this recipe is decent for a shopping list. the first time i followed the recipe exactly, but the onions and garlic never broke down and melded with the other flavors. the second time I sauteed the onions and garlic in the olive oil, adding the herbs and spices one minute before removing from heat. i also added some chicken broth to thin it down and some sugar to calm the acidity of the store-brand tomato paste i bought. the result was delicious! three star recipe, five star results.


A great recipe for the slow cooker. After reading some of the reviews, I too decided to cut down on the herbs. Instead of using tablespoons, I used teaspoon measurements. It was awesome and went well with the gnocchi that I used. I think you need a heavy pasta to go with this sauce which turns out quite thick. I may even scale down the amount of tomato paste the next time around.


Not good, the spinach, carrots, and mushrooms are a good idea however the recipe calls for too much tomato paste and not enough crushed tomatoes. There was too much cracked red pepper and not enough garlic. My mouth was on fire, next time I will try my own measurements with the ingredients.
