Nick’s roast beef is a simple oven-roasted beef roast seasoned with garlic, herbs, and black pepper, then sliced for a classic dinner or sandwiches. A hot start builds a browned exterior, while finishing at a lower temperature helps the center cook evenly; the best doneness depends on a thermometer, not the clock alone.
Ingredients
- 1 boneless beef top sirloin roast, 3 lb (1.36 kg), preferably tied by the butcher
- 1½ tbsp olive oil (22 ml)
- 2 tsp kosher salt (10 g; use about 1½ tsp table salt if substituting)
- 1½ tsp freshly ground black pepper (3 g)
- 3 garlic cloves, finely grated or minced (about 1 tbsp / 9 g)
- 1 tbsp chopped fresh rosemary (3 g), or 1 tsp dried rosemary (1 g)
- 1 tbsp chopped fresh thyme leaves (3 g), or 1 tsp dried thyme (1 g)
- 1 medium yellow onion, cut into wedges (about 1 cup / 150 g)
- 1 cup low-sodium beef broth (240 ml), for the roasting pan
Instructions
- Take the chill off and prepare the oven. Remove the roast from the refrigerator about 30 minutes before cooking; keep it on a plate and do not leave it out longer than 2 hours total. Heat the oven to 450°F (230°C). Pat the beef dry with paper towels so the surface can brown.
- Season the roast. Stir together the olive oil, salt, pepper, garlic, rosemary, and thyme. Rub the mixture over every side of the beef. Put the onion wedges in the bottom of a roasting pan and set a rack over them. Place the roast fat-side up on the rack. Pour the broth into the pan beneath the rack, not over the meat.
- Roast hot, then lower the heat. Roast at 450°F (230°C) for 15 minutes to brown the outside. Without opening the oven for long, reduce the temperature to 325°F (165°C) and continue roasting. Begin checking the center with an instant-read thermometer after about 50 minutes at the lower temperature. Insert it into the thickest part, away from the rack or any large pockets of fat. Continue cooking as needed; a 3-pound roast commonly takes about 1 hour 15 minutes to 1 hour 30 minutes total, but shape and oven differences matter more than the estimate.
- Cook to a safe temperature. The USDA FSIS safe minimum for a whole cut of beef is 145°F (63°C), followed by a 3-minute rest. For a pinker roast, remove it from the oven at 145°F (63°C) and rest for at least 3 minutes; the temperature may rise a little as it rests. Do not rely on color to judge safety. If cooking for guests who prefer more doneness, continue roasting and check frequently, removing the roast at their preferred temperature.
- Rest, then carve. Transfer the beef to a cutting board and loosely tent it with foil. Rest for 20 minutes before slicing; this is additional resting time, not a substitute for the 3-minute food-safety rest. Strain the pan juices if desired and spoon off excess fat. Slice the roast thinly across the grain and serve with the juices.
Tips
- Use the thermometer as your guide. A roast’s shape, starting temperature, and oven accuracy all affect cooking time. Check in more than one nearby spot if the roast is uneven, and avoid touching the pan with the probe.
- Choose a suitable cut. Top sirloin is flavorful and slices neatly. A top round or eye of round roast can also work, though they are leaner and may be less tender; slice them especially thinly across the grain. A fattier rib roast will be richer and usually costs more.
- Keep the surface dry. Moisture on the beef inhibits browning. Pat it dry before seasoning, and make sure the broth stays below the rack. If the pan dries out, add a little more broth or water so the drippings do not scorch.
- Adjust the salt thoughtfully. Kosher salt crystals vary in size by brand, so measure by weight when possible. If using salted broth, reduce the added salt slightly; you can season sliced portions at the table.
Serving Suggestions
Serve warm slices with roasted potatoes, mashed potatoes, or Yorkshire pudding, plus a green vegetable such as green beans or broccoli. The onions and strained pan juices make a simple accompaniment; for a thicker gravy, whisk 1 tablespoon flour (8 g) into 1 tablespoon fat skimmed from the pan, cook briefly, then gradually whisk in the pan juices and enough broth to reach your preferred consistency.
For sandwiches, cool the roast until easy to handle and slice it thinly. Serve on rolls with horseradish, mustard, or a little warm pan juice. Keep sauces and toppings separate until serving, especially if you plan to store extra meat.
Variations
Mustard-herb crust: Replace the olive oil with 1 tablespoon Dijon mustard (15 g) and keep the garlic and herbs. The mustard adds tang and helps the seasoning cling; it will not make the roast taste strongly of mustard.
Simple pepper and garlic: Skip the rosemary and thyme and use an additional ½ teaspoon black pepper. This more straightforward seasoning works well for sandwiches and lets the beef flavor lead.
Red-wine pan juices: Replace half the broth with ½ cup dry red wine (120 ml). Add it to the pan before roasting; the resulting juices will have a deeper, slightly more acidic flavor. Do not pour liquid over the seasoned roast.
Different herbs: Use 1 teaspoon dried Italian seasoning (about 1 g) in place of the fresh rosemary and thyme. Dried herbs are more concentrated, so avoid swapping them one-for-one by volume.
Storage and Reheating
Refrigerate cooked beef within 2 hours of cooking, storing it in a shallow airtight container with a little pan juice to limit drying. It keeps for 3–4 days in the refrigerator. For longer storage, freeze it in airtight, meal-size portions for about 2–3 months for best quality; thaw in the refrigerator.
Reheat only the amount you plan to eat. Warm slices gently in a covered skillet with a splash of broth or pan juice, or in a covered oven-safe dish at 300°F (150°C), until the leftovers reach 165°F (74°C). Check with a food thermometer. Microwave reheating also works: cover the meat, add a little liquid, and heat in short intervals, turning or rearranging the slices for even heating. Reheating past the safe temperature can make lean roast beef dry, so avoid prolonged heating.
Frequently Asked Questions
How long does a 3-pound roast beef take to cook?
For this method, expect roughly 1 hour 15 minutes to 1 hour 30 minutes in the oven, including the initial hot-roast period. The exact time varies with the roast’s shape and your oven, so use a thermometer rather than treating the estimate as a guarantee.
Should roast beef be covered while it cooks?
No. Roast it uncovered so the exterior browns. After it comes out of the oven, loosely tent it with foil while it rests; sealing it tightly can soften the browned surface.
Can I make this with a frozen roast?
Thaw the beef completely in the refrigerator before roasting. A frozen or partly frozen roast cooks unevenly, making it harder to reach a safe temperature throughout and to time the meal accurately.
Why should I slice roast beef across the grain?
The grain is the direction in which the muscle fibers run. Cutting across those fibers shortens them, making each bite easier to chew. If the direction changes along the roast, turn the meat as needed while carving.
Can I prepare the seasoning in advance?
Yes. Mix the oil, salt, pepper, garlic, and herbs up to a day ahead and refrigerate it in a covered container. Apply it shortly before roasting; refrigerate the raw seasoned beef if you prepare it early, and do not reuse any mixture that has touched raw meat.
Is pink roast beef safe to eat?
Color alone cannot tell you whether beef is safe. For a whole cut, check that the center reaches the USDA FSIS minimum of 145°F (63°C) and allow at least a 3-minute rest, using a food thermometer.
