What Is Onion Soup Mix?

Homemade Onion Soup Mix is a dry blend that is primarily used for slow cooker roasts, soups, meatloaf, or dips! This recipe is very simple but the strong flavors do a lot for a dish with just a little bit of this seasoning.

Here is your ingredient list:

• Dried minced onion
• Onion powder
• Garlic powder
• Salt
• Black pepper
• Beef bouillon powder

To make this mix into a dip add two tablespoons to two cups of sour cream. Taste and adjust, add more onion soup mix if it is not strong enough. You could also lessen the flavor by adding a half cup of mayonnaise.

How much homemade onion soup mix equals one packet?

Most store-bought onion soup mix packets contain about 1 ounce, which is roughly 3 to 4 tablespoons of dry mix.

For this homemade version, use:

👉 3 tablespoons for a lighter flavor
👉 4 tablespoons for a stronger, classic flavor

You can always adjust slightly depending on the recipe.

🥣 Can I make onion dip with this mix?

Yes! This mix works perfectly for classic onion dip.

To make dip:

• 1 cup sour cream
• 1–2 tablespoons homemade onion soup mix

Stir well and refrigerate for at least 30 minutes before serving so the flavors can develop.

For a thicker dip, use Greek yogurt. For a richer dip, mix half sour cream and half cream cheese.

🥩 Can I use this for slow cooker pot roast?

Absolutely. This is one of the most popular ways to use onion soup mix.

Sprinkle 3–4 tablespoons over a chuck roast, add a little broth or water, and cook on low for 8 hours. It creates a savory, flavorful gravy as it cooks.

You can also combine it with your homemade beef bouillon for even deeper flavor.

🧂 Is homemade onion soup mix gluten-free?

It can be, depending on your ingredients.

Most of the base spices are naturally gluten-free. Just make sure your bouillon powder is labeled gluten-free or make it yourself if that’s important for your household.

⏳ How long does homemade onion soup mix last?

When stored in an airtight container in a cool, dry place, this mix will stay fresh for 6–12 months.

For best flavor, give the jar a quick shake before each use to redistribute the spices.

🥘 Can I use this mix to make actual onion soup?

Yes — but you’ll need additional ingredients.

To make onion soup:

• Sauté sliced onions in butter until caramelized
• Add beef broth (or broth made from your bouillon)
• Stir in 1–2 tablespoons of this mix
• Simmer until flavorful

Top with toasted bread and cheese for a classic finish.

It adds deep onion flavor without chopping fresh onions.
