Need a quick onion soup mix substitute without running to the store? This homemade onion soup mix comes together in minutes with pantry staples and works anywhere you’d use a packet of French onion soup mix.
From dip and meatloaf to pot roast, gravy, and soup, it’s one of the easiest pantry shortcuts to keep on hand. It’s savory, onion-y, customizable, and honestly tastes better than the boxed stuff. Just 3 tablespoons of a dry onion soup mix replaces 1 store bought packet.
What Is Onion Soup Mix?
Onion soup mix is a dry seasoning blend made with dried onion, bouillon, and spices. Even though it’s called “soup mix,” it’s commonly used to season pot roast, meatloaf, dips, gravies, roasted vegetables, and casseroles.
Why You’ll Love It
This seasoning secret will add a savory note to lots of dishes. Here are a few reasons why we love it:
- Ready in 3 minutes – Faster than a grocery run and made with pantry staples.
- Works like a packet – Use it anywhere a recipe calls for dry onion soup mix or French onion soup mix.
- Big savory flavor – Onion flakes, bouillon, and spices give it that classic cozy, beefy, onion-forward taste.
- Easy to customize – Make it lower sodium, vegetarian, smoother for dip, or extra onion-y.
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 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 – It adds to the tasty broth flavor.
- Parsley flakes – Optional, but adds color and a little herb flavor.
- Celery salt – If you’d really like to step up the flavor, you can substitute this for celery seed instead. This ingredient is also salty which is why I warn about using too much salt in other areas.
- Smoked paprika – Adds subtle warmth and smoky depth; regular or smoked paprika works too.
- Salt and pepper – I prefer to use freshly ground black pepper and fine sea salt, but use sparingly!
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
Homemade onion soup mix is one of the easiest ways to add savory flavor to weeknight meals. Here are some of my favorite ways to use it:
- Stir it into sour cream for an easy French onion dip.
- Sprinkle it over pot roast before slow cooking.
- Mix it into meatloaf so every bite has savory onion flavor. Here is my onion soup mix meatloaf recipe with an onion soup gravy too.
- Add it to burger patties for an easy flavor boost.
- Toss it with potatoes before roasting. Here is my favorite recipes for Lipton Onion Soup Mix Potatoes.
- Season vegetables like green beans, carrots, or Brussels sprouts.
- Whisk it into gravy for extra depth.
- Use it as a soup starter with broth and caramelized onions.
- Rub it onto pork chops or chicken before cooking. We love our onion soup grilled pork chop recipe.
- Mix it into mashed potatoes for a sneaky little flavor upgrade.
- Add it to casseroles when they need a little help in the flavor department.
Chef Tips
Use minced dried onion, not onion powder alone. You need both. The flakes bring that classic packet texture, while onion powder fills in the background flavor.
Pulse it for dip. If you want a smoother French onion dip, blitz the mix for a few seconds in a spice grinder so nobody gets a giant onion flake ambush.
Watch the salt. Bouillon brands vary wildly. Taste your mix before using it in meatloaf, gravy, or soup.
Bloom it in liquid. Let the mix sit in broth or sour cream for 5–10 minutes before serving so the dried onion softens and the flavor rounds out.
Double the batch for gift jars. Great as a hostess gift, print out fancy labels with the instructions to make soup and tie with pretty ribbon.
For true substitute performance, write your recipe by packet equivalent. Use 3 tablespoons for every 1 packet in a recipe.
How to Make it Into Soup
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. Top it with a piece of crusty bread, croutons and cheese to make it into a quick French onion soup.
How to Store French Onion Soup Mix
Store in an airtight container in a cool, dry place for up to 6 months for best flavor. It can last longer, but the seasonings start to lose potency over time.
Onion Soup Mix FAQs
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.
Yes. Use chicken or vegetable bouillon instead. Vegetable bouillon is the best choice for a vegetarian onion soup mix substitute.
Store in an airtight container in a cool, dry place for up to 6 months for best flavor. It can last longer, but the seasonings start to lose potency over time.
Absolutely. Mix 3 tablespoons with 16 ounces sour cream, then chill for at least 30 minutes before serving.

I mix it in sour cream with a few splashes of soy sauce for a French onion dip. It’s amazing and no unwanted ingredients from the store bought dry mixes.
Is parsley and celery necessary?
They add flavor- but totally up to you!
I needed a recipe for gluten free onion soup mix and this is perfect. I use it all the time when a recipe calls for onion soup mix.
Thank YOU for coming bak to let us know- glad we could help!

What is the approximate size of the serving when you say the recipe makes 4 servings?
Sure! One tablespoon of dry mix and 1 cup of prepared if you are actually using it to make soup.
I made this today since I was out of the store bought Lipton soup mix, only thing I didn’t have was parcely so I used chives in its place. I was going to make a meat loaf but decided it was way to warm outside and inside so I made hamburger steaks for the hubby for Father’s Day. They were delicious.
Love this recipe! Can you tell me how long this can be stored for?
Love this
This was awesome, I made it just as instructed. I use this in my hamburger mix for burgers! I got 6 Tbsp from this mix but I didn’t see listed what to expect . I am assuming we can make ahead and keep in an air tight container
Thank you, I am a new subscriber to your page and can’t wait to see what else you have put there!
Soooo good! I love this recipe and will make it again!
