Steps
Before you start
- Wash and thoroughly dry the watercress and endive using a salad spinner or paper towels
- Have all vinaigrette ingredients measured and ready
- Toast the walnuts just before tossing the salad for maximum freshness and crunch
Toast the walnuts
- Place the walnut halves in an 8-inch (20 cm) skillet over medium heat.
- Toast for 4–5 minutes, shaking the pan occasionally, until fragrant and lightly golden brown.
- Transfer to a plate to cool slightly.

Ready when: Fragrant and lightly golden brown
Tip: Don't let them burn—walnut oils can become bitter at high heat. Shake the pan frequently to ensure even toasting.
Whisk the vinaigrette
- Mince the shallot finely.
- In a small bowl, whisk together minced shallot, red wine vinegar, and Dijon mustard.
- While whisking constantly, slowly drizzle in the olive oil in a thin stream until the vinaigrette is fully emulsified and creamy.
- Season generously with salt and freshly ground black pepper to taste.

Ready when: Vinaigrette is emulsified, creamy, and well combined
Tip: Add the oil in a thin, steady stream while whisking—this creates a proper emulsion and prevents the vinaigrette from breaking. If it separates, start over with fresh vinegar and whisk in the broken emulsion slowly.
Trim and slice the greens
- If not already done, wash and thoroughly dry the watercress and endive using a salad spinner or paper towels.
- Trim the root ends from the endive heads.
- Slice each endive head crosswise into 1-inch (2.5 cm) pieces, separating the leaves naturally.
- Tear any large watercress sprigs in half for uniform size.

Tip: Thoroughly drying the greens is essential—any excess water dilutes the vinaigrette and dulls the flavors. Use a salad spinner if available, or pat dry with a clean, lint-free towel.
Toss and serve
- In a large bowl, combine the toasted walnuts, watercress, and endive slices.
- Pour the vinaigrette over the salad and toss gently but thoroughly until all the greens are evenly coated.
- Divide among serving plates or a shallow bowl and serve immediately while the walnuts are still warm and the greens are crisp.

Good to know
Tips
- Choose bright, tender watercress and pale, crisp endive for the best flavor and texture; avoid wilted or yellowing leaves.
- Toast the walnuts just before assembling—toasted nuts lose their fragrance and crunch after sitting for several hours.
- The vinaigrette's acidity balances the bitter greens; adjust the vinegar-to-oil ratio slightly if you prefer more or less tang.
- This salad is perfect as a first course before a rich main dish; the bitter greens aid digestion and refresh the palate.
Make ahead
The vinaigrette can be made up to 2 days ahead and stored in a covered jar in the refrigerator. Assemble and dress the salad just before serving so the greens remain crisp and bright.
Storage & reheating
This salad is best served immediately after tossing. Leftover vinaigrette can be stored in a covered jar in the refrigerator for up to 1 week and reused on other salads. Store any undressed greens in a sealed container or bag for up to 3 days.
Substitutions
- unsalted walnuts, halves → toasted hazelnuts or pecans. Provides similar nutty flavor and crunch; toast the same way
- Belgian endive, large → radicchio or chicory. Offers similar bitterness and crispness; use the same quantity
- fresh watercress → arugula or mustard greens. Provides peppery bite and slight bitterness; use equal quantity
- red wine vinegar → sherry vinegar or aged balsamic vinegar. Use equal quantity; sherry vinegar is more delicate, balsamic is richer and darker
