Homemade Onion Soup Mix

This homemade onion soup mix is the perfect replacement for store-bought packaged mix. Store your mix in an airtight container for several months.

A few weeks ago, I shared my recipe for slow cooker pot roast.  Outside of the beef, the main ingredient is dry onion soup mix.

I used to buy the onion soup mix you can get at the grocery store – you know which one I’m talking about.  The square packet in the soup aisle.  And then I looked at the ingredient list and kind of freaked out a little bit.

I need to stop looking at ingredient lists or I’m never going to be able to go into a grocery store again.

Chemical after chemical, or at least a bunch of scientific names I couldn’t possibly know the meaning of.  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 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 didn’t want to use any 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. Also, vegetarians and vegans can use this mix too when it is excluded.  This is also gluten-free (unlike the store-bought stuff.)

I came up with this recipe instead.  Its perfectly onion-y pungent and is really good with my pot roast.

Store your soup mix in a sealable container for up to 2 months.  Make sure you give it a good shake before you measure because the smaller spice parts sink to the bottom.  If you are using this recipe to replace a store-bought package, you will need 5 tablespoons of it.

Once you have mixed up your soup mix, you can use it to make soup, slow cooker pot roast or onion dip.

Why is this only good to store for 2 months? Most dry spices last a year
