Making your own gluten-free onion soup mix is easy to do – and completely possible for even the novice cooks out there. When you make your own mix, you know it will be gluten-free and MSG-free too. I added the MSG part because did you know that the leading onion soup brand is NOT gluten-free AND contains MSG? What in the world was I feeding my family before my Celiac diagnosis!?!?
As many home cooks know, onion soup mix is a key ingredient in a plethora of recipes you’ll find online and in cookbooks. It flavors any dip or meat dish well and is a kitchen staple. I use it regularly to make a family favorite recipe, Cranberry-Orange Glazed Chicken.
If you’d like to make your own onion soup mix, I suggest you buy all the ingredients and make 6 or more bags for the year. This stuff keeps well in a sealed baggie. Then, when you need it, you don’t have to make it from scratch.
These are the bullion cubes (affiliate link) I use:
- 4 tsp. dried beef bouillon (or two Not-Beef Bouillon Cubes by Edward & Sons - love this stuff!) - check labels to ensure bouillon is gluten-free
- 2 Tbsp. dried onion flakes
- 2 tsp. onion powder
- 1/2 tsp. garlic powder
- 1/4 tsp. pepper
- 1/4 tsp. celery salt
- In a large mixing bowl, combine all ingredients. If using the Not-Beef cubes, you'll want to crush the cubes in the baggie by hand or in a bowl with a fork (the texture will be soft, just crush as best as you can).
- Store in a Ziplock bag until needed.
