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.

This recipe sounds good, but it says you need to use 5 tablespoons to equal one packet of onion soup mix. That can’t be correct because it says it makes 12 servings and you would run out before you got to 12.

I love diy stuff. This seems like a wonderful recipe but how come every single diy recipes gets prefaced by "I saw the scary ingredients at the store" it's maddening. Sure, there's some ingredients to avoid but most are preservatives that become nessesary bc of how modern agribusiness works. It's also easier to learn which chemicals you don't like if you take a moment to learn about them. Some are just components from natural ingredients. Just once I wanna read a recipe like this that just talks about how fun and convenient it is to make food and store it. How nice it is to be self reliant like this I don't need to be scared of nonsense to read ur recipe

@Aisha, you must be very young or nieve? Researching recipes and finding out what's in them is a good thing. Right now they are trying to take the lables off of our meat? This is a bad thing, China who ships to the US kill dogs and cats and its them, they want to pass that on to us. People need to be aware of what some foods can do and harm your body. Some people are allgeric to meats and get terrible migrains.
