Make your own homemade dry onion soup mix to keep on hand to flavor dips and main dish recipes.

chips and onion dip made with onion soup mix

Sour Cream and Onion Dip is one of my weaknesses. And even though not all my people love sour cream as a topping, they go wild for the dip. I’ve developed a couple different recipes for sour cream dips, but for this DIY Convenience series, I decided to try for a dry mix that you could keep on hand, using all shelf-stable ingredients.

That’s what I used to use when I was in high school and first learning to cook. Dry packaged onion soup mix was a go-to for pot roast, stew, meatloaf, and of course, sour cream dip. I don’t think we ever used it as a soup, but it was mighty fine mixed into things as a seasoning.

It was also pretty chock-full of junky ingredients, excessive sodium, and weird stuff I can’t pronounce, even with a graduate degree.

Making my own homemade onion soup mix sounded like the way to go. And it was tasty! I mixed it into dip, stewed it with pot roast, and stirred it into meatloaf. All I can say: Super Yum. The dip was flavorful, the roast well seasoned, and the meatloaf? Pretty awesome.

There are probably more ways to use this mix. Try it out in your favorite recipe that calls for commercial soup mix and let us know how it works out. 

Homemade Onion Soup Mix ingredients in a bowl

What’s onion soup mix made of?

When you’re making your own homemade onion soup mix you get to choose what’s in it! Unlike those store-bought versions. Here’s what in my homemade version:

  • dry onion flakes
  • kosher salt
  • dried thyme
  • paprika
  • dry mustard
  • garlic powder
  • black pepper

Making dry onion soup mix yourself.

This was a super easy process. Just mix dry seasonings together and voila!

Please note that you will probably not need a one-to-one substitution for the dry mix. I’m going to bet that my version is more strongly flavored. Less is more, you know?

To make onion dip:  I used 1 to 2 tablespoons of the mix to 1/2 cup sour cream

To use with meat: a few tablespoons over a pot roast; and a couple tablespoons in meatloaf.

What do you eat with onion dip?

This onion dip is great served with potato chips. You can keep it simple and buy some chips or make your own homemade potato chips. If you want to keep it a bit healthier, then serve it with a veggie tray.

Onion dip is also delicious with french fries and baked potatoes!

How long can you keep onion dip in the fridge?

Prepared food is good in the fridge, covered, for up to 4 days.

Since this is a dip that might tempt double-dipping, consider serving it in single-serve cups or provide a spoon so folks can dish out a bit on their plates. This is better food safety and it will help your dip stay good longer.

How to make this dish inexpensively

All of my recipes are affordable to begin with but there are some things you can do to make sure you’re spending well. Here are some of the strategies you can use to make this recipe more economical:

  1. Thank you! I was just wondering how to make this tonight since my husband’s food allergies make it hard for us to eat packaged products.

    • Great! I’d love to hear what recipes you use it in. I tested meatloaf, roast, and dip, but I’m sure there are lots of other options.

      • Lauren Eicher says

        Turkey burgers! Take 1lb ground turkey and add onion soup mix, a handful of plain bread crumbs, a drizzle of olive oil, salt and pepper. Form into patties and grill. Delicious and so flavorful!

  2. I have a weakness for sour cream and onion dip, too! We always just call it French onion chip dip, but it’s the same thing.

    The difference is, I toss this under my “it’s so cheap and easy, just buy it instead of making it yourself” list, though, ha. Yes, it might be a tiny bit cheaper to make it myself, but I don’t really see many health benefits (I already only buy brands that don’t use MSG because of a family allergy) and realistically, I’m tossing it into sour cream and dipping chips into it anyway….can’t get much unhealthier than that! I’d end up having to buy new jars of most of the spices to make a decent sized batch, too, and then I just now I’d talk myself into using onion dip even more often because well, I’d already have it on hand, lol. It’s probably best I avoid that.

  3. Hey! Thanks! I was so happy to see this pop up in my email. I have a veggie soup recipe that we enjoy that calls for a packet of onion soup mix. I tried making it without the packet the last time and it just wasn’t the same. Can’t wait to try this!

  4. holly says

    Are onion flakes the same as dehydrated onions? I’m looking forward to trying this!

  5. Kirstin says

    What kind of thyme do you mean? Isn’t there ground thyme and, I guess, dried thyme?

  6. Lee says

    We tried a new seasoning mix that was supposed to
    Serve as “onion soup packet” last week and we were so disappointed. As I am looking through your ingredients and they are completely different from the other one I tried, different enough that I think I am willing to try again. :).

    • Well, I hope this one works better!

    • Elaine says

      The original Lipton uses TOASTED onion flakes which are available from myspicesage.com. It does make a difference in taste! I found this out from trying to make this recipe years ago and it was never right until i found the toasted onion flakes. I do not work for or get any money from my spice sage.

  7. Melissa says

    Another addition some of you might like is beef bouillon granules – it adds a little depth to the flavor. You could leave out the salt if you choose to add the granules.

    • Yep, that would be great. I haven’t found a product that I liked in terms of healthy ingredients at a price that made sense. Do you know of one?

      • jck says

        I like the jars of low sodium “Better than Bouillon” but they can only be used dissolved in liquid.

        • Jen says

          Jess, how much onion flakes? 1/4 cup I’m guessing, right?

          • Yes, sorry. I’m recoding recipes to a new code and apparently made a mistake. 1/4 cup

  8. Sandi says

    Similar to the meatloaf, it really enhances homemade hamburger patties. I do not think I’ve used it for anything else other than what you listed. I’ve actually not even used it at all in probably 8 years. I frequently sub greek yogurt for sour cream since it is a similar consistency and much healthier. I’m wondering how this dip would come out with yogurt? The tang might actually blend in pretty nicely. Maybe I need some dip in the future. Oh wait, I don’t have any fresh veggies or chips. Never mind. 🙂

  9. Heather M says

    Oh my! Onion dip is my worst weakness ever. I’ve been known to polish off an entire batch of it for lunch. And it is AWFUL for you in the packaged form(although I make it w/light sour cream… but oh, the sodium!). I’ve had to swear it off. I’m really excited to try this blend out! Will eat it with raw veggies though, since I’m eating healthier these days. Thanks for a new inspiration!

  10. Claire says

    My boys are gonna love this when I make it!!!!!

  11. Emily says
    • Let us know how it works for you! (Holding my breath. I’ve never made a roast with soda pop.)

      • Charity L. says

        I make Dr. Pepper pulled pork in the slow cooker. It is awesome!

  12. Mel says

    I love chips and onion dip so much! Here in New Zealand we mix the onion soup mix with a can of reduced cream (do you get that over there?) and a squeeze of lemon juice and then chill it for 30 minutes. Divine!
    (And then we get a packet of chips, commence dipping and devour the whole lot and by we I mean me because I don’t share well!)

  13. Cari says

    Sounds wonderful. Thank you!

  14. Maria says

    This is gluten free! I loved to use onion soup mix for lots of stuff til I learned I was allergic to wheat. Wheat is in the packaged onion soup mixes. I’m so glad I found this and cant wait to try it!

    • Using it for French Dip sandwiches as we speak. Coating the roast with it and then crockpotting it. 🙂

  15. Elizabeth says

    This mix was fantastic! I have a weakness for chips and dip…I ate a whole batch of dip and bag of chips myself. Can’t wait to try this in other recipes calling for the onion soup mix, like slow-cooked French dip sandwiches.

  16. Barbara says

    In South Africa commercial dry soup mixes are sold as “packets” of soup (eg. a 55g brown onion soup packet, a 65g white onion soup). Each packet makes 4 servings of soup by adding 850ml of water. How many servings of soup does the above recipe make (and how much water would I add). Also, can anyone tell me what an “envelope” weighs in grams and how many servings does it make?

    • I have not tested this as a “soup” but as a mix to be used in other recipes, like dips, casseroles, and roasts.

    • Karen says

      I’m in Canada, and we have similar dry soup mixes to the onion recipe here. I haven’t bought the commercial version in years so don’t have weights handy, but am quite sure they all make four servings. I think they all stated to add 2 cups of water, which would be about 500 ml.

  17. TSandy says

    Thanks for another great recipe. I have totally quit buying prepackaged mixes because of the cost and all the preservatives in the mixes. My husband will love this recipe.

  18. Melissa says

    I had mentioned beef bouillon granules a year ago – they do make a low sodium version. I use the regular one though and leave out any additional salt.

  19. Kate says

    Thanks for posting a recipe that omits beef bouillon! Trying to keep MSG out of the house.

  20. Steve F. says

    FYI…..”HERB-OX” is the name of a NO SODIUM beef boullion. They also make a chicken one.

  21. Joe W. says

    I use this on pork loins and tenderloins oven roasted in aluminum foil. I cover the meat with olive oil then the mix, and wrap it twice in aluminum foil sealing it well. Leave some room for the juices to settle, ot they find their way out of the packet. Place the packet in an oven safe pan. I then roast them at 190-205 degrees F for about 1- 1/2 hours per pound. There may even be enough liquid to make a savory gravy. Guests love it.

  22. madelyn says

    I would love to try this, in order to get as close to the original taste as possible has anyone tried to toast the dried onions at home rather than buy them toasted? Many thanks for sharing the recipe.

  23. John says

    Since I can’t find the mix at Tesco or Marx & Spenser, here in Hampstead, UK,
    This is a handy substitute. Thanks. We use it for foundation of chicken and rice casserole.

  24. Joy says

    I use dried onion soup mix in Beef Stroganof, Oven baked Onion-Roasted Cheese Potatoes, Pot Roast, and Dip. I was making the potatoes today and wondered if there was a way to make the dried mix. So I looked it up saw yours. I think I will try it next time I make this dish.

  25. Rene says

    I hope to try this recipe with a chuck roast. I am trying to reduce using so much premade mixes so I can see what is going into my food. Thanks for posting this.
