If you want creamy pasta but would rather use no cream, there are a few alternatives. Half & half is creamy but with a third of the fat. Whole milk thickened with cornstarch or flour works well. Plain Greek yogurt or cream cheese are good choices, too. Coconut milk is a non-dairy alternative but it does have a flavor so isn't suitable for all pasta dishes. If you're just not a fan of creamy pasta, try a basil pesto sauce or tomato-based spaghetti sauce.
