This is Italian home cooking at its most honest โ ripe plum tomatoes slowly coaxed down into a silky, deeply flavored sauce with nothing but vegetables, olive oil, and fresh basil. The soffritto of onion, carrot, and celery builds a quiet sweetness in the base, and passing the finished sauce through a food mill gives it that smooth, restaurant-quality texture you just can't get from a jar. Every single ingredient here is naturally free of tree nuts, so there's no label-scanning or substitution stress involved โ just straightforward, wholesome cooking. For anyone navigating a chestnut allergy or broader tree nut sensitivity, a sauce like this is a genuine relief because the richness comes entirely from slow reduction and good olive oil. A pinch of sugar balances the acidity of the tomatoes, and the finishing drizzle of extra-virgin olive oil rounds everything out beautifully. Spoon it over pasta, use it as a pizza base, or freeze a batch for busy weeknights โ this is the kind of sauce that makes everything taste better.
