We’ve all been there: the moment when the rich, comforting taste of tomato sauce on pasta turns into a painful burn in your chest. It’s the kind of heartburn that makes you regret the lasagna you thought was “worth it.” While many blame garlic or wine for the discomfort, chefs who regularly cook with tomatoes have found a surprising trick to neutralize the burn. Instead of reaching for antacids, they’re turning to something much simpler from the baking aisle.

Why Tomatoes Are a Heartburn Trigger
Tomatoes are full of flavor, but their high acidity is what makes them a double-edged sword. While the tangy taste adds a delightful bite to marinara, it’s also responsible for the discomfort some people feel hours after eating. The acidity in tomato sauce typically hovers around a pH of 4, which means it’s quite acidic, and when consumed in large amounts, it can irritate your esophagus. This is why some individuals can enjoy their pasta without issue, while others find themselves reaching for heartburn relief after dinner.
How Baking Soda Calms Tomato Sauce
The trick that many chefs swear by to reduce the acid’s sting involves adding a small pinch of baking soda to the sauce. Baking soda, or sodium bicarbonate, is a mild base that neutralizes the acids in the sauce, making it less harsh on your stomach. When you add baking soda, it reacts with the acids and releases carbon dioxide, which results in a gentle foam on the surface of the sauce. The pH of the sauce rises, making it much milder without sacrificing flavor. It’s a simple trick, but one that can make a huge difference in how your body feels later on.
Simple Steps to Use Baking Soda in Tomato Sauce
The method is easy and doesn’t require fancy ingredients. After cooking your tomato sauce as usual, simply sprinkle in a tiny pinch of baking soda—about 1/8 teaspoon for a family-sized pot. Stir it in and watch the reaction unfold. Let it simmer for a few more minutes, then taste it. The sharpness should have softened, leaving a rounder, more mellow flavor. If it’s still too acidic, add another small pinch, but be careful not to overdo it. A little goes a long way, and it’s important to adjust to your taste. This small tweak can transform your sauce into something that’s both delicious and easier on your digestive system.
