urge. I've tried many different variations and this is the closest I could get to what she made. This is the only spaghetti I eat. Read More
