How to Make Low-Sodium Onion Soup Mix
Step 1: Gather Your Ingredients
Start by measuring out each spice and herb for your Low-Sodium Onion Soup Mix. Mound the dried minced onion, onion powder, garlic powder, black pepper, celery seed, paprika, parsley, turmeric, and thyme onto your work surface. Prepping everything ahead ensures you won’t miss a thing and makes assembly a breeze.
Step 2: Mix Well
Combine all measured ingredients in a small mixing bowl. Give the mixture a thorough stir with a spoon or small whisk to ensure everything is distributed evenly. You want every spoonful of your Low-Sodium Onion Soup Mix to have the perfect balance of flavor!
Step 3: Store Safely
Once the mix is uniform in color and texture, transfer it into an airtight container or a glass jar with a tight-fitting lid. Label it with the date, and stash it in a cool, dry pantry spot—your homemade Low-Sodium Onion Soup Mix will stay fresh and ready to use for up to six months!
Step 4: Using the Mix
To substitute for a standard store-bought soup mix packet, simply use four tablespoons of your homemade blend. Add it directly to soups, dips, casseroles, or even as a rub for roasting veggies and meats. The best part? All that flavor magic, with only a whisper of sodium.
How to Serve Low-Sodium Onion Soup Mix

Garnishes
For soups or dips made with Low-Sodium Onion Soup Mix, a sprinkle of fresh chopped chives, extra parsley, or even crispy shallots brings brightness and texture that makes any presentation pop. Tiny lemon zest curls can also add refreshing notes without additional salt.
Side Dishes
Pair any Low-Sodium Onion Soup Mix-based recipe with fresh salads, crusty whole grain bread, or simple steamed vegetables. The mix’s savory flavor is especially delightful alongside lightly roasted potatoes or a fluffy quinoa pilaf.
Creative Ways to Present
Serve dips in a hollowed-out bell pepper or mini bread bowl for a charming twist, or sprinkle the mix onto hot popcorn for a flavorful snack. Package a batch in a cute glass jar tied with twine and tuck in a recipe card—homemade Low-Sodium Onion Soup Mix makes a thoughtful edible gift for friends watching their sodium intake.
Make Ahead and Storage
Storing Leftovers
Keep any unused Low-Sodium Onion Soup Mix in an airtight container, away from light, heat, and humidity. A jar with a secure lid works perfectly. It will easily retain freshness, fragrance, and flavor for up to six months in your pantry—just give it a little shake before each use.
Freezing
While this is a dry mix and doesn’t usually require freezing, you absolutely can portion it into zip-top freezer bags for longer storage if you’re making a large batch. It helps prevent clumping and locks in that fresh-from-the-spice-cabinet aroma for months.
Reheating
The mix itself doesn’t need reheating, but when used in a dish, simply warm your soup, dip, or casserole as you normally would. The flavors intensify beautifully as they blend into hot recipes, making every bite just as satisfying as the first.
