Onion Soup Mix Recipe ingredients

The base for dry onion soup, sometimes called French Onion Soup Mix, is fairly basic. Made with simple ingredients found in your spice cabinet or easily at your local grocery store.

  • Dry onion flakes – It wouldn’t be onion soup without some onion, right? The flakes are important to add a little texture. 
  • Powdered beef bouillon – Because this is a dry mix and we need it to be shelf stable, we need beef bouillon granules, not bouillon paste.
  • Onion powder – A little more onion flavor can’t hurt! Granulated onion is less potent, but still important for the rich onion flavor.
  • Garlic powder – No good soup is made without garlic. It just adds to the tasty onion broth flavor.
  • Parsley flakes – I didn’t use these the first time I made this soup mix and took pictures, but I do like to add them sometimes.
  • Celery salt – If you’d really like to step up the flavor, you can substitute this for celery seed instead.
  • Smoked paprika – I like the smoky flavor the best, but you can certainly use regular paprika if that’s all you have on hand.
  • Salt and pepper – I prefer to use freshly ground black pepper and fine sea salt. Coarse Kosher salt is a little too coarse. 

I prefer mine to be extra onion-y (yep, I just made up that word), so I use more onion flakes than the store bought version and also add black pepper. Look for a very finely ground black pepper to make the smoothest mix.

You can even go a step further and use garlic flakes instead of onion or use both!

Using Dry Onion Soup Mix

This is probably one of the most versatile items in the kitchen for seasoning. When I say that I always have it, I’m not joking. Whether is it a homemade onion soup mix or pre bought, it is a staple. Here are a few of my favorite recipes to use it with:

For most recipes, keeping it chunky and whole is perfectly fine, but if you are looking for all of the flavor, but a fine blend without large pieces of onion, try using a spice grinder to blend it up. This is my favorite spice grinder, cheap and easy to clean! You can also use it to grind coffee!

How to make Onion Soup from an Onion Soup Mix

One of the most common questions is how to make soup from dry onion soup mix. The process couldn’t be simpler! If you want to make soup, add 4 cups of water or low sodium beef broth in a large bowl and allow to sit for 5 minutes.

Add caramelized onions, frozen veggies like green beans or even thinly sliced beef or chicken to make a whole meal. It’s sure to be a family favorite.

How to store French Onion Soup Mix

Storage: This dry soup mix is very shelf stable and will last in a cool, dry place for up to a year. Store in an airtight container like a mason jar.

Freezing: You can also store it in the freezer or fridge to preserve it a little longer. Keep in mind that like most dry seasonings, it will start to lose its potency at about 6 months.

PRO TIP: Get a few small glass containers from the craft store and make these into gifts. Print out the soup instructions on cute labels and decorate with colorful string. 

DIY Dry Onion Soup Mix FAQs

How many tablespoons equals one packet of Lipton Onion Soup Mix?

There are about 3 tablespoons in a Lipton onion soup packet, give or take a smidge. In most recipes, you can eyeball the amount and use a little more or a little less without worry of ruining the recipe.

The only thing to be mindful of is salt content. If the recipe calls for additional salt, add the soup mix and then season with salt accordingly. Adding both could make it to too salty. Same goes for recipes using broth, opt for a low-sodium broth so you can control the saltiness.

What is the difference between dry onion soup mix and french onion soup mix?

There really isn’t a difference and honestly, I don’t even use it to make French Onion Soup, only just a basic onion soup.

Questions and Reviews

  1. I’ve been making my own soup mixes like cream of mushroom. How much ingredients and water to equal 1 – 10oz can of French onion soup?

  2. 5 stars
    This was such an easy spice mix to make and store at home — we used this on roasted veggies recently and it added such great flavor to the dish!

  3. 5 stars
    This is a great recipe! Perfect for dips, soups, and I can’t wait to try it with my french onion soup pork chops!

  4. 5 stars
    I use onion soup mix for so many recipes. This homemade mix will definitely come in handy. It’s the perfect addition to my pantry.

  5. 5 stars
    Love homemade seasoning mixes… so much better (and better for you) than store bought! Can’t wait to make an onion dip with this.

  6. 5 stars
    Wonderful recipe! I’m so glad to have a homemade onion soup mix recipe. The box ones contain bioengineered food and I won’t touch that. My husband and son said this tastes better than brand in box. I used 1/4 cup to a 16oz container of sour cream. Perfect!

  7. 5 stars
    I have made this twice in one week. Tried it as a dip for chips/veggies and also used it to make meatloaf. Company coming tomorrow so I just made another batch for dip

    1. Probably a really long time! The salt is a natural preservative, so a year or so with decent flavor. The thing I would be more worried about is the dried bits starting to lose their flavor.

  8. 5 stars
    This is beyond amazing! This has opened up our menu to nee possibilities since having to go GF due to Celiac! In my opinion, this is 10 times better than the boxed onion soup mix!! Thank you !!!!!

  9. 5 stars
    There have been so many times I wanted to make something that called for dry onion soup mix which I refuse to buy. Now I can try those recipes! Thanks for figuring it out.

  10. 5 stars
    Loved the recipe!
    But to much salt. Bouillon has salt, then the celery salt and the sea salt.
    I will be using this recipe. Just leaving out the salt and use celery seeds or dryed celery flake insted.
    This makes about 2 single pkgs like in a box.
    Great tasting recipe a keeper.

    1. Thanks for the feedback~! Yep, all of those things have salt and differ in saltiness by brand. Always use a coarse kosher salt, not a fine or table salt.

  11. 5 stars
    Hi Jessica. We just found your recipe and we absolutely luv it. We’ve made different recipes trying to find a good one and yours is the best we’ve tried. We will keep this on hand to put in all of our different recipes from dip to meatloaf. Thank you so much for this one!

  12. 5 stars
    I love this soup mix. I made a quart jar of it and keep it on hand at all times. I put it in all kinds of recipes. I add it to my beans, roast, use for dip, etc. Will keep this on hand. Thanks for the recipe!!

    1. Hi Kathy- each packet is about 3 tablespoons and this recipe makes a tiny bit less than 4 pouches.
