This french onion soup mix recipe is the one I reach for whenever a recipe calls for that little paper packet and I realize I'm out. It takes five minutes, uses spices most people already have in the cabinet, and tastes closer to homemade than anything from a box.
Spice or coffee grinder - optional, for a finer mix
Digital kitchen scale - optional, for precise measuring
Fine mesh sieve - optional, for sifting out larger pieces
Stainless steel kitchen funnel set - optional, for easy jar filling
Vacuum-sealed storage canister - optional, for extended freshness
Ingredients
1/2cupdried minced onion - 30g
3tablespoonsbeef bouillon granules - 27g
1tablespoondried parsley flakes - 4g
1teaspoononion powder - 3g
1teaspoongarlic powder - 3g
1/2teaspooncelery seed - 2g
1/2teaspoonground black pepper - 1g
1/4teaspoonsmoked paprika - 1g, optional
Instructions
Measure out all ingredients: dried minced onion, beef bouillon granules, parsley flakes, onion powder, garlic powder, celery seed, black pepper, and smoked paprika if using.
Add the dried minced onion and beef bouillon granules to a medium mixing bowl first. Sprinkle in the parsley flakes, onion powder, garlic powder, celery seed, black pepper, and paprika.
Use a whisk or fork to stir everything together until the spices are evenly distributed. Press any clumps of bouillon against the side of the bowl to break them apart.
Spoon the finished mix into an airtight glass jar or spice tin, using a small funnel to avoid spills. Press down gently to remove air pockets, then seal the lid tightly.
Write the date on the jar with a label and store in a cool, dry pantry. Use within six months for best flavor. When a recipe calls for one packet of store-bought mix, use 3 tablespoons of your homemade version.
Notes
Use granulated bouillon, not cubes: Crushed cubes work but don't dissolve as evenly and can leave gritty bits.
Toast the onion flakes lightly first: A quick 30 seconds in a dry skillet over low heat deepens the onion flavor before mixing.
Keep your spices fresh: Old onion powder or garlic powder will make the whole mix taste flat, so check expiration dates.
Don't skip the celery seed: It's the ingredient that makes this taste like the boxed version.
Adjust the salt level yourself: Bouillon granules vary widely in sodium content between brands, so taste before using.
Make a double batch: Since this stores well for months, doubling the recipe means you won't run out.
Grind it finer for dip: A few pulses in a spice grinder gives a smoother texture that blends better into sour cream.
Store away from the stove: Heat and steam from cooking will shorten the shelf life if the jar lives too close to the burners.
For a vegetarian version: Swap the beef bouillon for vegetable or mushroom bouillon granules.
For a low-sodium version: Use a sodium-free or reduced-sodium bouillon and adjust salt to taste.
