Have you ever looked at the ingredients in some of the common food seasonings? Half the time I can’t pronounce quite a few of them. I don’t like feeding my family unknown substances. I’m sure some of them are harmless, but I don’t have time to look it all up. Instead, I try to make them from home when I can. And the most recent seasoning mix I needed was onion soup mix.

Admittedly, the store-bought onion soup mix isn’t too bad when you look at the information. Most of the high-level ingredients, meaning those that have the most in it, are standard. It’s those last few in the ingredient list that I’m not as sure about. Maltodextrin. High Oleic Sunflower Oil. Disodium Guanylate. Disodium Inosinate. Not to mention we are trying to avoid corn syrup. And look at that sodium content!

Ingredients and nutrition details for packaged onion soup mix

The largest difference is in the amount of sodium. Since the envelope of dry onion soup mix has to last a long time between packaging, shipping, and sitting on shelves at the grocery store, it has more preservatives. Those preservatives are what usually drive up the sodium.

I’ve used the onion soup mix in sour cream for a quick cracker dip as suggested on the box. I also use it for French Onion Steaks.

This recipe makes enough to substitute for one packet of Lipton onion soup mix. I make it just before using it and don’t typically store extra. If you would like to have it on hand, make a few servings and store it in an airtight container. Stir it up again well before using it. One packet is equivalent to about 1/2 cup of mix.

Serving Suggestions & Tips

  • You can add many flavors and other seasonings to your homemade onion soup mix recipe such as more dry onion flakes, parsley flakes, celery seed, or garlic powder. 
  • Only use dry ingredients to make your own mix, but combine it with wet ingredients, such as soy sauce, if you are making French Onion Soup mix. 
  • If you can’t find yeast extract, nutritional yeast will work in its place. 
  • Use the onion soup mix for everything from seasoning steak or ground beef to French onion dip to flavoring a slow cooker pot roast. This would also be great seasoning for vegetables like green beans and broccoli. 

Onion Soup Mix Step by Step

Ingredients

  • 1/4 cup minced onion
  • 1 cube beef bouillon
  • 1/4 tsp onion powder
  • 1/4 tsp parsley
  • 1/8 tsp celery flakes
  • 1/8 tsp paprika
  • 1/8 tsp black pepper
  • 1/8 tsp yeast extract

Preparation

Crush the beef bouillon cube. Mine has been in the pantry for too long, so they were not as easy to crush. They ended up as clumps, but the flavor was still there. In a small mixing bowl, whisk together all of the ingredients.

Storage: Place the extra soup mix in an airtight container and store it at room temperature in your spice cabinet for up to one month. A small mason jar works well for this.

      1. – glad to be reminded of this as a fun cooking project for the days/weeks ahead. I LOVE onion soup (as does my whole family), and we use the mix in lots of other recipes too, so whipping up some DIY mix will be fun!

        1. I have a feeling we will be needing a lot of DIY things like this in the coming weeks/months! And hey, cooking is a great math and home-ec lesson for the kiddos!

  1. 5 stars
    I need to make this asap! I love onion soup. Putting onion soup mix on steak is such a genius idea. Definitely going to try that!

  2. I use onion soup in a ton of recipes of mine. Never thought about making it from scratch! Might just have to give this a try!

  3. The yield at the top of the recipe says 8 tablespoons and at the end it says the whole recipe yields one packet of onion soup mix, but when I search online I see most sites say that a packet of onion soup mix has about 3 tablespoons. Any thoughts on this volume discrepancy? Thanks.

    1. I see what you mean. When you make the recipe, it will make about 8 tbsp of the onion soup mix. I am not at home to test the amounts again but I will soon and get it updated with a final number. But 1/4 cup is already about 4 tbsp so the 1/4 cup of minced onion puts it over the 3 tbsp in a normal packet of onion soup mix. Since the amounts are already small, it may be hard to cut it down, so you can always make this amount and store it in a glass jar to use later. Just make sure to give it a shake or stir before using to mix it up again.
