Homemade Onion Soup Mix Recipe

This homemade onion soup mix perfectly replaces the store-bought packaged mix. Gluten-free and vegan with simple ingredients.

I used to buy the onion soup mix at the grocery store – you know which one I’m talking about. 

The little packets in the soup aisle. And then I looked at the ingredient list and freaked out a bit.

I need to stop looking at ingredient lists and nutrient information, or I won’t be able to go into a grocery store again.

I didn’t know the meaning of chemical after chemical or even some scientific names, like disodium inosinate, disodium guanylate, etc. 

Not really my cup of tea right now. Or, in this case, my cup of soup.

So, I got to researching and reading. And re-reading the back of that envelope of dry onion soup mix. 

Because there are a few basic ingredients in onion soup mix and they are onion flakes and onion powder. Makes sense. I always have both in my spice cabinet.

I always make homemade mixes, like when I made my own taco seasoning recipe. When you make your own mixes, you have control over things like the sodium content. This is incredibly helpful if you are on a medically restrictive diet. 

Also, I wanted to use something other than beef bouillon, which you will see in several other homemade onion soup mix recipes. 

There were a few reasons behind that. Mainly, I don’t think of beef when I think of onion soup. 

But, also, vegetarians and vegans can use this mix too when it is excluded. This is also gluten-free (unlike the store-bought onion soup mix.)

Great news – I created my own homemade onion soup mix instead. It’s perfectly onion-y and pungent and is really good with my pot roast recipe.

Soup Mix Ingredients – No Beef Bouillon Powder!

Dry Onion Flakes – Dry onion flakes are the foundation for this homemade onion soup mix. They provide a concentrated onion flavor and contribute to the soup mix’s distinct texture and aroma. 

These flakes will rehydrate when combined with hot liquid, imparting that classic onion soup taste.

Parsley Flakes – Parsley flakes add a subtle herbaceous note to the onion soup mix, enhancing its overall flavor profile. 

Onion Powder – Onion powder intensifies the onion flavor in the mix and helps create a consistent onion taste throughout your recipes. It also adds depth and aroma to the mix, enhancing its versatility in various dishes.

Kosher Salt – Kosher salt acts as a seasoning agent that balances the flavors within the mix. It brings out the natural tastes of the other ingredients while providing a hint of saltiness to enhance the overall savoriness of your dishes.

Paprika – Paprika contributes a mild and smoky undertone to the onion soup mix. It adds depth and a touch of color, making the combination visually appealing. The subtle smokiness complements the onion flavor.

Garlic Powder – Garlic powder enhances the mix with aromatic and savory notes. 

It elevates the flavor profile by infusing a hint of garlic, making the soup mix versatile for various recipes beyond just onion soup.

Sugar – Sugar brings a touch of sweetness to the mix, balancing the savory elements. It rounds out the flavors, adding a subtle complexity that elevates your dishes.

Black Pepper – Black pepper provides a hint of spiciness and warmth to the onion soup mix. It complements the other seasonings and ingredients, adding a bit of zing to your recipes.

How to Store Homemade Onion Soup Mix

Store this spice mix in an airtight container, like a glass jar or mason jar, for up to 2 months in a cool, dry place. 

Ensure you give it a good shake before measuring because the smaller spice parts sink to the bottom.
