How to Make Homemade Low-Sodium Onion Soup Mix Recipe
Step 1: Combine the Dry Ingredients
Start by gathering all your dried herbs and powders in a bowl. Mixing them dry ensures every flavorful spice infuses evenly throughout your mix. This step lays the foundation for a well-balanced, homemade seasoning that feels fresh and lively.
Step 2: Blend for Uniformity
Once combined, give the ingredients a good stir or whisk until the mixture looks consistent in color and texture. This simple action guarantees that each spoonful of your mix will deliver the perfect blend of onion, herbs, and spices—no clumps or uneven pockets of flavor.
Step 3: Store Properly
Transfer your homemade mix to an airtight container or jar. Keeping it sealed preserves all the aromatic qualities and ensures your mix stays fresh and potent for weeks. Label it with the date so you remember when you made it!
How to Serve Homemade Low-Sodium Onion Soup Mix Recipe

Garnishes
Sprinkle a little of your onion soup mix on top of roasted vegetables or mashed potatoes for an instant flavor upgrade. It also works beautifully as a seasoning for dips or sprinkled over freshly baked breads before serving.
Side Dishes
This mix pairs wonderfully with simple side dishes. Toss it with steamed green beans or carrots, or stir it into wild rice or quinoa for added zest and aroma. Its low-sodium profile means you can use it liberally without worrying about over-seasoning.
Creative Ways to Present
Try mixing your Homemade Low-Sodium Onion Soup Mix Recipe with sour cream or Greek yogurt for a quick and tasty dip. It’s also fantastic blended into meatloaf or burger blends to infuse a rich, savory taste without relying on salt.
Make Ahead and Storage
Storing Leftovers
The great news is that your homemade onion soup mix keeps exceptionally well. Store it in a cool, dry place away from sunlight, and it will maintain its vibrant flavor for up to three months. Just make sure the container is airtight to prevent moisture from creeping in.
Freezing
Freezing your soup mix is usually not necessary since it can easily be stored at room temperature. However, if you plan to make a larger batch to save extra time, freezing in a sealed, freezer-safe container can extend its shelf life even further without loss of flavor.
Reheating
This mix doesn’t require reheating since it’s a dry seasoning blend. When you use it in soups or other cooked dishes, just add it during the cooking process to allow the flavors to meld beautifully.
FAQs
Can I use fresh onions instead of dried onion flakes?
Fresh onions will add moisture and a different texture, so for the purpose of this dry soup mix, dried onion flakes are best. They provide longevity and consistent flavor without altering the mix’s shelf life.
How can I reduce bitterness if I don’t like strong black pepper?
If you prefer a milder flavor, simply decrease the amount of ground black pepper, or omit it entirely. The mix will still maintain a wonderful depth of flavor thanks to the herbs and garlic powder.
Is turmeric necessary in this recipe?
Turmeric is optional and mainly added for its vibrant golden color and subtle earthiness. If you’re not a fan or don’t have it on hand, feel free to leave it out without compromising much on taste.
Can this mix be used for other recipes besides soup?
Absolutely! This mix shines as a seasoning for roasted vegetables, dips, meat dishes, and even as a salad dressing enhancer. Its versatility is one of the reasons it’s such a favorite to have on hand.
How do I adjust this recipe to make a larger batch?
Simply multiply the ingredient quantities by your desired number of servings. Just maintain the ratios to keep the flavor balanced. Storing the larger batch properly ensures it remains fresh and ready whenever you need it.
