Ingredients for Spinach Salad with Warm Bacon Mustard Dressing
Spinach: Fresh and washed, this leafy green is the base of the salad.
Bacon: Adds a crispy, savory element to the salad.
Red onion: Provides a mild, sweet flavor and a bit of crunch.
Mushrooms: Adds an earthy taste and texture to the salad.
Apple cider vinegar: Gives the dressing a tangy kick.

Technique Tip for This Recipe
When cooking the bacon, make sure to render out as much fat as possible to achieve a crispy texture. This will not only enhance the flavor but also provide a rich base for the warm bacon mustard dressing. To do this, cook the bacon slowly over medium heat, allowing the fat to melt away gradually. Once the bacon is crispy, remove it from the skillet and drain on paper towels, but be sure to leave the drippings in the pan for the next steps.

How To Store / Freeze This Salad
To keep your spinach salad fresh, store the spinach and dressing separately. Place the washed and dried spinach in an airtight container lined with paper towels to absorb excess moisture. This will help maintain its crispness.
For the bacon, cook it until crispy and then let it cool completely. Store the cooled bacon in a separate airtight container or a resealable plastic bag. This will prevent it from becoming soggy.
The warm bacon mustard dressing can be stored in a small jar or airtight container. Keep it in the refrigerator for up to 3 days. When ready to use, reheat the dressing gently in a skillet over low heat or in the microwave in short bursts, stirring frequently.
If you have leftover salad that is already dressed, it’s best to consume it within a day. The spinach will wilt and lose its texture if stored for too long with the dressing.
To freeze the bacon, lay the cooked pieces on a baking sheet lined with parchment paper and freeze until solid. Once frozen, transfer the bacon to a resealable plastic bag or airtight container. This method prevents the pieces from sticking together. The bacon can be frozen for up to 1 month.
Do not freeze the spinach or the dressing. Freezing will cause the spinach to become mushy and the dressing to separate and lose its consistency.
When ready to serve, combine the fresh spinach, reheated bacon, and dressing just before eating to ensure the best texture and flavor.
