Key move
Butter instead of olive oil. Milk solids neutralize tomato acidity, creating a velvety orange-red sauce. Gentle simmer only—aggressive boiling breaks the emulsion.

Tastes metallic or too acidic?
Your tomatoes were low quality. Add a pinch of sugar or a tiny pinch of baking soda to neutralize the can taste. Stir well and simmer for another 5 minutes.
Butter separated into oily pools?
You boiled it too hard and broke the emulsion. Next time, keep it at a gentle simmer—tiny bubbles, not a rolling boil. You can try whisking vigorously off the heat to re-emulsify,…
Chef's Notes
The onion is discarded—it's there only to sweeten the sauce. Don't mince it; just halve it with root end intact.
Gentle simmer is critical. Aggressive boiling breaks the butter emulsion and makes the sauce greasy.
Perfect over any pasta. Toss with reserved pasta water for a silky coating.
