It’s embarrassingly easy. The golden rule is simple: one part tomato paste to one part water. That gives you a basic, unseasoned tomato sauce.
For example, if your recipe calls for one 15-ounce can of tomato sauce, you’d use half a can of tomato paste plus half a can of water. But wait—there’s a secret weapon here.
Don’t just use plain water! Use pasta water, chicken broth, or even vegetable stock. That little swap injects so much more flavor into your emergency sauce.
The “Fry It First” Hack
Here’s where we get fancy. Before you add any liquid, sauté your tomato paste in a little olive oil for about a minute. This is called “frying the paste,” and it sounds weird, but trust me.
It deepens the color, caramelizes the sugars, and removes that raw, tinny taste. Your kitchen will smell like a five-star Italian joint. You’ll feel like a pro chef, even if you’re in sweatpants.
After frying, just whisk in your water or broth, and boom—instant sauce that’s arguably better than the canned stuff.
