Substitute for Parmesan Cheese
Hard, aged Italian cheese used for grating over pasta, salads, and soups.
The Best Substitute
The Professor's top pick for replacing parmesan cheese is Pecorino Romano at a ratio of 1:1 direct substitute. This works well for pasta, salads, soups, risotto. There are 2 total substitutes listed below, each suited for different situations. Scroll down for complete details on every option, including what to use each one for and what to avoid.
Best Substitutes
Pecorino Romano
Flavor impact: Sharper and saltier than Parmesan. Made from sheep's milk instead of cow's milk. Reduce salt in the recipe slightly.
Nutritional Yeast
Flavor impact: Nutty, cheesy flavor without dairy. Does not melt. Works as a topping but not as a structural cheese ingredient.
Dairy-free
Pecorino Romano is the classic swap. In fact, many traditional Roman pasta dishes (cacio e pepe, carbonara) use Pecorino, not Parmesan. It is sharper but excellent.
Frequently Asked Questions
It works in a pinch, but pre-grated Parmesan contains cellulose (anti-caking agent) that affects melting and flavor. A block of Parmesan grated fresh is significantly better.
The Bottom Line
If you are out of parmesan cheese, the best all-around substitute is pecorino romano. Pay attention to the ratio, since substitutes rarely work at exactly 1:1. Consider what role parmesan cheese plays in your recipe; whether it provides flavor, texture, acidity, or structure; and choose the substitute that best fills that specific role. When in doubt, start with less and adjust to taste.
