Ingredients

Best Matches

1:1 Homemade onion soup mix (dried onion + onion powder + beef bouillon powder + garlic powder) Closest “packet” flavor; make extra for repeat swaps.
1:1 French onion dip mix (dry powder) Onion-forward and savory; reduce slightly if the dip mix tastes creamy/sweet.

Good Alternatives

1:1 Instant onion gravy mix Adds body; whisk with a splash of water/broth first when used as a sauce.
¾:1 ratio Onion powder + beef bouillon powder blend Use this when you only have pantry spices; it’s less “packet-like” but very close in savoriness.

Emergency Swaps

1:1 Vegetable bouillon powder + dried onion (or minced onion flakes) Vegetarian depth; watch for missing beefy richness—add a pinch of garlic/pepper.
1:1 Mushroom bouillon powder + onion powder Umami substitute when onion flavor is still available via onion powder.

Method

Choose a substitute from the list based on what you have: a dry onion-forward mix (best), a gravy/powder blend (good), or bouillon + onion spices (emergency).
Start with the listed ratio (usually 1:1); if your recipe already uses broth, taste first and reduce by 10–25% to avoid excess salt.
If using a gravy mix, dissolve/whisk it briefly in a small splash of broth or water before adding to prevent clumps.
In slow-cooked dishes or baked casseroles, stir the substitute in early so the onion flavor fully blooms.
Finish by adjusting: add a pinch of garlic/pepper for depth, or a tiny squeeze of lemon/vinegar if the blend tastes flat.

Notes

Salt check: onion soup mix is typically salt-forward; if your dish already has soy sauce, salted broth, or Worcestershire, scale down.
Packet swaps work best when you match the role: dry seasoning for rubs vs dissolved mix for sauces.
