We've adapted the classic roast into a buffet-style, serve-yourself dish, with options: make a sandwich (with cornichons and horseradish sauce) if you want, or eat it up as distinct components if that's more your thing. Store-bought rolls that have been reheated, brushed with butter, and sprinkled with flaky salt might not be the same as homemade, but they will impress nonetheless.

Preparation
Step 1
Lightly score fat cap of roast, spacing cuts about 3/4" apart, with a sharp knife, being careful not to slice into the flesh. Season roast generously on all sides with salt and pepper. Mix garlic, rosemary, and 3 Tbsp. oil in a small bowl and rub all over roast. Loosely cover with plastic wrap and chill at least 12 hours and up to 2 days.
Step 2
Preheat oven to 200°F. Place roast on a wire rack set inside a large rimmed baking sheet. Roast until an instant-read thermometer inserted into the thickest part of meat registers 118°F–120°F for medium-rare, about 2 1/2 hours. Let rest 1 hour (internal temperature will continue to climb to 125°F–130°F).
Step 3
Mix together yogurt, sour cream, horseradish, and lemon zest in a small bowl; season sauce with salt.
Step 4
Heat remaining 2 Tbsp. oil in a large skillet over medium. Cook roast just until browned, about 2 minutes per side. Transfer to a cutting board and thinly slice. Serve with horseradish sauce, rolls, and cornichons.
Do Ahead
Step 5
Beef can be roasted and browned 3 days ahead. Cover and chill. Let sit at room temperature 1–2 hours before serving.
