Roast Beef & Watercress Sandwich
Elevate your lunch with this quick and satisfying Roast Beef & Watercress Sandwich, featuring tender rare roast beef, zesty horseradish cream, and crisp, peppery watercress on hearty sourdough.
For 1 serving
Gently wash the fresh watercress under cold running water. Pat it thoroughly dry with paper towels or use a salad spinner to remove excess moisture.
If desired, lightly toast the sourdough bread slices until golden brown and crisp. Spread a thin layer of unsalted butter on one side of each slice, if using, for added richness and flavor.
On the unbuttered side (or inner side if not buttering), generously spread 1 tablespoon of horseradish cream on one slice of bread and the remaining 1/2 tablespoon on the other slice.
Arrange the deli-sliced rare roast beef evenly over one of the bread slices, ensuring good coverage without overstuffing.
Pile the dried watercress generously on top of the roast beef. Season lightly with a pinch of freshly ground black pepper and flaky sea salt, if desired, to enhance the flavors.
Carefully place the second slice of bread, cream-side down, on top of the watercress to complete the sandwich. Gently press down to secure the fillings.
For easier eating and a classic presentation, cut the sandwich in half diagonally. Serve immediately to enjoy the fresh textures and vibrant flavors.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1**Quality Ingredients Matter**: Since this is a simple sandwich, the quality of your roast beef and sourdough bread will significantly impact the final taste. Opt for fresh, high-quality deli meat and artisanal bread.
- 2**Toasting for Texture**: Lightly toasting the sourdough adds a delightful crunch and prevents the bread from getting soggy, especially if you're not eating it immediately.
- 3**Dry Watercress is Key**: Ensure your watercress is thoroughly dry after washing. Excess moisture can make the sandwich soggy and dilute the flavors.
- 4**Don't Skimp on Watercress**: The 'large handful' is crucial. The peppery, fresh bite of the watercress is a star component that balances the richness of the beef and cream.
