Ingredients For Spinach Salad With Warm Bacon Mustard Dressing
Spinach: Fresh, vibrant greens that form the base of the salad.
Bacon: Adds a crispy, savory element to the salad.
Red onion: Provides a sharp, tangy flavor and a bit of crunch.
Mushrooms: Adds an earthy taste and texture to the salad.
Bacon grease: Used to create the warm dressing, infusing it with rich, smoky flavor.
Red wine vinegar: Adds acidity and brightness to the dressing.

Technique Tip for This Recipe
To ensure your bacon is perfectly crispy, cook it slowly over medium heat. This allows the fat to render out gradually, resulting in evenly cooked, crispy pieces. Once done, drain the bacon on paper towels to remove excess grease before adding it to the salad. This technique not only enhances the texture but also prevents the salad from becoming too greasy.

How To Store / Freeze This Salad
To keep your spinach salad fresh, store the spinach and dressing separately. Place the spinach in an airtight container lined with a paper towel to absorb excess moisture. This will keep the greens crisp and fresh for up to 2 days in the refrigerator.
Store the bacon mustard dressing in a small, airtight container. When ready to use, reheat the dressing gently in a skillet over low heat or in the microwave for a few seconds until warm. This will ensure the flavors meld beautifully when poured over the salad.
If you have leftover bacon, store it separately in an airtight container in the refrigerator. Reheat the bacon in a skillet or microwave until crispy before adding it to the salad.
Avoid freezing the spinach salad as fresh greens do not freeze well and will become wilted and unappetizing. However, you can freeze the bacon mustard dressing if needed. Pour the dressing into a freezer-safe container, leaving some space at the top for expansion. Thaw in the refrigerator overnight and reheat gently before using.
For best results, assemble the spinach salad just before serving. This ensures the spinach remains crisp and the dressing is warm and flavorful, providing the perfect contrast in textures and tastes.
