Jarred spaghetti sauces make it possible to whip up pasta dinners in a jiffy, but they often leave you feeling like something is missing. It could be the lack of robust seasoning, the absence of subtle heat, or a need to balance the tartness of tomatoes. Regardless, these sauces often just need a little something to add an oomph—something that will take a run-of-the-mill jarred spaghetti sauce to delicious new heights.

What is MSG?

The key ingredient you’re looking for could be MSG—monosodium glutamate. MSG is a savory ingredient that has been unfairly maligned over the years, mainly due to myths rooted in racism. Despite its bad rep, MSG is generally safe to consume, unless you’re particularly sensitive to it. Luckily, a pinch of MSG is all you need for a big impact. MSG is composed of glutamic acid and sodium. Glutamic acid is the amino acid responsible for bringing out that sought-after fifth taste—umami.

How to Add MSG to Pasta Sauce

MSG can make just about anything taste better, and it truly shines when paired with equally complex, savory, and umami-rich ingredients like tomato-based spaghetti sauces. To use MSG, start small and add more as you taste. Generally, about half a teaspoon for a family-sized dish (about four servings) is enough. Despite its sodium content, MSG actually contains less sodium than traditional salt. But remember, MSG is an enhancer, not a fixer. It will amplify existing flavors rather than add new ones.

Other Ways to Upgrade Jarred Pasta Sauces

MSG isn’t the only way to boost the flavor of jarred spaghetti sauce. Look for other umami-rich ingredients like mushrooms or salty anchovies. Adding extra aromatics such as onion, garlic, and herbs can also elevate the dish. For a bit of heat, try chili flakes, smoky paprika, cayenne powder, or even gochujang. Cheese is another surefire addition; melt creamy cheeses like ricotta into the sauce or add Parmesan rinds while it cooks. A final garnish of cheese can make a world of difference.
