Homemade Onion Soup Mix 

Homemade onion soup mix is easily one of my favorite things to make because it is so simple. Why buy it in the store when you can make it at home?

Use this to substitute for a one ounce package you would normally buy in the grocery store. 

This homemade onion soup mix is great because you can double or triple it to have more for later. I stored mine in a pint size mason jar because it has an airtight lid. It is also easy to use an old spice container and just relabel it. 

Recipe Inspiration 

Being a prepper and dealing with massive supply shortages since the Covid shutdown, I’ve made it a point to learn how to make things myself. Because there is nothing more frustrating than having a meal planned out and going to the store to find they’re out of a key ingredient. 

When I know how to make something myself, supply shortages aren’t nearly as obnoxious! I know I can handle it.

Make Onion Soup 

Place this homemade onion soup mix in a medium saucepan and stir in 4 cups of water. Bring to a boil and stir well. Reduce the heat to medium and simmer uncovered for about 10 minutes, stirring occasionally. This will make about 31/2 cups. 

Make Onion Dip 

Combine this homemade onion soup mix with 1 container (16 ounces) of sour cream. I like to let mine sit in the refrigerator overnight to rehydrate the dried spices and marry into the sour cream. Stir well before serving. 

Just like with my ranch dressing, this onion dip is even better if it has time to sit and chill in the refrigerator. Both make for excellent dips on game day or for any party. 

Onion Soup Potatoes 

Stir this soup mix into some olive oil. Peel and dice some red potatoes, and spray a cookie sheet or baking dish with a non-stick cooking spray. Stir in the potatoes to the oil and soup mix, until well-coated. 

Place into the baking dish or cookie sheet and bake at 400 degrees for approximately 45 minutes, or until the potatoes are fork tender but not mushy. The baking time will largely depend on how small or large the potatoes are diced. 

These potatoes are a favorite in my house because they’re so simple to do. My husband, Nathan, requests these often.

Homemade Onion Soup Mix Directions 

Measure all of the ingredients into an airtight container and mix together. You can either stir it with a fork, or just put the lid on the container and shake it up a bit. 

That’s it! It really is just that easy! 

Homemade Onion Soup Notes 

If you can’t find beef bouillon powder or granules, you can pick up the cubes and crush them up as well. I had to do this, and I found that 8 of the cubes equaled the 2 tablespoons that I needed. 

I used a small Ziplock bag and a meat tenderizer to put pressure on the cubes and break them apart. If the store doesn’t have what you need, improvise like this! 

If you are making a larger batch of this to store for later use, be sure to shake it up really well first, and then measure out ¼ cup of this homemade onion soup mix.

Why I Love This Recipe 

This recipe seriously cuts the salt out! Looking at the box of a prepackaged onion soup mix, salt is the number 2 ingredient, and is responsible for 27% of our daily sodium intake. Plus there is corn syrup and soy sauce in it. Holy salt, Batman! That mix also may or may not contain milk products. 

I am a big fan of knowing what is in my food, versus leaving that up to someone else by buying a prepackaged ingredient. This is a classic example of why making it myself is just healthier and easier. 

Great Gift! 

This homemade onion soup mix makes an excellent holiday gift. Simply prepare it, package it in a mason jar with an airtight lid, create a nice label and directions on how to prepare it, and give it as a gift. 

I have known people who have salt restrictions, and giving this as a gift for them to enjoy has been incredibly well-received. Because it is thoughtful to their dietary restrictions, but it is also giving them something that is useful and packs a great flavor without the additives. 

Giving a gift that is useful like this is the best kind of gift, in my opinion! 

Homemade Onion Soup Mix

Make It Vegan!

One of my closest friends is vegan, and I’m always looking for ways to use simple substitutions for when Nathan and I invite him to dinner, or when I share a recipe with him.

In this case, the only thing to substitute is the beef bullion powder for vegetable bullion. That’s it! Just one simple tweak and you’ve got a great vegan recipe.

    I’ve been buying onion soup mix and other similar mixes all my life for making dips, adding spice to potatoes, etc. That being said, I’ve never tried making my own before. I never even considered it… It’s FAR easier than I could have imagined. I am definitely going to give this a try so that we have it here on hand. I also love that by making your own, you can tweak it – for example, I’m not a big fan of beef bullion but I could swap it out for something that I prefer. Bonus!

  • Lyosha

    I love onion soup and it is very handy with the cold season approaching. Your mix is very useful to me as well, I’ll try your mix at home (and I know I’ll love it because your recipes never fail)

    • The Cooking Wife

      It’s even better because it is so easy to prepare, which I think is essential when you’re sick or just not feeling up to making a full meal. That is why I recommend making this mix ahead of time and keep it in the pantry, so it’s always ready.

    • The Cooking Wife

      I found that I really enjoyed the flavors more from my mix because the lack of salt let the other flavors shine through a lot more. I will never buy the pre-made stuff in the store again, that’s for sure!
