How To Store / Freeze This Salad
- To keep your spinach salad fresh, store the spinach and vegetables separately from the bacon and dressing. Place the spinach in an airtight container lined with a paper towel to absorb excess moisture.
- Store the bacon in a separate airtight container in the refrigerator. This will prevent it from becoming soggy and maintain its crispiness.
- Keep the dressing in a small jar or container with a tight-fitting lid. Refrigerate it and give it a good shake before using it again.
- If you plan to make the salad ahead of time, assemble the spinach, red onion, and mushrooms in a large bowl, but do not add the dressing or bacon until just before serving.
- For freezing, it is not recommended to freeze the spinach salad as the spinach and vegetables will become wilted and lose their texture. However, you can freeze the bacon and dressing separately.
- To freeze the bacon, lay the pieces flat on a baking sheet and place them in the freezer. Once frozen, transfer them to a freezer-safe bag or container. This way, you can take out only the amount you need.
- The dressing can be frozen in small portions using an ice cube tray. Once frozen, pop the dressing cubes out and store them in a freezer-safe bag. Thaw in the refrigerator and warm gently before using.
- When ready to serve, reheat the bacon in a skillet or microwave until crispy. Warm the dressing slightly on the stove or in the microwave, then toss with the spinach and vegetables. Sprinkle the bacon on top and enjoy your fresh-tasting spinach salad.
How To Reheat Leftovers
- Gently reheat the bacon drippings in a skillet over low heat until just warmed. This will help revive the dressing without cooking it further.
- In a separate pan, lightly warm the bacon pieces until they regain their crispiness. Be careful not to overcook them.
- Place the spinach in a large bowl and let it come to room temperature. This will prevent it from wilting too much when the warm dressing is added.
- If the mushrooms and red onion have become too soft, consider adding fresh slices to maintain a crunchy texture.
- Pour the reheated dressing over the salad and toss gently to coat the spinach evenly.
- Sprinkle the reheated bacon on top and serve immediately for the best flavor and texture.
