Dry Onion Soup Mix
We have all been there: you’re midway through making a meatloaf or getting ready to host a party with chips and dip, and you realize you are out of that little blue box of onion soup mix. But what if I told you that the best version of Dry Onion Soup Mix isn’t found in the soup aisle, but right in your own spice cabinet? Making this pantry staple from scratch is one of those “lightbulb moments” that changes the way you cook forever.
This homemade blend is everything you love about the classic packet—savory, salty, oniony, and deeply comforting—but without the MSG, preservatives, or unpronounceable anti-caking agents. It takes less than five minutes to whisk together, and the flavor is cleaner, fresher, and infinitely more potent. You control the sodium, you control the quality, and you never have to worry about running out again.
Whether you are seasoning a Sunday pot roast, whipping up a last-minute dip for unexpected guests, or adding a savory kick to roasted potatoes, this mix is your secret weapon. It’s a small jar of magic that adds instant “umami” to just about anything savory.

Ingredients
Here is everything you need to build your own savory seasoning blend.
| Ingredient | Quantity | Notes |
|---|---|---|
| Dried Minced Onions | 3/4 cup | Also called “onion flakes.” These provide the essential texture and strong onion flavor found in the classic mix. |
| Beef Bouillon Granules | 1/3 cup | This gives the mix its savory, meaty depth. Use granules or powder; if using cubes, crush them finely. |
| Onion Powder | 4 tsp | Adds a concentrated, pungent onion flavor that permeates the dish more evenly than flakes alone . |
| Paprika | 1/2 tsp | Adds a subtle sweetness and a warm reddish hue to the mix. |
| Celery Seed | 1/4 tsp | A tiny amount adds a surprisingly essential earthy, savory note. |
| Dried Parsley | 1 tsp | For a pop of green color and a hint of herbal freshness . |
| Black Pepper | 1/2 tsp | Freshly ground is best for a little spicy kick . |
| Garlic Powder | 1/2 tsp | Optional, but highly recommended for an extra layer of savory flavor |
| Sugar | 1/4 tsp | Optional; a pinch helps balance the saltiness and mimics the caramelized flavor of real onions |
Step-by-Step Instructions
1. Gather Your Spices
Pull all your ingredients out of the pantry. Ensure your beef bouillon is fresh—if it has clumped into a hard rock in the back of your cupboard, it’s time to buy a new jar for the best flavor.
2. Combine Ingredients
In a small mixing bowl or a glass jar (a mason jar works perfectly), combine the dried onion flakes, beef bouillon granules, onion powder, paprika, celery seed, parsley, and black pepper.
3. Whisk or Shake
If using a bowl, use a small whisk to blend everything until the powders are evenly distributed among the onion flakes. If using a jar, seal the lid tightly and give it a vigorous shake until the mixture looks uniform.
4. Store or Use
Seal the container tightly. Label it with the date (it lasts for months!). Use it immediately in any recipe calling for an envelope of onion soup mix.
Tips for Success
- The Magic Ratio: To replace one standard 1-ounce envelope of store-bought soup mix, measure out approximately 3 to 4 tablespoons (or about 1/4 cup) of your homemade blend.
- Crush the Celery Seed: If you want to release more flavor, lightly crush the celery seeds with the back of a spoon or a mortar and pestle before adding them to the mix.
- Check Your Bouillon: The saltiness of this mix depends entirely on your brand of bouillon. If your bouillon is very salty (like Wyler’s or Knorr), skip any additional salt in the recipe you are cooking.
- Vegetarian Option: Simply swap the beef bouillon for a high-quality vegetable bouillon or mushroom bouillon powder to make a rich, meat-free version.
- Shake Before Using: The fine powders (onion powder, bouillon) tend to settle to the bottom of the jar over time, so always give the jar a good shake before measuring.
How to Use It
This mix is incredibly versatile beyond just making soup.
- Classic Onion Dip: Mix 1/4 cup of this blend with a 16-ounce container of sour cream. Let it chill in the fridge for at least an hour to let the onions soften and flavors meld.
- Juicy Burgers: Knead 2 tablespoons of the mix into 1 pound of ground beef before forming patties for an instant flavor explosion.
- Roasted Potatoes: Toss cubed potatoes with olive oil and 2 tablespoons of the mix, then roast at 400°F until crispy.
- Savory Rice: Add 1 tablespoon of the mix to the water when cooking white or brown rice to turn a boring side dish into a savory pilaf.
- Pot Roast: Rub a chuck roast with the mix or sprinkle it over the meat in your slow cooker for a rich, savory gravy base.
Storage & Shelf Life
- Pantry Storage: Store your Dry Onion Soup Mix in an airtight jar or container in a cool, dry place (like your spice cabinet).
- Shelf Life: Since all the ingredients are dried, this mix will stay fresh for 6 months to a year. However, for the best potency, try to use it within 6 months.
- Humidity Warning: Moisture is the enemy here. Keep the lid tight to prevent the bouillon and onion powder from clumping together into a solid block.

Common Mistakes to Avoid
- Using “Better Than Bouillon” Paste: This recipe requires dry bouillon granules or powder. Do not use the wet paste, or the mix will clump and spoil in the jar.
- Forgetting to Label: It looks a lot like other spice blends once it’s in a jar. Label it clearly with the “3 tablespoons = 1 packet” conversion so you don’t forget later.
- Over-Salting: Because beef bouillon is already salty, do not add extra salt to this mix unless you are using a sodium-free bouillon base.
- Not Rehydrating: When using this for dip, remember that the dried onions need time to absorb moisture. Don’t serve the dip immediately; let it sit for an hour so the onions lose their crunch.
FAQ
Is this gluten-free?
It depends on your bouillon. Many beef bouillon brands contain gluten (barley) or wheat fillers. Look for a bouillon labeled specifically “Gluten-Free” to ensure this mix is safe for Celiacs.
Can I use fresh onions?
No, this recipe is for a dry pantry staple. Fresh onions would cause the mixture to mold if stored in a jar.
How much mix equals one store-bought packet?
One standard envelope of Lipton or generic onion soup mix contains about 1 ounce of powder. This is roughly equivalent to 3 to 4 tablespoons (or a scant 1/4 cup) of this homemade recipe.
Can I make actual soup with this?
Yes! To make a quick broth or soup base, add 3-4 tablespoons of the mix to 4 cups of boiling water. Simmer for 10 minutes to soften the onions.
Why does my mix look different than the store version?
The store version often uses caramel color and cornstarch to make it look darker and thicker. Yours is natural! If you want a thicker soup, you can add a pinch of cornstarch when you cook with it.

Making your own Dry Onion Soup Mix is one of those small kitchen victories that pays off big time. It’s healthier, cheaper, and tastes so much better than the preservative-laden packets.
