Homemade Onion Soup Mix – Gluten Free!

Gluten Free Onion Soup Mix
I use a lot of onion soup mixes in my recipes, especially when I’m throwing something in the crock pot. I’ve been using Lipton’s boxed ones for years, and never had a problem with the ingredients, even though they don’t specifically say they’re gluten free. However, the more we eat clean in our house we’re noticing sensitivities to other things like salt content. So I’ve went on a mission to create our own soup mixes, using whole ingredients and reducing the amount of processed ingredients. This is similar to my gluten free condensed soup mix – it’s quick and easy and I keep it in a jar on hand on my counter.

Gluten Free Onion Soup Mix

To make this recipe I dried my own onions, celery and mushrooms with my dehydrator. You can used dried onions from the store for this – it would be a lot quicker. But by dehydrating the vegetables myself I was able to customize this recipe for what I like to put in recipes. You can change the recipe however you want!


  • 3/4 cup dried Onion mixture (or onion flakes)
  • 3 Tbsp beef bouillon (or 3 cubes crushed) – You can use Chicken for chicken recipes too! Use gluten free if you want this to be gluten free!
  • 4 tsp onion powder
  • 1/4 tsp celery seed
  • 1/4 tsp sugar
  • 1 tsp white rice flour


  1. Mix all ingredients in a small bowl and put in a jar to use later!
  2. 5 Tbsp will be the same as 1 store bought package!

See – super easy! Now I made a quadruple batch and made it’s half chicken base and half beef base, so I have it for the recipes coming up.

This recipe will make about 4 packages of store bought mix!

My vegetable mixture (before drying) was 3 stalks of celery, 3 large onions and 2 lbs of fresh mushrooms. They ended up to larger pieces so I pulsed them in the the food processor until they were smaller and some powder was mixed in. After processing it made about 3 cups of dried vegetable mixes.

Storing Homemade Soup Mix

How to Store: 

I prefer to store mine in mason jars. I picked up more of the Ball Heritage blue pint jars – I absolutely love them. But I wanted it to be air tight so they will last for months to come. So I picked up a jar sealer for my hand held food saver. Simply slide it on top once you place the lid on, suck the air out and it will seal it for you! This helps add shelf life to your dry goods so they wont get spoiled by moisture! Super easy and great for making large batches to keep your shelves stocked!
