Time
- Prep: 15 min
- Cook: 1 hr 45 min
- Total: 10 hr 15 min (8 hr inactive)
Servings: 8
Serving: about 4 thin slices (120 g / ~4 oz)
Ingredients
Roast Beef
- Top round beef roast: ~1.25 kg (~2¾ lb) — or top sirloin, eye of round
- Kosher salt: 10 g (≈2 tsp) — for dry brine
- Black pepper: 1 tsp
- Garlic powder: 1 tsp — optional
- Onion powder: 1 tsp — optional
- Neutral oil: 1 Tbsp — for searing
Instructions
1. Dry-brine (recommended)
- Pat ~1.25 kg (~2¾ lb) top round beef roast dry. Mix 10 g (≈2 tsp) kosher salt, 1 tsp black pepper, and optional 1 tsp garlic powder / 1 tsp onion powder; season all over.
- Refrigerate uncovered on a rack 8–24 hours. If skipping, season at least 30 minutes before cooking.
2. Preheat and sear
- Heat oven to 275°F / 135°C.
- Heat 1 Tbsp neutral oil in an oven-safe skillet over medium-high. Sear roast on all sides until browned, 6–8 minutes total.
3. Roast to temperature
- Insert a probe or check with an instant-read thermometer. Roast at 275°F until:
- 125–130°F / 52–54°C (medium-rare)
- 135–140°F / 57–60°C (medium)
- Typical time for a 2½–3 lb roast: 1½–2 hours. Go by temperature, not minutes.
4. Rest
- Transfer to a board and rest 20 minutes to redistribute juices.
- If making French Dip + Au Jus next, you may leave the roast whole and proceed to deglaze the pan in that recipe.
5. Slice thin
- For deli-thin slices, chill the rested roast 30–60 minutes (optional), then slice very thinly against the grain (1–2 mm).
6. Serve or hold
- Use immediately or keep slices covered and refrigerated. For hot applications, briefly swish slices in hot jus/stock or steam 10–20 seconds.
Notes / Make-ahead / Variations
- Cuts: top sirloin is most tender; top round/eye of round are leaner and slice well.
- Searing vessel: if you roasted on a rack over a sheet pan, deglaze the sheet pan later for au jus; if you seared/roasted in a skillet or roasting pan, deglaze that same pan.
- Doneness: pull 5°F / 3°C below target; carryover will finish the cook.
- USDA safe-minimum guidance for beef roasts is 145°F / 63°C with a 3-minute rest; use higher endpoint temperatures for risk-sensitive guests.
- Seasoning: thyme or rosemary can be added to the rub; keep surface fairly dry for better browning.
Storage & reheating
- Whole roast: up to 4 days refrigerated, tightly wrapped. Slice to order for best texture.
- Sliced: up to 3 days refrigerated. Reheat gently by dipping in hot jus/stock; avoid prolonged microwaving.
