Why This Recipe Works
Ingredients for Recipe
1/4 cup dried onion flakes: The star of the mix, providing that rich onion flavor. You can find dried onion flakes at most grocery stores, or use a dehydrator for homemade flakes.
1 tablespoon onion powder: Adds a second layer of onion flavor without being too overpowering.
1 tablespoon garlic powder: A must-have for the savory depth. You can use granulated garlic if you prefer a finer texture.
1 teaspoon dried parsley: This herb adds a subtle freshness that balances the richness of the onions and garlic.
1 teaspoon dried thyme: Complements the onion flavor with an earthy, herby note.
1/2 teaspoon salt: Enhances all the flavors and rounds out the mix.
1/4 teaspoon ground black pepper: Adds a gentle hint of spice and complexity.
1/4 teaspoon paprika: For a touch of sweetness and warmth, you can use smoked paprika for a smoky depth.
Step-by-Step Instructions
- Mix the Ingredients: In a small bowl, combine the dried onion flakes, onion powder, garlic powder, dried parsley, dried thyme, salt, pepper, and paprika.
- Stir Well: Using a spoon, stir the mixture thoroughly to ensure that all the ingredients are evenly distributed.
- Store: Transfer the homemade onion soup mix to an airtight jar or container. Store in a cool, dry place for up to 6 months.
Chef’s Insight: Don’t forget that this onion soup mix is just as good for seasoning other dishes. You can sprinkle it over popcorn, stir it into mayonnaise for a quick dip, or add it to any dish that could use a little flavor boost.
Pro Tips & Common Mistakes to Avoid
If you prefer a finer texture, grind the dried onion flakes in a spice grinder before mixing. This will give the mix a smoother consistency and make it dissolve faster when cooking.
To make it even more flavorful, add a pinch of cayenne pepper for some heat or dried celery flakes for a subtle depth.
Overdoing the salt. This mix can become very salty if you’re not careful, so it’s best to start with less salt and adjust to taste when using it in recipes.
Not letting the mix “rest” before using it. Give it a few hours for the flavors to meld together in the jar, making it even more flavorful.
