Method
Preheat your oven to 175°C/350°F. Pat the sirloin roast completely dry with paper towels. Season aggressively on all sides with salt and cracked black pepper.
In a large skillet or roasting pan over medium-high heat, add the vegetable oil. Sear the beef on all sides until a deep brown crust forms, about 3-4 minutes per side.
Remove the beef from the pan temporarily. Add the onions, carrots, celery, garlic, and thyme to the pan. Sauté for 3-4 minutes until slightly browned. Place the roasting rack over the vegetables and set the beef on top. Transfer to the oven.
Roast until an instant-read thermometer inserted into the thickest part of the beef reads 52°C/125°F for medium-rare. Carryover cooking will raise the temperature further during resting.
Transfer the beef to a cutting board and tent loosely with foil. Let it rest for at least 20 minutes. Do not skip this step, or the juices will run out.
Place the roasting pan with the vegetables back on the stove over medium-high heat (or transfer contents to a pot). Add the red wine to deglaze, scraping up the browned bits (fond) from the bottom. Simmer until reduced by half.
Add the beef stock and Worcestershire sauce. Bring to a simmer and cook for 10-15 minutes to marry the flavors. Strain the liquid through a fine mesh sieve into a clean saucepan, pressing on the vegetables to extract all flavor. Discard vegetables. Keep the jus warm.
Slice the baguettes open and butter the insides. Toast briefly under a broiler or in a toaster oven. If using cheese, place slices on the bread and melt under the broiler for 1 minute.
Slice the rested beef as thinly as possible against the grain. Pile generous amounts of beef onto the toasted bread. Serve immediately with individual bowls of warm jus for dipping.
Chef's Notes
- To achieve deli-style thin slices at home, place the rested, cooked beef in the freezer for 15-20 minutes before slicing. This firms up the meat and allows for much thinner cuts.
- The 'jus' is not a thick gravy; it is a broth. Do not thicken it with flour or roux unless you prefer a non-traditional dipping sauce.
- Top Sirloin is flavorful but leaner than ribeye. Do not cook it past medium (60°C/140°F) or it will become dry. The dipping sauce helps, but proper cooking is key.
- Toast the bread thoroughly. The crust needs to be sturdy enough to hold the wet beef and survive the dip without disintegrating immediately.
Storage
Refrigerator: 3 days — Store beef and jus in separate airtight containers to prevent bread sogginess.
Freezer: 2 months — Freeze sliced beef in the jus to prevent freezer burn.
Reheating: Gently warm beef in the jus over low heat until heated through. Do not boil or the meat will toughen.
