Step 1

In a small bowl, place the onion powder, garlic powder, sugar, salt, cornstarch, minced dried onions, and beef bouillon granules.

Step 2

Whisk to combine well. Set the bowl aside or transfer to a small glass container using a small funnel or by placing the ingredients on a piece of parchment paper, rolling the paper toward the center, and letting the ingredients slide into the container.

Step 3

Place the mayonnaise and sour cream in a medium-size bowl, and whisk to combine well.

Step 4

Add the dry onion soup mix ingredients, and whisk to combine well.

Step 5

Cover the bowl and place it in the refrigerator to chill for at least an hour (to allow the dried onions to soften) and up to 3 days.

Step 6

Serve in a serving bowl, with chips, celery, or carrot sticks for dipping.
