Hack #1: Transform Leftover Small Onions into Onion Powder

We’ve all been there—chopping up an onion for one recipe and having half left over. Instead of letting it go bad, why not make your own onion powder? It’s surprisingly easy and lets you control the quality and intensity of the flavor.

Step-by-Step Process:

1. Chop the onions finely—the smaller the pieces, the faster they’ll dry.
2. Dehydrate or oven-dry until completely crisp (more on methods later).
3. Grind into powder using a spice grinder or high-speed blender.
4. Store in airtight containers for up to 6 months.

Pro Tip: Mix different types of onions—yellow, red, even sweet—for a custom flavor blend that outshines anything from the grocery store shelf.

Hack #2: Dehydrator vs. Oven – Which Works Best?

METHOD	PROS	CONS	BEST FOR
Food Dehydrator	Even drying, preserves flavor and nutrients better	Takes longer (~8–12 hours)	Spice lovers who want top-quality results
Oven (Low Temp)	Faster, no extra appliance needed	Risk of burning or uneven drying	Quick fixes and small batches

If you’re serious about making spices at home, investing in a food dehydrator like the Excalibur 3926TB can make a big difference in texture and potency. However, if you’re just trying it out, your oven set to its lowest temperature (around 150°F / 65°C) works fine—just keep an eye on it and stir occasionally.

Hack #3: Proper Storage Techniques for Homemade Onion Powder

Once you’ve gone through the trouble of making your own onion powder, you want to keep it tasting fresh as long as possible. Here’s how to store it like a pro:

• Airtight containers: Mason jars or amber glass bottles block light and keep moisture out.
• Cool, dark place: A pantry or kitchen cabinet away from heat sources is ideal.
• Label everything: Write the date and type of onion used so you know when to use it up.
• Vacuum-seal for longevity: If you have a vacuum sealer, seal portions for long-term storage (up to a year).

Hack #4: Creative Uses Beyond Sprinkling on Food

Onion powder isn’t just for soups and stews. Try these fun ways to use your homemade spice:

• Season grilled meats before roasting or barbecuing.
• DIY seasoning blends like Cajun or Italian herb mixes.
• Add to popcorn for a savory snack.
• Boost salad dressings and dips without adding liquid.
• Make onion butter by mixing with softened butter and herbs.
