First, measure out all spices, herbs and powders into a small mixing bowl:

2 tbsp beef bouillon

2 tbsp cornstarch

2 tsp onion powder

1 tsp dried parsley

1/8 tsp black pepper

1/8 tsp garlic powder

Tip: Use a digital kitchen scale for most accurate measurements.

Now blend everything together thoroughly using a fork, whisk or electric mixer on low speed. Keep mixing until the texture becomes a homogeneous powder.

Tip: Use a blender or food processor to grind ingredients into a fine, consistent powder.

Finally, spoon your spice blend into an airtight jar, tin or zip-top bag. Push out excess air before sealing and store somewhere cool, dark and dry.

Tip: Write the recipe name and date on the container so you know what it is and when it was made.

And that's it - you just made your own batch of homemade au jus seasoning from a few pantry staples! It will stay fresh for up to 6 months when stored properly.

Now you're ready to transform this blend into incredibly flavorful au jus gravy whenever a recipe calls for it.
