How to Make Low-Sodium Onion Soup Mix Recipe
Step 1: Gather Your Ingredients
Start by assembling all your herbs and spices in one place. Having everything measured and ready makes the process seamless, and you’ll notice how colorful and inviting the combination looks even before mixing.
Step 2: Mix Thoroughly
In a small bowl or airtight jar, combine the dried minced onion, onion powder, garlic powder, dried parsley, celery seed (if using), black pepper, paprika, and thyme (if using). Stir or shake well until all ingredients are evenly distributed. This ensures consistent flavor in every spoonful.
Step 3: Store Properly
Transfer your mix to a clean container with a tight-fitting lid. Store it in a cool, dry area away from direct sunlight. This homemade Low-Sodium Onion Soup Mix Recipe will stay fresh and flavorful for up to six months if kept sealed and dry.
Step 4: Use in Your Favorite Dishes
To enjoy as soup, whisk 4 tablespoons of your mix into 4 cups of low-sodium beef or vegetable broth, then simmer gently for 10 to 15 minutes. Alternatively, sprinkle 1 to 2 tablespoons into meatloaf, casseroles, or roasted veggies for a salt-conscious flavor boost.
How to Serve Low-Sodium Onion Soup Mix Recipe

Garnishes
A sprinkle of fresh chopped herbs like thyme or parsley over your prepared soup adds a fresh aroma and a lovely pop of green. For a comforting golden crust on onion soup, topping with a slice of crusty bread and melted low-sodium cheese pairs beautifully with the deep flavors of this seasoning mix.
Side Dishes
This mix shines not only in soups but also in dishes served alongside. Roasted potatoes tossed with a touch of the mix and olive oil make a perfect companion, as do steamed green beans lightly seasoned. These sides enhance the meal’s savory profile without overwhelming your palate.
Creative Ways to Present
Take your soup night up a notch by serving your onion soup in individual ramekins topped with toasted baguette slices and a sprinkle of your favorite low-sodium cheese. Beyond soup, try blending the mix into dips or sprinkling over popcorn for a surprising, salty-free treat that guests will love.
Make Ahead and Storage
Storing Leftovers
Since this is a dry seasoning blend, leftovers stored in an airtight container maintain their vibrant flavors for months. Keep your jar out of moisture to avoid clumping and to ensure your Low-Sodium Onion Soup Mix Recipe remains potent whenever you reach for it.
Freezing
There’s no need to freeze this mix because dried herbs and spices retain their flavor well when kept dry and sealed. Freezing may cause moisture buildup once thawed, so the best practice is storing it in a cool pantry spot.
Reheating
As this mix is primarily for seasoning, it doesn’t require reheating on its own. When used in soup or cooked dishes, just heat as usual—your Low-Sodium Onion Soup Mix will infuse its savory, aromatic notes without any extra effort.
