Save Recipe

I tried making onion soup mix without bouillon, but it took too many expensive ingredients to get close to that familiar flavor. This recipe keeps things simple and uses a small amount of bouillon for the savory depth we expect from onion soup mix.

Here’s Why This Onion Soup Mix Recipe Works

Simple pantry ingredients: This mix comes together with dried seasonings you can keep in the pantry, so there’s no chopping onions or extra prep.

It tastes like onion soup mix should: Beef bouillon, onion powder, and dried chives give it that familiar savory flavor without sending you off to buy a bunch of odd ingredients.

You can adjust the flavor: Make it a little lighter or a little stronger by changing the amount of bouillon, and tweak the sugar or paprika to suit your taste.

It’s handy to keep around: Stir it into sour cream for dip or use it in meatloaf, roasted potatoes, burgers, casseroles, and slow cooker recipes when you need quick onion flavor.

This mix works well in our onion soup meatloaf, where it adds that familiar savory onion flavor without opening a store-bought packet.

You can also stir it into our slow cooker beef stew for an easy way to build flavor in the broth.

For a dinner idea, try our French onion soup casserole, which brings those rich onion soup flavors to the table in an easy, crowd-friendly dish.

Homemade Dry Onion Soup Mix

Keep a jar of this homemade onion soup mix in the pantry so you have an easy substitute ready whenever a recipe calls for a packet. It mixes up fast, uses simple ingredients, and gives you that familiar savory onion flavor in dips, soups, casseroles, and other dinner recipes.

If you want to put this mix to work right away, use it in our French onion soup dip for an easy party dip or snack.

Cook ModePrevent your screen from going dark

Instructions 

• Combine all the ingredients and store in an airtight container.
• Three tablespoons is equivalent to 1 package of storebought onion soup mix.

Notes

Bouillon: Different brands vary in saltiness, so adjust to taste. Use 2 tablespoons for a lighter, less salty mix or 4 tablespoons if you want a stronger flavor closer to store-bought packets. 

Paprika: Regular paprika gives a more classic onion soup flavor. Smoked paprika works too, but it adds a subtle smoky note that can change the flavor slightly.

Sugar: The small amount of sugar helps balance the savory flavors and mimics the subtle sweetness found in store-bought mixes. It doesn’t make the mix taste sweet.

How to use: Use 3 tablespoons of this mix to replace 1 packet of onion soup mix in recipes like dips, roasts, or casseroles.

Storage: Store in an airtight container in a cool, dry place. For best flavor, use within 6 months.

Mix before using: The finer powders tend to settle at the bottom. Give it a quick stir or shake before measuring.
