There are a ton of uses for onion soup mix. It has a special flavor that turns an ordinary recipe into a crave-able, addictive, dish with no effort at all. Just blend a serving into some meatloaf and everyone will ask for seconds. It can turn shredded beef or a chip dip into a flavor-packed party.

Stir it into rice, add it to pot roast or whip it into mashed potatoes for instant flavor. The possibilities are endless and it is a fast way to transform a meal or appetizer. If you love all the flavors of onion soup then you will love this spice blend.

Low in sodium and no MSG.

The problem many people have with store-bought onion soup mix is the high sodium content and the MSG. However, reducing the sodium and eliminating the MSG makes the seasoning mix pretty bland. MSG gives things that special, crave-able umami flavor. It is a distinct flavor that no amount of salt could ever mimic.

So how did we get that umami flavor without using MSG? We used three different ingredients to make this onion soup mix a home-run.

These are not your ordinary pantry ingredients so you will have to plan ahead if you want to make this seasoning mix. You can purchase them online but it is worth the wait.

The umami powder is made with dried shitake mushrooms and gives the most kick to the seasoning mix. When you order the umami powder, you will get more than you need for this recipe but that is a good thing. You will want to use it for a lot of things.

Sprinkle it on steak, chicken, salad dressings, roasted veggies…. It does have some salt in it but if you use it in place of salt then you will reduce your sodium intake and enhance the flavor of anything you eat.

The tomato powder and Worcestershire powder are pretty self-explanatory. Just dried, powdered forms of those two ingredients. They add some extra layers of umami flavor without making the sodium content go through the roof.

We had tried using powdered soy sauce for a bit of umami but the soy sauce brought the sodium level up pretty high. A tablespoon of soy sauce has 880 mg of sodium while a tablespoon of Worcestershire sauce only has 167 mg of sodium.
