Whole30 French Onion Seasoning Mix

Our Whole30 French Onion Seasoning Mix is an easy way to infuse a lot of flavor instantly. It’s quick to make and budget-friendly. Unlike the onion soup mix packets found at the store, you can control everything that goes into it. This ensures your seasoning mix is Whole30 compatible, gluten-free, and dairy-free—a delicious flavor base for soups, casseroles, or roasts.

This French onion seasoning mix is grounded in basic pantry spices and herbs. We use dried minced onion flakes, onion powder, garlic powder, parsley, salt, and pepper. You can find these in the spice aisle; some stores even have the option to buy spices in bulk bins at a lower price.

The ingredient that gives it a full, deep flavor is beef bouillon powder. However, most beef bouillon powders aren’t Whole30 compatible due to added sugar or non-compatible additives. Check your labels closely! We loved using Whole30 Approved Bare Bones Broth Instant Bone Broth for this bouillon powder. But you are welcome to use whatever is accessible and compatible with the Whole30 program.

Can’t find a compatible beef bouillon or need a plant-based option? Beef bouillon is dried beef broth granules. So, if you can’t find any, you can use this mix plus 1 cup of beef broth or bone broth in your recipe to achieve a similar flavor profile. Keep in mind to adjust the liquid in your recipe accordingly if using the broth. Or another option is to use an equal amount of a compatible umami seasoning. This keeps the rich flavor depth but also makes it vegan and plant-based!

This Whole30 French Onion Seasoning Mix recipe is equivalent to one onion soup mix packet or five tablespoons of mix. It stores great in the pantry in a sealed container (we used a small mason jar with a lid) for up to 3 months. Feel free to double or triple the recipe to have plenty on hand as needed!
