That little packet of French onion soup mix sitting in your pantry is doing a lot more work than most people realize.
It’s the shortcut behind that famous sour cream dip at every potluck, the secret in a really good pot roast, and the base of a bowl of soup you can throw together on a busy weeknight.
Once you make your own French onion soup mix at home, you will probably never buy the little envelopes again.
It takes about five minutes, uses ingredients you likely already have, and tastes just as rich and savory as the store bought version, minus the extra fillers and sodium you can’t pronounce.
I started making this when I noticed how often I reached for a packet of the store bought stuff, only to realize I was out.
Now I keep a jar of this mix in my pantry at all times, and I use it constantly.

If you have never tried the vegetarian route with this flavor profile, my Vegetarian French Onion Soup Recipe is a great one to try next, since it leans on the same deeply caramelized onion flavor without the beef base.
Ingredients
This recipe comes together with just a handful of dried ingredients, all measured into one bowl and stirred together.
Nothing here needs to be cooked first, so prep is basically just measuring and mixing.
- 1 cup dehydrated minced onion
- 4 teaspoons beef bouillon granules (or 4 crumbled beef bouillon cubes)
- 1 teaspoon celery seed
- 1 teaspoon onion powder
- 1 teaspoon garlic powder
- 1/2 teaspoon ground black pepper
- 1/4 teaspoon paprika
- 1/4 teaspoon ground turmeric (optional, for color)
For the full soup, or for a batch of French onion dip, you will also want sour cream, water, or beef broth on hand, though those aren’t part of the dry mix itself.
For a similar shortcut used in a cold weather braise, take a look at my Slow Cooker French Onion Soup Recipe, which uses this same base flavor.
Kitchen Equipment Needed
You really don’t need much for this one. A bowl, a measuring spoon, and something airtight to store the finished mix in are all that’s required.
- Medium mixing bowl
- Measuring spoons and measuring cup
- Whisk or fork for combining
- Airtight glass storage jars for keeping the mix fresh

Recommended Products for This Recipe
These are a few products I personally use and recommend when I make this mix, based on what has actually made the process easier or the results better in my own kitchen.
1. McCormick Beef Bouillon Granules
This is the bouillon I reach for most often because it dissolves cleanly and gives the mix that deep, savory backbone without tasting artificial.
A good quality bouillon makes a bigger difference here than people expect, since it is doing most of the flavor work.
2. Freeze Dried Minced Onion
Freeze dried minced onion rehydrates faster and tastes fresher than some of the cheaper dehydrated versions on grocery store shelves.
It also has a milder bite, which keeps the mix from turning bitter if it sits in liquid for a while.
3. Glass Airtight Spice Jars with Labels
Since this mix keeps for months, storing it properly actually matters.
These jars seal tightly enough to keep moisture out, and the labels make it easy to tell your onion soup mix apart from every other spice blend in your cabinet.
4. Simply Organic Celery Seed
Celery seed is easy to skip, but it adds a subtle savory depth that rounds out the onion and beef flavors.
A good organic version tends to be more potent, so you need less of it to notice the difference.
This mix pairs especially well with heartier dishes too, like my Air Fryer Onion Rings Recipe, if you’re building out a full comfort food dinner around this flavor.
Step-by-Step Instructions: How to Make French Onion Soup Mix
1. Gather and Measure Your Ingredients
- Pull out your dehydrated minced onion, beef bouillon granules, celery seed, onion powder, garlic powder, black pepper, paprika, and turmeric if you’re using it.
- Measure each ingredient carefully using measuring spoons and a measuring cup, since this is a spice blend and the ratios matter for getting that familiar flavor.
- If your beef bouillon is in cube form rather than granules, crumble the cubes finely with your fingers or the back of a spoon before measuring.
2. Combine the Dry Ingredients
- Add the dehydrated minced onion, beef bouillon granules, celery seed, onion powder, garlic powder, black pepper, paprika, and turmeric to your mixing bowl.
- Whisk everything together thoroughly, making sure the bouillon granules get distributed evenly throughout the onion flakes rather than clumping in one spot.
- Keep whisking for about 30 seconds to a minute, until the mixture looks uniform in color with no visible clumps of any single ingredient.
3. Break Up Any Clumps
- Check the bottom of the bowl for any stubborn clumps of bouillon granules that may not have broken apart during mixing.
- Use the back of a spoon to press and break apart any clumps you find, then whisk again briefly to redistribute them.
- A smooth, evenly distributed mix will dissolve more consistently when you use it later in soup or gravy.
4. Store the Finished Mix
- Transfer the finished onion soup mix into an airtight glass jar or a sealed container.
- Label the jar with the date you made it and store it in a cool, dark pantry or cabinet away from heat and direct sunlight.
- When a recipe calls for one packet of store bought onion soup mix, use 3 tablespoons of this homemade blend as the equivalent swap.
Once you have a batch ready to go, you’ll find plenty of uses for it in dishes like my French Onion Beef Short Rib Soup Recipe, which leans hard on this exact flavor base.
Tips for The Best French Onion Soup Mix
A few small details make a real difference in how this mix turns out and how well it holds up in storage.
- Use dehydrated minced onion rather than fresh onion flakes, since fresh onion introduces moisture that shortens shelf life
- Crumble bouillon cubes as finely as possible if you’re not using pre made granules, to avoid uneven clumps
- Double or triple the recipe if you go through this mix quickly, since it stores well for months
- Keep the jar away from steam and heat, meaning not right next to your stove
- Taste test a small batch of soup with your mix before committing to a big pot, so you can adjust salt to your preference
This same batching approach works well for other pantry staples too, like the beefy base in my Slow Cooker Beef Stew with Onion Soup Mix.
Serving Suggestions
The most obvious way to use this mix is stirred into hot water for a quick bowl of soup, but it earns its keep in a lot of other dishes too.
Stir 3 tablespoons into a cup of sour cream for a classic party dip, or sprinkle it over a roast before it goes into the slow cooker.
- Whisk into sour cream for a classic onion dip at your next gathering
- Sprinkle over a beef roast before slow cooking for deep, savory flavor
- Stir into ground beef for meatloaf or burgers for an easy flavor boost
- Add to gravy for a richer, more savory finish
- Toss with roasted potatoes or green beans before roasting
It pairs beautifully with a hearty Pot Roast with Potatoes and Carrots for a full Sunday dinner spread.
Variations of French Onion Soup Mix
This base recipe is easy to adjust depending on what you’re using it for or what you have on hand.
- Low sodium version: use a sodium free bouillon and cut back slightly on any added salt
- Gluten free version: double check your bouillon brand, since some contain hidden gluten fillers
- Spicier version: add a pinch of cayenne or extra black pepper for more heat
- Herbier version: stir in a bit of dried thyme or dried parsley for extra depth
- Vegetarian version: swap the beef bouillon for a vegetable bouillon of equal strength
If you want to see the vegetarian swap in action in a full recipe, my Slow Cooker Pot Roast Recipe is easy to adapt using that same substitution.
Storage and Reheating
Since this is a dry mix rather than a cooked dish, storage is refreshingly simple and there is no reheating involved at all.
- Store in an airtight jar or container at room temperature
- Keep in a cool, dark spot like a pantry cabinet, away from your stove or oven
- Use within 6 months for the best flavor, since dried spices lose potency over time
- Label your jar with the date made so you can track freshness
- Once made into soup or dip, refrigerate leftovers and use within 3 to 4 days

Health Benefits of Key Ingredients
This is a seasoning blend rather than a health food, but a few of the ingredients do bring some genuine benefits to the table.
Onions in particular have been studied for their antioxidant content, and garlic and black pepper both carry a long history of use in traditional cooking for their beneficial compounds.
- Dehydrated onion retains much of the antioxidant content found in fresh onion
- Garlic powder contains compounds associated with heart health support
- Celery seed has traditionally been used to support digestion
- Black pepper may help improve the absorption of certain nutrients in a meal
- Making your own mix lets you control sodium levels more precisely than store bought packets allow

FAQs About French Onion Soup Mix

Three tablespoons of this homemade blend is equivalent to one standard store bought packet of French onion soup mix.
You can measure it out this way for any recipe that calls for a packet by name.
2. Is this recipe gluten free?
It can be, as long as you choose a bouillon brand that is labeled gluten free.
Some bouillon products contain hidden wheat based fillers, so always check the label carefully.
3. How long does this mix stay fresh?
Stored in an airtight container in a cool, dark spot, this mix stays fresh for up to 6 months.
After that point it won’t spoil, but the flavor will start to fade.
4. Can I use this to make French onion dip?

Simply stir 3 tablespoons into a cup of sour cream and chill for at least an hour before serving.
5. Can I make a low sodium version?
