The 5 Best Substitutes for Onion Soup Mix

Have you ever wondered why onion soup mix is a common pantry staple?

It’s incredibly versatile, allowing for diverse flavors and tastes in one simple packet.

Whether you’re looking to add a depth of flavor to your brunch side dish or the perfect umami seasoning for dinner, an onion soup mix can be the answer.

While it typically requires a few ingredients to cook, there are some alternatives that give delicious results when you don’t have that traditional onion soup packet on hand.

Read on to learn how to substitute and what are the five best substitutes for onion soup mix.

What’s Onion Soup Mix?

Onion soup mix is a savory multi-flavor seasoning that can be used to give dishes an added depth of flavor.

It contains a combination of herbs, including onion, garlic, and parsley, with other seasonings like paprika, chili peppers, and celery seed.

It has a salty taste and crunchy texture from the small number of freeze-dried vegetables, which can be recognized in the mix.

Onion soup mix is great to use when cooking all types of dishes as it provides robust flavors that are not overpowering.

For example, you can use it as a coating for baked fish, stir-fry vegetables on the stove top, or add a sprinkle to roasted chicken.

No matter how you choose to use it, the onion soup mix is sure to provide your favorite recipes with extra flavorings beyond basic salt and pepper.

The 5 Best Substitutes for Onion Soup Mix

If you’re looking for an onion soup mix substitute, you’re in luck.

There are several tasty options that can be used as a replacement for store-bought onion soup mix.

Here are the five best substitutes for onion soup mix:

1 – Dried Onion Flakes

Dried onion flakes are an ingredient commonly used in soups, stews, and sauces for a powerful hit of onion flavor without the hassle of buying and dealing with raw onions.

Dried onion flakes have a strong scent and deep, sweet taste that will add complexity to any dish.

They also embody the same texture as chopped onions.

Instead of using a store-bought onion soup mix, you can easily substitute it with some dried onion flakes, some beef bouillon cubes, a pinch of garlic powder, and a sprinkle of dried parsley.

This is not only cost-effective but is sure to give your meal that extra flavor boost.

2 – Caramelized Onions

Caramelized onions are a delicious way to add robust flavor to any dish.

They are made by slowly cooking onions in butter or oil over low heat in order to draw out their sweet and savory notes for an altogether unique taste.

These slow-cooked onions bring a depth of flavor to dishes, with a delicate but distinctly onion flavor.

Their texture becomes soft and jam-like but still retains some snap.

Caramelizing onions is one of the best ways to use them instead of onion soup mix – sautéed onion slices have a very comparable flavor, as well as provide a beautiful garnish or topping for other foods.

3 – Onion Powder

Onion powder is an incredibly convenient way to add the perfect amount of onion flavor to your recipes.

It’s available in both a granular and fine powder form, giving cooks the flexibility to choose which texture works best for their dish.

Onion powder features a pungent and sweet taste with subtle hints of garlic, making it an essential seasoning for many recipes.

To substitute onion soup mix, you can make your own by combining equal parts onion powder, celery salt, and either paprika or turmeric with garlic powder if desired.

Altogether this creates a more intense flavor than its canned counterpart, making it the superior choice in dips, casseroles, and stews.

4 – Fresh Green Onions

Fresh green onions, also commonly referred to as scallions, bring a vivid kick of flavor to all sorts of dishes.

With a mild taste and slight spiciness, they add an extra layer of flavor without overpowering the other ingredients.

These delicate onions have a tender texture but retain their crunch even after being cooked.

To get that same oniony taste with less mess in the kitchen, some recipes suggest swapping out fresh green onions for dried onion soup mix.

Less hassle and still packed full of flavor – what could be better?

5 – Mix of Dried and Fresh Herbs

Using a mix of fresh and dried herbs is the perfect way to heighten the flavor of your cooking.

Within the mix are chives, oregano, thyme, basil, garlic, and onion – all working together to create a unique blend of earthy and bright flavors.

The combination adds layers of taste while still retaining its subtlety.

In addition to flavor, this mix enriches the texture of recipes with its assorted sizes and shapes of granules – from large lumps of basil to finely milled onion.

If you’re looking for an alternative to an onion soup mix usually found in soup or casserole recipes, this blend can make for a tasty substitution.

Just use the one-quarter cup for each envelope you would normally add – voila – a flavorful upgrade.


In conclusion, an onion soup mix is a great way to add flavor and depth to all sorts of dishes.

However, there are some equally delicious alternatives that can be used as substitutes.

Whether it’s dried onion flakes, caramelized onions, onion powder, fresh green onions, or a mix of herbs – you can rest assured that your recipes will still be full of flavor and texture.

Make sure that you experiment with different amounts of each ingredient to find the perfect combination for your taste buds.
