How to Store / Freeze This Recipe
- Ensure the dry onion soup mix is stored in an airtight container to maintain its freshness and potency. A glass jar with a tight-fitting lid or a resealable plastic bag works perfectly.
- Label the container with the date of preparation. This helps you keep track of its shelf life, which is typically around 6 months when stored in a cool, dark place like a pantry.
- For longer storage, consider placing the dry onion soup mix in the freezer. This can extend its shelf life up to a year. Make sure the container is freezer-safe and properly sealed to prevent any moisture from getting in.
- When ready to use, allow the mix to come to room temperature if it was stored in the freezer. This ensures that the flavors are well-balanced and the mix is easy to measure.
- Keep the mix away from direct sunlight and heat sources, as these can degrade the quality of the spices and herbs over time.
- If you notice any clumping or changes in color or smell, it’s best to discard the mix and prepare a fresh batch. This ensures that your soups and other dishes always taste their best.
