What to expect

Savory mushroom- and onion-forward flavor that boosts umami in a variety of dishes. It is used in small amounts to avoid oversalting; it’s versatile for soups, noodles, burgers, and roasted vegetables. Expect a powdery seasoning with noticeable mushroom notes, not a heavy-handed flavor, but saltiness can vary by batch.

👍 Best for
  • Boosting savory flavor in soups, stews, burgers, noodles, vegetables, and sauces; general umami enhancement
👎 Not ideal for
  • Very low-sodium diets due to variable salt content; those particularly sensitive to salt may want to monitor usage

The full guide

What this product is and who it’s for

McCormick Umami Seasoning with Mushrooms and Onion is a mushroom- and onion-based seasoning blend sold in a 4.59 oz bottle. Retail data label it as gluten-free, and the blend includes ingredients like salt, onion, mushroom, shiitake, spices, yeast extract and natural flavor. Priced around $7.06, it has a broad appeal for home cooks seeking an all-purpose umami boost. Designed as a versatile seasoning, it works well in soups, burgers, noodles, vegetables, and sauces. Use it in small amounts to control salt, as some reviewers note the salt level can vary from batch to batch.

Taste, texture, and use cases

This seasoning is mushroom-forward, offering savory depth without relying on large amounts of salt for flavor. Reviewers praise its flavor and versatility, with many finding it not overly salty and effective across many dishes. It’s a powder-based mix that can be sprinkled into soups, stews, meat dishes, or veggie sautés—essentially any dish that benefits from a mushroom- and onion-driven umami boost. Because salt perception varies, start with a pinch and adjust to taste.

Gluten safety and certifications
